Question:

Wondering the greasing process on the #84 spindle, if you fill the hub completely up. Seen videos of ppl shooting grease thru zerk fitting until the old grease comes out. So the hub is packed completely full? Or do you have any recommended videos on the greasing process of spindle/bearings/hub. Thanks

I have linked a video below which covers replacing bearings as well as greasing your hubs. If your Spindle # TRU74FR already has a grease zerk you want to fill the bearings with Grease # L11390 before assembling the hub. Then use a Grease Gun # L30-310 to completely fill the hub.

If your spindle is not an easy lube style with the grease zerk you can use a Bearing Buddy style cap like the # BB1980A-SS which will allow you to fill your hub. This particular unit has a check valve which pushes out when the hub is full of grease.
