I prefer greasable/serviceable parts.
I very particularly hate the unit bearings that new trucks have. $350 to do the front wheel bearings on one side of my 2006 GMC?

It cost me less to buy all new bearings and seals for my 1986 1 ton, and pinion seals as well.
Some people hate serviceable stuff like that because they say water gets in them and you have to repack your bearings more often. First of all, at least I will have the option to repack them. Second, those unit bearings have seals too.....seals on them can leak and let moisture in, they aren't immune but you can't do anything about it except replace it
Yeah, I definately prefer the greasable stuff!
