Hybrid 970

Superzuki1986 · May 4, 2016

Spider 9 bare housing.
Dana 70 spindles.
Dana 70 hubs.
Dana 70 35 spline axles.

Got a deal on the 70 and a SRW 14 Bolt.

Disassembly of the 70

Cutting the housing.

Axle tube cut and ready to bore to a press fit over the Spider 9 housing.

Boring complete

Spider 9 housing cut to the proper length and Dana 70 axle tube bored for a press fit and cut for plug welds. Ready for welding

Welded

Some assembly required.

The last pic is a sneak peak of what is to come.

I did something very similar using a stock 9" housing and 14 bolt spindles and 35 spline shafts. It was paired with a 9" front using superduty 8-170mm outers that I redrilled. In hindsight I wish I would have used unit bearing cups and 05 up bearings on the rear axle with double splined shafts. That would have allowed me to use metric wheels without redrilling anything. Live and learn I guess. It is holding up well, only broken shafts.

Well done.

Could you please weight it fully dressed with brakes?

I liked the SRW 14 Bolt spindles and hubs better but chose the Dana 70 for the replacement axle shaft availability. No custom shafts were one of my goals. I want to be able to get stock parts in an emergency if it brakes.

I am looking for a set of scales as we speak. I really want some race car scales rated for 750 per scale x 4 scales. Like the round track guys use. I'll post weight as soon as possible.

Forgive my ignorance, but are you still utilizing a 9" ring and pinion? I guess weight is the main goal here? Light weight, full floater with 35 spline shafts? Does sound nice! Great work.

Love the guards on the saw. >

Yes, still using a stock Ford 9 inch carrier with big bearings. My goal was getting a good "strength to weight ratio". Not necessarily making a light diff.

On the fan. I got the saw used and without it. I know it probably should have one but with all the other dangerous stuff in the shop it seems trivial.

Any updates on this?

Why not just make or buy new spindles and weld them to the tubes in the 9. :dunno:

The way you did it will work. It just looks jacked up. :****:

Stronger and cheaper this way considering the Spider 9 housing is only 3 inch .250 wall tubing and this rear diff has .500 wall. I chose not to machine the spindles free from the old tubing for these reasons. I'll take strength over bling any day.

Not really. You just moved the weak point in. If you wanted 1/2 wall why not make the entire tube 1/2 wall.
You can cut up an axle. So why not?

Re:

It is stronger because the link bars will be mounted as far outboard as possible, moving the 'lever' further away from the small tubing. This is in a sub 3000 pound buggy with a stock 22RE. Even at a single 3" .250 wall housing it was overkill.

this layout is easy to truss as well. adding the strength back should not be an issue if its needed.
