Default I broke my truck! Plus some dumb luck.

I took my 41 pickup to a classic car meeting yesterday afternoon. On the way home, I was pulling away from a junction, when suddenly I wasn't. There was an almighty Bang! and no drive in any gear.

I looked to see if I had sheared a key and it wasn't that.

Luckily my friend was with me in another car so he went home to get a tow rope and his other car.

Years ago I snapped the output shaft in the gearbox in Old Rusty and I had assumed that had happened again.

He towed me home on the rope, about 8 miles all along windy roads, lots of junctions, hills and roundabouts. I was braking to keep the rope taut when necessary.

I took the top off the gearbox and found nothing wrong.

I just started to remove the rear end and found that one of the axle shafts was broken. The hub was able to pull out about 9" before something stopped it coming out any further.

What I can't understand (this is the dumb luck bit) is how can I be towed 8 miles home around bends etc without the axle floating out and me losing brakes?

I can't believe how lucky I have been.

Another friend has reported a similar tale where he also did not lose the wheel.

When I broke down I was in a sort of panic survival mode and the thought of a broken axle shaft never occurred to me.

Now I need to see what availability there is of a replacement shaft in the UK.

Wish me luck.

Mart.

One of the reasons I don't use early Ford rear ends. Replacing them is a safety issue.

I made a set of tabs that keep the axle from coming out if it breaks. I think Vern Tardall has them.

Had exactly the same happen to me. 39 coupe just stopped on hill incline.
Towed it back to Westport around 15 to 20 km. Used AA to get the car home on a transporter. Then found the broken axle, LHS. Also didnt move out when towing and no lose of breaking. Made sure the replacement axles were checked and crack tested before fitting.
On checking at axle break it had not been holding on by much for some time.
This was a lucky one for me.
Recently somilar happended to an EFV8 member around the city. He was not so lucky as axle walked out and damaged guard.

Without the strength of the axle shaft to hold it straight, the clearance in the bearing allows some wobble. I wonder if the offset of the wheel in combination with the not so well supported hub tends to create a slight toe in situation. That misalignment might encourage the wheel hub combo to push inwards.

Honestly I'm amazed it didn't walk out.

I'm thinking of making some drum retainer tabs.

Re the axle stand. You'll need to wait for the video to see how I was using that one. (It wasn't to hold the truck up).

Yes, there will be a video.

Speedway has some inexpensive safety tabs

I popped one on my 37 pulling out from a stop sign. The axle broke right where there was a ring wore in the axle from the inner seal.

Smoking gun found.

Stripped the axle out the left side of the casing. The job went well.

Pulled the left half shaft (literally half in this case)

Amazingly it had broken where someone had welded it.

Probably shortened a 46-48 shaft to suit.

Incredible.

The other shaft shows no signs of being welded so should remain.

Good news I suppose.

It's sometimes scary as hell thinking about the "cool modifications" people perform on cars using an arc welder, for instance, like the custom steering components below! DD

A quality TIG welder can weld two steel objects that have some serious pressure on them and the last thing that will give loose is the weld. However... heat can compromise the strength of said item also.


A old arc welder guy might be better then a new MIG buyer/welder.


Those rear hub retains are a decent idea. Cheap to make or buy.

Your statement about a "quality TIG welder CAN...." holds much merit. On the other hand, ol' Mart's axle didn't hold for chit, did it? DD

No it didn't. But we don't know what was done, or how either.

Did a 250 mile round trip today in relatively heavy traffic. Not great fun, but I do have a replacement shaft in hand. So I can now start reassembling it. Luckily I had some parts I could horse trade so no actual money changed hands.

Recommend: Close inspection and crack test of taper and keyway areas at both axles prior refitting.

You can also make your own axle retainers that bolt to the wheel cylinders. These were made of 1/8 inch steel. They are "beefier" than the ones you can buy. However you could buy a pair and then 'beef" them up. Easy to do. Also, follow Richard Crow's advice re: very unsafe 3 legged jack stand. Here's a very informative thread.
