Alert Axle shifted - Spartan Chassis on Newmar Dutch Star

I typically don't copy posts from Facebook here but please be aware and someone tell me how this happens!

Well I was never very good at geometry but there is a thrust angle setting on the drive axle. I have been told that if not set properly the rear of coach crab walks and tag axle shifts trying to get it going straight. Spartan say allowable shifting of tag axle is +/- 1”.

I’ve had my coach aligned by Spartan and still wore out right tag axle tire. I recently had Newmar alignment at service center and will say they explained every setting along with cause effect if out of spec. Time will tell if tag axle tire wears out.

BTW mine never looked that far out as FB post
