Just had new brakes on my 84 Longbed Deluxe 4x4. 89k and original owner.
Got stuck big time in mud.  Hubs locked in fine, and after an hour of
shoveling, was out.
Spun hubs to free and away I went. Drove home 70 miles at 60-65 mph.
Decided to play it safe and attempted to lock them in a couple days ago
when I was confronted with another mud hole.  Drivers side locked in
fine, passenger side stopped about half way between free and lock. No
amount of backing and forward motion would help.  Made it through the
mud without 4 wheel drive, but wonder if it was something I'd done
previously or the tech may have put something back together incorrectly.

Ideas please.

Thanks
Mark
