Knocking from rear.

[MONKEYSOCKS]

Any suggestions welcome. Since January I've had the following done, just to help rule some things out.

 

Invidia gemini exhaust

Cobra hfc's

Front & rear ultra racing braces

Front & rear Whiteline arbs & droplinks

Tein s springs

New oem top mounts and bushings

Bilstein b6 shocks Front and rear

Polybushed rear lower shock bushes 

Dba t3 discs all round

Performance friction pads Front & rear

Goodridge braided lines

Japanese racing spacers

Tarmacsportz rear camber arms 

Full wheel alignment in September

 

Knocking is only on uneven road, not over speed bumps. Feel like it's coming from rear left.

Are tie-rods and rear shocks all torqued up? Ive had it on another car where i hadnt tightened them up quite enough and that was enough to cause a knocking.

Rear shocks are definitely torqued, been told I need new tie rods, next job to do.

Was thinking it might be rear upper control arm bushings?

Could be one of numerous things.

 

As a process of elimination, try disconnecting both rear drop links and take it for a short road test.

Cheers mate, I'll give that a go. Took the spare tyre out and can't here it as often now, maybe taking the weight off did something. I'll keep investigating.
