I have a 2008 Sequoia 4X4 and have a couple questions in regards to what I'm seeing on my vehicle. First off the rear tires have way too much negative camber and the front has too much positive camber. I'm sure the manufacturer has it this way for stability and to promote understeer, but I would prefer to have a little more oversteer adjusted into my SUV via more negative camber at front wheels and more positive camber on rear tires.

In regards to toe in, I have 1/2 inch toe in and would like this to be adjusted to more toe out so wheels are exactly straight forward or no more than 1/8 inch toe in.

My front toe in, as well as, my front positive camber is causing the outer edges of my tires to wear more than the inboard side of tires. I rotate my tires frequently, but still get uneven tire wear. I just replaced my OEM tires and they had 2/32 of more tread on the inboard edges of tires as compared to the outboard edges.

Took Sequoia to dealership and they said all specs are within limits and they wouldn't make any adjustments. What are my option? Does anybody have instructions on how to adjust toe out on a 2008 Sequoia and adjust rear tires so they have more positive camber? The front toe adjustment looks pretty easy, but the camber adjustment looks more complicated.

Any help would be appreciated.

Found a good tire shop yesterday that uses the Hunter machine and we worked together and dialed everything in via a 4 wheel alignment. We first started with the rear axle and adjusted to get the least amount of negative camber (more positive camber) and then we set the rear toe to zero (no toe in and no toe out). The best part was getting both sides within one tenth of a degree of each other.

We then adjusted the front camber to add less positive camber (more negative camber), matched the caster exactly and then set toe to zero on the front as well. We lifted the vehicle with hydraulic lift on rack a few times to get weight off wheel and allow adjustments to settle in and then lowered vehicle and readjusted to get it perfect. In regards to thrust angle, it was 1 degree out before we started and we even got that down to .01 of a degree accuracy. The cross SAI was dialed in to an accuracy of .02 side to side. Cross camber is .01 side to side and cross castor is .01 side to side.

Basically we took all the "toe in" out of the Sequoia and we reduced rear negative camber and increased front negative camber. All these will make the Sequoia turn in better and will provide more oversteer vs. having all the understeer (push) that the factory provides off the lot. These adjustments along with the 20 inch wheels I just put on makes this large SUV corner much better and track very smooth in the turns. All this was done with a 114 load rating sidewall tire (2600 pounds), so these tires have not reduced my tow rating, yet provided better performance.

The last thing I want to do is use my digital pyrometer to take readings on 3 places of each tire after a long test drive and make sure I'm getting even heat across tire and no hot spots that will generate poor tire wear.
