Hello all, changed the uj's on my truck and it's still knocking if you accelerate quick going round a corner or pull away from up a curb or pull away quickly it's not all the time but most of it, I noticed while under the truck one of the rear shocks looks like it's blown as it's covered in black oil and the other isn't, I can't see how that's linked with the knocking tho, any help would be good otherwise I'll have to take it to the garage
