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.

There is a solenoid on your transfer case that is used to shift from 2WD to 4WD. It may have frozen or is just stuck. If you know what to look for, get underneath the vehicle, find the transfer case and locate the shift cylinder. There is an electrical connection on the shift cylinder. Ensure that it is plugged in.

try putting it in 4wd and go forwards a few feet and then put it back in 2wd then backup a few feen and stop and see what happens.

If you can`t find your spark plug`s on a basic (V8orV6) you better take your HUMMER to a mechnic to have the work done

when driving in 4wd engagement there is a problem in that the torque in the axles and drive lines is not dissipated on hard surfaces as the wheels cannot slip ( great for snow ice mud gravel and the like but a no-no on hard non slip surfaces
yes reversing it will relieve it but if on hard surface ,winds it up again in reverse
better to simply drive two wheels onto the grass verge of the hard surface and then kick it into 2wd
if the diffs are limited slip diffs then the antislip action in the diffs will be pressed very hard together and will produce problems on turning corners
you may have success if you get all 4 wheels of the ground on a hoist and let the wheels spin and then try to engage 2wd

not as easy, but possible.. the best ones to tow are a wrangler or any saturn car,or suv..good luck keith...
