If anyone can help, I would greatly appriciate it. Here's my dilema, I bought a 87 Bronco last year with auto locking hubs, 4x4 worked great. I went off roading in the snow today for the first time since last year and got stuck due to 4x4 not operating properly can anyone send me in the right direction to help diagnosis this issue.........thx in advance

 

sounds like your auto locking hubs sometime you can disassemble them and clean and oil and will be OK lots of times people grease them with a heavy lubricant and that makes them fail to function properly if every thing looks good when apart reassemble with lightweight motor oil i use synthetic myself
