[Fot] Southwick Conversion axle float

Sat Feb 18 19:25:31 MST 2023

On my Southwick conversion I had to weld up the 4 holes in the brake plates re-drill them.  I use my TR3 on the street too, so I run the stock parking brake.  The parking brake brackets needed to be in proper alignment and were not after Southwick drilled them.

I did notice that Southwick had drilled the backing plates such that they were no longer indexed the same radially as stock. I don't know that it's a major issue, but it was odd. I was able to re-drill two holes on each one and get them close to the original position...

Southwick uses the “Small” Ford bolt pattern, and the Small retainer that fits it overlaps with the bearing a lot. I ordered some Small retainers from the Bronco Graveyard in SE Michigan. Easier than making my own.

It fits over the 2” OD  bearing retainer shrunk on the shaft, although i opened it up about .040 to give some clearance. The OD of the thrust washer needs to be turned down a bit to fit inside the axle housing. It is just about the same thickness or .002” thicker than the backing plate, so the bearing will be captive and have no end play.  As some of you advised, this will go inside the bearing housing rather than inside the backing plate.

When putting in the axle shafts I noticed an indentation on the axle bearing retainer from the bearing slamming sideways into it. Southwick machined the bearing housing ends the full width of the bearing. Because the backing plate fits over the bearing, there is nothing to keep the bearing all the way in the bearing housing, and it shifts side to side in the void left between the retainer and the backing plate.
