Why does the entire rear sit off center? This is the Ford rear, but the Mopar one did a bit also. Is there a way to correct this? The car has never been wrecked to my knowledge. I bought it from the OP,who was literally a little old lady who only drove to church in it.

The pass side tire sits about 1" from the fender pinch weld, and the driver's side sits about 1/2". Is there that much tolerance in the manufacture of these things? Is it possible to loosen the bolts and crab things over a bit?

To my eye, this makes the two sides of the car look very different. I am considering putting a 1/2" spacer on the right side rear wheel only. That would involve pulling the axle and changing studs. This is a future project, but just got the rear in last night, and went to bed thinking about it.

Thanks. Sam

Sam, you are only talking about moving it 1/4" if you can shift it that far you will be at 3/4" on both sides.

It is probably build tolerances in the car not the rear. That's my guess. Ryan's Dart and my Valiant both are offset a little too.

You may be able to oblong the the hole in the spring perches and shift it over a little that way.

I believe both of our rears are shifted to the right? :)

The rear axle in my Aspen is also shifted to one side, and I read in one forum (Dippy?) about a guy that intended to replace the spring mounts on his rear axle for the same reason, but when he measured them on the dismantled axle, the bracket were actually correct. I have seen comments on the subject many times, it seems like the axles were just sloppy fitted on some Mopar assembly lines.

The entire drivetrain is offset to the passenger side to make more foot room for the driver beside the trans tunnel. :D

The offset also helps steering box and starter clearance, as well as lets the u-joints operate properly to prevent driveline vibration. My '56 Plymouth is offset over an inch.

Simple answer:


' Cause it was designed that way.

This rear sits to the left, not the right.

This is due to manufacturing/assembly tolerances, I am pretty sure. The question is: What part of the car do I use as a reference for alignment? I would start with wheel spacers, but if it drives well, the tires don't rub, and you are happy with the look, it might just be best to leave it.
