Just got back from Dynamic Diesel & Bear Alignment in Snohomish, WA. Very impressed.

Quick work (in-and-out in right about an hour), and done right. The alignment guy there is apparently the third generation of the original Bear Alignment owners/founders and has been doing alignments his whole life. He was able to get me to 3.6/3.7 Caster, 0.00/0.00 Toe and 0.00/0.01 Camber. Steering wheel is perfectly aligned.

Silly Les Schwab saying I was maxed out at 1.6 caster.

Driving home, truck felt very stable and the wander is all but gone. There's still a hint, but that's easily explained by crappy, gooved roads and wider tires. I'm more than pleased with the results, and the customer service was excellent. The true testament is that they are this good at 4pm on a Friday.

Yea that thing should drive like a champ. The tires will give ya the wander now. That goes without saying though.

yep, and I completely understand that a lifted truck with larger, wider tires on it *will* handle/drive at least a little differently. this thing drives great now!

I am desperate to fix my wandering issue as well, what does too much caster cause in terms of tire wear or handling issues etc? I was thinking of going back to the shop and telling them to set caster to at least 3 after doing a check for worn components of course. Right now caster is at 2.0 and I am bone stock on everything. Basically wondering what adding a lot more caster would do in terms of handling/wear on a stock vehicle?

thx

Someone with a better understanding of alignment adjustments should chime in, but I don't think caster will affect tires wear one way or another, just steering and straight line stability.

With sufficient thrust, pigs fly just fine.

Correct ^^^
Caster only affects the vehicles self centering characteristics, and when turning. Too much, and the steering effort increases, but vehicle is less likely to wander, too little, and steering is easy, but vehicle can wander. Im over simplifying it, but thats the basics.

Spot on! Caster has no affect on tire wear. It only affects handling and steering recenter.
