I'm not hiding, I'm in Calgary AB Canada. I assume you work as a mechanic, or in the Auto industry if you have changed 2 or 3 of them. I'm not trying to argue with you and I appreciate your input. I'm not in the auto industry at all, so there's no doubt that you would be more knowledgeable and aware of problematic components. I know clutches are a wear item that will eventually fail, but under 120 miles would have to be severe abuse. I think the Auto transfer case works great and should last a long time if used properly. Just out curiosity, do you know what kind of cost to replace the clutches?

My Quote didn't need to be fixed. The transfer case was designed by an engineer not marketed. Driving in 4x4 in mixed conditions can be very stressful on certain components, especially in tight turning situations (parking lots). This is my third GM/Chev truck with Auto, I live in Canada and drive in Auto quit often during the winter months. I have never had an issue. Everyone I know that has Auto does the same and none of them have had problems either. How can you compare driving in Auto to driving with brakes at 20%? Just because one guy you know had a problem doesn't mean it's a bad system and people shouldn't use it.

I'm no expert, but I doubt that very much I don't think you can wear out the clutches in 120 miles unless you were purposely trying to destroy it or abuse it. I have heard of people leaving there trucks in Auto for the entire ownership of the vehicle (over 100 thousand miles) with no problems whatsoever. I definitely wouldn't recommend that either, but if you drive your truck properly it is completely fine to drive in Auto in mixed conditions. That's exactly what it is designed for. Try to remember to turn back to 2wd when dry condition.

My biggest issue with the factory Rancho shocks is the rebound. I feel like the compression stroke is okay for a factory 4x4 suspension but the rebound seams to have no control whatsoever. A good shock should control the compression and rebound stroke. I haven't replaced them yet but hopefully soon.

Is your wheel making contact or the tire? My brother in law and I both have All Terrain Sierras, with stock GM 20" wheels. Mine is still stock setup but he put a leveling kit on his, but still has the stock tires. When I was looking at his setup we noticed that his wheels not the tires are now rubbing on the upper control arms. The inside edge of his wheels are worn down to a sharp edge compared to my wheels. I'm not sure what brand or height level kit he has on, but I'm guessing the angle change was enough to make contact with the wheels. I have searched on this site and on Google, but haven't found anyone with same problem.
