It's hard to get too much grease in there. I recently replaced all the wheel bearings and races on my D60 and I gooped a lot of grease on the spindles, bearings, and inside of the hubs. But you didn't ask the conversation starter of "What kind of grease?" I'm sure everyone has their personal favorite. I went with Paragon 3000 but the previous 70k had cheap Mastercraft grease from O'Reilly.
I went down the wormhole of trying to find the best grease actually, and lost a few days time trying to decide actually.
I made the mistake of searching best wheel bearing grease, and i quickly discovered there are Many options and opinions, before that search I just thought grease was grease, but I was quickly educated!!! lol
Grease brands are like beer or sports team, everyone got their personal preference.
Some people like one grease because that’s what they grew up using, and others just stick with one they had good luck with.
I went with the Lucas red and tacky, because
A) Quality brand name
B) Says right in the tube it’s NLGI rated for wheel bearings
C) let’s be honest, the truck don’t give a shyt lol
