Chevrolet - Suburban :: 1994 - Won't Engage The Front Drive Shaft
My 1994 Chevy Suburban will not engage the front drive shaft. It has an electric actuator and it will not engage. the transfer case engages but not the front axal. When I shift the transfer case into 4Hi or 4Low it will shift itself but the light will not turn on. I have heared rumors that you might have to manualy connect it to the battery and have a kill switch in the cab. What is the problem and should I connect it manualy?

I have a 03 Suburban LT with the 150,000 miles. and it misses out at 50mph or higher. I thought it was the transmission, and the tranny guy confirmed a new transmission was needed, but said he thought the missing was maybe the coils. the local Chevy dealer did the diagnostic, and determined the coils, plugs, and plug wires were all good. I 've replaced the oxygen sensor as well. The service manager said to keep driving it until the Check Engine light comes on. That concerns me, but hey what do I know. The mileage hasn't dropped off, and it runs fine the rest of the time.

I have a failing 2003 Chevy Suburban instrument cluster and wonder if I can replace it myself. All I have to do is remove it and re-install it when they send it back. 4 bolts and one plug. No reprogramming. What could be easier? Is it really something I can/should do? -

First i know this subject has been covered, but i am at a loss. I have a 1997 burb 2wd that started the shake right after i bought it. it shake from around 65 to just under 75. Here is the list of items I have done by reading the forums. I am on 2nd set of tires both different brands. Last set has been road force balanced new inner and outer tie rods new shocks new rear trans mount new front and rear u joints had drive shaft rebalanced new front wheel bearings this is also the other stuff that has been done in last 6 months new a/c compressor and lines new alternator new radiator new plugs , cap, rotor, wires. It is hard for me to tell where the shake is coming from as sometimes it fells like the whole truck and other times just the front end. at this speed i also have put the truck in neutral and let it idle down and still nothing.
View 2 RepliesChevrolet - Tahoe :: 2003 - Die Almost Every Stop / Can't Drive When Tank Reaches 1/4
So far, I have a small fortune into fixing this / related problems. I'll state what we've done and what is currently happening. I've taken it to my normal mechanic several times, I'm looking for additional opinions because they basically have no idea. This is on our 2003 Chevy Tahoe, my wife's daily driver, and what my kids are normally riding in. It only has about 60K actual miles on it and is a flex fuel model, if that matters.
Originally, the truck would have trouble starting. Cranking, but no ignition. Waiting a a few seconds, try to crank again and it would start up. This went on for about a week and then it stopped cranking cranking at all. Had it towed to our mechanic. PCM B fuse was blown. Replaced PCM B Fuse (20A) and it blew again after starting. It died while trying to idle. They did some voltage drop tests, seemed good. I'm not sure they did any current tests at the fuel pump which is on that fuse. Ended up there for 4 days (yes, lots of labor) and leaving with no real clue, but a 25A fuse would work.
A week later,we were still having problems (but my memory is a bit shady). The mechanic did some pressure tests and bleed tests and said that our fuel pump was outside the specified pressure and needed to be replaced. Dropped tank, replaced pump and sending unit with a new AC Delco, replaced fuel filter. Took it home, it seemed great.
Then my wife called me and said her truck was dying at every stop sign. When she got home, I verified, the tank read 1/4 full, truck would die at almost every stop. Truck would die slowing from 45 to 20 mph to make a left turn. This was dangerous, took it back to mechanic. Mechanic couldn't find an issue, but figured it was the sending unit. Replaced the part under warranty, didn't charge me any labor. They thought that we were really empty at 1/4 tank and had a bad sending unit, but that doesn't seem to be the case now.
Here are the basics of where we are: Truck runs fine when above 1/4 tank of gas.The truck suddenly dies when stopping or slowing down when the gas gauge reaches 1/4 tank. Starts right back up with no struggle, otherwise runs fine when the tank is low..Tank never empties. We can get a maximum of 16-17 gallons in it. The tank is 26 gal, and we previously have filled it with as much as 24+ gallons in one filling. The gauge needle barely touches F when full, and basically, the car is undrivable when it reaches 1/4.
Cavalier - Chevrolet :: 2003 Won't Shift To Park And Reverse / Stuck On Neutral And Drive
I have been driving a 2003 Chevrolet cavalier and the automatic shift is stuck and can only shift to neutral and drive since Thursday morning. It wont go up to reverse and parking and down to the other 3 shifts.
This first happened last April but somehow with the right grip or pressure was able to get back to all the other shifts. Since then it happened 2-3 times as I can remember and now could be getting worse.
Suburban :: 1996 Won't Shift Into 4 Wheel Drive
My '96 Suburban 1500 4x4 won't shift into 4 wheel drive. When I push the button for 4 Hi the light just flashes and stays in 2 wheel drive. The switch is good because I can hear it engage when I push the button. There seems to be a small amount of fluid (pinkish color) leaking from the transfer case but I couldn't get a good look at it tonight since it is about 10 degrees in my garage right now.

View 5 RepliesChevrolet - Suburban :: Dropping Out Of OD For A Split Second And Then Going Back In
I have a 1990 suburban that has had a rebuilt x-mission about 50,000 miles ago. At this time when I drive there is a hesitation, split second, when running on flat road. It happens when going up a hill, too.My mechanic said change the: plug wires, then the plugs and rotor. No difference.
I think the thing is dropping out of OD for a split second and then going back in. If I drive in 3rd, I don't think it is happening. Isn't there a relay or solenoid that controls this function?
Chevrolet - Suburban :: 2005 - Won't Start When Cold?
I have an '05 Suburban with starting issues. When it's cold out (below 40 degrees) and you turn the key, all accessories come on but truck will not crank. It then seems like the power just cuts off.......dash lights go out but gauges are fixed in place and a couple of seconds later, I hear a strange buzzing noise from the dash area behind the radio and the gauges will then go to power off position. Then if I try to start it, there is nothing, no lights on dash, no starter engaging, no clicking of the relays, nothing. I tried, on a hunch to disconnect the ground lead from the battery. Had it off for 10 minutes or so, put the cable back on, tightened it down (wasn't loose to begin with) and it started right up first try in 20 degree weather. I had previously had the battery and alt checked and both were good.
View 3 RepliesChevrolet - Suburban :: Flutter In Engine When Accelerate
2007 Chevy Suburban, 65K milesLet me start by saying I took this into to the dealer and they found nothing!
When I accelerate, I get a "flutter" in the engine. The best description of this flutter is that the RPMs go down about 200 or 300. I think it feels like it is sluggish when it accelerates. It is most obvious during the 35 - 60 MPH range, but you also see it when cruising at 70 MPH.
I tried adding some fuel treatment and ran some 93 octane through it to see if it was the fuel injectors, with no change in the behavior. No error messages or engine light is on. Regular oil changes and services (60K service, every 3K miles for oil change). Driving behavior has changed since I bought a Prius 3 months ago. It used to be driven 40 miles / day (+ long trips) and now is driven about 40 miles / week (+ long trips).
Chevrolet - Suburban :: 1995 - Stuck In 3rd Gear
1995 Chevy Suburban, currently at 150,000 miles, Prior owner had transmission rebuilt prior to 100,000 miles. While towing my 18ft camper trailer on a recent trip every time I started off from a stop I had to really push on the gas to get going. At first I though the emergency brake was on, or I had a flat tire. I then noticed the automatic transmission was not shifting when I had it in D. Checked the transmission fluid and it was full. The transmission seems to be stuck in 3rd gear. When I move the shifter to 2 it will shift down. Reverse is also still working. Am I in for a costly repair?
View 3 RepliesChevrolet - Suburban :: Random Power Drop Off?
I have random power drop off (best description is a loss then a surge or something like a skip) when driving over 60 mph. If I let off the gas or floor it the problem goes away temporarily. No mechanic has been able to figure it out. Chevy dealer just says "we don't have any codes".
View 10 RepliesChevrolet - Suburban :: 2002 - Engine Stalls At 75 Mph
2002, Chevy, Suburban 1500, 4wd, 5.3L engine, 210,000 miles. Mass airflow sensor and both O2 sensors replaced last year in an effort to fix this problem. Original problem surfaced when the vehicle was shut down or running uphill and had about 1/2 tank of gas in hot weather. If stopped, the vehicle would not start until it had cooled down. Sometimes getting it onto level ground would be enough to get it running again. ( This accomplished by turning on the key and allowing the vehicle to roll back out of the parking place. ) If running down the road, getting to level ground after the stall, pulling to the shoulder and cooling the engine/waiting a few minutes and restarting the vehicle would work. This was before the above mentioned repairs.
Last weekend in 60 degree weather I was driving back from northern Michigan and as I headed up hill at 75 mph with the tank at 1/2 the vehicle did a high speed stall on me. Symptoms were: RPM showed 2000, but pushing down on the gas actually dropped the RPM no matter how feather-footed I was. This was tried several times. I turned on the 4 ways and moved toward the shoulder and at 50 mph finally got the thing to restart. The rest of the trip home was uneventful.
I had a 2001 Suburban with the same specs which did this same thing until a factory recall that got me a new fuel pump. I asked about the recall the last time my truck was in for service and they said it does not fall within the serial numbers for that recall. Fuel filter replaced about 9 months ago. Co-incidentally but not necessarily related is that my battery with less than 3 years of a 7 year warranty was draining itself in less than 2 days this last winter.
Chevrolet - Suburban :: 2004 Not Able To Access Last 1/4 Tank Of Fuel
I have a 2004 suburban with approximately 125k miles on it, it is nominally my wife's car.
Recently it seems to not be able to access the last 1/4 tank of fuel. A couple of weeks ago my wife (who likes to run it down to the dregs) got it sub 1/4 tank, and it cranked but didn't start...put in 2 gallons from a can, started right up...took it to a gas station, filled it up (less the approximate 1/4 tank of fuel).
So, fuel pump? Pickup clogged? If so, what does it take to replace/repair...
Chevrolet - Suburban :: 1986 - Alternator Intermittent Overvoltage
86 Diesel Suburban
Lately the voltage gauge sometimes starts to wander upwards toward the 18v red zone. When it does it wanders up and down a lot, but mostly well above the center 13v. Sometimes I left of the throttle a little and it goes back and stays at normal, and sometimes it doesn't and bounces up again as soon as I press the throttle. Doesn't happen on every drive, just sometimes.
I thought it unlikely this was a bad voltage regulator, since it's a pretty new alternator, 2 years tops. So I thought I'd see what other possible causes could be. (Why do they make the voltage regulator internal to the alternator now anyways, since they seem to go bad more often than the core? Can I just add an external regulator like the older trucks had?)
I've heard over-voltage can ironically sometimes be caused by a short, since the regulator dumps more voltage into the field coils because the main coils are showing they aren't delivering enough current (because it's all being soaked up by the short), resulting in an overall over voltage as the alternator tries to compensate for the voltage drop of the short.
How do I tell if this is the cause of the overvoltage or if it's something else instead? If it is a short, where could it be? I'm assuming it must be somewhere weird, because almost any normal place I could think of for a short would simply blow a fuse. Or is there such a thing as a partial short-- high enough resistance to not blow a fuse, but low enough to drive the alternator nuts?
Could it be related to overheating? I initially thought that was a possibility, because it began around the time the weather turned warm here, but on any given day it seems pretty random and not tied strongly to excessive speed or going up hills.
Chevrolet - Suburban :: AC Refrigerant Level Is Too Low To Keep The Compressor From Engaging
2002 1500 4WD 126K miles. A/C not working, compressor does not engage when A/C is switched on. Is there an interlock if the refrigerant level is too low to keep the compressor from engaging? Original owner, A/C has never been recharged. Is recharging my best first step.
View 2 RepliesChevrolet - Suburban :: Intermittent Surge Or Shudder Between 40 - 60 Mph During Acceleration
I have a 99 Suburban with very high miles. Going on 306K mostly highway miles. This is our baby and the best vehicle I've ever owned. This is a solid vehicle that I think we can get more miles out of.
The problem is that it will intermittently surge or shudder between 40-60mph during acceleration. It's hard to pinpoint because it doesn't happen all the time. It seems to be worse if the vehicle is low on gas or the engine is cold but I'm not certain about that. It's not hard enough to call a buck, jerk, or sputter though. Maybe I've over-analyzing but basically it will shift to the correct gear and then back down then back up etc., and back and forth for very brief seconds. Then levels out after 60mph and there are no other problems. If the gas is low or engine is cold is does this in lower gears as well but usually only around 4th gear. I hope this description makes sense.
Here's where I'm confused. The transmission was rebuilt 2 weeks ago specifically the torque converter and rear planetaries. The day we got it back we performed a tune-up so all new plugs/wires/cap/rotor. The fuel filter was replaced about 8 months ago and the fuel pump 2 years ago. All regular maintenance has been performed on time since we bought it 4 years ago. Yesterday the Service Engine Soon light came on and it only showed one code (OBD II), PO161, so we replaced the 02 Sensor (Bank 2, Sensor 2).
However the problem persists and there are no other codes providing any direction. I've tried to search the internet for drivers with the same issue but the fixes vary too much and seem uncertain.
Other known issues for diagnostics: four wheel drive hasn't worked for years (haven't needed it in our flatlands) and ac compressor went out last spring.
Chevrolet - Suburban - Transmissions :: Occasional Shudder On Acceleration
I have an 82 GMC suburban with a 6.2 diesel, TH400 transmission and a NP265 transfercase. The last day of June we moved from Greeley Colorado to Southern South Dakota. Tems were as high as 107 that day. I had to stop several times to let the transmission cool. I didn't want to burn it out. I was towing a Hyundai Accent (2002) on a Uhaul Car Dolly. The trans temp gauge registered as high as 210 degrees. If it got hot I would stop and let it cool. However recently I changed the rear axle, the pinion spider gears seized and exploded. I think I went from a 3.73 gear to a 3.08. However I am not certain. Certainly seems like it when I pass people at 30 according to the speedometer that used to pass me. However, recently it seems to have developed an occasional shudder as I accelerate. It's mainly after alot of in town driving. I checked the brakes, serviced the rear end, and checked the fluid levels.
