In order to replace the seals, remove the front diff assembly. To remove the passenger side seal, I would suggest removing the tube assembly (5 bolts). This is due to a steel washer that goes on the end of the axle. If you just pop the axle out, it is tough to get the washer aligned and back on the shaft. Use anerobic sealer to seal the housing to the diff case. The drivers side you can pop out with a hammer.

What is the correct part name for the front side of the rear end cover & gasket/seal?


i assume that you are talking about the seal at the front of the differential were the drive shaft bolts to the flange,if so this is called the front differential pinion seal,if your talking about the differential cover at the back of the differential(most rearward part of the rear end) this is called the differential cover gasket.

Front wheels won't engage when in 4 wheel


Then the problem would be in the differential. something came loose or broke off the actuator on the inside

To change a front differential, do you have to take it all apart.... it's for a GM serria 2000


Yes, many components, such as the front stub shafts, the front wheel hubs, certain steering linkages etc. must be removed. Then you've got to open the differential cover and use a special "spreader" tool to actually remove the differential. This takes quite a bit of experience, Good luck, Dana

Transfer case engages , but the front differential doesn't


There is an actuator motor on the front axle, to the right of the center section that locks the front axle. With the ignition on and the transfer case in 4whl drive check that the two wires at the actuator motor have a power and ground. If it does then the motor is likely bad. They aren't too expensive. Runs around $270 from GM, but can be had for under $100 aftermarket. They are easy to install, disconnect the electrical connector and unscrew it from the axle housing.
This is what you'll be looking for.

This is an image of the early design. The new design is mostly plastic and doesn't have the wires attached. I'm not 100% sure which design your vehicle has.

Had 2001 GMC Sierra in 4WD Auto and went to put in 4 hi. then Service 4WD light came on and selector wouldn't let me select anything and the truck stayed in 2 hi.


On the full size, the front actuator is electric, not vacuum.

When in 4wd mode, a switch on top of the transfer case conducts 12 volts out to the actuator. Wire #50 (brown) is the 12v feed, and it conducts to the light blue wire (#900) to the actuator.
When shifted out of 4wd, the switch opens up and no voltage goes to the actuator.

Check voltage at the connector for the front actuator (at the front differential - it looks like a large bullet that threads into the front diff.) If it has 12 volts, the actuator is the problem. If it does not have 12 volts, check the transfer case switch and the power feed to the transfer case.

I'll assume it is the actuator, if the plug to the actuator is getting 12 volts when in 4wd.
The way this actuator works, is it is a sealed chamber that gets heated by voltage. When it heats, the pin in the end swells and pushes a shift fork in the front differential. The shift fork engages a spline on the passenger side of the differential, and boom! you have 4WD.

GM offered an upgrade to this actuator that is a motor instead of a heated device. However, it requires a small harness addition, a spacer, and a new actuator. It is about a $150 to $200 option.

Good luck. The actuator is usually the problem 90% of time but recheck all of the wire harness just to maker sure there is no short before replacing any parts.

1996 Yukon 4X4 Electronic Shift on Fly.


I had the same problem with the shift on the fly push-button 4x4 on my 97 Suburban. GM Shop manual indicates that it could be due to an encoder error on the actuator motor. Try pulling the transfer case fuse to reset the transfer case control module. Wait at least one minute. Re-install fuse then re-try operation. Did it last week and that saved me a trip to the dealership and extensive troubleshooting.
