How do you remove the front differential on a 2008 hummer h2?

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.

Seal all the lights on top. Mine flooded from the water running down the light harness wires. Used clear rtv sealant and fixed it. You will have to remove the seal the two larger lights on the corners.

I have the same vehicle and was able to remove mine with the following steps: 1) remove light behind each rear of luggage rack rail using phillips screwdriver (one screw each side). 2) remove molding underneath each light using T20 torx driver (2 screws each side). 3) Loosen cross rails nobs. 4) Side cross rails off of roof.

1 of 2 things are going on, either the brake light switch is malfunctioning or the solenoid in the shifter assembly. when you apply the brake, you should hear a light click in the centre console allowing the shifter to release. if this is not heard, inspect the fuse block for burned fuses(unlikely but possible). next make sure your brake lights are working. if they are working it is perhaps the solenoid in the console itself. sometimes a little wd-40 works. but you need to get to it directly.
