Dont feel like reading the whole thing again. Did OP figure out what is not aligned properly?

From the OP's other threads it looks like he was doing the work himself so odds are it has not been anyplace near a body alignment rack yet. Can align the wheels all they want it won't matter if there is some twist to the body. If the A pillar was bent as stated then there is very likely some twist someplace.

Lowering the tire pressure helped some. Im really thinking its the tires.

Hey, stubborn one ...... ;) ........ take your car here:

https://www.facebook.com/Bakersfield...2384752474766/

.......and buy 4 new tires and let them install them AND check the frame and suspension on your car and align it.

There ya go ....... problem solved ....... :thumbsup:

Have you done any measurements or inspected the subframe or anything?

Im not qualified to do that most likely ill just wait and change the tires anyway if that doesn't work then ill go from there. Just to clarity just the alignment numbers i provided wouldn't cause the car to behave like this right? Not talking about frame measurements but alignment measurements. If the cars frame was intact would my alignment numbers cause whay im experiencing.

You could have perfect alignment numbers on the suspension and the car would still act that way if the frame specs are off by even a little. This has be explained several times. Charging tires and aligning suspension may mask it for a bit but it will happen again. Get it checked before the car get totaled a second time. You are not saving any money by throwing parts at it in the hopes it is something else.

I explained the caster issue pages ago. It's differing by over a degree side to side.

New tires alone probably won't be your fix. Jack the car up, visually inspect for anything bent, pop your hood and check the strut towers.

Throwing money and parts at the vehicle until you fix it is more hassle then just figuring out the problem and the correct fix. I think a body shop will check the vehicle on a frame rack for less than a new set of decent tires.

Thought I'd throw this out since it's in a similar vein. Just in the last couple months, I've started having the Traction Control kick on during sweeping, high speed curves like entrance or exit ramps. It has never done this before.

It's not an actual loss of traction, it's like something in the rear grabs. It doesn't feel like a brake though (which it should be doing all the time if that's the case, and there's no burnt brake smell), and it's under steady power or even coasting - but not lift-off in the corner, more like off the gas before entering. I have new tires (it was doing it before and after tires). I also just had an alignment done which appeared to help a bit. Before it happened in the forties, now it happens in the fifties. Otherwise, the car continues to drive straight, doesn't pull, no unusual tire wear, no vibration.

And again, it's not just a plain old traction loss because it's happening on ramps I regularly did at 70+ with no drama. It also doesn't appear to happen at low speed.

Is it possible for the Torsen LSD to go bad or get damaged and do something like this? Just spitballin' here.

Very similar to what i experienced. Hold on now that i remember when i got the car the driveshaft was disconnected to tow it. I reinstalled it but i dont have a torque wrench could it be possible the bolts arent tight enough?

Even if the bolts are loose they wouldn't cause your issue.

Not sure why you are so dead set against having the body checked but maybe you just simply still do not understand what the problem could be.
The car was written off in the first place because it would cost too much to repair so somebody someplace probably knew the frame was out.

The doors, fenders, hood, etc can be bent and not cause any issues with the structure.
If the A pillar is damaged it can throw off the whole body alignment. It is structural part of the car. Look at the picture below. That is the structural uni-body or "frame" of the car. See how the A pillar is tied directly to the front structure that holds the suspension?

If that pillar is bent that pressure extends through the rest and throws them out of alignment. A body shop will use special equipment to see that everything is in alignment. You can measure yourself but you need to be very precise in the measurements. You can not just look and say "ya it all looks good" http://what-when-how.com/automobile/...rs-automobile/

Its not that im dead set on saying it isn't the frame but i feel a smarter cheaper possibly free way is to swap out my wheels and tires from a friend and rule the tires and rims out completely. I had him tell me it could be my cheap tires that are too stiff.
