was wonder what could cause this?

car has like 115K miles...

maybe Ujoints going out?

 

its like a WOM WOM vibration. Not a constant vibration but comes in waves!

 

Cheap and easy first....Check wheel balance.. U-joints are cheap...Might be a driveshaft...

 

got a wheel alingment just the other day.

driveshaft is stock. think it could be that?

i have sprayed alot. and also just got new engine.

But it did the vibration before, but had tranny rebuilt and it went away and now its back after new eninge put in!

 

Try flipping it over and remounting it, they seem to perfer one orientation better than the other.
