    Does the car have a one piece or two piece prop shaft? Might also want to give a closer look to the trans extension housing bushing and slip yoke. And maybe even the pinion and differential side bearings. Stranger things have happened. Did this car originally have any kind of a bob-weight or dampener on the end of the trans or the front of the rear axle pinion housing?

    I checked the yoke and output bush when I did the UJs last year, it’s a one piece shaft and I don’t think there’s any sort of dampener.

    That wheel bearing will give you a lot of vibration, as the speed increases. Imaging how rough it must be with the weight of the car on it, and how much it can move on the axle shaft under a load.
    I suspect that replacing the bearing (and possibly that axle shaft) will reduce or eliminate your vibration.

    I can’t believe how much movement there was in the bearing when I’d got the axle out yet so little when trying to rock the wheel. The inner race is solid on the axle, thats play in the balls. So hopefully the axle is still good.

  6. I did that once. No vibration, it just all came apart when a new u-joint decided it didn't like it's job. Even in 1969 all parts weren't created equal.

    Ive right royally ****ed up, I cut into the axle shaft removing a bearing. So am now on the shop for a pair of axle shafts. I am however struggling to find anyone who does an off the shelf replacement. :(

    How deep is the cut? Post some pics
    I know it’s probably posted somewhere in this thread but what rear axle do you have?

    Stock Monterey/Galaxie small bearing Ford 9 inch.
    It’s in just the wrong place. I’ve been racing for too long and seen too many wheels disappear into the distance due to broken axles to risk it!!

    I agree if the cut was length ways and shallow you might be ok. That cut is in the worst possible place IMO. Are axles hard to come by in England?

    The only people who never screw up are people who never do anything. Welcome to the club.

    They seem to be hard to come by everywhere, none of the suppliers in the US seem to have anything either. All the off the shelf 28 spline small bearing axles seem to have a 2 1/2” offset from bearing to brake surface where as these are 2 1/8”

    I’m guessing I’m going to have to go to a custom job from someone like Strange.

    When people say to me “how did you know that?” I always reply “because I’ve screwed up before!”

    Ah man that's so frustrating!!!

    You'll be using heat to free off the other one I ***ume ;)

    There's a fairly active UK Galaxie group on Faceache if you're brave/desperate enough to ask for an axle there.

    I had a torch on it before I tried to cut it and it wouldn’t budge.

    England has a max speed of 70 and 7,000 cameras to enforce it. Never fear many have been cut down by locals not happy with big brother watching them.

  19. I've been there. Took a few years for me to realize that when that happens just go away until you can touch it by hand again. Make sure the axle is supported in such a way the the weight of the bearing will help itself just drop off the axle when it gets hot enough. The axle shaft, below the bearing, should be polished clean and be dry. Make the torch as hot as you can and heat the bearing race as quickly as you can. A couple of bearings have made me go back a third time, but there is so much joy when the race just up and falls right off the axle. It's almost like magic, :)

  20. You plan on racing it? If not, I'd be sorely tempted to 'blend' that with a 2 or 3" sanding disc, say 300 grit or finer to remove any stress risers. I've found worse than that a few times changing bearings, worked fine on street cars. I've had plenty of failures with those axles, but every last one was twisting the splines off at the differential. And that was big power in a heavy car with a manual trans.

    And how hard was it to pull the axle? Need a slide hammer, or did it pull out by hand? These housings have been known to bend, and if you need to really beat the axle back in, bearing life won't be good. The usual fix is to cut the ends off, then weld them back on using a fixture.

    Don't know what's available there, but there is a couple after market suppliers on ebay that offer different custom cut to length axles that are 2" offset that come with a 1/2" press on spacer that could either be cut down to 1/8" or just machine a new 1/8" spacer using the 1/2" spacer as a pattern.

    Probably be a lot cheaper than a custom made one and I'd have to problem pressing a spacer on one and using it. ..

    I did use a slide hammer but it was easy. No racing but I’d have to remove quite a lot of metal to get the cut out.

    Thanks. I might have measured it wrong: i measured from hub face to bearing face which I now think includes the back plate which it shouldn’t, still won’t be 2.5” though.

    Tim, give Hausers a call for the halfshaft.
    Friend of mine has a '59 Ford station wagon that decided it didn't need the drivers side rear wheel anymore. On his way to my place one evening, it made a break for freedom as the 'shaft just broke right at the bearing.
    You can imagine the fun we had rescuing him off the side of the road.

    Thanks, will do.

    I thought as they made millions of them it’d just be a case of going online and clicking!!!!

    Ford did make millions of them, but 60 + years has a way of reducing the number of good ones left.

    I’m looking for a good international answer.
    You must have little nuts if you have a vibration at 85 mph and it slows you down.:(
    Here in the states, it takes big nuts and we just speed up to 110 mph and eventually it smooths itself out.

    Just kidding, just kidding. :D

  28. Unfortunately, Ford changed the track width almost yearly so there's a bunch of different length axles. Also keep in mind that the 8" rear also used small-bearing 28 spline axles and there is some interchange depending on vehicle.
