The '94 has a RRRrrrRRRrrrRRR noise as it rolls down the street local hero Rogue said it sounded like it could be rear bearings.
Checked end-play and the rear bearing appear to be in spec but the noise persists. So it is time for me to listen to Rogue and fix the darn thing.
Anyone tacked this job lately any pointers for us first timers. ;)
IIRC, I replaced the whole hub/axle assembly with a rebuilt unit from that place in Hurst on the northwest corner of Precinct Line and Hwy 10. Have fun getting your nut off.

I don't remember it being too hard to get it off the car, but I had to have somebody press out the old and press in the new.
No, but I can probably find it at home tonight.Quote:

You do not necessarily have to have 'wheel play' in the rear bearings to realize the bearings are going bad. As for price, I think the price was less than a $100 for both sides. I would replace both at the same time if you Auto-X or track your car. Good luck with your nuts. ;)
I just ordered up one side from Rockauto (Bearing, Seal, & New Axle Nut = $41.79 shipped) figure I'll try one side first and see how bad the job is.
I got a breaker bar and a pipe so I'm not real worried about my nuts. ;-)
I have gotten a few nuts off in the Miata. It can be pretty satisfying when it you finally get it off.

Let's hope your wife doesn't find out about this...Quote:

I just looked at the bill. It was $72.15 to replace and repack the bearings in one hub.Quote:

I know the guy can rebuilt the CV Half Shaft Assemblies if needed.

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

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