Rescently going off road my four wheel drive was having problems. When put into four wheel drive it will travel for about 10 feet then "pop", and the four wheel drive would stop working. It does work in reverse. I checked the huibs to see if that was the problem, but they look fine. My bro said its my transfer case, Any suggestions?

:wtf

Was the clunk sound your transfer case popping out of gear if so check your trans and motor mounts might be the problem. What kind of hubs do u have? If there automatic ditch them.

:stupid If you have the auto hubs, do the converstion first. For starters it's cheaper than having the transfer case worked on and it's definately a must seeing how auto hubs are junk anyways. Then if the problem presists then have the transfer case checked.

My hubs are manual. Nothing was the wrong with the hubs. I think i do need to check the motor and tranny mounts also, they sometimes clunk when i drive. The four wheel drive works fine in reverse.

Something doesn't add up... from having a 13-56 apart I can't think of anything that would cause it to work in reverse but not forward. The tranny output shaft turns the planetary gearset which turns the t-case mainshaft. A sliding collar engages the chain to drive the front tires, and none of those parts care what direction the motor is turning. How do you know the 4wd worked in reverse?
Most 13-56 shifting problems are due to worn or missing pads on the shift forks. If the pads get worn or fall off the shift forks won't engage the gears properly and they can pop out of gear.

Exactly. And it's not uncommon for these to wear to a point where they can kinda-sorta sometimes hold the gear in the planetary. I'm guessing putting it in reverse loads the drivetrain up in the opposite direction and makes that gear move back into the planetary *just enough*. You hear about stuff like this all the time, there's no telling exactly what will happen when those shift forks wear........the only predictable thing is that it will be unpredictable.

What, you're MIA for months and you're suddenly allowed to get online Xmas day???????

Well what can I say, Tabatha dumped me and moved out a month ago, and she has visitation rights with the dog over Christmas :wacko
So what else am I going to do but sit around drinking Jimmy Beam and spouting off sh*t on the internet.... :rockon

I know it is working in reverse because when it first happened I was in the snow, and I was getting great traction in reverse, and it also didnt "pop" in reverse at all.

What am I looking at replacing?

I was there, and also saw that all 4 tires would spin out in reverse.

Well since you are goign to have to open it up anyway you might as well just rebuild it. Ass-uming the chain is not stretched too much, a bearing kit and new shift fork pads (along with a new plastic speedo gear drive and some other odds and ends) should get you back in business. There is not much too the inside of a 13-56 so rebuilding one isn't too big a deal. It would also be a good chance to check out the pump boss on the case and make sure it isn't worn. Keith L used to have some pretty good pics of his 13-56 rebuild on SuperFord, but who knows if they lost them or not.

Cool, thanks for the replies, I plan on re-gearing to 4.56, and putting quick lok's front and rear next weekend. I will take a look at it then.
