RESOLVED - Steering Chatter/Front Suspension Issues

[RElias21]

For a couple months now, I've been getting steering wheel chatter/vibration whenever I load up my front, passenger side.

For example, if I'm making a left turn at speed, it almost feels like I'm driving on ripples. I get a lot of steering wheel chatter feedback.

It also happens if I brake hard, but I want to emphasize that it's not JUST on braking, so I don't think it's a brakes issue.

It only happens when I load up my front passenger side, not front driver side.

I'm riding on MP-HAS and OE shocks.

I don't have any reason to believe that my wheels are bent and the car cruises fine.

Also, I work from home and drive around town most of the week. This issue is not really noticeable around town. It starts to become more pronounced at higher speed cornering/braking.

Any thoughts on troubleshooting?

Maybe check the tension strut for leaks or play. I know they are a common failure in the f30 and look like pretty much the same part on the f80

Following up on my issue here, to maybe help locate the problem, here are a few developments:

(1) I changed back to my 513s and the same issue persists, so I’ve pretty much ruled out any wheel/tire issue;
(2) I feel that the issue is getting worse…i.e., literally feel like my front passenger wheel is bouncing whenever I brake even at lower speeds now and anytime I hit a pothole on that side;
(3) it’s def isolated to the front passenger side, as the front passenger wheel shutters/blunces bounces whenever that sides goes over a pothole or undulation.

This is pretty prominent. Passenger can feel it too.

I feel like this sounds like a blown shock, but I don’t see any oil on the shock?

Thoughts?

Initially I thought I had a bad bearing. After removing everything tk get ready to replace the bearing I noticed this:

Looks like it’s the lower control arm.

Ordered a new control arm and replaced today. Looks to have resolved the issue
