i was wondering about some tricks i can do to stop the vibrating rear hatch window it does it when i hit bumps or when the subs on. will some kind of weather striping work ?

 

Year,make would be helpful

 

judging by the pic in your avatar, its a second gen 2 door...
as for the rear window, there usually is a bit of room for adjustment on the latch that holds the window. pull off the gate panel and there will be some bolts, play around with it until it does not rattle anymore. most blazers have this problem, some have good luck with adjusting the latch, some dont, I have with 2 of them. Trial and error. Now the only vibrating on the truck is from the outside when I am playing the sub.

 

yes its a 2001 zr2 thanks ill try it out.
