I have the same clunk, I thought is was the heim joints binding up in the travel arm ends, and that is what I was told by a few people. I have lube them but still have the noise. This rear was rebuilt to 354 gears by the previous owner back in 96, I am looking at the receipt and it says one bottle of additive. As far as I know I have Salibury unit with dana gears. Can somone give me the amount of fluid with the additive I should have...maybe even the proper proceedure for changing it.
Thanks...Dave
