I recently did a 2in lift and stared to have symptoms including noticed poor gas mileage and a rear rear right dragging caliper. I replaced the rear pads rotors and right caliper the problem is gone. Then my rear left caliper starts is stuck in the closed position. Im going to replace my rear left caliper.... but would a LSPV cause the symptoms I'm having? My front right brakes seem to be fine.

Also, I'm not the sharpest tool in the shed but i dont fully understand how a body lift would effect the LSPV if the spring is connected to the axle and the frame, the body lift is between the body and frame and would seem to have no effect on axle and frame distance?
