SOURCE: can not remove rear axle on chevy avalanche 4x4 1500.

you will need to take off the differential cover (drain and change diff oil at this time)

rotate the axle so that you can get at the cross pin and remove it by undoing a small bolt that holds it in place. it should slide out with ease, but i have had them stick, take care not to let the cross pin get lodged where it is difficult to extract

a single C-clip is holding each axle inside the differential housing

you will need to push in from the outer end of the axle, while simultaneously manipulating the C-clip off of the inner axle, repeat this same process on the other side

i will put some of pics up in a minute

If it was front U-joints, you would have gotten under there
& checked them, before you came here,not ask us for a

I would say check scan tool data for the transfer case,
then work on that issue

May have a failed encoder motor

pulg in the motor, put the switch on 2wd and then try to in stall it alot of time they can be a pain to put back in. you have to make shur that the motor and gear same location. if your transfer is in 2wd and the motor is in 4wd it wont slide in place motor 2wd transfer 2wd should slide in.

You can hear 4x4 engage when you press 4 hi or 4 lo and light does come on the indicate but you cannot move in any amount of snow. there is no extra gripping power. its just like in 2 wheel drive. what...

i had a similar problem with mine, check to see if you are getting vacuum to the front 4x4 actuator valve under the battery tray, it looks like a big diaphragm with a cable hooked to it. the hose is tied close to the oil dipstick. if the diaphragm sucks in when you have the vehicle started and engage 4x4, then its likely front axle related. but if you get no vacuum at all then check the vacuum pump located on the transfer case. i didnt have the money to replace the vacuum pump so i made me a turn valve under the hood and ran vacuum lines to the intake. just make sure you turn the valve off after you disengage 4x4 or you will use more gas cause the front axle would stay locked in, and may cause more probs down the road. the vacuum pump on the transfer case is about 200 bucks. it cost me 10 dollars for the valves and hoses... hopes this helps.

4x4 indicator flashing all the time wnen not engaged

2001 Mitsubishi MONTERO 01 - Transfer Case > POWER TRAIN : TRANSFER CASE (4-WHEEL DRIVE) [Part 104000 ]
TSB No: 0223007 NHTSA ID: , November 01, 2002 : Replacement:
Summary: 4wd indicator lamp flashing / diagnostic trouble code (dtc) 33.

2001-02 Montero
A flashing 4WD indicator lamp and/or DTC 33 may be caused by corroded transfer case shift position switches. The original switches are susceptible to water damage, and new revised switches are available to prevent the problem.


1. Replace the five transfer switches

2. Clear the DTC, using the scan tool.

3. Test drive the vehicle to confirm the 4WD indicator lamp does not flash and DTC 33 does not reset.
