My Hubs were no good either. I went to american bearing company for those or you can use timken.

Unfortunatly I wanted Timken but I was pressed for time and couldnt wait for them to come in. You can buy Timkens @ carpartswhole.com for $250 autozone wants $350. So if you are going to replace you bearings you cam save 200 if you order ahead of time. I bought them for my Expedition and they were good to deal with. I used Federals. They have a two year warranty. I recommend Timkens though.

i ended up finding a timken on ebay for $145 when i did mine. and it was shipped fast.

Timken HA590020 Front Hub Assembly | eBay

any way to figure out if the hub assembly is bad before you rip it all apart?

Jack it up with the wheel on and try to shake it for play then turn the wheel an check for play again because it could have a tight spot and you wouldn't kno it's worn out.

My pass side bearing was shot. The only sign was humming while driving. When I jacked the truck up I wiggled the wheel and spun it. It felt tight and right. Spun with no sign of a problem. It wasn't until I pulled the assembly off and checked the bearing. At that time there was no doubt it was bad. I recommend buying the bearings and having them on hand like I didnt do. Especially if you are pressed for time. You can always return them. But my bet is you will use them. Invest in antiseize and coat everything with it. I would order them off the net to save yourself a few bucks unless you get shop rate at your parts store. One more thing is greaseable ujoints. Napa has them. Everybody else says they ate not available. Carpartswholesale has them too. Get greaseable everything! Grease every oil change! Just my 2 cents!

yea im going to napa for ball joints and universals, but idk if i can afford all new hub assemblys haha they are pricey
