Hello all,
I've been trying to diagnose the poor ride quality of my 2003 530i Sport. Basically the car seems overly sensitive to imperfections in the road. Even driving on brand new pavement there is always a shakiness to the ride quality I can't seem to get rid of. I've owned two other BMWs (both Sport models) and both were glassy smooth when the road was smooth. I understand the Sport Package will give more feedback, but this is more an annoying than my 330i Sport was. Here's what I've replaced/done:
- New Pirelli PZero M+S tires (balanced 4 times, including road force)
- All suspension parts with bushings or ball joints are either new or I checked them and they are tight (swaybar links, thrust arms, control arms, front and rear, all checked out and replaced).
- New sport shocks with new shock/strut mounts front and rear.
The car takes bigger bumps (expansion joints, potholes, etc) as I would expect, but it's the constant sensation of driving on a rough road even when it's smooth that's the problem.
What I'm looking for are any other E39 (preferably Sport) owners who would be willing to let me take a drive in their car (and drive mine) to compare. Also, perhaps swap wheels so I can rule those out or perhaps look for a new set of tires. I'm sick throwing money at parts trying to chase down this problem and any help would be appreciated. Please contact me by email at: drevilkep at hotmail dot com if you can help out (or just post back here). Thanks everyone!
EDIT: I'll be happy to provide beer to anyone who can help me track this one down!
