UHMW bushings squeaking?

[DirtyTh3rty]

I recently dropped the rear end and put in condor UHMW subframe and RTABs. I had them in for about a day before I hit a curb at about 25mph with my drivers side wheel. I replaced the RTA because it was bent slightly toe'd inward.

Wheel is straight now and drives fine but now I have a creaking coming from my rear every time I take off from a stop or change gear and get on it and the rear is under load. Its coming from both sides it has flexing or binding kind of sound to it.

I was thinking the RTABs cause I didn't put any grease because I thought the UMHW is self lubricating so it shouldn't need any right? my end links are pretty cracked but they have been for a while. Could hitting the curb at that speed have done anything to the subframe or something else to cause the squeaking?

Any help is appreciated, Thanks

Poly or UHMW trailing arm bushings need lubrication to prevent the squeaking. That lube usually to be redone on a yearly basis.
