Alignment specs??

Fletch Lives · February 4, 2019

Im currently seeking the alignment specs for 2019 Sierra Denali. When I purchased the vehicle the steering wheel was off center. The dealer I purchased it from performed a complete caster, camber change using older vehicle specs. The feel is completely different, and worst part is my steering wheel is more off center than before. Ive spoken with other local dealers, and no one has updated alignment machine specs. Also my tires are starting to wear unevenly and cupping. Can anyone help me out??

Hard to believe your dealer doesn’t even have them, although could be possible.

I’m sure someone has them, there have now been quite a few lifted new models now and I’m sure they’ve been aligned properly. Curious as to what you find on this.

Has anyone had any luck with this yet?

So Ive had 4 alignments done on my vehicle since date of purchase (9/26). Everytime I get an alignment sheet printout the vehicle specs are completely different on each one. I find it hard to believe the alignment specs for 19s are the same as an early 2000 truck. My alignment has never been fixed or straight. Literally just picked it back up from the dealer this morning because my front end felt like it was shifting around or going to fall out. Plus my steering wheel would be 30 degrees out to left or to the right for me to be able to drive straight. They told me " something was loose" and would not give me any further information. Then they charged me for the alignment. Side note: this dealer performed last 2 alignments 1 -2 months ago. AND... my steering wheel is still not straight! Not a happy camper. The alignment sheet specs literally show they picked every selection possible including suspension selections. I dont think anyone knows at this point. Ive been to 4 dealers, spoken with techs, advisors, and all the way up to the GM. No one can give me any answers or willing to help at all

ANY GM dealer doing the alignment can pull the specs STRAIGHT FROM GM. This would be under the assumption that Hunter (or whatever rack brand they use) haven't updated the specs on the equipment. A dealer not pulling these from GM has a lazy tech/is a lazy dealer.

For those wanting, here is the 2019 T1 specs (NOTE: Z7X is Trail Boss/AT4 specs. it shows them as -Z7X (not a TB/AT4) and +Z7X (its a TB/AT4):

Just an update. Tech was aligning a 2019 for steering concern with our Hunter Hawkeye Elite (one of the GM recommended racks) and it did have the T1XX specs loaded in the system.

How much weight is in the box of the truck? Express vans are known to eat front tires when there is too much weight on the nose as a result of too much in the box and especially if its too far up front.

Any good shop can align it with the specs in the machine which are factory specs. Make sure you bring it to them how you operate it so if its full to the top daily, bring it in like that so they can compensate for the weight. They can probably add a touch of positive camber over stock as well.
