Did u mark the drive shaft before you took it out to make sure it went in exactly it came out I mark the ujoint and the yoke one rear so they match going back in . But is possible a weight fell off

Did u replace the flywheel when the clutch was done if so make sure it was the right one they have a weights on them too I think

Check your harmonic balancer and see if it has any wobble to it, that will definately give you the shakes.

He said , Replace the fan there's some hairline cracks?
