Grinding from transmission or transfer case and loss of 2high

I was experiencing violent grinding from my transmission or transfercase when slipping the clutch every once in a while. The noise went away so I decided it was okay to off road. After pulling off the trail I tried to put the car in 2high and the car wouldn't move, so I was able to limp it home in 4high using the front wheels to drive the car. Does anyone know what the grinding is and how I could get 2high back?
(the car is a 1982 cj8 scrambler with a cj7 v8 swap)

Thank you all for your suggestions. I ended up taking it to a local shop and they believe I blew up the differential.

First off It would be good to know what type of tranny and transfer case you have in your Scrambler. You should fill out your profile when you get a chance.

Have you performed any type of troubleshooting? Check to make sure your shifter and transfer case linkage hasn't worked loose. Get under the Jeep with a strong flashlight and look for anything abnormal.

BTW.....Welcome to the Jeep Forum!

Good Luck............

To add to what Trapshooter said also list wheel and tire size at each corner (I have seen people wheel with different diameter tires = bad) - list any lift, type and height lifted = possible severe driveline angles. The list goes on but check basics like all fluids - transmission, transfer case & axles. You said you drove home with only the front tires/axles pulling the Jeep. How did you know there was no power to the ground on the rear tires/axles?

My guess is stock 2 piece rear axles with a spun hub on one side.

The only way to check for power to the rear wheels we could think of was spinning the tires on the dirt. I tried to get the tires to spin and only the front wheels spun. The rears seemed to just getting pulled by the fronts.

Could that also explain the grinding while driving?

To add to the things to check. Make sure your axle gear ratios are the same
