Ey guys i need help, i just install lower bolts on my 15' stingray and now is making a weird noise every time i go over a small bump or if i lift the car from the back, i try to lubricate all the bushing on the suspension and noting. plus, i upgrade the shock for a heavy one and nothing, went to the dealer and they couldn't find the problem.
Any idea ?

I wasted several months returning to the dealer to correct a groaning grunting type noise when going over aprons or speed bumps. I finally determined the ride height adjusters were the cause. They rub the suspension arms. Confirmed by spraying them with WD-40 which temporarily silenced them until it evaporated away.
