Rear subframe adjustment - pics/write-ups?

[Satan]

Okay, so the driver's side rear wheel sticks out slightly more than the opposite side. causing some slight rubbing issues.

Anyways, seems that other may have the same type of condition... http://supraforums.com/forum/showthread.php?t=551627

Also seems like it'd be easy enough to loosen the SF bolts and slightly slide, like it says in the able link/thread.

However, I don't plan to replace the bushings yet and want to make sure I do this right (without removing every other suspension component).

Anyone have a pic which points out which are the subframe to chassis bolts and/or a write up that already has tips/tricks, and gotchas? I did not see any when searching the poly subframe bushings threads.

Thanks,
Elvis

I loosened up the bolts and attempted to shift the SF a bit, but did not do any good. I received a set of SF poly bushings, thanks to George @ Raptor Racing!!!!

Will be installing them early tomorrow and would really appreciate it if someone can post some pics, tips, or anything that would be helpful to doing this. I am sure I can figure it out as I go, but would really feel more comfortable with something to go by or have studied.

The TRSM only shows where the bolts are, for retorquing the SF at some point in routine maintenance (maybe 80k miles).

theres no adjustment for the sub frames. most likely you car was in a accident.

One of the guys on SF said that they shifted it "slightly" over. From what I saw when I loosened, it may be possible. I only need a millimeter or 2...

 

[hvyman]

you need it to be adjusted this - much? hows your alignment?

 

[Satan]

Alignments have been good, but that rear, driver's side is at the very max limits... Springs/struts, poly bushings, etc... most of the suspension is almost new.

Doesn't appear to have been hit in that area. The car had been hit in the passenger side front corner, but not anywhere near the rear. All that's left that has not been replaced/renewed are the subframe bushings. There is some "slight" adjustability in the subframe, according to someone else in that thread who had a similar issue.

Figured I'd do the bushing replacement, then re-align and see if there's any improvement.

Get a complete alignment. It shouldn't rub unless you've change something or don've some sort of mod to affect it.

 

[Satan]

Like I said... had multiple alignments and the rear driver's seemed to be maxxed out. I replaced the stock bushings with the polyurethane ones and all seems well now.

I did a simple write up on the process and posted it to the group buy thread.

I can hear the diff. spinning up a bit louder/clearer than before. Torque/weight transfer has improved, body roll has been reduced, and no mopre tire rub on the driver's side rear tire. More testing to come ;-).

This was a great mod to have done. I wouldn't have imagined that the subframe bushings made this much of a difference, but I guess the stock ones were wore out significantly (and I had been used to 'em). The old ones were bad enuff to cause tire rub and alignment issues.

was ur car loose. like if u wiggled steering wheel back and forth would it feel like the ass is swayin. cause thats what mine feels like

 

[Satan]

I really did not sense or notice the slack in the rear suspension, until after the new bushings were in. Then I could tell that the slack was gone. It may be that the stock bushings allow for some slack and the poly ones don't. I do think mine were wore out and the replacement made a bigger difference than I expected.
