Only way for this to happen on an H2 (AWD) is for something to break rearward of the lockup hub. Take a look at the splines between the intermediate shaft and centerdifferential or even the teeth on the forward sun gear and/or stepped pinion on the center diff.

As long as you have the t-case torn down for repair be sure to upgrade to the new aluminum mode fork (production upgrade to old plastic forks thru end of 2007 or so). You should also upgrade the rear half of the housing to the 2008 version which has a pressed-in rear prop bushing (better bushing and is also replaceable.

2005 h2 hummer getting messages to service 4 wheel drive now at about 25-30 mph getting a vibration


First check the drive shafts(vibration). Universal joints could be bad. Best to have it off the ground. No pressure from the tires and transfer case/transmission. Service 4x4 has to go on a scanner to get codes. Check fuses first.

1990 GMC suburban actuator and fuse location. There is not one on front differential and no place for fuse in fuse block. 4 wheel will not engage. No owners manual


The actuator will not be on the front differential or drive line, it will be on the transfer case, which is mounted behind the transmission. Follow the front drive shaft back from the front differential, and the component at the rear of the driveshaft is the transfer case. That is where four wheel drive is engaged/disengaged.
I'm not familiar with your vehicle, but if you have a separate lever to engage 4wd, there will not be a fuse for the actuator - it is a manual system. If the 4wd is selected electrically, check that all wiring and connectors on the transfer case are in good condition.

What is it that engages front drive. Is it front gear box or in transmission?


Depends on what sort of set up you have.

If there's a transfer case - it's like another gearbox on the transmission - it's the transfer case (I.e a gearbox..) that supplies power to your front wheels.

The transfer case is itself powered by the transmission. You will have a propshaft (driveshaft) running from the transfer case to the front differential.

Can 4 wheel & differential be used together


If you have four wheel drive engaged, engine power is routed through the transmission to the transfer case to the front and rear differentials. When four wheel drive is disengaged power goes only to the rear differential.

Make sure that the vacuum hose connector is connected AND connected correctly at the transfer case and at the front differential. If that is all right and the front differential still doesn't engage, then you need to test the vacuum actuator at the front differential.

Do you drive.in two wheel or four wheel drive, how do you change.to two wheel drive?


The Hummer H2 and H3 are both all time 4WD. There is no way to put it in 2WD. Now, you can select 4WD High or 4WD Low. You can also, if your vehicle is equipped with it, lock the front or rear wheels through the differential selector. This is one of the primary reasons Hummers get terrible gas mileage is because they are always in 4WD.
The only other solution is to swap the transmission to an Allison 6Spd, which is often done with diesel conversions, and they usually give you a 2WD option, and can get up to 25 MPG out of an H2.......but that conversion is about $30k.
