As mentioned in a previous thread, both front bearings have excessive play in them which the dealer denied for warranty repair due too "larger tires and lift". So i was forced to replace myself. I thought I would document the work along the way as I haven't found a complete DIY thread with pix.
43570-60010 - bearing
90312-96001 - Hub seal
90316-A0001 - Spindle seal
90301-92003 - O-ring
New bearings and hub seals.
Whats not shown is the o-ring that goes behind the bearing assy. and the oil seal that is pressed in the spindle itself.
Start by removing the "grease cap". Why is it called this? There is no grease inside! I read some threads where people were having trouble removing this. I got each one off in under 5mins. The trick is placing a screwdriver like this and hammering away, all the way around the cap. Then pry off once its loose.
Then using a 35mm socket and someway to immobilize the hub, pop the drive axle nut loose.
I then removed the caliper and speed sensor. This was my first clue something was amiss. When i removed the sensor the tip of it was covered in a sticky muddy goo.
Next, pull the rotor off and remove the four bolts holding the bearing assembly to the spindle. You wont be able to fully remove them but loosen as for as they go (they end up butting up to the hub). I gave the axle stub a whack (rubber mallet) to make sure it was free to slide in the hub. Then beat the pi$$ out of the bearing along the 4 bolted flange. I had to use a chisel along the edge to get it to start to break free. This was the most laborious step so far. Once off this is what i found.
No wonder the bearing failed! There were pieces of the spindle seal laying in the bottom. The o-ring was broke too, but not 100% sure that didn't happen when removing the bearing assy.
To be continued.... o-rings on order.

I won't have the o-rings for a few days yet, so I want to get as far as possible without them. The main culprit that failed allowing water, mud etc. into the bearings was the seals in the spindle. In order to replace these you must remove the spindle. Very easy. I started at the bottom ball joint, removing the two 19mm bolts. I placed the floor jack under the lower control arm to support the spring tension. Next remove the castle nut on the upper ball joint but do not take all the way off. Hit the spindle on this flat spot shown in the pic really hard a few times and the ball joint pops right now.. its not under much tension but the nut keeps things from flopping around.
Here is the spindle seal.. it gets driven out from the front with a punch. Installation is just the reverse. Tap sound the circumference until its fully seated.
Now at this point the spindle is ready to go back on and all that is left to do is the bearing assy. After looking at the old one, there is not an easy way to press the bearing of the hub at home w/o some fixturing and a press. However it does appear once the hub is free, pressing the new bearing on can be done in any number of creative ways, big vise, bottle jack, etc. I have a press at work I may use. So to get the old bearing off i used an angle grinder and die grinder and cut cut cut. I probably went a little overboard as what I found is the metal races are tempered hardened steel. Example in the inner race still attached to the hub... Grind a slit in the bearing race and use a chisel. Couple good hits and it cracks all the way through releasing its death grip on the hub. Here is whats left afterwords.

No not too many water crossings normally. I am pretty convinced this is what did them in... What looks like water and mud is actually very fine silt, left from a mining operation. This crap got into everything.. wasted my idlers the next day!
