Rear subframe shifted towards *drivers side*

[rightcoastbias]

Hello,

I recently installed Urethane rear subframe, trailing arm and differential bushings. Then I installed H&R Race springs along with iX weaves and 20mm spacers with 205/55R15's. Oddly enough, my drivers rear tire is being eaten by the inner lip of the fender, while the passenger clearances by a good 10mm.

I have driven ~300 miles with some spirited driving. I am jacking up the car removing the nuts, and letting the subframe slide up and down the knurled bolts to try reset it.

I am cutting/rolling the fender, but would like to know if anyone has heard of a subframe shifting to one side?

Any signs of accident repair? Could also be that your quarter panel placement is a bit off. Try to measure the subframe from a reference point on the chassis to check for center.

Band-aid solution: Just rolled the fenders with a torch and a bat. No more tire scrubbing.

As expected, sliding the subframe up and down with the nuts off did nothing. Some skid pad type turns in an empty cul-de-sac did nothing. Measuring from the drivers rear tire sidewall to the outside of fender, the passenger is 10-12mm further into the wheel well.

Thank you GP: The original owner said no wrecks and all panels have matching VIN. Front was resprayed due to sun damaged paint. :\ I'll compare the distance between a fin on the rear diff and the each rear shock mount bolt.

is it possible that your Trailing arms are tweeked? did you measure the subframe to check its centering?

I doubt that the subframe is the cause, a bent trailing arm or prior rear end damage or more likely causes. IX wheels have the wrong offset and are the primary cause. Rolling the fenders, if the rub isn't too bad, would be a reasonable fix.

Agreed. You should get under there and start to take a bunch of measurements. Make sure you are using something good to reference. Don't measure to tire sidewalls like you stated earlier. Measure the subframe and TA's to see if they are bent at all.

possibly you installed the trailing arm bushing backwords and slid the arm over

If you install either (or both) bushings wrong the trailing arm won't mount on the subframe.
