I could be wrong, but is it even possible to 4-wheel align a Solid Rear Axle anything?

You are correct.
Maybe they mean't they will check the panhard bar alignment. Although i doubt this is the issue.

Having a panhard bar could be part of the problem. If you are attempting high speed runs on an uneven/rough surface (anything but prestine tarmac), you are going to feel squirly in the backend under acceleration. The panhard bar does it best to keep the rear axle planted, but when you go over any type of bump, the travel of the axle is not straight up and down as one unit, it moves in a parabola or an arc. Meaning, both rear wheels do no touch the ground at the same time. IRS cars really don't have this issue and the best thing you can do with the rear is a Watts Link. I have one and it has helped tremoundously with keeping the rear planted, but an IRS will inspire more confidence than the stick axle we have.

Shit, mine feels like crap at 80 with 3.73's. Maybe its the Nitto 305 DR. Who knows.

[garner]

Yeah I have no clue how they're gonna do the alignment. Ford dealer service hasn't impressed me these past couple days with their lack of knowledge

Well finally got the repair order back after waiting for 7 hours.

Add to that a $100 diagnostic fee and tax. Almost $1,000!

I told them no thanks, I'll talk to geico and the body shop since the dealer thinks that the wheel bearing issue stemmed from a wreck, and discount tire should warrant their tpms sensor work

[kn7671]

If the car was in a wreck, and you still have systemic issues relating to that accident, the Insurance company should definitely be involved.

I had a similar situation about 6-years ago. The dealership just called the insurance company back a month after all was supposedly fixed, and amended the repair. Got wheel bearings replaced, along with 2-new wheels, and 4-new tires from incorrectly performed alignment during the first repair.

Its the soft sidewall of the DR's.

Everything is stock on the car except ford 07-09 polished bullitts and 235/55/18 yokohama yk580 tires(tires were purchased a couple months ago). There was very light wind(not sure on direction). Any ideas on what could be causing this? It's pretty sad when my friend's f150 is more stable at 120 than a pony car at 110

What does chasing a run mean?

Some cars were racing and he was spectating. Trying to keep up.

[MontanaBentley]

okay now I understand, thanks

My turn. What's the Mexico thing all the time?

People think by saying they're running in Mexico that they're pulling the wool over law enforcement's eyes but it's nothing more than a term for "street racing". Many YouTube videos say "filmed on a highway in Mexico" when obviously signage in the video is posted in English with many familiar looking interstate signs. I doubt anyone would want to race on a real highway in Mexico.

[Lucky13]

Got it.
