Transfer case select switch??

[HUMTECH]

Sounds like you might have a broken front cv joint and also sounds like the t-case will not shift to all wheel drive range. Could be internal t-case problem, encoder motor or switch.

I second Humtech...

Odds are the case binding caused the CV to fail.

I guess I'll take to the steelership today and see what they come up with.

Update!! my front CV joint feel apart about 100 yards from the steelership. They called and said it would be 1,200 to repace the front axle.WTF !! they were going to charge me $850 for just 1 front axle. I called the parts store and got one for $75. They want to charge me 1,900 to replace the rear diff. locking coil(they said thats why i have the service 4wd mess.) . This is why no one should ever go to a dealership to have there rig worked on. I DONT KNOW WHAT ELSE TO SAY !!!

Im a tech at a dealership and i know parts are quite pricey. In a situation like that i would quote the gm shaft and an aftermarket shaft and let the customer decide. Thing is with an aftermarket shaft you have no warranty on the labor side of things. But the price difference in this case makes it worth it to go aftermarket. I always suggest cardone shafts, they are bigger joints than oem and have had no problems with them. As for the coil in the rear diff, kinda stuck there as its a dealer only part. You can try gmpartsdirect for a price but its still about 4-5 hrs labour as the diff has to come apart to replace it.

They called today and now want to check my shift fork in the transfer case to make sure its working right. I'm going to take it in this week becouse i dont want to drive it in 4hi lock ( the dealership said it was in 4hi lock due to the sevrice 4wd light). when you turn the wheel sharp you can tell its in 4hi lock. The hummer only has 58k mile and this has been my only problem( i just want it fixed).

Yeah, better let them check it. When you drive on pavement with 4HI engaged and turn the wheel to lock, a tire, if not two, should 'skip' as the transfer case has locked the front and rear axle together to turn at the same speed so the outer tires will have to rotate more than the inside tires. I have an LSD in the rear, but an option is to replace it with a true locking axle to give you even more traction. Best of luck.
