Has anyone ever had a bent half shaft? I was getting a odd wobbly feeling in the passenger side rear of my spit. Took it to the shop they told me I had a bent half shaft. I asked to give me more details. I was told the tip must have been bent when the prior owner tried to replace my wheel bearing. Anyone else run into this?

Christopher,
I have had multiple bent axle shafts. Some near the end, others closer to the middle. It can damage the trunnion bushings and if in the wrong place the wheel bearings too.
All the best,
Paul

I have chased this issue for some time now. I had grease in my break drum, I replaced the seal, I had a wobble, I replaced all bushings and shocks, I had a wobble, I replaced the bearings, I had a wobble, I replaced the ujoints, I had a wobble. Took it to the shop they said bent hub plates, someone trying to do the bearings wrong tool blah blah blah, replaced the plate, took it for a test drive and now bent axel. So hope this fixes it. Won’t know for sure till next week.

Bent axles/hubs are not unusual, due to striking curbs, crashes, or improper axle disassembly using wrong tools/techniques.
The axles are not any special alloy, only hardened on the needle bearing surface.
They can be straightened by specialist using a press, ad lathe to check straightness.
The hubs are also nothing special, save the machining of the taper.
If bent, they should be discarded and replaced.
Both parts are available new, at reasonable cost.

Only about 50% of first timers actually get a rear axle repair done successfully.
(simply getting things re-assembled does not equal successful repair)

If you are into longevity, check out Mike Stefanakis' (handle Hot Spit) axle upgrade, that fits a larger renewable needle bearing and inner race to standard axles.

I had new ones ordered, didn’t want to have them try and straighten them. I wanted piece of mind knowing they are good.

I would not simply take the word of a shop that it was 'a bent axle' without actual proof.
Particularly if they said the axle got bent during disassembly, which is a bunch of BS.
The outer drive flange (FAM2004) is what get's bent, not the axle.

Did you also order new outer drive flanges?
It's a good idea to replace the bearings and seals too.

Replacing the axles requires complete disassembly.
It is essential that a proper tool be used for disassembly (search for Churchill tool here).
Else the axle flange will get bent, and require replacement.

Christopher,

If you are willing to send me your bent axle I will check it to see if it is salvageable. If its not too bad I'll try to straighten it and post photos on this thread as I go along. In any case I will return it to you. Nothing ventured nothing gained.

Most likely just the hub bent. CAUSED BY WRONG PULLER.

If you feel like driving North, I've got a proper puller. I'm in Columbia Station.

Bent hubs are much more common that bent axle shafts, for obvious reasons.

I purchased a new 1974 Spitfire 1500, It was loud and like Vibram massage machine. Took it to the dealer with around 500 miles on it. They showed me that my drive shaft was bent from the factory. There was not a driveshaft in the USA. So they ordered one from the UK. It took 4 weeks to come in. I asked if it was shipped by roow boat., the parts manager did find my humor funny. The car also came with a chipped revers gear with same story on the gear availability. Next was a broken second Syncro hub. Again the same story on parts and shipping. I owned my Spitfire for 6 months,but was only able to drive it for three months.

None of that stuff 'just happens'.
I'm guessing that your car was far from new … childs play to disconnect the speedo cable and render the odometer useless.
Meanwhile, sounds like maybe the dealership owner had let his kid drive and thrash the car before he flogged it on to you.

This!

Alternatively, it could have been a new car that suffered under the hands of a careless "prep" guy. One of our local Albany area dealers happened to be literally just a few doors up from a commercial car wash (both on a very busy commercial thoroughfare), and new cars often were, uh, "driven" there by the prep guys for a final wash before delivery. In at least one instance, one of those guys managed to just about total a brand-new Spitfire on his way to or from said car wash. Unfortunately, that obviously resulted in one car that could no longer be sold as new. Fortunately, for the car, damage was mostly limited to the bonnet and other bolt-ons. I saw it soon after the incident at a local foreign salvage yard, where the gang was fitting another bonnet, etc. I'm pretty sure that prep guy lost his job. winking smiley
