I dropped my truck in Jan. and ever since I have a noise that I believe is coming from the driveshaft due to the pinion angle being off. well today I notched my frame and while I was there I decided to get some 2*angled blocks to fix the noise issue. well, it didn't change shit. now I am pissed. I am dropped 5 in. in the rear using belltech leafs and 2 in. blocks. wtf to do now? I am guessing I should go have the angle measured by a professional. any suggestions???
