Rear alignment question

[GrantK]

What are the best locations to use for checking the rear wheel alignment?

In particular
*) Checking side-to-side positioning. Since I've lifted the truck it will now be offset slightly to the drivers side and I need to adjust the track bar to bring it back where it belongs. I assume the axle should be centered, correct?
*) Making sure both sides are equal front-to-back. Also, what is the ideal measurement for this?

I still need to add the other heavy mods that will change the height of the lift before doing a final check on these but curiosity is getting the best of me.

Here's another thread on it...http://www.toyota-4runner.org/5th-gen-t4rs/106490-2010-4runner-rear-wheel-alignment-specs.html

Checked both the factory repair manual and the collision repair manual and found nothing on rear wheel alignment other then the factory rear measurements in the collision repair manual on page 38.

The factory rear pan hard bar,upper links and lower control arms are not adjustable so they wouldn't give a way to align with them in the manual if they can't be adjusted. It does give runouts to see if the rear hubs are warped but the axle itself is a straight axle set up with the emphasis on straight.

The pan hard bar would adjust the whole axle side to side as one end is attached to the frame and the other the axle so you would just want that centered left to right or back to stock as in lengthen it a little.Maybe the caster is changing a wee little in the rear as a lift would pull the rear axle forward and lengthening the lower control arms would adjust that,and again back to center or the stock position for and aft.I'm sure a good alignment guy would know how to re-center them.

I don't see anything that could mess with camber and toe should be fine as long as both links and LCA's on both sides were set the same length.

Not many people fool with rear alignment on a 2 inch rear lift as it's not out by enough to worry about.
55k miles on my 2 inch rear lift and no unusual rear tire wear or front tire wear for that matter, is the only proof of that that I have.

Thanks.

Yeppers, I don't expect it to be off by much, maybe .25-.50" side-to-side, but since I have an adjustable ICON pan hard/track bar it makes sense to get it as close to DNC as possible. I also don't think the front-to-back will be wrong but once again, since my link bars are adjustable, it's worth checking and maybe adjusting. I like to keep things as close to ideal as possible (also know as being anal retentive) when it comes to my ride.
