I have an 87 245 that has had a rather noisy rear end. Just replaced the trailing arm bushings yesterday and it helped a lot but there is still some noise especially at coast/deceleration. In fact, under acceleration the noise is all but nonexistent. I read somewhere on the board a suggestion that "lucas additive" might help....Anyone had any experience with this product or is there a similar product that might quiet down my differential? I put in a different set of halfshafts/bearings before the bushing job and this did nothing to help the noise. I just thought I would try some other kind of lube in the pumpkin before doing torque rod bushings or something else....any ideas? Thanks.
