rearend not centered

[daves72dart]

hello. the problem i have is the rear drivers side tire is rubing the outer fenderwell and the tire on the other side is rubing the inner fenderwell. the springs where moved in when i got the 72 swinger.any ideas on my problem or how to fix. thanks.

o.k.,first things first.
are you sure the tire and rims are the same size on each side?

[daves72dart]

yes thay are the same.

[daves72dart]

i will go check right now

[daves72dart]

ok the drivers side is 10 and 1/16 and the other side is 9 and 3/4. this is taken to the inside perches.

now i'm confused because it sounds like it should be rubbing the right side not the left.
sounds like your springs/axle are not centered

[west]

where does your yoke line up in relation to the center of the tunnel?

[daves72dart]

it is rubing on both sids the outer fenderwell on the drives side and the other side is rubing the inner fenderwell.

[daves72dart]

where does your yoke line up in relation to the center of the tunnel?

the engine and tranny are out of the car.

[west]

whatever is causing the problem,most likely you will need to cut the perches and reweld the housing in the correct position

[daves72dart]

so when i buy the mono leafs i will get some perches.

[daves72dart]

what do you mean by housing

[70 Dustpan]

So you need to move the rear over 1/4". You can weld the centering holes up on the perches and redrill the holes over a 1/4" on each perch.

[daves72dart]

how do you get every thing square?

[70 Dustpan]

A tape measure.

[daves72dart]

   where do i measure from to make everything square so the car dont dog track. thanks

[70 Dustpan]

It's best to pick 2 or 3 points on the car that are same side to side. Mounting points, frame mounts, things like that. Just get it as close as you can.

[daves72dart]

thanks. im getting the engine next weak.should i wait intill i get the engine and tranny in before i do the rearend .thanks again.

[70 Dustpan]

Most of the time I've done them without the motor in.

[daves72dart]

how did you get the pinion angle right.

[daves72dart]

by the way you guys are the most helpfull then any other site i have ben to.thanks a lot.

[70 Dustpan]

Unless you are changing the ride height you can set it same as stock. If you don't know the stock setting then it's best to have the rest in. But you can still center up the rear end.

[daves72dart]

i think im getting 1'' taller then stock mono leafs and the cal-tracks.

[70 Dustpan]

It would most likely be best to wait till you get everything and set it up how it calls for then.

[daves72dart]

thanks for the help guys.

I've heard the torsion bar holes in the cross member is one of the better, more accurate places to measure from.  I'll be inboarding my rear susp too in a couple of weekends, I hope to move it back an inch too.  I hope I get it all centered and dont make any 

[daves72dart]

where do i measure to at the rear of the car.thanks

[Nitrous340dart]

I would read the tech article on here about the relocating the springs, he talks about measuring the rear end square.  I thought of measuring in a X from the left torsion bar hole to the right axle flange.  I was also thinking of taking the stock front leaf spring mounting bracket off and measuring from there.  I'm going to try and measure from a couple places like that and hope they all give me the same number from side to side.  I thinking I could measure from lower control arm ball joint pivot straight back or criss-cross to the axle flange.... we'll see if it gets me a straight shot with the tape measure.

Bottom line is that your rear is only off 5/32" on each side (5/16" total).  Even if your rear is centered, you still won't have adequate tire clearance with your present wheel and tire package.  You are gonna have to get either new wheels, tires, or both.

When I installed my new ESPO 1 inch over stock springs on my 73 Dart Sport the drivers side  of the axle was angled forward. When I installed my 255/75/15 tires the driver side tire touched the front fender lip. I made a 3/8 inch spacer and now I have a 3/8 space on the front of both tires. I measured both new springs before I installed them. What would hace caused this???
