1995 LeSabre Custom Right Turn Vibration (Read In)

Thanks to all who read this thread. Thought I'd ask those who may have experienced front end noise. The car will make a vibration that seems to have no real source. When driving in the left lane it is real quite...the right lane it groaning (due to the grading for water run off). My first thoughts was another wheel bearing. One lane might side load the bad bearing in such a way to cause noise. Also...when turning right at speed (off ramp) it is "Very" loud.

To date...I have done nothing to fix the noise. My geusses are...

Bad passenger front side bearing...right was replaced 20K ago
Tie rod ends inner/outer (car only has 50k miles...doesn't seem likely)
C/V shafts (no rips tears...seem quite at lower speeds...not likely)


Could there also be transaxle mounts that would transmit noise due to metal to metal contact?

It does sound like a wheel bearing. If you slightly turn the steering wheel a bit while driving in the left lane, does the noise change?

Next test: jack up the car. Put it on jack stands. Grab the top and bottom of the tire and feel for play in the bearing. You should't feel any slack.

^I Agree^

Looks like the weather will be above freezing this weekend.....so I'll do a wheel bearing on the front. This is the third time on two different cars where a bearing has failed. Each time they go a little different. The first time was a rear on a 1988 Old's 98. It made a "thrumming" noise and was loose at inspection. The second was on this Buick on the drivers front side...the sound it made was a "metal screeching" and was easy to diagnose. This one gets me...I'll bet I will find some slop...maybe not much. What I was more worried about was something in the trans-axle. I'll go from here and I'll post what ever was wrong at a later date.

Looks like the problem was the passenger side bearing assembly. Also it solved the erratic signal from the wheel sensor (ABS). I also did 2 new rotors and pads for the front end. I'm really enjoying the smooth ride I was used to before...and didn't spend money on anything I didn't need to.

Great to hear! I don't like spending money on thing I don't need either. Especially if it didn't fix/change any thing on the vehical.

Glad to help.
