Steering wheel off after doff swap?

Do not really know what is generally disconnected in order to swap out that differential. I wonder, if enough of the rear suspension must be torn down/disconnected to allow for the install, could you accidentally create a rear wheel stagger (fore/aft dimension condition) upon reassembly. If that can/could happen, could that in turn influence how the front steering might react to correct any misalignment from the rear wheels.

Yes, rear alignment isn't connected to the steering wheel. Though, have you ever seen a car or truck in front of you with the rear end misaligned from the front?

If you removed the subframe to do the work, then reinstalling it using the guide pins should have aligned it within tolerance. The thrust angle (had to look that up because I forgot what it was called) in a case of misalignment to the right would be a positive discrepancy. To correct, your front wheels would need to steer to the same angle.

Your car goes straight, but is slightly off axis and traveling partially sideways.

Go to the shop and get an alignment check and they'll be able to correct it.

There's no way around it. Your rear end isn't aligned with the front end based on what you've said.

Test it in a parking lot. Drive in a straight line (wherever the wheel ends up being). Stop and get out of the car. Your front wheels should be straight. Any deviation should be noticeable.

It must be very slight.......

The vehicle will need a 4 wheel alignment. Front wheel alignment is based off of rear wheel straightness. When doing an alignment you must always do the rear adjustments first, once those are straight, then the true readings for the front are indicated.

If the wheel was straight before, chances are the machine will SAY the front is incorrect as well as the rear, but once the rear is corrected first there is a good chance the front numbers will move back to straight without even touching them.

And whether dropping the craddle or just unbolting a few control arms, once the tension on the arms and bushings are released by the bolts, things shift. The proper way to tighten suspension is to have load on the arm and bushing before fully tightening. Most dont do it because its a real pain on the ground!
