Bongo Fury

Hello all.
I`ve just had all my anti-roll bar drop links,and D bush`s replaced with new brackets,front and rear.
The trouble is the rear end still knocks on rough surfaces.
Is there anything else at the rear that is known to knock??
And i am referring to the "rear"of the van!!!!!!!!!!!!!!!!!!!!!!!

If you don't have a spare wheel underneath, then the bracket that would hold it in place can knock around.

Give the exhaust a good waggle and jack up each wheel and give them a good waggle, too.

next easiest to check would be the shocker mounting rubbers and shocks themselves.
