So this evening I was doing some PM work on my Summit and noticed that the Dust Covers [(5378x)I think] were tore up quite a bit. Check your that part number on your trucks and tell me if yours are the same please. It's not clear in the exploded view book so it looks like 5378x or 5334R, not sure what the difference is.
Let me know what shape yours are in as all of mine have a bunch of tears in them.
Also, while messing around I heard some "crunching" coming from the axle bearings, I checked a couple of them and some had grease and some didn't. I'm thinking I need to tear them all down, clean and re-pack them, what grease should I use to re-pack them with?
