Yeah, I do the same with my truck...well, cuz mine doesn't have auto for one, just 4 hi or lo or 2. But yeah, good tires and the LSD rear is fine. My Pacifica has an option to turn off the ESP (electronic skid protection) but this Rainier has NOTHING. No switch for 4 hi or lo or AWD or anything, and no switch to turn off AWD completely like my Pacifica. My understanding is the Trailblazers and Envoys have a selection but Rainier and Bravada do not.

Same clicking happens, cuz I did try that, but not to rule out the the hub...a buddy told me that the CV axle shoudl wear out before diff does, so even with high doubts that the axle itself was bad, I bought one and tried it. I guess I should add that on the jack stands, the front drive shaft rotates when running in gear, but the CV axles do not...obviously the computer doesn't think the rear wheels are slipping.

Cuz it doesn't appear to just "drop" out, it looks like the undercradle is in the way and may need dropped, or motor mounts released and motor lifted and shoved over a bit.

Is there not an edit option like most other forums?? or am I just blind?

Anyway, just to clarify, I don't think there is anything wrong with the functionality of the vehicle, it is just a hum like a wheel bearing while driving, but a clanky chatter type sound when up on jack stands.

Sorry, regular members do not have the option of editing posts. We would rather have you make another post to "correct" the previous message as oppose to making the correction in the original post and people not notice it. Especially in the technical threads.

Ah, ok, its fine, just that most forums I frequent they get irritated for making a bunch of posts because of errors or afterthoughts then hound you for trolling to up your post count...I guess it just a difference of the typical communities.

Hm, well, this Rainier has a disconnect, and no selection switch what so ever, so it'* gotta be AWD. Maybe the reference was to original AWD where literally all wheels drove, where as this is a traction control AWD, so it has a disconnect. Not sure.
