89 buick rattle problems

[Twistid 5,000+ posts]

89 buick with 12" L7 + hifonics bx1500d, sounds like my car is literally falling apart on the outside

i tried to find the source of "most" of the rattling and it seems that it coems from underneath the car near where the suspension is... also the muffler/exhaust pipes are rattling quite violently , but its mainly comming from underneath the car... sure the trunk lid is rattling but its not nearly as loud as whats rattling under the car ...

would there be any way to fix this, or im just stuck with it? i dont think i can just dynomat the undercarrage lol

um you can do a couple things

lay dynamat on the floor (under your carpet ... duh =P )

go under your car and put ur bass at a lower level where you can begin to here things rattle and put your ear close and try to find the parts

- you can remount your muffler

- put silicone between 2 peices of metal (did it with my lisence plate) silicone works very good with that

- have a mechanic check out your suspension that doenst sound healthy
