My rear ARB is playing silly bu99ers
It has developed an intermittent leak. I replumbed the plastic tube and redid the diff connection with a new olive. Sitting on the drive all worked fine - compressor primed fine then shut off, diff lock operated correctly with the compressor topping itself up as necessary after a few on-offs of the diff lock.
Take a trip off road (well, Slindon actually ) and the damn thing starts playing up - with the compressor primed and ready to go I switch on the diff and the compressor runs incessantly . A bit later in the day and it all works fine, a bit later on its leaking again
It became such a problem that I actually drove all afternoon at Slindon with the rear diff locked for fear of not being able to lock it again! Made for some interesting 57 point turns I can tell you!
The leak is obviously between the compressor and the diff and as it is only intermttent I think it is the diff connection and is dependant on the axle position (Although once it was enganged, the compressor didn't kick back in at all, despite using full axle travel.)
Can anyone shed any light on this? If the olive is new, what else in the connection can cause this kind of problem?
