Re: swapping tapered axles for later flanged axles



…..if you use the Green bearings, you can leave out the thrust blocks….. they are needed with the stock roller bearings  with the sure grip carrier.  The thrust block acts as a stop for axle side play which the adjuster sets so there is not too much play or too much preload.

The green bearings have a snap ring in a groove which allow the retaining plate to locate the bearing in the housing end without side to side movement.

leaving the thrust button in place when using green bearings MAY cause side loading on the green roller bearing, which can lead to premature failure. This may be the cause of reported green bearing failures in the past.

For those that do not trust the green bearings on the street, keep in mind the various axles were equipped with roller axle bearings from the factory.

Nick, The following is a section from a Mopar 8 ¾ rear end guide that explains why you had to shorten the axles on your 63 Fury.

 

Section 1: Thrust Block Variations

There was a difference in thrust blocks prior to 1964 that make center section interchange, as well as axle interchange problematic. The thrust block, or "axle shaft thrust spacer", it’s the block that both left and right axles butt up against inside the center of the differential. Prior to 1964, all open differentials used a thrust block was approximately 1/8" to 1/4" thicker than units made after 1964. The Sure Grip thrust block prior to 1964, however, was indentical to all 1964 and later Sure Grips and open differentials. In 1964, the thrust block width was changed to match the Sure Grip thrust block width.

This difference in thrust blocks between Sure Grip differentials and open differentials required that two different axles be produced for each 8-3/4" housing manufactured. This is true of all 1959-1963 cars with 8-3/4"s.

A 1964 and later differential, or any Sure Grip differential, cannot be used with 1959-1963 rear ends and axles originally equipped with an open differential. The original axles must be machined or original Sure Grip length axles must be used.

On my '63 Fury when changing my 741/2.76 Non-Sure Grip for a 742/3.55 Sure Grip unit I found that I had to shorten my axles 1/16" to fit the SG unit. I figured this would be the time to swap to the flanged axles. I was not able to find any information about this swap. I changed over the swedged hubs, shortened the axles and has been good for ten years far. Our '63 housings drum to drum are 58 1/2" which allows us big tires. The '66 units are 59 1/2" and are a good replacement as Herb said. If you have the funds, or as racers often do, build a unit with custom length axles.

 

I run 285/70R15 tires on 15x7 wheels with 4 5/8" BS. I ran the same big wheel tire size on my '63 SF.
