Just had SFC's installed a few weeks ago. I now have a very noticeable clunking noise coming just from the rear. Seems that it only happens when the rear tires go over a large bump. Front chassis is completely unaffected. They are UMI tubular weld in. Just curious if anyone has had this problem, or if it is an install mistake.

 

tighten the rear of the control arm mount up to 90 ft lbs. Since the SFC mounts around the control arm mount it doesnt allow the bushing to compress, that should fix it.

 

I think he meant to say tighten the front bolt of the LCA; many SFC's mate with the front bolt.

 

Yes sorry this is what I meant, tighten the bolt where the SFC goes around the front control arm mount.

Thanks
