4wd Question

[333pppp]

Hey guys, i was just out trail riding in my 86 1009 and i believe my 4wd is not working. the front tires will fling mud at times but under a heavy load they Just sit still while the back wheels spin. Any ideas why it would only work some of the time?

Thanks

At least one of your front wheels should be turning in 4wd. If not, you may have a broken axle in the front.

are both your hubs "locked"?

Yeah they are locked and the front driveshaft turns

I'm willing to bet that the splines on your front driveshaft might be worn out. I had a 88 fullsize Jimmy that this hapened to. If the dust seal fails and you don;t lube the driveshaft regularly they wera thesplines out fast. If I held it in my hand it felt good, put a pipe wrench on it and try to spin it still felt ok..., but put it in 4WD under the weight of the truck.... nope. You can get decent used ones from salvage yards, just bring the old one with you.
