Rear Suspension Knock

[holmsey24]

Hi,

I know there are tons of threads about this but struggling to correctly diagnose.
Recently had fitted replacement shocks (pair of) to my 172 Cup and got a quite loud knocking noise when going over large bumps/speedbumps on the rear.
If I go over a speedbump as soon as both wheels hit the bump it bangs. If I go over the speedbump and only one wheel hits the bump on the off side for example there doesn't seem to be a bang. Only seems to bang when both wheels are hitting the speedbump.

Hope that makes sense

Does anyone have any ideas what it might be??

Cheers

Have you checked the springs are seated correctly, and that the two nuts, ie one at the bottom and one at the top on the inside of the car are fastened correctly?

They look like they are seated correctly. Nuts both feel tight.

Sounds a very metallic bang, checked the exhaust isn't banging, and whilst it does wobble a bit can't see it hitting anything if I knock it with my foot.

heat shield loose?

Will have a look at that.

Cheers for the replies
