Help! 03 chevy tahoe z71 troubleshooting

[Adrian M]

Wife took the truck to get new tires and she knocked it into "auto 4wd" and I noticed it a day after.. Now it has a rough sound and feel coming from the back.. Where do I start? 

[Adrian M]

It was drove in auto 4wd in dry hot conditions and up to 60 miles per hour for a few miles.. I hope the rear transfer case isn't damaged..

its unlikely auto 4wd did anything and i would be thinking more about an out of balance wheel first

[Adrian M]

just had a new set of mud terrains put on the truck.. It mostly feels rough at low speed, starting and stopping and reverse.. You think it thrown a weight off?... Thx for your reply 

[evad]

could be ...or maybe just a bad balance job...or a bad tire

[evad]

rotate wheels and see if any thing changes

[Adrian M]

Ok thx..

If they are mud tires, that's the way they are going to be. They have a big nobby tread pattern.

I was thinking that was possible too.. I guess I wanted to make sure I wasn't completely crazy
