OK.... I figured out that the axles are the same, although slightly different looking. I popped them back out again today and noticed something else that was a little disturbing. The axle doesn't seem to seat very well to the hub. I replaced the O-ring and hub gasket, but there is a small gap between the hub and the axle which produces a small leak. On the drivers side, I can actually move the hub in and out when I have the drum and axle removed. It doesn't move much, but there is noticeable play in the hub. Obvioulsy this is not good, but is it just a bad wheel bearing or is there more to it than this?

Thanks.

Did you tap the axle home into the inner seal with a big rubber hammer?
Did you put the little screw back in?
It will move a little until the wheel is boltd on since that one screw doesn't hold it tight all around. But with the screw in, it shouldn't move in and out.
It might wiggle ever so slightly until the wheel is on.

yes, my axle/hub gap looked the same when I first put in that screw, so I did almost the same as hpmowog. I took out that screw because I thought it might be oddly stressed, put on the drum and tightened the two drum locating screws, and that closed up the gap nicely.

With competition axles on my '63 Sprite, I always used four lug nuts, and perhaps a washer or two on each stud, to pull together the axle flange and hub face. See the suggestion above by Karl.

A gap of 0.08 mm ?? This is about 0.003 inches. Use a thicker gasket ??

Thanks for the replies. The axle twisted at the splines, but did not actually break.....it didn't have much longer to go though! I did pull out the diff to replace the pinion seal as it was leaking oil. It looked to be in good shape....no worse for the wear.

I supose it gets snugged down once the lugnuts are tightened up, but man.....it just doesn't look right when the drum is off. I would feel better knowing it had a bit tighter of a seal.

I think I'll live with it until I get an upgraded rear axle assembly installed......with the extra power I'm putting down, I will be replacing axles every month! I've already trashed one diff and now an axle.....anyone here do the RX-7 rear end swap?? I have a link to a website that details it very well, but it might be beyond my skill level.

Anyway, thanks again.

Rear end whine

Postby Bill Masquelier » Mon Mar 12, 2007 2:07 pm

Mike
You say that you just replaced the pinion seal-- I bet that your new whine is from an incorrect crush-piece distance from when you retorqued the pinion nut. that distance is critical.

I didn't see this mentioned, but check the hub face for flatness. I have found damage from hammering on the O.D., and evidence of using a chisel to separate the axle which upsets some metal. Sometimes just using a flat file on the high spots is enough, without having to remove the studs and bearings.
