Hey,

I've got a knocking noise from the rear axle, i think it might be the metal rod that connects the axle to the chassis? Torque arm is it? Pretty much the knocking comes from the back right rear. Had a search about and can't really find any. Does anyone know who can supplies that part?
Also only started happening about 2 weeks after i lowered the car.

Cheers.

it's not likely that the knocking is from that rod (commonly known as the anti-tramp bar on here)

prime suspect is the rear jacking point being able to touch the leafspring, that happens quite often.
also, if you lowered it quite a bit it might be the shock absorber that catches on the axle

Oh thanks for that!

I'll have a look and see if can sort that out. Only lowered it by 2 inches, but got adjustable dampers coming anyway.

Its not common to fail but the rear radius arm could be responsible if its loose. Is it knocking when the back end goes up or down? Could be the bush is gone or the retaining bolt is loose. Its a small bolt in a big hole, if its not tight the rod will bang hack and forwards.

The rod is to keep the axle flat and maintain the camber and toe-in as the suspension goes up and down.

It only ever happens when i turn right like hard or something then you hear a big knock. Then it continues knocking like quietly for a bit then goes away.

Zorst?

+ 1, it happened to me on the left side, but I had a horrible squeak on poor roads.
