There's something seriously wrong in the transfer case or controls. It seems the rear driveshaft is locked up, and the front wheels are driving. The driver's side rear tire is skidding because it's trying to turn backward - rear passenger rear tire is going forward and rear differential has no option but to turn the driver tire in reverse (driveshaft locked). DON'T TRY TO DRIVE IT. Get it checked out and fixed.
With the older drum brake system going in reverse will often tighten the adjuster on the brake mechanism. The adjuster has a thumb wheel to adjust the shoes in and out. BUT there should be a little plate that locks the thumb wheel once you are where you want it to be. I would guess that either you don't have that little plate or it is not keeping that thumb wheel from turning on the right side.
take a standard screwdriver apply pressure to the whole switch panel towrds the drivers window then repeatedly push the 2 wheel drive button until the low lock button flashes then keep on pushing 2wheel drive button til it shifts you can tell its out by cranking steering wheel all the way to either end of travel and move foward no binding means your out
Your truck is equipped with RWAL or rear wheel anti-lock. This just worked on the rear brakes(duh) but the speed sensor was taken from the speedometer drive at the transmission tailshaft, and would allow one rear wheel to lock as long as the speedo kept turning. Later models were improved with wheel speed sensors at each wheel.
Remove wheel from drum... using a large hammer crack the wheel drum a few times, this should loosen the brake shoe's or the rust which is locking the drum, on the rear of the drum you will find a small square nut which is the adjuster for the shoes try to turn anti clockwise this will also help to loosen the shoes.... hope this helps
well i had the same problem everyone told me the clutches in the rearend were sticking making it stick in positive traction (only your passanger side rear wheel pulls unless you start spinning then a type of clutch engages the other side so you have traction then when you stop spinning it disengages it should never be engaged if your on pavment) now you can do what i did listen to everyone when they tell you its normal or you can take it to someone with experience now and save yourself some money cause it will start popping then it will get some viberation then next it will break the clutches and when that happens you will have to replace the pinion,ring,and the spider gears as well as the clutches.make sure you have pleanty oil in rearend if you dont add the limited slip conditioner it might free clutches up but if i had it to do over id put it in the shop or stop driving it before i broke something hope this helped
If no oil on the driver side, you have a locked up parking brake pivot. Follow the park brake cable to the inside plate of the rear wheels. on the outside, where the cable connects, look to see the position of the visible mechanism connected to the cable. It probably will not match the side that is not locked up. This is a very common problem; you need to replace the park brake pivot. Additionally, you are going to need to remove the other side axle shaft and get the leaking oil seal replaced. Replace the brake shoes if they have oil on them.
