I'm aware of the issues with the GMT900 driveshafts that like to fail/pancake out at
higher speeds... (from what I've read, anything over 95 mph for a short distance)
Obviously we don't drive race vehicles. But I do tow heavy and when not towing have
gone a tad over the speed limit at times.
Anyway... Is there a difference from year to year ?? Mine is a 14 (last year of gmt900)
My driveshaft - REAR is made of steel and about 3.75" outer diameter. And I'm sure
it's the longest of the AWD/4WD since I have an XL model.
Of course a 2WD would have a longer one.
Let me know of info that you might have. I'm thinking I need to upgrade my shaft ! Just
don't know which way to go or IF needed for sure for my year.
