My turn for some differential work - Page 2

Bob, Bish & ZDerf;

Thanks for advise. I will have the axles checked out by a machine shop. One thing in my favor is that I have a shortened 9", and therefore, the axles had to be custom made. So whoever went to the expense of having these axles made likely had them hardened? How can I tell?

The only thing hardened in my earlier diff's life were the criminals that customized the axles!!! My custom "narrowed" shafts were turned from the original shafts... and were not "properly" hardened. At least that's the prognosis of NWD. That is why mine twisted so far before it snapped.

You cannot determine hardness by eye. A machine shop that has a hardness tester should be able to check it for you (preferably a sonic type so you can measure the spline area without marking).

Bish is right about the damage done at failure. That's how my bill got so frapp'in big.... oh, not to mention sitting road-side for a couple hours whilst cars went by gladly honking at me (har-har-har) as they went by.

Ummmm. I'm thinking new 31 tooth'ers. But, your money is easier for me to spend than mine!! (I had NO CHOICE)

Happy decision time!!!

Mine too were shortened stock shafts. They were twisting and were about to break. From what I have seen, the 28 tooth splines are machined "down" into the axle, the 32 tooth splines are on an oversized axle so you don't give up any meat, plus the hardening. Also means an over sized bushing at installation.

Somehow I missed your last couple posts from early February?

Anyhow, I'm here and I've been working hard at it. I pulled the axles and took them to Jim Green's, they magnufluxed them, checked them for hardness, and inspected the splines under close scrutiny. The result was that these axles are in perfect condition? I thought that I had abused these axles in the past with some neck snapping "hole shot" passes at SIR with drag radials. If they made it through that without a scar then I figure I'll stick with them and put the money I would have spent, into other things.

I also installed a Detroit True-trac, went back to 3.00 gears (the 3.50 were too short for freeway cruising with a 3-speed auto). All new bearings and seals throughout.

Then the money I would have spent on the axles went to Eibach 250lb./in rear springs, Koni adjustable shocks, Energy Suspension bushing at all 4 rear control arms, new rear brake calipers, turned the rotors, and 3" NHRA spec wheel studs.

With a full day tomorrow and a 1/2 day during the work week I should have it all back togther for the 16th. My fingers are crossed.

You been a busy boy. Glad the axles checked out and you could spread the $$ around a bit. See you next Sat.

Bish

P.S. How's the baby?

Awesome update!! You've been styling right along, the whole time. What was I thinking?

This is great news....

Wonder what Brent, Fred H, SteveT, and all those other guys we used to hear from have been up to?

I'll post something regarding next weekends meeting round about Wednesday....

See you next Saturday at the Hook!

OH... BTW, Rich and I are headed for the Roadster Show Sunday, as the doors open at 10. Maybe see some yawl there??

Regards,

Zderf

Think I'll venture out of the far north and go to the Roadster Show too. I'll try to find you guys.

And I was wondering who owned the three cobras there...no one around to claim ownership, that we could see?
1) A silver ERA from Oregon
2) A black FFR from WA
3) A Red Classic w/white stripes

The star of the show in my opinion was the 1940 Ford Phaeton, by Steve's auto restorations of Portland, Oregon. It was an unbelieveable work of art with extensive shaved brass trim which was chromed, and Chuck Barr, the general manager, took me inside the rope to peek under the hood and inside the car's interior, that is until one of the show monitors came over and told him he could not take folks inside the ropes to show his OWN car! These people (the people who run the exposition center) are your average Seattle liberals, they even wanted to search my wife's purse when we entered, after paying $13.00 each to get in to a (totally peaceful) exposition, and $8.00 for parking in a nearly empty garage!!! I think the guys doing the entrance "search" felt pretty bad about it, actually.

Seattle. I usually love it, but sometimes....

Thanks for asking, Baby Lauren is doing great. I took this picture this evening, she is now 5 months and 10 days.

I'll try again?

Well not sure what's going on, I reduced the file size below 20K bytes, but it still won't post?
