I have a 2005 LX Sedan. I recently replaced the wheel bearing of the driver's side front wheel. When I bought the car, the front bumper and underbody panels were damaged from the previous owner having run over a tire or something. After I had the car for a year, it developed a growling noise and it turned out to be a bad bearing.

Anyway, since I've replaced it, it's been so quiet but my car has developed a new issue. Whenever I'm going in the range of 40 - 80mph and let go of the gas, I get this rhythmic noise and a bit of vibration that I can sense through the pedals.... especially the brake pedals. It has a similar tone as a tire hitting the road because it's off balance. Could an unbalanced CV axle make such a noise and vibration?

Not always but occasionally, I get a slight shimmy of the steering wheel while braking in this speed range. But it's so intermittent that I wouldn't say it's rotors warping or even out of balance wheels.

Any ideas? I tried to record the sound but it doesn't get picked up on a phone (usually only get wind noise).

 

When I am driving anywhere over 40mph and I completely let off the gas pedal...I get this really loud rumbling noise and it shakes the jeep pretty good. More of a vibration shake...not like a death wobble shake. But as soon as I ever so gently touch the gas pedal...it goes away. It sounds like a wicked tire noise. I get the same noise when I come to a slow stop such as in a parking lot of something...it just sounds like 33's with bad tread coming to a stop, but I never had it happen at highway speeds before. It's just real wierd that it goes away when I'm giving it throttle.

Move the front tires to the rear and see if the same keeps happening, but I'm willing to bet you have a tire balance/wear issue or a sticking caliper.

 

Finally got the time to examine my car again (with other issues, unrelated). Anyway, I looked at every suspension component with no luck. One thing I never tried was perform the wheel wiggle for detecting a bad wheel bearing. I just replaced it so I NEVER thought to check that.

Well, the same wheel where I replaced the bearing shakes ever so slightly and makes the small clunk/click noise when I rock it at 9-3 and 12-6 o'clock positions. WHAT?!?!?!? I just replaced them!!!

My only guess is that I may have accidentally pushed against the inner ring when I pressed in the bearing. I used one of those manual wheel bearing press kits. it was my first time using it so I wouldn't be surprised if I goofed on one of the steps. Has anyone experienced something similar?
