Make sure ebrake isnt applied first... then with the vehicle jacked up see if the wheels turn... then since they dont you need to make sure its either the ebrake system or the rear brakes arent locked up which could be the rubber hose going from the chassis to the read end... this will get you started. let us know

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

SOURCE: Transfer case leak

You mean between the case halves? It is just silicon, no gasket. These are good for the pump wearing a hole in the rear housing and leaking oil. The cure for it is a new rear housing and a piece called a case saver that keeps the pump from doing it again. Taking the transfer case apart to fix it is easy, I can tell you how to do it.

SOURCE: car wont roll forward or back even in neutral

I assume it's a manual transmission.
If the car will not roll backward or forward in neutral (with or without the clutch engaged) the transmission is most likely locked in two gears at the same time.
This may happen if gear selectors are excessively worn. If you are able to examine the gear selection levers external to the gearbox, ensure they are in the 'neutral' (no gear selected) position when the gear lever is in Neutral. If not in correct position, you may be able to manually reset the levers to correct neutral position and thereby unlock the gearbox.
In any case, if it's happened once, it will happen again, so get the gearbox and gear selection mechanism checked for wear or breakage.

2007 Chevy Avalanche 3rd and 4th gear are not working


From what you are describing, it is possible either the 3-4 actuator is no longer playing with the 3rd & 4th clutch packs, only way to know for certain is to hook up the good ol' pressure gauge to trans. system, yeah, you think the Chevrolet dealer should know this right?

Sell it now if you can!
