Thread: help vibration

So i have a 2003 gp gtp motor has 19,000mi. and the tranny has 10,000mi. on them. I have a bad vibration under moderate to hard engine loads. It feels like the motor is on the firewall and you can also hear it. i am worried i checked all the motor mounts they are good and i power braked it and the motor moves like two inches. please help to keep me from pulling out my hair.

i have a fwi, u bend delete custom cat back

oh and did all the maint. 5000 mi. ago plugs, wires, fuel filter, fuel pump, tranny service, wheel bearings was what i thought it was , struts.

the dogdones are good they didnt have any cracks

if you turn it gets worse and it does it anytime your in the gas more than 50%

i checked the axles and one was bent dont know how. so i replaced that and the wheel bearings cus i made the ebay mistake and they lasted 6 months and were grinding. But now i have a awsome job so i am going to do the other axle and mounts to see if that fixes it. if not im throwing parts at it cus the body does have 140,000.

Not sure how long you've been having the problems..

Obviously work was done with the engine and trans, just wondering if you checked the mounts underneath. If you have been having problems since you worked on it, you might want to look around where you were working, check the lower mounts and trans mount.

yea thats the only thing i havent checked yet. and the dealer did the work and put a crate engine in after the 3 used engines the warantee company bought that either spun a rod bearing or sent them thru the block. yea i wasent happy to pay for my car for 3 months and it be in the shop. sorry touchy subject but soon i will really find out cus im buying a computer, pulley, cam, headers. and im doing it just to piss off all the ricers in town and in the only one in town with a modded gp and everyone talks crap and says they cant be fast.
