FedEx Freight just recently changed their entire fleet back over to grease packed bearings.

I agree with the former, not the latter.

Trailers, unlike trucks, tend to sit more and do have issues with seals drying out and bearings rusting. Most all trailers are oil bath but like you said...

My end analysis is that oil bath is a slightly more advantageous system, but proper monitoring and maintenance render either as adequate or not.

What grade of oil would I need 94=104 or higher?

If you don't know what's in there, and you're not changing your wheel seals, probably 85-140 would be ok. Rusty, who in a former life was a lube specialist, might have a better answer for you.

If you are changing the wheel seals, maybe a newer synthetic might be better.

You could just fill it with the Lucas Hub Oil if you wanted, they claim it is better than regular oil.

Use the manufacturer's recommended viscosity (i.e. 90-140), and grade (EP, HD, etc.).

IMHO, Kendall and Mobil have the best automotive gear oils.

Thanks my oil is up to the line buy I will put one in my mh. box just to spend more money.

Personal preference is synthetic grease, but would not change one out to get the other.

It is my understanding that water will displace normal grease and a good synthetic will displace water.

However in the HOT desert the oil will dry out.

You mean, like evaporate? Or does it cook off and out-gas?

Some synthetic greases use a proprietary thickener which doesn't have some of the drawbacks of lithium soap based thickeners, so they stay in place better in the presence of water. WGL and Super Lube Multi-Purpose grease are examples.


The oil doesn't "dry out". What happens is "separation" (of the base stock from the thickener), and the oil migrates away from the area, and the thickener remains.

Many "Synthetic" greases also use a lithium soap based thickener, so separation is still almost as much an issue as with mineral stocks. The synthetic base stock is somewhat more long-lived than the mineral.

thanks guys got the oil now I am getting ready to use it monday for two weeks.check out journeys.
