Hot Rods ??? Front wishbone to locate rear axle ???

Hi fellas. I've been searching for a thread that's a couple of years old. Someone was building, I think, an "A" pick up and used a front wishbone complete with perch pins to locate their rear end. Can't find it.

I'm re-doing some stuff on my modified and this is one change I want to make, just to make the rear end location a bit tougher. I know I can sort it out by myself but I recall that this particular truck was well done so I would like to have another look at it before I set out on this.

If anyone knows what I'm talking about or has done something similar, I'd appreciate the help.

Thanks, Pete

 

Sounds like NEALINCA

 

I was just looking at some pics of Neals build. I don't think that was it.

 

Hmmn. well that is the only build I know of with a front bone used in the rear. I'm sure someone else has done it and I'd like to see it too now.

 

That rear engined flathead 32 pickup with no bed, built back in the day, is ringing a bell.......may be way off. It was in TRJ a few issues back. Or was it a twin engine?

 

I already have my '48 rear radius rods made into a wishbone and located using a ball the way NealinCA did it. I'm going to keep that front mount but want to use a spare '48 front wishbone I have to replace the original rear radius rods. The part I really want to see is how the mounts are made on the rear axle to mate to the wishbone.

I'm considering cutting up an axle to weld to the rear housing and using the original perch pins.

 

The Kenz Leslie truck.

No cigar this time I'm afraid. It was a build thread on here maybe 2-3 years ago.

 

Pete,

I remember the pick up - it was a 30-31 closed cab pickup, built by a young guy mid USA.

I had the pics on my external disk drive, but cannot find them at present

 

This is Neal's build:

 

Yep, that's how I remember it.

 

...

 

i hope someone figures this out. I wanna see it!

Yes. That's the idea. Still not the thread I was hoping to find though.

Thanks for you help too harv

Pete

 

Well I just searched 20 pages of related threads. Found some good stuff. Found other people referring to the thread I want but still no dice.

Not to worry. I'll just make it up as I go along.

 

I thought I'd bring this back up one more time at a better time for the US crowd.

Thanks, Pete

 

How bout this one?

It's mentioned in there and I asked if the ball/socket is strong enough for the push load on it, no answer yet.

 

One idea I have toyed with is to mount a front wishbone to a rear axle using fabricated brackets with a correctly sized tube for the pin. If you used 28-34 style spring perches you cold also mount a cross spring forward of the axle. Thinking modified here. Just an idea.

 

I was just reading a magazine with a nice step ny step tech on this. I'll get the issue and title for you, but you're gonna have to wait until I'm done with my tequila

 

I did cut down front wishbone on my 30-31 A pickup

90 days and a 2 week follow-up?
Don't do it!

 

Nope thats not the thread Pete is referring to - but there is a great discussion on rear radius rods though. Thanks for bringing it back up

 

If you can wait til tomorrow, I'll take some nice pix of how I did mine, using a Model A front yoke mated to '36 rear bones, and tied into a 10-bolt GM axle. I used 1-inch diameter DOM tubing to fabricate torque arms/ladder bars.

In the meantime, here's a crappy cellphone photo of my rear mounts....

 

I just read through that thread. I can't believe this argument keeps reappearing. To answer your question: I have run this set up for 2 years and it seems to be fine. I'm currntly pulling it all apart to make my rearend changes and so I will re-assess as I look for wear or fatigue on the parts. A theory that I have regarding the strength of the ball and socket relates to leverage. The ball is pushed up into the socket as torque is applied at the rearend but it has a significant mechanical advantage being so far from the axle housing. I have safetys built in just in case but I'm very confident that the ball and socket are up to the task. What I am worrying about (thus the proposed changes) is the flimsy material those rear rods are made of and the old, thin original '48 Ford forgings at the axle end. They take the full brunt of the torque (assisted by my torque arm set up).

Nice idea but I am not planning on a complete re-design / rebuild. That is the set up that I think the guy used on that illusive thread that started me down this path.

Drink up!

Nice work...but not the solution I need for this one.







Above are some pics of what I am currently running. I am getting replies about welding the yoke of front wishbones to '36 rears. That's not exactly what I'm after because it is virtually what I already have. What I want to see are clever brackets that utilise the perch mount from the front wishbones used on the rear axle housing. I know some have done it, and I know I can do it too but was hoping to find one particularly good example I saw several years ago.

That looks good. Is that by Brianangus?

 

Years ago I owned a chopped, Carson-topped 33 Ford cabriolet project. It came with a lot of spare parts including those needed to unchop it and was sitting on a stock chassis. A friend of mine in our car club had bought a chopped 34 5W Coupe a year or two earlier from the guy who sold my car to the owner I bought it from. When we got together one day he noticed the blue goo (gelcoat) running down the firewall of my and mentioned his frame had that same color stuff on it. When I looked at the frame it was in fact the frame which originally was under MY car. It had a dropped Ford I-beam front end with split wishbones and an interesting rear radius rod setup.
A piece of Ford I-beam including the perch/axle bolt holes was cut and contoured to fit the rear axle tubes and welded on. A front wishbone was cut at the "vee" and a tie rod end socket welded into each piece. The wishbones were mounted to the rear "axle" brackets with correct tapered nuts and cotter pins and to the frame rail with a pair of good old Cyclone cast aluminum split wishbone brackets.
I've still got the brackets but didn't get the wishbones because he wanted to us them, just didn't trust that old aluminum.
First and last time I've ever seen that method used to mount rear wishbones.

 

Yup, is that not the thread you were talking about?

 

No. But the guy did something very similar to that if my memory serves me.

 

Looked this morning, ill look again this evening. I just had the damn thing my hand earlier this week.
