Thread: GREASED OR OILED WHEEL BEARINGS

Oiled or greased, water etc needs to be kept out. Stub axle seal surfaces need to be immaculate, and the correct RTC3511 seals used and then all should bve well Still need to be checked after deep water etc.

my whole set up is like brand new now with swivel hub and wheel bearings and axles fully rebuilt with kits i bought from coffs harbour 4x4 and with the amount of $$ so far i cant help but semi pull down and clean etc after any run but for the big run being planned to the cape i have to know what my chances are of a mech failure thanks to my changes

the oiled setup is easier to check and clean up later if something goes west.

Should easily cope with that trip, just don't overload the vehicle, and don't be in a hurry.

On bigger angles isn't there a chance of the high side bearings suffering from oil starvation??

And is it as simple as putting in new bearings and just not installing the oil seals [obviously more oil in the axle would be required too].

Some oil will be retained in the space for the bearings, all the oil will not flow back unles you turn the vehicle on its side and even then there might be some oil that will not flow back into the diff housing.

You have to use double lip oil seals as per the part number above and remove the little seal that is inside the axle tube that seals on the axle.

nope, not unless you were planning on doing 40% side slopes for 10's of kilometers at a time.

doing the conversion is as simple as greasing the bearings (for the initial lube) omiting the oil seal from the inner of the swiv for the front axle and pulling the shaft seals on the rear then upping the oil level by about 600ml for the rear and topping up the swivels oil level.

Some people also pull the front diff tube to swivel housing oil seal and allow the diff oil to flood over into the swivel housings. The risk there is once one is contaminated they are all contaminated the benefit is that the swivels always pick up extra oil on cornering/side sloping.

IMHO your better off leaving the front diff-swivel housing seals.

but you also have to remember that the seals in the swivel hub for the axles should be looked at too as these will reduce the oil coming into the cv/bearing area... but is the axle oil correct for longivity of the cv?? I think not therefore we need to take into account the required lubricant for the cv and the wheel bearings.... not as easy as remove a few seals and hope for the best as all areas require a different amount/type of lubricant
