Don't ignore your bearings!

my 2 cents: Zerk fittings are a bad for modern bearing assemblies.  Squeezing too much grease into them can force grease around the seal and once the grease around the seal is dissolved, allow a path for water intrusion.  Zerk fittings are from a time when seals didn't even exist and you had to squeeze in grease on a daily basis to keep out water.  They are still used on joints that don't have bearings and/or don't have seals, like on tractors.  Those zerk fittings are probably on there for when that axle is used in boats, boats are a little different because you splash hot bearings into water and make steam, which easily dissolves grease.  I don't think there is a single zerk fitting on modern cars.

Originally posted by Anthony Valenzano I re-greased my bearings on my 2010 yesterday.  They were in very good shape.  No signs of rust at all.  I was surprised at how loose the castle nut was.  I wouldn't even say it was finger tight.  So I'm glad I looked at it.  There might have been enough slack to start some wobble.  Normally when I do bearings, I tighten them good with a wrench, at which point the wheel won't turn, then I back them off until the wheel spins freely, then back it off until I can insert the pin.

That is a good rule of thumb on the castle nut.
