Default Lowered the rear 2inchs have a vibration now
Hey guys I have a 2018 f150 supercrew 2.7 EcoBoost 10speed, I recently lowered the rear 2 inches using a longer shackle but I noticed I have a vibration at 80 to 80+ mph and worest when I'm doing 120mph didnt have it before wondering if its has something to do with the pinion angle or maybe my tires r not balanced properly anymore. If it does end up being the pinion angle and idea what degree of shim I would need to correct the issue. I Would really appreciate the help instead of doing a bunch of trial and error. Thanks
