still gonna vibrate lol

At this point, swap in just about any rear, see if there's a difference and then go from there. For all you know, the axle tubes could be bent and a rebuild will never fix that.

the axles themselves bent or the housing bent?

ive had 2-3 rears in this car lol

Part it out and sell me your trans

wait, you've had 2-3 rears in the car and the car has always made the same vibration?

This thread keeps delivering

Yes?

Pretty sure case is closed at this point lol question is do I have the time and money to do it

Was the car ever in an accident that could have bent the unibody?

if you've swapped out the rear, and the problem never left, why do you still think it is the rear?

Cheaper than a new trans :bertstare:

Not that I am aware of

Swapped transmissions, swapped rears. Only reason rear was in question is because corbos ****ed the rebuild up and left pinion loose.

Should have just went 9" or s60 lol

You checked driveshaft/u-joint angles I presume? Both vertical *and* horizontal?

Yes profab checked that all out.

How ironic would it be if all this time it was just a bad misfire from a crappy opti?

It's an LT1 so has to be the Opti duh

You had a vibration free 9 inch and could have a vibration free 385 with 10 second slips all over your interior....

I have an LT1 and it has no opti.

:bertstare:

Also doesn't vibrate, even on solid motor mounts.

Its def your opti.

Trust me. I know lol.

True true. That torqhead kit is nice

Another dumb question, is mystery vibration in your head or have others driven car and confirmed?

haha, larry felt it. thats how we found the bad u joint on driveshaft, which prompted me to get a PST driveshaft

When can I come drop the trans?

forgive me for not reading, but does the car have a body mounted torque arm?

Did. Then I put stock back in, didn't change a thing

lol

When is the part out?
