The 1st thing i think of..

you need a 4 wheel alignment.

if your wheels are all out of whack..when you hit those rough patches, your car will be all over the place.

have it checked out

hope this helps

let me know

One high beam not working 2006 Buick lacrosse


Sampson, sounds like a bunt out bulb, which will need changed.
If you feel comfortable doing it yourself. Basically three screws, and you have to pull one plastic fastener from the fascia (bumper) and pull the bumper back a bit, and pull the assembly out. I believe it is in the manual, not bad to do. I will post a link to tell or show you how to do it. Press the helpful button

this might help:
Here is the Technical Service Bulletin that maybe of help, worth looking into but can't guarantee that it would fix your problem Steering - Steering Column Clunking When Turning TECHNICAL Bulletin No.: 01-02-32-001P Date: November 25, 2009 Subject: Clunk Felt/Noise Heard From Steering Column, Steering Gear and/or Front Of Vehicle During Turning Maneuver and/or Steering Wheel Rotation (Replace Intermediate Shaft As Directed) Models: 2001-2004 Buick Regal 2005-2008 Buick Allure (Canada Only), LaCrosse 2000-2008 Chevrolet Impala 2000-2007 Chevrolet Monte Carlo 1998-2002 Oldsmobile Intrigue 2004-2007 Pontiac Grand Prix Supercede: This bulletin is being revised to add the 2008 Buick LaCrosse/Allure. Please discard Corporate Bulletin Number 01-02-32-001O (Section 02 - Steering). Condition Some customers may comment on a clunk type noise coming from the front of the vehicle while driving during a turning maneuver.

1. Locate a large area (parking lot) where the vehicle can be turned in a tight circle. 2. Turn the steering wheel to the right and/or left all the way to the steering lock, then off the steering lock a 1/4 turn. 3. Drive the vehicle approximately 5 km/h (3 mph) in a circle, preferably over rough pavement or seams on the road surface. 4. Drive the vehicle straight ahead at idle speed while applying and releasing the brake pedal. Listen/feel the steering wheel for the clunk/noise condition. 5. If a clunk is felt in the steering wheel, the MOST likely cause is the I-shaft - not the steering gear. Continue with the correction. Correction DO THIS - Replace the intermediate shaft DON'T DO THIS - DO NOT lube the intermediate shaft Replace the existing intermediate shaft

The left rear wheel on my 2005 Buick Lacrosse is not parallel to the right rear wheel. I would greatly appreciate any suggestions about this problem. Thank you in advance for having read my message!


Hi Michael, make sure the vehicle has not been involved in an accident. If the vehicle is sound have the suspension bushes inspected and the rear mountings checked. If there is a drumming noise from the rear it will most likely be from worn bushings. Regards John
