Do any of you with a 1210/1310 Dana 60/RA17 have any problems with the axle shaft seal leaking? I use a National 455008 and battle this problem quite a bit on my two trucks. There is no perceptible groove on the spindle sealing surface. Maybe a CR 26921 is a better seal? When they leak, my brake shoes get soaked in 90 weight and that heavy drum/hub is challenging for an old man to R & R. I put a bit of sealant on the seal OD and try to be careful sliding the hub assembly in place over the spindle. Thanks Edit: That reminds me I need to check my vent/breather to make sure it is clear.
