After going off roading this weekend, i have noticed a strange thing happening. Every time i have the wheel turned all the to either side, it wont move (on its own) and i dont know what the deal is. Especially when im backing up. Whenever the wheel is turned, its like it locks up and when i give it gas, it moves but the wheels hop. I cannot figure out the the problem is. Is it maybe a sticky caliper? is it stuck in 4wd (but the buttons show that it is not)? Any ideas or suggestions will be HIGHLY appreciated. Thanks!

BTW- While mudding i pulled out my buddy's jeep that has mud terrains on it and mine has street tires

here are some pics











the jeep i pulled out

 

you're in lock mode, 4hi lock.
if the h3 thinks its not in lock, the shift fork stuff may be busted

 

I agree with drtom

 

Not sure what tom said (have him blocked), but there may be an issue with your H3 being in 4HI Lock. There are several reasons for this.
1. The button on the dash is stuck (had this happen)
2. The T-case shift actuator is malfunctioning (2 buddies have had this happen)
3. The shift fork in your T-case is broken (many 06 H3s have had this issue, 3 that I personally know of)
4. There may be other reasons but these are the only experiences I have had with a T-case stuck in 4HI lock or 4LO Lock.

 

Thanks for the suggestions. After reading and researching seem like my tcase fork melted. Looks like in gonna upgrade to a metal one. Thanks again fellas.

 

Glad you got it resolved.

I love the pics!! Our best friends (wife and I) have Jeeps (his and hers). We tease each other back and forth so I can't wait to forward these pics to them! I promised them I'd never put anything derogatory about Jeeps on any of our Hummers, but I never said I wouldn't send them pics that tell the whole story!

Thanks again and good luck with your repair.

 

ok on the fork, now, u do know its always in 4wd huh? 4hi is all open diffs,jfwiw.

 

By all means, if you have to replace the plastic shift fork then it would be foolish not to upgrade to the later fork at this time. A knowlegeable repair shop will probably already be ordering you the newer shift fork but it never hurts to remind them first. The new part is GM Part # 1918 0438. Check out this thread on the shift fork and replacement:

I do know it is awd yes. 4hi lock is what I meant.

Thanks for the info. Once I narrowed it down to the shift fork, I googled it and this thread showed up. Thanks again.

 

i always get teased about having an H3 people saying it sucks and not made for off road, soccer mom vehicle, blah blah blah. I thought it was funny i had to pull him out
