Hello, newbee here with a ?. I installed a 3 1/2 lift, all leafs, shocks, transfer drop, etc... All went well, but now when I drive I hear a kinda of rubbing, grinding, woosh woosh woosh sound. sorry only way to describe it. I think it's from the rear driveshaft. The leafs had wedges built in them. Do you think my angle is off?? thoughts?
Also I hear it only at above 15 mph and it is louder when I accelerate.
Thanks and Merry Christmas.
