Jeep - Grandcherokee :: Loud Howl When Accelerating
I own a rear-wheel-drive 1999 Jeep Grand Cherokee. I recently had both rear axle seals and bearings replaced. At the same time I had the mechanic check U-joints, shocks, etc. The noise from the failing bearings is gone, but now I have a loud "howl" that gets louder the more I accelerate. If I take my foot off the accelerator, the sound is gone. As soon as I accelerate, the sound returns. It is barely noticeable at speeds less than 35 mph, but the howl gets increasingly louder as the speed increases.
I returned to the mechanic the same day I picked up the Jeep. We went on a road test and I was given a story about gears in the differential and that despite the noise everything was mechanically sound. Even though the sound was not present before the seals and bearings were replaced, the mechanic assured me that nothing is wrong. This howling is giving me a headache!

View 1 RepliesJeep - Grandcherokee :: Loud Noise As Something Dragging Under The Car
Went over a bump on the highway the other day and heard a loud noice as if I was dragging something under the car. I checked but nothing was there. It reminded me of putting a baseball card in your spokes of your bike when you were a kid. It happened twice and the weird thing is that if I put it into reverse and drive about 10ft The problem went away. But something still seems loose and it sounds like it will happen again. I was googling this and it seems like the noise was around where the center differential or drive shaft?

Jeep - Grandcherokee :: 2006 - Loud Engine At 65 - 70 Mph / No Torque
I have an issue with my 2006 Jeep Grand Cherokee v8 Laredo that has been bothering me for a little over a year now. When the temperature gets warm out (over 80) and I am traveling on the interstate up a long hill (65-70 mph, towards the end of my commute so about 30 miles in or about 30 minutes) my engine randomly begins to sound like I am in the wrong gear (RPMs do not change but engine sounds like I just changed to second) and I loose quite a bit of torque. I can maintain my speed but my engine sound horrible. After about 10 minutes of this my engine goes back to normal and I can accelerate without issue. Then randomly it goes back to being loud with low torque. To add to the the fun, if this happens at any time during the day, the next day when I start my Jeep the issue resurfaces and I have no torque for about 10 minutes (5 miles) then all is well for the rest of my commute (40 miles downhill). I had a diagnostic scan done and they found nothing wrong and I also just got both of my exhaust manifolds replaces but the issue continues.
View 3 RepliesJeep - Grandcherokee :: Exhaust Getting Loud - Plastic / Chemical Smell In Cabin
I have an '08 Grand Cherokee Laredo, 3.7L V6 with 74,000 miles on it. Recently the exhaust/muffler have been getting loud, and during my state inspection the guy said it would probably need a new muffler/pipe in the next few months. That was about a month ago. Since then there has been an on-and-off horrible plastic/chemical smell in the cabin some of the time. My wife drives it about an hour to work each way, and she says sometimes it gets so bad she has to open the windows (in 20 degree temps....) or she gets a headache. She describes it as a "formaldehyde smell" and says it tastes kind of sweet. To me it's more like a burnt plastic/chemical type odor. I checked all underneath but saw no plastic bags or anything else odd. Nothing unusual under the hood. No visible smoke. I have an appointment in two days to have the exhaust fixed. My question is - is there any way this weird smell could be exhaust related? I am hoping so, because otherwise it's a total mystery. It's definitely not an "exhaust" smell as I know it.

I have a 1999 Jeep Grand Cherokee Laredo. Some of the gears are intermittently "sticking". When I get up to 60 m.p.h., it's supposed to shift into the next gear, but sometimes it won't and the vehicle starts lurching as it comes up against the "shifting wall". Other times it won't downshift, so I leave a stop light in 2nd or 3rd gear. The lurching only occurs for the gear at about 60 m.p.h., unless I put the gear selector into "2", then it sometimes lurches there too. Several mechanics, including a transmission specialist at a local Jeep dealership (who charged me for 2 hours of "diagnostic time"), couldn't determine what is wrong. I did a transmission fluid flush, but that didn't work.

View 2 RepliesJeep - Grandcherokee :: 1999 - Stalls And All The Lights In Dash Go Off
I bought my jeep about a year ago, and have had major problems with the computer system. My car wouldn't start for days on end, and then one day would start right up. I just went ahead and replaced the whole computer, wiring, ect..and it ran fine for about 4-5 months. Once and a while the check engine light would come on, but nothing happened. Then one day my car died right in the middle of the street when I was driving it. All the lights in the dash go off and it just stalls.
Sometimes it starts back up immediately,and others I have to sit for a god 15 minutes. Sometime it'll do this 5-6 times in a day, others it won't do it at all. I noticed it does it more often when it's hotter outside. I got the check engine light checked (it comes on only once in a while) and the code said it was a cylinder 6 misfire. I took it into the shop and the checked my spark plugs and said they were fine, and they couldn't find anything. Could this be related to the new computer? What I should have checked on it?
Jeep - Grandcherokee :: 1999 V8 - Top End Noise And Dead Cylinder
It was running on 7 cylinders and had not been tuned in probably 50,000 miles or more. I recently bought it at auction. Changed spark plugs and 1 coil for the dead cylinder. Rear cylinder on passenger side was not firing. Compression test shows 150 psi that cylinder. Fairly loud mechanical pecking from that area which was isolated with a stethoscope. I suspect a flat cam lobe or broken rocker arm.

View 2 RepliesJeep - Grandcherokee :: 1999 - Power Cuts Out When Driving?
1999 Jeep Grand Cherokee Laredo, 4.0 in line 6 Cyl misfires when driving. I bought this about 2 months ago (200,000 miles), and when i first got it it was acting like it was misfiring when driving above 60 mph( did get codes P0301 cyl 1 misfire, and P1391 CPS) . it started to act the same way just driving in my small town. so i ended up changing the ignition coil pack and changing spark plugs, i also replaced the CPS (camshaft position sensor). and was still acting the same way. I located a TSB that said there might be a carbon build up problem preventing valves from rotating and seating.
So I used seafoam and clean up the Top, and drove it in low gear at 4500 rpm for 15 seconds or so 6 times.. initially when doing this it was cutting out (jerking) when rpms got up there. after doing this twice with about 3 weeks in between never had a problem in town with it acting up running like it should from what i can tell..
Then i took a road trip, and a 60 mph was fine, 70 mph it was fine.. so i thought it fixed the issue and all good.. but about an hour into the drive it started acting up again.. unexpectedly cutting out for a second here and there, and usually when going up hill, and when got to destination about another 40 minutes, coming to a stop light i noticed it when stopping it was running pretty rough like it wanted to die out but never actually did. never got any more check engine lights either. I'm kinda at a loss at what the issue might be, and what i need to do to fix it as i really like the vehicle
Jeep - Grandcherokee :: 1999 - Heater Broken / Fan Only Blow Cold Air
My 99 grand cherokee's heater is broken - fan blows but only cold air. I've had two mechanics tell me its probably the blend doors and will be quite expensive to repair because it requires removal of dashboard. Looking for after market repair kit which allows for a DIY fix going through the glove box? Is this a good bet to try?
View 5 RepliesJeep - Grandcherokee :: 1999 - Knocking Noise On Wheel Area?
I have a 1999 Jeep Grand Cherokee that, upon starting in the morning, has a knocking noise coming from the front passenger-side wheel area. It only knocks when the car starts moving, and stops once I get up to 15-20 miles per hour. It ONLY does this when the car is cold. The noise does not occur throughout the day, only when I start it each morning. Is it something to do with the wheel bearing, but that does not seem to be the case.???

My 99 jeep grand Cherokee 4.7 v8 4x4 will not start after 2 to 3 short trips. it starts up fine in the morning when the engine is cold but driving for a while while and I stop somewhere and shut the engine down for a few minutes it will not restart.. after I wait 10 to 15 min it start up ok.. Next when I'm driving on the highway, after 10-20 mins of driving, the engine stalls for 5-10 secs. and fires back up..I inspected all connections and the starter which were ok but I did find that the starter is soaked with oil dripping from the valve covers.. Could the oil be the problem..? Even causing the stalling out on the highway..?

When I fill my tank with gas I get a very strong odor of gas throughout the vehicle, what do I need to check to fix this?
Also this one is weird, but everytime I make left turns ONLY, my Jeep does a down shift but stays in Neutral longer than it should but then kicks into gear by me taking my foot off the gas pedal and reapplying. What this could be? I have made sure that my Transmission levels were fine but I am baffled what the problem is?
Ford F-150 (2004-2008) :: Loud Rear End Howl / Whine
My '04 4wd has a pretty loud rear end howl, it is a LS but don't think it's an LS problem, no noises or chattering when turning. Howling is loudest at 50 to 60, but some noise at all speeds. I don't mind tearing into the rear myself, but not sure if I could tell what was wrong just by looking, i suppose bad bearing might be obvious, but not sure how to diagnose gear lash tolerances. It only has 107000 mi. and is an 8.8 rear I believe.
View 2 RepliesJeep - Grandcherokee :: Loss Of Oil Pressure
I have a problem with my jeep grand Cherokee Laredo 5.2v8 losing oil pressure when the engine reaches normal operating temperature. the jeep sat for 2 years but we got it to run. when normal engine temperature occurs, the engine drops oil pressure and stalls. I have changed fuel pump,oil pump and oil pan gasket. also ran a cleaner through the engine. it doesn't matter if its winter or summer. the only way I can keep it running is to keep my foot on the gas pedal. if I don't do this the jeep stalls. a mechanic said it was the bearings. I don't believe this because there is no knocking noise when the engine is running. it has 103663 miles on it. it has just city and highway miles on it. never has been off road.
