Greasing Bearings and Hub for Dexter EZ Lube Hub and Drum for 5.2K to 7K Axles, 8 on 6-1/2

Question:

I am in the process replaced my Hubs on my Grand Junction 5th wheel. I have ez lub axles. My question is i have hand packed the bearings and also put about a handfull of grease in the hub cavity ..after installing do i now use a grease gun and fill the remainder of the hub cavity till the grease start s coming out around the castle nut?? or is the hand packing sufficent. my concern is blowing the grease seal. Can You give me advise?

If you have EZ lube axles then the hubs most likely use a double lip seal (which is what comes with hub # 42866UC3-EZ) that is going to be able to handle the use of a grease gun. But make sure to use a manual grease gun because the powered models do create much more pressure and can blow a grease seal.

Make sure the grease used in the grease gun is the same as the grease used to pack the bearings or, if different, make sure they two greases are compatible. I have included a link to a helpful article on grease compatibility.
