jcb 520/4 farmspecial loadall. front o/side wheel stalls and learches while driving in 2 or 4 wheel drive in forward or reverse all other wheels seem to be ok. machine is a 1985.
any suggestions thanks.
the axel has inboard hydraulic brakes so i dont think its any thing to do with the brakes and if the diff was damaged it would occur on both front wheels.

I presume that the axle is of the bullgear type with external brakes .Either the brakes are locking up, the sun and planet gears inside the diff are breaking up or a wheel bearing has broken up and locking the drive.
