Rear Wheel Bearing??

Balla!

Wow the bearing just showed and its a big part for such a little car!

You have a dollar? I'm impressed.

It is not my dollar.......

It is not my dollar.......

I was wondering where I left that. Give it to me next time you see me!

Wow that job would be a lot easier with a press. Biggest PITA is getting the old bearing race off the hub.

But with my trusty hammer I was able to change out the bearings and as Rogue had said it was the rear wheel bearing!

[onething]

Is it fixed yet? Did you use the hammer to install the previously good bearing?

Heck I even drove it to work this morning it is so nice an quiet.

I have to chime in on this one.
If you use a hammer etc to forcibaly remove or install the bearings you really stand a chance of cracking the outer race, or damaging the housing. I haven t had to change any on a Miata yet, but lots on the race car and from the picture it looks very similar.
Easy method for the housing, use at your own risk:
To remove the bearing, its dead anyway, use a propane torch and gently heat the housing around the bearing. Its a different metal so it expands at a different rate. usually needs the housing to around 250 degrees or so. Bearing will still need persuading but will stand less chance of scoring or otherwise damaging the housing. Damage here means the bearing can spin at some point or worse crack. If you are good, try a little freeze spray on the bearing. Hard to do.
To reinstall: if done right the bearing will fall in without any extra pressure. Take the bearing and put in the freezer for 30 minutes to an hour. Heat the housing again to warm enough that you almost cant touch. Take the bearing out of the freezer (move quickly here) and shove in the housing and the bearing should fall in.
Dimensional info: Most press fit bearings are sized around .0005 to .0015 bigger than the hole they go in.
Like I said I havent measured the miata but it looks similar to the one I use. When we are racing the Swift, it will go through at least one or two sets a year. Depends on how often the car is on the banking at TWS or TMS.
If nothing else chilling the bearing will make it much easier to drive in. Beware that once the temps start equalizing, it gets harder so getting it right makes it drop right in.
