TX iceman, yep that is what I have, the Dexter axles. Going to need another tube or two of grease..
If you put even a half tube of grease into the four hubs, you will likely grease the brakes.
I have that system and have pumped many tubes of grease into them and NEVER had a bit of grease come out the back. I have disk brakes so it's easy to tell.
Use quality synthetic that will flow easily. DON'T use a pneumatic grease gun.
Have someone spin the tire and pump as fast as you like and the old grease will start coming out. Simply wipe off and when new grease appears you are done.
For this system to work properly you need QUALITY seals like National.
All sounds good ,until it doesn't . IMO nothing replaces hand packing those bearings. Where do you suppose all those tubes of grease go if that old grease does not come out, you failed to mention that ,then what. Stop pumping , maybe, maybe take a look behind the hub ??? Two things pack the bearings by hand ,and inspect ,and adjust brakes if necessary . No not all have disc brakes .
I bought my present fifth wheel from a friend , and the bearings were not due to be packed ,according to him. Well I got lucky ,I had a slow leak in a tire that needed to be fixed ,removed the tire ,not knowing the size of grease seals, thought it would be a good time to see for future bearing packing. I pulled the caliper, I do have disc brakes ,and the brake shoes were all but wore out, so close I would of most likely ruined some rotors on my summer trip. . If I did as purposed by many , pumping grease into those bearings I would have ruined some rotors. Plus the wheel bearings got packed properly, and new brake shoes ,good to go . Ya ,no fan of this pumping grease into those bearings, and would never recommend it .
