CR Rear suspension mods

[Aussie Mike]

Another update with a few more pictures.

I tackled one of the more difficult jobs on the rear end modifications. The Axle flanges to adapt the Commodore axles to the Ford Hubs. The Commodore axles are narrower than the Ford and use a bolt up flange. I like these axles because you can just about remove the whole axle without unbolting all the rear suspension. I had made flanges previously when I did the Commodore diff conversion. The new ones had to be 50mm shorter for the narrowed rear end.

Here's the completed axle flange. It's made from an AU falcon axle mated to a Commodore diff flange. There was a lot of machining and setting up to get this together. The material the axle is made from is very hard and my tungsten carbide lathe tooling wouldn't touch it. I ended up having to rig up a tool post grinder to machine it down.



The 2 pieces are TIG welded together inside and out so should be strong enough. There are only drive loads going through the flange as all the suspension and braking loads are taken through the suspension arms.

The other thing I like about this setup now is that both CVs (inner and outer)are pretty close to in line with the suspension pivot points.



The next job is the new shock mounts and sway bar attachments.
