[DeTomaso] Rollers or Balls?

[David D Fisher]

I'm replacing my rear axle bearings while I renew all the suspension bushings 
and have noticed some previous discussions on roller bearing conversions for the 
rear axles.

I'm interested in folks opinions on the merits of changing out the balls for 
roller bearings. Ideally,  I'd like data on long term roller bearing longevity, 
but failing that, I'm interested in opinions, and experiences.

On my car,  I noticed the outside bearings are rough and the inside ones 
(larger) are still smooth.   Curiously,  one side of my car has a shorter spacer 
between bearings than the other side, although both carriers seem to be 
identical.   I suspect someone changed a bad bearing and put the wrong spacer 
in??

Lastly,  I'm running 335/17s on the rear, which I suspect are less than ideal 
for handling, but who can resist the bada** 70's look they impart?   I just 
changed rear rubber and noticed that the inside of the tires have worn down a 
fair bit faster than the outsides.  I am contemplating compensating with camber, 
but I suspect there may be enough flex in the rims, suspension and frame that I 
might just have to live with the tires wearing uneven.  Any thoughts?

Thanks
