SOURCE: hummer h2 transfer case

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.

I have a 1999 Polaris Ranger 6 x 6 what engages the front wheels transmission or front gear box

I'm in the UK and not familiar with your particular vehicle..
However, the front gearbox as you call it is probably a transfer unit/case. This transfer case takes power from your auto transmission and transfers it to the front wheels.

You can remove the front propshaft (drive shaft) from the transfer case/front differential and make your vehicle 2 wheel drive. This, supposedly, gives you better mpg.

I have a honda TRX 350 2000 model quad and the 4wd is not working, any ideas?

Your 4 wheel drive may be working, but it is a torque-sensing front
differential for reduced steering effort, that supposedly sends power to the wheel with the most traction. Many owners have found that just the opposite is true. Your problem may mean that the differential is working, but because it doesn't lock up both tires in the front and only one tire is getting all the traction you can't see it work as advertised. The link to the video is great for showing what may be happening. The front differential may be worn out and need to be fixed or it may just be that it is not working as you expected:

I have a 2002 Polaris Ranger 500 the 4x4 button

There is a big serrated washer that engages the plastic cogs to make the 4wd work.Either the magnet is not pulling in the washer or your white plastic cogs are broken.I have had my 2005 700 apart.If you are mechanically inclined it will take a a good 1.5 hrs to get it all apart to inspect it.
