Looking to see if anyone has some suggestions while I'm stuck in the snow up in Tahoe, 60 miles from a Hummer dealer who won't be open until Monday...
Tried pulling out in the snow this morning with the H2 and the was basically getting no traction. Finally got the thing moving with a push and found that trying to switch from 4HI/lock to 4HI/unlock results in a lot of mechanical noise and then loses all power.
Shifting back to 4HI/lock stops all the grinding noise, but it appears that power is only going to the rear tires. You can see the front wheel shafts rotating, but the hubs don't appear to be locking. Shifting to 4LO seems to have the same result.
Anyone have a suggestion for trying to get the hubs to lock in the front? I've abandoned the H2 for the night, but would like to try to get it moving in the morning and it won't make it too far in the current conditions on 2 wheel drive.
- Ain <HR></BLOCKQUOTE>The H2 is full time 4 wheel drive, there are no locking/unlocking hubs. There is some normal mechanical noise when switching from high to low as the transfer case switches. The difference between 4hi lock and unlock is that locked simply means a true 50/50 power split front to rear but even in unlock there is power to the front, it's just not locked at 50/50.
Do the words Traction Control come up on the DIC when you are spinning the tires? Where are you seeing shafts turning?
