Engine/Transmission (1998.5 - 2002) new South Bend clutch---new vibration

[DEspen]

Has anyone had a new vibration at 70 mph or so after installing a new SB 13-1. 25 CON OFE clutch and flywheel ?

Any vibration that could be caused by a clutch assembly would occur at a given engine RPM in any gear, not only in top gear at 70 mph. Stated another way, if your engine is turning 2300 rpm @ 70 in sixth gear and you feel a vibration, you should be able to feel the same vibration in fifth gear at 2300 rpm, 4th gear @ 2300 rpm, and so forth. The vibration should be independent of road speed if it is caused by a clutch assembly problem.

If it only occurs at 70 mph disengage the clutch, shift to neutral, and determine if you still have the vibration. If you do it is caused by wheel balance, a bent rim, a driveshaft imbalance, etc.

A common cause for this is when you drop the drive shaft,you do not mark the ends so you have it lined the same way. If you had someone else do the work,it is likely this is what happened. A lot of the younger gen. don`t this old rule I learned in the mid-50s. Good Luck

I don't have a vibration but now my NV5600 grinds when shifting from 5th to 6th. Especially above 50 mph.
