that's all they did was drive it? ask them for the runout measurements they took on the axles. i bet they didnt even measure them. it would be great if we could have the numbers posted here. perhaps some more knowledgable members could let you know if they are within spec or not. I'm pretty sure the spec would be in the service manual if you have one. Nothing else in the driveline would cause vibrations in the steering wheel based on the speed of the vehicle. otherwise, it would cause the vibration just by revving it in neutral with the clutch engaged. it sounds to me like perhaps you should find a different shop.

 

I'm gonna check the rear trans mount one more time when I get a chance. I don't think it's anything clutch related, web I engage disengage the clutch there's nothing abnormal. Or noises..

 

Well you see it isn't in the steering wheel, u feel it alittle bit in the steering, more in your feet when it wobbles real bad literally my body moves side to side. The whole car moves side to side.. It's so hard to explain

 

And I'm decently knowdged about vehicles.. This one I'm stumped on though.

 

the only drivetrain problem that would cause a side to side vibration would be the axles. the angle of the axle results in the vibration having a lateral component. on top of that, a bent axle pushes the wheel and steering knuckle in and out while it rotates causing a lateral vibration. im still convinced its a bent axle. all other drivetrain vibrations will be longitudinal and vertical.

 

There's a reason I asked if the car is slammed in the front, or ever was...

 

Take a look at this older post

Well the at is lowered.. Not slammed tho. I'm kinda leaning towards an axle also.. Monday I'm going to get it checked out again.
