Clunk after replacing Camber Arms Rear

I want to leave work now and get on with this...... Dam work getting in the way of our tinkering!!

*UPDATE* I have had the car on the MOT ramp and loosened off the bolts and then tightened them back up again. This made slight difference but the problem still persists.

I emailed the company back and they are now telling me that I have broken the part due to fitting it incorrectly in the first place?!?! They want it returned before they send out a replacement as well which means my car will be out of action for the next week!! Such a ball ache.

Now ill have to remove the item tonight in the dark, send it off in the post tomorrow and then wait for a replacement to arrive.

The replacement part will arrive today. I will fit tomorrow and report back if the problem has been resolved.

Issue resolved! I fitted the replacement arm and no problems at all. Thank you M2
