I've had a knocking/rattle from the rear offside.
I thought it was something to do with the Towbar/lighting i fitted...After striping the boot out about 3 times and damaging the shock absorber i think i've now located the source ..But i'm a car numpty so not sure what its called

thanks nyck

Thats the rear anti roll bar drop link.

Hopefully you may just need new bushes

I picked one up yesterday £14+vat..Hopefully that will sort it
