Bill, the manual says not over 55MPH during the first 500 miles, slow down, you said before you were doing 85MPH and had Hummer for 3 days. I don't know how you can drive 55MPH in a Hummer on the freeway, even grandma in a Yugo will laugh at you. I did not read that part until after 200 miles, I did freeway at 75 MPH. Better safe than sorry.
Did they tell you what, why, how the transfer case cracked? or just a defective part? Very interested to know.
