Does that wheel look a little funny to you?

So you’re gonna get 2 spindles
Looks like it, cause I can't find just 1 for sale.

Like I said, I had just done the front-end last summer, so unless I really screwed something up putting the new rotors on (but i dont see how) I haven't a clue what else could've caused this.

check it out...


i don't know what your situation is, but that's an option...

but like @72bluNblu mentioned, out of an abundance of caution the best move would be changing everything and giving all the bits the hairy eyeball.
 
BTW, go back and find the parts!!!!!

Another thought....

What if the nut came off, the brearing and washer popped out and the end of the spindle became the bearing surface with a bunch of bending force up, and the spindle snapped?
 
Outer wheel bearing seized and spun off the end of the spindle. Cap still on and welded bearing still in the hub.
Definitely seized bearing. Put your hand on the dash pad while driving and if there's a vibration, it's a front wheel bearing. When I was young and dumb someone told me my wheel bearing was going. A week later same thing happened. Spindle snapped. Drum car lost the whole drum and tire. Luckily, I was on a side road. Great time to do a disc conversion. lol

There's a 440 in it, the whole car vibrates lol.

I could try to find the missing parts, but it's unlikely. It's a busy 50mph 5-lane road, I can't quite just walk down the middle looking for a nut or people will think I'm the nut.
 
Most of what I find say its for cars with 10" drums. Can anyone tell me if the spindles and wheel bearings were the same on cars that came with discs? I think they are but want to be sure.

Bearings and seals, 10" drum and disk use the same. ( At least to 72)

Spindles are different due to caliper mounting.


Get out your parts book for ( I'm guessing 73)
Look up bearings section 22-06-01

Listed are the factory part number for the inner and outer A body (V,L) bearing sets.

All car lines with one exception use the same inner bearing 3744 975

And for bigger than 9" brakes (ie 10 " drum and disk") A body use outer bearing 9744 924.

Then go to rock auto and search the OEM part number to find the cross reference.


Inner (different than 67- 72)

Outer (same outer since at least 67)

If you don't have the factory parts book you can download it free at mymopar.com



Btw this approach works for all kinds of parts.


It would have been nice if they listed the bearings at 10" drum and disk in the FPB but they did not.

These are 73+ disks, which is obvious from the spindle. There is no reason to muddy the waters with drum parts or anything pre-‘73 because most of it is different.

‘73 up used A17 inner bearings and A2 outers. But again, DoctorDiff has all of these parts, spindles, rotors, bearing and seals.
 
I did the front suspension last summer (shocks, ball joints, tierods) but didn't replace the bearings, they seemed fine then.
So on the damaged side (driver), the inside of the rotor is marred so I'll be replacing that again. Since I just replaced them with the brakes last year I should be fine only replacing the one side.
Am I reading this correctly? You replaced the rotor hubs and reused your old bearings from the old rotor hubs in the new rotor hubs? If so this is a huge red flag to me. In doing this you would have mated older worn bearings into brand new bearing races. This is not a practice known to have long lasting results and is not practiced due to risk of bearing failure from different wear patterns between old bearing and new race. The new bearings would have cost you about $40…

And before anyone says it, yes, you can reuse old bearings if they are good but you must take the races with them. And most times the race is damaged during removal.

Ummmmmmmmm yes that's what I did. The bearings seemed fine and I repacked them with fresh grease. It's what we did in the army, we didn't replace the bearings every time the hubs were removed.

how many miles ago was that?
(sorry if you said it upthread i missed it)
 
Wheel bearing maybe
Spindles no
I just did a conversion last year, from drum to disc on my 69 and also the lower ball joint were different, but I drilled out the attaching hole for it to work. I have heard of people using a wire instead of a cotter pin on the nut. Bad idea!!!!!
 
They wire tie everything on race bikes...or did I have a wire tie tool. Not zip ties
 
I should have the spindles tomorrow, I've got the hubs and everything else today. I also had to order a gas cap (totally unrelated). I have a bad habit of setting the cap on top of the pump then driving away. This last time I didn't even noticed until this incindent happened and considering I haven't been to the pump in over 2 weeks, I'm pretty sure my cap is long gone. After checking around, seemed like OER was the only one who makes a reproduction and it's about $50 no matter what site you look at. And jegs wanted $15 to ship it on top of that! Then I came across Auto Parts - OEM Replacement Car Parts from Leading Brands | Sixity Auto and got one for $11 with free shipping.
