Disco 2 Amigos after off roading

I have managed to activate the three amigos again after going off road. The problem appears to be an electrical failure on the front left and an erratic reading on the front right. Is this possibly due to mud getting into the gubbings?
I have done the shuttle valve repair and replaced the left hand abs sensor with a new part. The right hand sensor has never caused me a problem ever prior to this reading.
Any help welcome. Thanks in advance.

Not sure you'll get away with replacing the sensor. Usual opinion is to change the hub in one unit (I've done 5!!)

OK developments. Put the code reader on and as driving the car the right hand side wheel buckled. Im hoping it is a broken bolt. Could it be a snapped axle?

More likely a wheel bearing.

Thanks all. Car recovered and it looks as if it is the hub that has gone. Towed to garage for a fix.
