Right front clunk? (e30)

[Venatus 2]

Ok, this is driving me mental, I cannot figure out what is causing this.

Everytime my right front wheel goes over a bump, there is a big clunk.

When I rock it up and down on the right front wheel there is a small clunk.

Does not occur on any other wheel.

All the bolts are sh*t ton tight for all the suspension, and the clunk appears to be coming from the spring perch on the bottom, from what I can see.

Just took it for WoF, no mention of the clunk from them, at least if theyd noticed then Id maybe know what it is!

Anyone got any ideas, or take it to a mechanic?

Sway bar mounts and links checked?

Check the nut on the top of the shock too, had mine come loose and had a knocking sound.

Sway bar mounts and links checked?

They appear to be there, and quite tight, the sound seems to come from up by the spring, when im lying under it with a mate rocking it anyway,,

The top shock bolt was my initial thought as well, trying to tighten them more twists the upper spring perch and you can hear the spring grating...

I may have to find a pair of spring compressors to borrow, take the whole thing apart and put it together again haha.

Check the threaded cap on the top of the strut tube that holds the shock insert into the strut. It's under the bump stop gater. No6 in this diagram

Had this, same noise, took to mechanic, lower control arm mount, new arm, $200 = solved.

Thanks glenn, that sounds like a very possible idea, will check it when i get home.

Which lower control arm mount was it? The lollipop? or one of the balljoints?

Hopefully its not the lollipop, powerflexed those things a couple months back

[Dr. M 10]

Pretty sure it was a ball joint, I may still have the receipt (since sold car), can check for you tonight.

Sorry Bradd lost it. If you take to a mechanic, have them drive it around for a bit first. Not sure if yours does this but mine didn't start clunking until warm. Cheers.
