I have a 2006 H3, with around 65,000 miles. I bought it from the original owner 6 months ago. It snowed pretty good this winter and I pushed the 4H-lock and it worked like a charm, plowing through the snow. Put it back in the 4H, and it worked like normal.... .... ..... that is until I went to park in a parking spot.... it jumped like it was still in 4wheel lock... So I re-engaged and disingaged the 4Hlock... tried reversing it for 1/10 mile.... lol... Had my local mechanic put it up on the lift and he said.... the 4h and 4hlock are engaging and disengaging properly.... but he agrees that it hops when in a turn on the ground..... Any advice? I hate to take it to a Hummer mechanic and spend $120 hr for them to drive it all day?
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

Hello marcampbell2, your escudo should be in 4H for highway use,the N position is used for towing purposes.take care and drive safe

First, check the transfer case and make sure it's full.
If you have the electric shift system in your vehicle, a servo motor could be failing, or the switch may be going bad. Even the switches on these systems are expensive so good, accurate testing must be done to verify failure of anything before you start replacing stuff. If it's not electric, check linkage to transfer case... something may be loose and sliding out of adjustment. Todays systems are just too complex to give accurate answers without hands-on testing. Many times several different items can give similar symptoms. That is why most shops say "bring it in and we will look at it".
good luck

It doesn't take long to learn when and how to use your
truck's 4WD system. Follow these steps and you'll feel confident about
engaging the system the next time you need to get out of a slippery
situation.
For a conventional system, where you can select 2WD or 4WD, the
instructions refer to engaging 4WD. For trucks with permanent 4WD, they
refer to locking the center differential.

My 2006 Hummer H3 is not coming out of lock position. Indicator light says its in the normal 4 wheel drive but it doesn't feel like that when i am making a hard turn. I tried driving in reverse as well as letting it sit in the garage overnight. What is prob?

I also have a 2006 H3 doing the same thing. It started at 49,000 miles and I ignored it at first because it only did it once or twice a month. Now that it has 59,000 miles, happens all the time when I turn or park. I am seeking a mechanic who can fix.
Just talked with the Fix Ya tech "chat live now" option for $20. Just couldn't wait... turned out there is a recall out on this problem. Said a GM dealership would fix it no charge and even gave me the bulletin number so the dealership would fix it right right away! wahoo!!! thanks fixya dot come!
I have the same issue do yu have the recall information?
I aslo have the same problem mine is a 06 with 55000 miles, when you turn the wheel it pops and jerks really loud, it also has a little popping noise when driving in the same wheel (it sounds like the right front) even when not turning the wheel don't know if this is the same problem, been trying to get it into the dealer where I bought it but I can't for a week or two I bought it used at a dodge dearlership hopefully the extended warranty covers this.
