You might also check the transmission fluid level. Removing an axle
shaft will always cause a little loss of fluid. If the loss was more
than a little, the transmission might be low on fluid and that would
surely cause a whirring sound. If the noises occur with the vehicle
stopped, tranmission in neutral and clutch engaged, then it's the
transmission. Particularly so if the noise begins when the clutch is
first engaged while stopped in neutral. Good luck. Al
