auto locking hubs???

[goodino5x]

whats the protocol for greasing the auto locking hubs? 96 with 135000, and when i engage the 4 wheel it has a slight popping sound. truck sat for a good year and a half before i got it. think this will help? thx

If i had time i'd find it for u but google "Guzzles "

it should come up

I'd bet that the popping sound is coming from the double cardan u-joint just off the transfer case. If I was a betting man, I'd count on replacing the two u-joints and the yoke. That's what I had to do.

I disassemble my hubs and lube them with a light grease. I would be willing to bet your axle shaft u-joints need replaced.
