After getting sick and tired of having to disassemble the rear suspension every winter to re-lube the poly bushings due to the horrid squeaking, No matter what lube I used it always dried up. Tried drilling and installing zerk fittings and it never lubed everything properly but would squeeze the bushings out slightly. I installed the stock upper and lower trailing arms. Man oh man what a difference in ride and even stability in the rear on the street. I have a rod end panhard bar so it keeps things lined up back there but didn't realize how jarring the ride was from the bushings. The poly was almost adding a very stiff shock effect I guess due to the stiction when rotating. Best case scenario would be to rod end the whole rear end but since this is a 80% street car I will probably hold off on that. I'm debating changing the front control arm front bushing back to a rubber stock type but keeping the rear hydro bushing as poly because the stock one is just way too soft. Just wanted to see what everyone else's experience was with the poly and different bushing types.
