4x4 not working

Was the bearing the root issue or was the absence of oil the root issue?

 

Lack of Oil caused everything….:/

 

My thing is how can you monitor front diff oil levels?

 

You shouldn’t have too. It’s a more or less sealed unit. Was it not making a lot of noise before failure?

I’ve lived through 2 diff failures and both were preceded by a loud howling. Caveat: the 2nd time i saved it before total failure.

 

Checking the under vehicle fluids every oil change is part of the multi-point inspection along with inspecting for any evidence of leakage.

Daily you should monitor for wet spots where you park just as a matter of routine.

 

Not that I noticed.
