Pontiac - Montana :: Loud Clunking Noises From 2005 Minivan SV6

I have a Pontiac Montana minivan SV6 that is making strange clunking noises from possibly the rear or middle of the van when I go over a bump, large or small. I have had it in to our local mechanic and the local tire/repair shop and transmission shop. They have not been able to locate a problem other than agreeing that there is a noise.

Our mechanic replaced the front struts and strut mounts, the rear shocks and has gone over the entire suspension and transmission more than once. The noise is very loud, like something is broken but despite three separate shops checking it out nothing can be found.

Any possibility is could be something with the automatic side doors, such as the motor being loose or something strange like that? If it didn't have this clunking sound the ride would be very smooth and quiet. It doesn't affect the ride at all. The other bit of info here is that we haven't owned this van for very long, we bought it as is thinking that it needed shocks or struts. They've been replaced but the sound is still around!

Pontiac - G6 :: 2007 - Steering Stick While Turning Sharply At Slow Speed?

2007 G6 Problem occurs at slow speed with sharp turning, such as coming out or into the driveway. As the steering rack moves slowly it tends to stick and release 3 or 4 times when turning sharply at very slow speed. It makes a sound so loud even the passenger cam hear it and the driver can feel it in the steering wheel. Does occur while driving normally. The dealer says its a GM problem with no real correction. They greased the rack and said the problem would return soon, but it is not a safety problem. So far they have been right on both counts. Are there any real cures?

Elantra XD (2001-06) :: 2002 GLS Making Clunking And Whining Noises At Certain Speeds

I recently had my manual transmission go out on my 2002 Elantra GLS. It has 208k miles and the tranny had been giving me shifting issues for years. It finally made some clunking and whining noises at certain speeds. I picked up a replacement tranny, but the car has sat in my garage for the last two months. I slowly worked on it over that time and have finally completed it. I went to start it up tonight and it idles normally for 1 second, then it revs up to about 5k. It does this over and over until I turn the car off, and a very hard to see white-ish smoke comes from the air intake tube as I have it only partially on for testing.

The car ran fine before hand. What could this be? I have never experienced this with a vehicle before and searching on the web only gives me links to people having idling and revving issues while at stop lights or on the freeway. The idle did used to stick around 2.5k RPM when I started it up from time to time. Although, a small blip of the throttle would set it back to its normal idle speeds. BTW, the engine runs well with no knocks and has great compression across all 4 cylinders.

Pontiac - Torrent :: 2008 FWD - Clanking Noise When Turned Wheel Sharply Almost Like Gears Slipping

For a little while I have been noticing an odd noise from the front driver side tire. About a year ago on two different occasions I heard a sound when I turned the wheel somewhat sharply that sounded like a clacking noise almost like gears slipping. It only happened for a few seconds and stopped but has never done it other than those 2 times that I am aware of. This is my wifes everyday driver, so I don't always hear the noises.

Recently it started making a sound that to me sounded very similar to a wheel bearing going bad. I looked into it a little and drove it and decided to change it even though it didn't have all the "symptoms" of a wheel bearing (louder when turning away from that side, quieter when turning towards that side, play in the wheel). After replacing the hub assembly it didnt make the same noise, but made a different noise that was from the shield on the back side of the rotor rubbing against it. Took it for a drive thinking that I fixed it only to have it start doing it again. After listening closer it sounded like a metal rubbing against metal sound, sorta like a brake pad dragging on a grooved or rusty rotor. I inspected the rotor and all i saw as an issue was on the inner side of it there was a ring of rust on the inner and outer edges, and it was wearing the pad to have beveled edges. I replace the pads and rotor, and it still makes the sound.

I am down to two options that I can think of trying but do not want to really try either one because of the amount of money I have already put into it.

1) I have thought about replacing the brake caliper.
2) I have thought about replacing the CV Axle, BUT the boots are in excellent shape.

It doesn't make the noise all the time, and sometimes it is worse when turning to the right, and other times there is no change regardless of the direction you turn. When it does do it, it feels almost as if the car is dragging and pulls to the drivers side.

I am really at a loss here and don't want to keep narrowing it down because I have misdiagnosed the problem twice now, and was really confident in it being the wheel bearing.

Chevrolet - Beretta :: Brakes Don't Work While Sharply Turning

My brakes work well enough while going straight. However, when I am sharply turning the car and braking at the same time (like when I'm pulling into a parking space), the brakes don't work.

This is potentially dangerous for the pedestrians/other cars near me when I'm parking (but no accidents yet). A quick brake check by my mechanic while the car was in for something else showed nothing out of the ordinary in there. It's a 1995 Chevy Beretta.

Questions: What is causing it? How is it fixed? Is this something that a tinkering amateur can do, or should I go to a professional.

Montana :: 06 - Steering Looses Power At Low RPM And Starts Making Whistling Noises

I have a 2006 pontiac montana sv6 AWD

Once everything warms up the steering looses power at low rpm and starts making whistling noises around the steering wheel and can also be herd outside the car somewhere.

I have just replaced the power steering pump and flushed the system. I also replaced the belt and tensioner at the same time.

Air has been bled from the system and i have checked everywhere for leaks and cant see any and I am not loosing any fluids. But I still have a lack of power and the whistle noise sounds like it is sucking air into the system somewhere..

I still get some small bubbles coming up in the reservoir even tho i have bled the system soo many times now.. What is going on?

Montana :: 2000 Pontiac Squeaking When Accelerate

My 2000 Pontiac Montana squeaks while accelerating. There is about 55,000 miles on it. At first I thought it was a belt but it would squeak the whole time if so. It only squeaks (like a mouse), every time accelerating.

Pontiac - Montana :: 2001 - Overheating / Low On Coolant

I have a 2001 Pontiac Montana that was overheating. It was low on coolant, and using coolant. I took it to a mechanic who checked it out and found exhaust gases in the coolant. He initially told me that it was a bad head gasket. After doing a bit of research, I am told that it could also be an intake manifold gasket. I know I am losing coolant, but I cannot tell where. I don't think it is going into the oil, as my oil level does not go up. I do not see coolant leaking below the vehicle, so perhaps it is going into the exhaust? Or leaking slowly on top of the engine where it is burned off before it can go on the ground.

Is there any test I can do to determine which gasket is bad before tearing into the vehicle? I thought about sending an oil sample off to determine if I am getting any coolant in the oil, but I don't know if that would be useful information at this point.

Malibu :: 2005 - Intermittent Low Pitch Whistle Noise When Turning Sharply On Right Turns

2005 Malibu LS 3.5L (Epsilon Body) with rear disk brakes. Do the rear disk brake pads have the wear indicators just like the front pads?

Car started making an intermittent low pitch whistle noise (sounds like an old steam locomotive whistle, just really low muffled) but it only does it while turning sharply on right turns. It doesn't come on while turning left or driving straight.

At first I suspected the fuel pump but I'm not sure. I've owned the car since 2008 and never replaced the rear brakes, so it might be time!

Montana :: How To Remove Vents Above The Radio On 2006 Pontiac

The passenger air bag indicator light got pushed in so I need to get the vent panel off so I can push the light back flush. I do know the surrounding of the radio pops off without any tools. But taking that off doesn't get me anywhere. I still don't see access to remove the vents.

My van will rev really high when started and may stay that way for most of the day. Sometimes once it is turned off it will restart just fine. but when it is revving like this you have to hold the break down at stop lights, constantly slow down because it wants to take off. Now it is stalling when driving slowly. the throttle positioning censor has been replace a couple of times.

Pontiac - Montana :: 2001 - Engine Drops In Power When Hit 30 Mph

I have a 2001 Pontiac Montana van, when i drive i feel like there is just not enough power there. Most of the time when i hit 30mph the engine drops in power, hard to explain so I will try my best. I get in turn the key starts right up with out any hesitation what's so ever! I leave for work, while driving when I come to a stop sign and stop and take off its gets sluggish so while my speedometer is going up my movement is not changing as it should so needless to say I have to do 80 85 mph just to keep up with the average moving can at 70mph.

Once in a while I will give it some gas and let go of it and it would back fire a little not sure why. Recently I had new head gaskets put on cause temperature was not staying where it was suppose to be, they smooth out the headers and did a tune up, not sure about the timing, New fluids, once in awhile the temp would climb but that cause of the fans. Took it to AutoZone they did a obd code check came back with O2 senser and nothing else, so if I replace this will it bring my van back to normal running operation? And would it be anything I could check to rule out?

Pontiac - Montana :: 2006 - Check Gas Cap / Code P0455

I have a 2006 Pontiac Montana SV6 with 80,000 miles on it. Recently the dashboard warning "check gas cap" has started coming on. I have replaced the gas cap and cleared the code and it is doing it again. It seems like it is more likely to do it when the gas tank is 1/2 or less full but it also did it today with almost a full tank. The code from the computer said P0455, what this could be?
