Diagram of 4wheel fron axle on a 2001 blazer

Go the a Chevy dealership parts dept and get them to print it for you.

Go to You Tube Video & see where the fill plug is

Watch people changing their rear axle fluids on a
2001 blazer

Axle nut preload is very important, too tight will cause premature wear of the hub. The proper preload for a 2001 Chevy Blazer is 103 foot pounds.

most axles fill plugs are located on the rear cover just fill until it starts coming out and your done. on some axles there will be a plug on the axle itself located on the fron side of the housing close to the driveline

What is wrong with it? Doesn't engage axle,leaks ,drive axles,hub bearings?

the front differential has a vacuum actuator on it. check to see if the vac. hoses are connected to it.you may need an actuator.

If there is no switch present then it is full time 4X4, it does not disengage, good for travel bad for fuel mileage.

i dont have a picture but its really simple once u get the rotor off,if i remember right these are one piece shoes,and there is i little clip that holds them against the backing plate,simply slide them out of the clip and the open end should slide off the adjuster at that point then just simply slide the open end of the shoe over the thinest part of the axle in front of the axle seal and just reverse for insall,hope this helps

autozone sites has free diagrams,look online. or go to a napa store and theyll print for you. that sensor is the only 2 wire plug in the trans harness. it should be on the output of the transfer case

3 bolts from the back, axle nut and take the caliper off pretty easy.
