If the RWA axle on the R60 is similar to the L3, the most likely source of leaks will be the hydraulic swivel joints that direct oil from the axle housing into the RWA motors.
If you pull the wheel and covers off you can see which one is leaking. They can be rebuilt with new seals. The swivels used are not a good design as they only have a felt seal to stop chaff and dust reaching the pressure seals.
Any replacement swivels need to be exactly the same dimensions to allow the hoses to connect. I couldn't find anything to fit other than the expen$ive originals.
