My Kia failed its annual safety inspection so I'm going to be replacing the front wheel bearings (both front wheels have top-to-bottom play when up on the lift).
Some people say you should only use enough grease to thoroughly fill the bearings themselves. Others say things like "you can never have enough grease" and suggest packing the entire hub full of grease.
I have also read that too much grease can cause overheating and leakage issues. Others say that filling the entire cavity with grease means that there's "no room" for anything else in there...such as water (I've heard this is mostly important for boat trailers where the wheels get submerged though).
How much grease is the right amount when packing wheel bearings?
(For reference my car is a 2002 Kia Sportage rear-wheel-drive and it uses the tapered-roller style of bearings)
