OK...maybe im nuts...i replaced rear sway bar with ADDCO 7/8 bar with poly bushings...nice noticeable difference in rear...and cheap...but ,here's where it gets weird...my steering wheel was always perfectly centered...now its off to the right a bit. If i center wheel...car goes left. If i just let go of wheel...car tracks straight as an arrow...could a rear bar change upset wheel alignment...or steering wheel centering? anyone who has done a similar swap...any input? Thanks to all in advance!

 

Yep, you're nuts!

 

Did you have the suspension hanging when you installed the bar? Suspension parts are supposed to be torqued at normal ride height. You might try loosening all the bar mount bolts slightly and then re-tighten with the vehicles weight on the ground at normal ride height. You may have to use a 4 post hoist or pit setup unless you can reach the fasteners. Maybe one of the poly bushings are so tight it's pulling on the lower control arms throwing your alignment off slightly. That's all I can think of.

 

Are the links adjustable?

This theory might be a stretch, but assuming the car was rasied and supported near level during the bar installation, after one link was installed, did you have to force the bar one way or another to get the second link instaled? If so the bar is twisted or the mounting hardware (including links) are not symmetrical and you now have some dialed in weight transfer. That could change the wheel and steering balance.

One test is to unhook one of the rear links and see what your steering does then. If the problem goes away, then your parts are not well made. If not, then maybe your suggestion is correct.

 

Here's a picture that might help. http://bradbarnett.net/mustangs/timeline/05/05/64.jpg I like RadBoss's theory.

 

Hello and thanks for the reply...no...no adjustable links...just like factory only bigger. I had suspension loaded as well...not hanging down..i'm gonna loosen it all up and see if bar moves any by marking it...maybe it is loaded somehow...it's weird..

 

Thanks for pic

 

I have not messed with the sway bars on this car, so did not realize there are no end links. None the less the bar or the support links may be off and the way to still check is un hook / remove the bar and see what happens when you drive it.
