<VV> Rear axle bearings, late

[jvhroberts at aol.com]

 Yes, it was for front wheel bearings, but the point is the same, pack the cones, smear the races, and not much grease anywhere else. 

Given that Corvair rear wheel bearings use the same inner front bearing on the outside in the rear, and a pinion bearing as the inner bearing, the lube requirements are similar. My guess is, the rears require the same as the fronts, but are such a pain to deal with, it's not worth it to PM them. So, replace when they die! But by packing them with a top grade synthetic, as per this method, they should last nearly forever.

I followed the link to the Corvette web site, but it is for the front bearings 
and not the rear. I was interested in what they had to say about rear bearings. 
I didn't see any info on rear bearings. 



As I remember, both the Corvette & Corvair rear bearing assemblies are very 
similar with the only difference being the clearance, Corvette wants 0.001 - 
0.008 and the Corvair 0.000 - 0.006 clearance. Disassembly of the Corvette rear 
wheel bearings requires a press and I can't remember if the Corvair is the same, 
but I would think it does. 



The big difference between front & rear wheel bearings is the method of 
adjusting bearing clearance. On front bearings you do it with the spindle nut, 
while on the rear bearings you do it with shims. Once you get the feel for it, 
rear bearings are not a problem, as long as you have access to a press in case 
you need it and you most likely will.
