JCB TLT30D 4 X 4

We have a JCB TLT30D 4 X 4 which keeps locking up the front r/h wheel when being driven. Its not the wheel motor at fault as its been stripped and inspected.
I seems to be ok when driven very slowly but when you drive fast it locks to the point of stalling the engine.
You can get it to stop doing it if you disconnect the l/h anti slip valve solenoid.
I think it is something to do with one of the wheel slip sensors, wiring or transmission controller but I am just looking for any pointers before swapping parts or ordering new?
Any help will be greatly appreciated.

Hi danny, I'm quite familiar with these so may be able to help.

Had a tlt 4x4 do this to me about 6 years ago with a n/s rear wheel. First thing to do is check the wiring loom to the wheel speed sensor, the loom is protected by flexible convaluted conduit that can appear undamaged but if it's had a whack can crush the wires - this I have found has been the cause of 80% of the faults on the 4x4 system. Speed sensor is next possibility.

Have you checked both susmic controllers for fault codes? The red status light flashes morse code if an error is detected. One is behind footwell panel in the cab - this is the main controller, the other is under the cab in the engine bay where the seats bolted - this is the 4x4 controller
