Sound After Installing LCA, Relo Brackets, and Panhard bar.
I have a 2012 5.0 with Roush Extreme Lowering Springs. My buddy sold me some parts from his car he was returning to stock to sell. I got Whileline Relocation brackets, LCA and Steeda Panhard bar. I installed it and drove it home. I had a metallic rubbing/scraping sound coming from the rear. sounds like right rear but it hard to pin point from inside the car. I thought that maybe the Emergency cable was to tight from taking the cables of and putting them back on. I don't think that is the issue the sound is constant and changes with speed. does not change with brakes on or off. only time it goes away is about 1-2 seconds after a downshift. My buddy did similar mods and has the same sound. I heard 2 things. One was that it is the pinion angle is off. the second is it can't be the pinion angle since i have a 2 piece drive shaft. The fix i was told is a adjustable UCA to correct the pinion angle. Anyone have any useful input. Thanks.
