Hello, i need some help with my 2016 Yukon Denali... so here is what’s going on and what I know... I took it in to the dealer 2 weeks ago to have the Magna Ride shocks replaced in the front.. I asked them if the rear air rides were fine and they told me they were just fine, I Imediately noticed a better ride when the front shocks replaced but started noticing a very loud sound every time I would go over any type of bump. So I called them back and ask them if they were sure that the rears were fine and they assured me they were. After some personal investigating I noticed that the driver side rear is very soft and bouncy and and the passenger side rear is extremely stiff. I did test the air compressor and seemingly working OK. Does anybody know why one shock would be very stiff and the other shock would be soft? Additionally I took it to a local suspension shop and they also told me that they were fine. I find it very hard to believe that one shock is stiff and one shock is soft. I noticed on the stiff shock that it looks like there is a little bit of dust buildup on it indicating a possible leak of fluid. So I did another little test on my own and I took the truck over some speed bumps and the driver side rear when I went over the speedbump glided right over it and made no road noise I can’t say the same for the passenger side rear when I went over the speedbump it made very loud noise and it was extremely stiff .
