Hello guys I've been lurking round in here for a while this is my 1st N post..
I own a 2015 yukon denali xl and the shocks and been make a thumping noise and the whole truck been lucy goosey for a bit now..my local mechanic said it was the shocks and struts and if I order a passive system he would install it and Would be money ahead.. So far the ride isn't bad but I still hear clunking in the rear from time to time.
I really don't tow anything but y 16 ft fishing boat here and there.. could it be the swaybars??

Please explain the clunky sound more completely, and we''ll try to help you identify its source. When does it occur? What specifically are you doing when it occurs?
