very very hard
Same as the rear.
No it will not, It is all different. Actually yes it will i have to correct you om that i have a 96 blazer same front diff as an s10 and 96 to 03 are the same i just put a 2000 front diff in mine
You have to remove the diff cover, then replace with new gasket and refill thru plug.
depends upon the truck, diffrent ratio's were used
The vacuum actuator is either in the fender or under the battery. The actually diff actuator is on the back/bottom of the front diff. Mine (2000 blazer) is under the battery. It sucks to get to. If you check the actuator and it doesn't move at all, check the vacuum, if it's not getting vacuum, check the switch on the top driver's side of the transfer case. It sends vacuum to the actuator. It has three vacuum hoses coming off of it. It costs fifteen dollars at autozone and usually greatly improves the performance of the acuator.
94 and up.
Under the front of the truck on the diff. or hog head,This is where the actuator is located it has two wires on it and screws into the diff. or hog head,You will need to unplug the wire connector and then unscrew the actuator and replace it.
Yes, undo the front one the the LHS then the RHS if neccisary. Broken mounts are normally caused by locked viscous diff.
Raise and support front of vehicle with proper jacks. Unbolt front of driveshaft from diff. Unbolt both axles from differential flanges. Disconnect wiring shift cable and vent hose. Support differential with floor jack. Remove bolts holding diff to the frame. Lower diff on jack. You may need to turn the steering one way or the other for clearance.
no.
No.
the front diff is part of the gearbox and the diff/gearbox oil is the same-there is a dipstick on the offside of the box near the bellhousing.
