Carried out the inaugural road test of Bev the Chev, engine and gearbox were running fine but the run was curtailed to investigate an intermittent screeching noise ( sounded like dry water pump/ fly wheel pulley rubbing on sheet metal ). After running on stands the noise was traced to the torque tube/ prop shaft and on stripping down the nose bearing was found to be badly worn allowing the prop shaft to rub on the felt seal washer.
Looking at the prop shaft it is not sitting exactly central to the torque tube, viewed looking back down the car it sits slightly to the right.

Now my question is, is there any adjustments that can be carried out at the diff end to move it back to the centre or is it just how it is? (the prop shaft isn't bent as when revolved it stays in its current position without deflection.)

From your description your torque tube may be bent. Very accurate measurement of the tube front end to each outer backing plate will determine if it indeed bent. It is not a tough job to straighten. It often can be done in the car. If only a small bend a jack against the frame may be all that is needed. If it needs more straightening it may require heat near where it meets the rear axle housing. I have had to straighten a couple torque tubes in the past.


How Sweet the roar of a Chevy four!
