replaced my left wheel bearing - pics and details
I was changing my front rotors in prep for an upcoming track event and noticed the left front wheel hub toggled a bit and made a rough sound when i turned it by hand, the right side was tight and made no sound when turned so i decided to replace it....here are pics and details if you ever need to do it.
Parts you need:
-new bearing assembly - part number GA5S-26-15XA
(this part includes the hub, bearing, wheel studs, and abs ring all in one... also i think it is the same for either side in the front, but I'm not positive)
-new hub locking nut - part number LA01-33-042B
Tools you may need:
- impact wrench to remove old hub nut (my feeble 250ft\lbs air impact wrench took it off with no problem)
- massively huge torque wrench for the 131-173 ft/lbs tightening requirement (see pic of manual below)....I set it to 150 ft/lbs, figured it was a good in-between number
- massively huge socket for wheel nut (I got a 36mm and it fit well, but had a little jiggle room so a smaller one may fit, but my local homedepot jumped from 30mm to 36mm)
Here are the old and new next to each other, the old one was obviously toasted.
Close up of old (and toasted) bearing.
Close up of new (and ohh so pretty) bearing.
Shot of new hub/bearing assembly on the car. It looked so good I was tempted to change em all just for the 'new' look, then i remembered that you cant see them with the wheels on (heheheh).
Pic from manual showing the tq setting for the nut and that you need to 'stake' the nut.
No toggle now, tight as can be

That is an awsome price for the whole front hub.!!!! Saves hundreds! FWIW: You can replace just the wheel bearings. The process is a bit time consuming but is worth it to save the cost.( It can be found on the Mazdatrix website under the FAQ section)
The biggest thing that stops one from replacing the bearings is that there is no "lip" for you to get the removal tool(punch) onto. The process on the site tells you how to grind a notch in the bearing race so that you can get the punch on the bearing in a few different places and remove the race.
That was until this price came along.. Plus yours are nice and shiny!!.Are there restrictions to purchasing from them?

Yeah I would to espeacially for that price!! That's what i was expecting to hear from ol'Ray @ Malloy. But my price which is usually awsome was somewhere around 350 bucks!!. Hence why I looked for an alternative.
As for the Auto-x or track proof .....It's hard to get to a track for me out here. I have to ship to Oahu from my island And then back here. About 1 month all round. Hopefully this year I will get more serious and just ship it and deal with the expense...Got to pay to play right?

Roughy, how many street and track miles where on the bearings before you toasted them? I've always wondered how long they last under track use.
Edit: Did you notice any differance in pad knocks back?
