Grand prix has speed related rumble. Seems to come from RF wheel. Wheel bearing feels tight. LF front is barely loose. Car has 150k miles. Should I trust my ear and change RF? Car is quiet at 30mph. Seems to make noise at 40mph+
View 6 RepliesThe front driver's side wheel of my 2007 Ext. Cab makes a speed-related "ticking" sound. It's usually audible but not always there. I look for rocks in the tread of my BFG All-Terrains and sometimes I find some, sometimes not. The noise seems to be independent although some of the rocks really get up in there. Sometimes its really loud and it sounds like a rock. Bearing? 4WD CV or U-Joints or whatever?

Issue : Usually after driving the car for a long period of time (approx 20 miles or more), Ill begin to hear a grinding coming from the front of the car. The grinding/ groaning can be felt in the gas pedal as well. Depending how hard I hit the gas the frequency increases. I am not sure if this is associated with the grinding, but i noticed that when I turn sharply and go easy on the gas and progressively add pressure the car will cut out until i cut straighten the wheel. Then all the power I requested is applied all at once.
What the locals think :
CV Shafts - Sears told me the first time i went to get them checked that my CV shaft boot was a little loose, suggested changing it. Then I went back two weeks later and they denied saying that and said my cv shafts were fine. (talk about confusing)
Wheel Bearings - Someone I know said my wheel bearing could be slipping or my traction control could be on its way out, so i replaced both front bearings.
Tune up - Someone suggested it could be mis-firing, with it coming up on 100,000 miles, i did a tune up. (plugs, wires, coil packs)
Transmission - Someone said the transmission could be going bad. So i did a flush and inspected the fluid, no shavings or any sign of extreme wear. (car shifts great too.)
Clogged Catalytic converter - the cat was clogged, two new 02 sensors and a new cat didn't even solve the issue I am describing, but it does have more power now.
Throttle Body - Someone said it could be a dirty throttle body....so i had that cleaned also.
And finally, some electric temperature sensor - someone said it wasn't getting the right fuel mixture, so i replaced the sensor to remedy that.
Fuel pressure was also tested to ensure the fuel pump was doing its job, everything checked out great
When coming to a full stop, there is a growling/grinding sound from beneath the floor behind the brake pedal and I can feel the growling./grinding in the pedal as well. Used to happen occasionally, now is happening more often than not. When the Service ABS System/Service Traction System message is displayed (occasionally) on the message center, the growling/grinding doesn't occur and the brakes work. Like normal. When I turn the car off and restart it, the messages are no longer displayed and the growling/grinding sound and feel returns.

View 3 RepliesI'm getting a little rumble in my Lt Rear wheel bearing with just over 50k miles. I'm looking online at parts and the part number for the hub/bearing assy is 4246033030. It's showing up as a Toyota part as well.
Does the same part matches a Camry or Avalon? The Toyota version of the part is about half of the price.
My wife's Explorer 4x4 has a noise in the front at around 100km/h. It is not detectable below 90km/h. Its not noticeable from a standstill until around 100, then you hear it a little. I find I can make it more noticeable if I vary my speed from 110 to 105 up and down, then its easier to hear. Once you get below 90 km/h you cant hear it at all.
I have a broken leg right now, and I normally do ALL my own work so I'm a little-limited mobility wise at the moment.
I'm suspecting a wheel bearing. I put the Explorer in the garage and my son jack up both wheels on the drivers side. I started the engine and SLOWLY accelerated up through the gears to 100. I know the hazards with this as I've done it with other vehicles, but this was the first 4x4. Then we jacked up the passenger side (after lowering the drivers side) and did the same thing. I could slightly hear/feel the rumble when the passenger side was jacked up.
I did drive the vehicle on my outdoor ramp/pit so I could use my crutches and get underneath to have a look. I grabbed the cv axles and they feel solid. The propeller shaft was replaced last year, and the cv axles look brand new. (bought the vehicle off a friend two years ago.).
So, are my suspicions correct, is it the pass. side wheel bearing? The Explorer has 294000kms. Never did test it on corners as I didn't want to swerve back and forth on the highway with the amount of traffic.
I have a 2002 toyota echo and about 2 months ago my front left wheel came off while driving and ever since it has been making a thumping noise that is related to the wheel speed. I have replaced the front struts and brakes but the noise is still there. There is also a whirring noise. I have ruled out wheel bearings, ball joints and tie rods. I noticed vertical play in the right cv axle. It moves up and down coming from the trans and not the knuckle. Could that be the noise?
View 1 RepliesMy dealership said our left rear is noisy and that we need new wheel bearings and a speed sensor and to do an alignment and balance. I called my other wheel place and they are about $300 cheaper. But, they said I have the option of an OEM wheel bearing or different one. I'm a little confused, but I think the OEM would be about $85 more, if I understood correctly. Whether or not to get OEM for this?
View 19 RepliesI've been feeling more and more, a vibration in the RX400 AWD. Just to be certain, I had the tires rotated and balanced....still there. My conclusion is a wheel bearing.
What I notice, from 60 up to 80 MPH (speed limit in WY & MT), a slight vibration in the car. I can't pinpoint if it's front or rear, but there is certainly one occurring.
So, is there anything else that could contribute to this or is it usually a wheel bearing going bad? I just drove 1200 miles over the holiday and didn't notice much of a change. Still vibration. Not so strong that my wife has noticed, but enough that I'm feeling it.
I assume it's just a complete assembly and can be changed out relatively easily. I've done my 4wd suburban so I'm guessing similar in work.
How to test which assembly is going bad? Front/Back....Left/Right?
Need to replace at least one rear wheel bearing, but still not positive which side. Getting a whump whump whump and slight howl at speed that seems to be worse going around right turns, so will change the drivers side first.
View 3 RepliesI have a Mk6 GTI 2010 and recently there has been some noise coming from the rear of the car and the noise changes with speed and sounds similar to a wheel bearing.. So I jacked up the rear and found that there was play in the passenger rear wheel.. The bolt holding the hub together was tight..
View 2 RepliesI have an 01 Ranger 4x4 that recently started to make a loud speed dependent noise from the drivers side front wheel, a quick jab to the right on the steering wheel and it stops, straiten out and it comes back...since I know my shocks are worn and have some cupping on the front tires my first thought was tire noise so I moved the back tire which is evenly worn to the front and no change, next I removed the tire and checked everything visually.
All seems ok, the brake does not seem to be dragging and there is no evidence of a cv problem, everything seems tight, so I'm guessing the problem is a bad wheel bearing? If I grab the tire at 12 and 6 there seems to be excessive movement from top to bottom, there should be none right? If memory serves any movement is indicative of bad wheel bearings? I guess I'm looking for some vindication before getting a new hub?
I have a rear wheel bearing type of noise that appears to come from the rear. My vehicle is front wheel drive and has 135K miles.
I checked the rear wheel bearing/hub assys on both sides and they had no play but I changed them anyway. Noise did not change at all. Rear tires have normal wear, no cupping or anything. Noise gets louder with increasing speed up to a point and then remains a constant level.
My next thought is to check the front wheel bearings/cv joints.
Engine starts then runs for a period of time until it warms up, then fans come on and then EGR clicks on and off every other second , then it eventually quits. Replaced the coolant temp sensor. And it never sets a code. Have checked wiring for shorts and nothing. Is it a ECM going bad?? When trying to drive it , it will only go about a half a block , then quits , Then will start up again.???

I just got new struts, brakes, rotors etc on my 95 grand prix. A few weeks later my ABS light went on.... Do I have to get it fixed right away?
View 11 RepliesI got my car from an auction and I apparently had to do work to it and we got most problems fixed but now when i saw my fuse box i saw their wasn't a fuse in the radio so i put on in there and it can on so I thought cool it works so i turned my car off and the radio stayed on and i thought, bad fuse so i got a new fuse put it in and my car was still off and the radio stayed on. So i can't have a radio because my battery will drain. The ignition works i got a new one installed it perfectly my car is a 2000 Pontiac grandprix gtp supercharged. I've only had it for about 3 weeks ...

View 2 RepliesHottest day ever on Planet Earth and my air conditioner in my Pontiac decides to throw hot air in my face! Luckily, for my female companion, she gets ice cold air. This 2002 Grand Prix 40th Anniversary edition has 236,000 miles, I never once had a problem with the air conditioner in the past (have thought about contacting GM asking what they did right in this car)This model has dual climate control. I noticed that in turning the selector knob on the dash climate control panel, there is hot air in the vent, bi-level, heater and defrost, but cold air comes out on the passenger side. The interior temperature functions are all similar on the '97 through '03 models of Grand Prix, just wondered if this is something I can fix, or do I need to visit a Pontiac dealer to have it diagnosed (and spend a lot of money)
View 3 RepliesCode is for tcc stuck on. Code p0741 is tcc stuck off. So, it's a sticky solenoid. Which means it may start out sticking occasionally and progress to sticking more often and finally staying on/off permanently? If u get the code/symptoms 1 time, does it usually mean it will happen again, soon?
View 1 RepliesMy 2001 Pontiac Grand Prix 3.8 L V6 with120,000 miles shakes/vibrates when I accelerate while turning/veering right (as when coming out of an exit to merge into oncoming traffic). It does not vibrate when I turn left. I have new balanced tires, replaced both front tie-rod ends, and the rack and pinion by a certified GMC mechanic. What could be the problem?
