new rear problems

[blue87lx]

just put a new rear in the stang. its out of an 88 thunderbird turbo coupe. now the stang sits up high in the rear and gets bad wheel hop. we measered everything all the mounts and locations on control arms are the same. any ideas guys?

anyone?

What springs did you use? When I swapped a TC rear into my old stang I bought stock Mustang springs from Autozone. Non progessive.
Sat just fine.

There should be no difference in ride height.

As a first shot, jack it up and set the axle on jack stands, then loosen all of the control arm bolts/nuts. Make sure the springs are sitting in the spring pockets properly, bounce it several times and tighten the bolts with the weight on the axle. It sounds like you jacked under the body.

we used stock stang springs.. i dont know what it could be. we had the car on the lift, put the rear in then used a tranny jack to push the rear up and tightened all the control arm and shock bolts

I have a couple thoughts. One it sounds like you covered already -- that is the suspension binding. The control arms need to be tightened with the suspension loaded. Jack the car up by the rear axle and break the control arms bolts loose -- then retighten. Be careul -- if it is bound it could pop and drop down a bit.

The other thing is the springs. If there are rotated incorectly, they could cause the car to sit higher. If they're stock springs, the pigtails should both face the driver's side. BOTH of them need to do this.

one more vote for the suspension being binded.

Do you still have the quad shocks hooked up? The bolt hole for them needs to be moved lower on a tc rear to work on a stang.
