Don’t let this happen to you!


We hate pictures of accidents, but sometimes they serve as a warning to all of us. This is what happened to John Vahey and his friend when they were touring with John’s 1910 Model T. Suddenly the front stub axles broke and both John and his friend were thrown from the car. They suffered minor injuries, but we are happy to report that they are alright by now. The stub axles had been welded before John bought the T and later obviously cracked. John has since found an original set of stub axles and is already working hard to get the T back on the road. If we hate this kind of pictures then why are we showing you this? Because we recently saw a similar accident when the T of Dirk Regter broke down in Malawi with a broken kingpin during his World Tour. And also in the past this wasn’t an uncommon problem. We’re sure there are Model T experts among us, who know this problem and will be happy to share with us how to prevent this happening! And keep in mind, it's not only Model T's that can suffer from front axle issues...

When you look at the broken front axle you notice two dark sections. To me it looks like it is not welded 100%, but only circumferentialy with a depth of circa 5 mm.

Please note that it looks like the weld is not 100%. At the top and bottom section of the broken axle you see a dark area. Has it been welded with a circumferential depth of only 5mm?

May I remind all that a part that has not failed during a period of over 50 years is very unlikely to suffer fatique failure ever.
Of course this does not apply when there is accident damage, earlier repairs or an increase in load.

Hello Prewar,
Doug Langevin has got it pretty well right. The 'one piece' front axle fitted by the previous owner was purchased for him, at a premium price, in 2005 from Hershey Auctions. Even several UK MOT's failed to spot the 'adaption' because the welding was deliberately & so well disguised with filler & paint. A slightly later period two piece front axle has now been tested and fitted. Hopefully airing this incident will help others be wary. I & my passenger were very lucky to have survived. Car rolled and caught fire. Also always have a fire extinguisher to hand. 1910 T Tourabout is now fully rebuilt & ready, as I am, for the 2013 events. Regards, John.

Following on from Doug Langevin's comment-if another vehicle was involved, would the insurance company have paid out? Maybe the (now voluntary) annual MOT test in the UK would have failed the car- so it would not have been on the road in that state.....in the UK at least.

Mr. Langevin is correct. This is a criminal act. Axles in the USA are so common in good condition one can be given one. This car also has the early radius rod above the axle. It should have had the reinforcing brace below the axle also. They should not be operating vintage automobiles.

In the late fifties I was driving myself and some fellow students in my 1936 Morris 12 between Wootton Bassett and Harwell in Berkshire when the offside front stub axle snapped and the wheel and brake drum fell off. The car dropped down onto its built in hydraulic jack (Smiths Jackal) and, out of control, with no brakes and very ineffective steering, slid conveniently into the forecort of a garage. A friend travelling some way behind stopped, looking very pleased and told us that he had found a wheel with a nearly new tyre in the road, and that it would fit his car. I reclaimed my property and the next day,having acquired a replacement stub axle from a nearby scapyard I fitted it to the car and drove back home. The gouge that the jack left in the road was still there ten years later.

In early 90's I was halfway the Alps with my '35 Singer Le Mans when the securing-ring inside the backaxle broke and the halfshaft came out of the backaxle, result was no working gears, no clutch, no brakes: nothing! These few minutes coming down the mountain with screaming tyres, avoiding a disaster and by pure luck, rolling into a small village between two peaks I never forget!
Later we found out that the metal ring was homemade from some fruitcan instead of a forced steel example. So never trust the work of a friendly but very old pre- owner :-)

Lesson learned long ago from racing, always crack test any safety related suspension bits. Regardless of who you got them from, or what the prior owner tells you.

The broken axle on Mr. Vahey`s 1910 Model T Ford was a re-worked 1911 or later original Ford production forged-steel " two-piece spindle " axle that was modified ( " restored " ) to appear to be a correct 1910 " one-piece spindle " axle . The spindle yoke ends of this axle were sawn off , and newly-made " replacement reproduction " cast-steel axle ends were welded on , to make the axle resemble an original 1910 " one-piece spindle " axle . An original Ford-made forged-steel Model T axle of ANY year would not , and COULD not break like this unless repaired or modified in this fashion . The use of ANY axle on the public roads , so modified , is , in my opinion , almost a criminal act , endangering the occupants of the car as well as any bystanders , as this one has proven .

what i see here is a broken frontaxle not stubaxle......never use a welded axle when so many used parts are easily available. yes king pins do break but also but rarer on a model t stubaxles. bigger problem on t's is the babbit bearing taking the crownwheel thrust. they tend to crack away due to age and be better replaced by a bronze bearing. if the crownwheel is pushed away because of trustbearing failure you not only loose drive but also your brakes.......also check your wheel spokes on a regular base. model t's are otherwise extremely tough and long lasting.
