Can't figure this out...Please help on vibration

[hollywoodstang]

Alright I just changed my old worn out parts such as engine mounts, trans mounts, pulleys, harmonic balancer, thinking this will sove the problem. after all this i still can't solve the vibration problem coming from my car....WTF???

It started out of no where and i thought it was either engine mounts/trans mount or harmonic balancer.....even fearking pulleys was pulled and reinstalled!

What do you guys think it is??? should i pull out the driveshaft? check the u-joint, check the bearing retainer??? when i installed the driveshaft i didn't change those...or it might be a rear end??? i have auburn posi rear with 4:10's

Or might be my flywheel? I have no freaking idea....HELP HELP HELP it is annoying!

Any thought would help. Thanks guys

I would check the U-joints first. Do you still have the stock driveshaft? Alot of people switch to a aluminium driveshaft with 4.10s

 

[hollywoodstang]

yeah i still have the stock shaft you want it?

 

[hollywoodstang]

I have the aluminum driveshaft already....that's why i am even more puzzled....

 

[ThrashN]

Check the U-joints then

 

[hollywoodstang]

No it can't be the u joint because it came with the new driveshaft....could it already gone bad???? i had this driveshaft for only about a 3 months

 

[ThrashN]

maybe the driveshaft is out of balance or bent

 

[hollywoodstang]

balance the driveshaft....? i don't have that much horse to bend the driveshaft but balancing the driveshaft should help....? what is the step to do this? I have never done this before.

Thanks
