:rollsmile: Funny you should mention that, had a worn out boot lock causing a shock type knock on an E30. Have a look, who knows? :fencelook:

I have developed this problem in the last few days, only notice on uneven road surfaces... not shock mountings... well at least they look ok.

So interested to hear moooaaaarrrr thoughts?!? I want to do track day on Saturday (My Birthday :joy but don't feel like a collapsing shock going around lets say... turn 4...n:thumbdo:

:rollsmile: Or diff jumping out on the straight! Seriously, though, I understand your concerns. Do you have a set of axle stands? Best to pick it up, take a crow bar and pull/push things around, roadworthy test style, see what moves. Is the exhaust definitely out of the question? :fencelook:

Thanks Bud. Will take a look again tomorrow. I also want to take a closer look at the swaybar ends and linkages.

Just been under the car and I cannot see any signs of wear

 

[moranor@axis]

did you check the diff?

 

[Peejay]

Yep. No play. Maybe I have a cracked sub frame? Looking from underneath there was nothing. Maybe it needs to be off the car for better inspection.

Fuel tank loose? Only 1 thing left, drive it till it breaks. The only alternative answer is that it's the boy racer in you knocking to come out! :thumbs:

I think I'm going see Claude at ex Bimmerworks with it.

 

[Peejay]

Hey Guys.

After speaking with Claude and checking on the hoist, they found that the sub frame and bushes were ok.

Last night I finally diagnosed the problem, its the rear ball joints. Yey! At least I know the problem, but OEM bushes are R700 ea. I need 4.
Hpefully I sort it out this weekend.

 

[Peejay]

Its fixed. Four new rear ball joints. Feels alot more planted and secure at the back.
Wished I'd done this earlier. Next job: Propshaft CV
