Just got done putting my tires and wheels back on and noticed the my tires are setting off to one side (the Passenger side) about 1 inch farther out than the drivers side , Is this factory or do I have a problem? The rear end is all new from lug nut to lug nut . I have driven the car down the road and had a friend follow me and it is not dog tracken at all .. just one of them little things that drive me crazy.... Here is 2 pic's ...

I've yet to meet a 79-up Mustang with a solid axle that wasn't off set to one side by some amount. It's just a characteristic of the type of suspension. It can be cured with a panhard bar/torque arm/high dollar suspension, but there's not much more than can be done without throwing a bunch of money at it.

Did you replace the upper control arm bushings? Did you put the sleeves back in the correct location?

most are adjustable on car, if not drop the front (top) bolt out and set it to 9" both sides to start if its a stick car

They are adjustable , I looked at them both and the one on the passenger side looked like it was stretching the bushing so I pulled it and gave it the 1/2 inch it was lacking from matching the other side put it back in and I still have the same problem, Axle is not cantered in the car... off by a 1/2 inch .. the top control arms are set at 9 1/2 inches and it is a stick car .... should i set at 9 inches ? I drove the car and nothing is making any noise ... suspension is set up for the strip, hit a bump in the road and you feel it...

get sum measurments from under the car to the torque box centerlines, make sure the car is square. ur torque boxes could be pulled and that could also be ur issue. If thats the case u might need to set ur rear arms up to compensate for it

i had a radius rod style upper control arm with heim joints and the part that went into the upper torque boxes had spacers. well the arms didnt come with instructions so i just installed them. my rear end was off to one side. i thought hmmm...and got back under the car. i had installed the spacers backwards flipped them around and was good to go.

FWIW, there is 3/4" offset built in to the driveline in the car, be careful where you are pulling your measurements from. The motor all the way back is offset 3/4".....

I see, said the blind man...

This is a fact I recognize, but had forgotten. I feel like that saying, "I've forgotten more about mustangs than..."

I have heim joints on the upper arms and the spacers are the same size .. I will do some measuring today to see if i can find out what is going on ... My torque boxes have some damage but are not broken and have not been upgraded as far as i can tell, looks stock.. Looks like some one used it as a jack point ..... more than once .. i will take a few pics today ...
