I recently purchased a 99 Suburban LT to replace our 99 Z71 that was having many issues even though it has only had 5000 miles put on it in the 10 months we've owned it. Suburban today and I am thinking the rear shocks are mounted upside down. The rear shocks are mounted with the moving shaft pointed down. So which way do they go?? All of the vehicles I have ever messed with rear shocks on they have been mounted with the shaft pointing up. If the shocks are mounted upside down would that make any kind of difference in ride quality?
