  1. Done some work on the truck today removed the breathers for the axles and found them to be well and truly blocked (hard), now if I am thinking correctly this would not have relieved the pressure in the axles after/during a run and therefore the pressure would release from the weakest point which would be the seals.

     

    Am I thinking straight. :dunno:

  2. Hi Folks

    Since bringing the jimmy home I have developed a leak on the middle axle, the oil seems to be running out from between the wheels and over the outer tyre and it is parked on a slight slope towards that side, now when I had the Reo one axle leaked like this until I cleaned the breather nipple on top of the axle as it was not releasing the build up of pressure?

     

    My question is, could this be the problem here or could the seal have gone and are they hard to change, I have seal kits so that is not a problem assuming they are the same for all axles on the truck.

     

    Any ideas please.

     

    regards

  5. Ok thanks fella's mind is made up, I have just looked on the CCKW site and in 90% of the pictures they have the extra nuts on as well, so that is what I am going to do, plus it will not hurt to go that route.

     

    Regards

  6. Mike I do not envisage ever having to put double wheels up front (I only have one spare) so as it is now it might be wise to put the extra nuts on and be doubly sure that they are safe :dunno:

     

    It's a thought
