Default Vibration issues

When I pick up my car I feel this vibration coming from my wheels. It only happens around the first and second gears. Once the car is fast there is no more issue. It also doesn't happen when I pick the car up slowly. If I go even a bit fast I hear this rotating like noise and vibration. Any ideas on what it could be?

Bad wheel bearing perhaps?

i am a wheel bearing specialist at this point after figuring out my bearing issues for weeks on my own. Had to replace both front =/ $1500 with discount at lexus.

There are a lot of factors that are needed to make it a wheel bearing issue. Simply a vibration won't mean it. Fastest form of notification on a "failing" bearing would be a light whine pitch/whistle. NOT the loud howl as most people say. You will hear that once your bearings completely fail and seize.

please describe more in detail of your issue so we can help. vibration can be caused from anything

preliminary thoughts: if you only get it in 1st/2nd gear (which speeds btw, or just gear related) it sounds like your tranny/engine mounts are weak..

i've had this type of issue with 2001 acura TL. It was positively the mounts. the rear and side mount were gone and i had a jump/fast rhythmic vibration at 1/2 gear



Ive heard of some faulty engine mounts for this car (correct me if im wrong) and I think its the case as I also have a bad engine mount currently on my 2007 SWB with 80K. It has vibration from mount failure but no jump. I think its dependent on which mount fails (i think a side one will cause that issue as it causes one side of car to be much lighter for a split second, wheel hops up and loses grip.

We actually just changed the wheel bearings about a year ago if even that. Im going to try to get the noise on video to hopefully make the issue clearer.

why did you change your wheel bearing. Just one or two?

I would still suggest it being a mount issue.

I forgot to mention I have a weakened engine or tranny mount as well. Looking at polyurethane fills.
