How to grease axle on older popup?

[Reach100]

I have a 1989 Jayco Popup Camper. When I take off the axle covers, there is no nozzle to attach my grease gun to. I bought #1 M6 straight replacement nozzles but they don't screw onto the hole. How do I get the grease in there?

The hubs need to be removed and then the bearings are greased by hand. One of many videos on YouTube.

I did not watch this video. But you just need to pull the whole hub apart and repack by hand. This is how I do all my trailers, including ones with Ez-Lubes. If you do not pull them apart you never know if the bearings, races and other parts are in good shape.

X3, if you don't have zerks your axles likely aren't drilled for greasing. Hand pack is the best way anyhow.

Hand-packing is how it's been done for over a century. though there are some very nifty tools to assist these days. Greaseable dust covers aren't a substitute for repacking the bearings but it does let you go longer between jobs by reducing the likelihood of running without from seal failure.

Also make sure you have seals on hand. Even if the bearings only need to be repacked, you’ll likely tear up the seals and need to replace them.

Good suggestion. seals are probably one of the biggest contributors to later failures whether it's tearing them up, folding the lip, catching dirt underneath causing premature wear, or some other failure mode, for the price just do it.
