The spindle is pretty much the same as Aaron shows except the pins are straight and part of the axle housing.


Spherical roller thrust bearings are used instead of straight tapered bearings. I guess that allowed for a little misalignment.


Thanks for all the insight but at my age I guess I’ll live with the problem as I have for 50 years.

The trunion pins at top and bottom of the ball/knuckle are tapered, if that is the axle I'm thinking of and there are shims between the caps and ball, this is a jeep front axle, but Dodge used the same setup on the command car and M37's if those are worn then your camber can change.

I can see where if you hit something (high centered) with the axle housing at speed, it bending, just about any other way (overloading, air drop etc) would bend it the wrong way for what you are seeing.
 Trunnion wear will also show the other way to what you are seeing.
 An axle housing that the locating "pin" is knocked off can put the front axle out of true and still be set to correct toe and caster. You need a datum point on the frame on both sides and a trammel bar to check both the front and rear axles.
 If you are sure about your 1/8" then it does look like the axle is sprung a bit.

I used two methods to compare the camber of both front wheels. The first was to compensate for the floor which is flat but pitched to a drain by 1/16”/Ft. The other was to compare to a plumb state. Both indicated the left front was perpendicular to the floor and the right was pitched out 1/8” in 24” at the top. The toe-in is 1/8”.

Right front.


Left front.

Plumb check.


I'm beginning to agree with Dan and the rest that the axle is bent in an unusual way with the end bent down. Probably when Uncle Sam had it.



Tony

Dan I think you got it. Something definitely bent. Aaron, Good advice on checking alignment. I too learned that from an old alignment man who is no longer with us. Geoff, yes there are pins to wear or bend but I always thought that caused wear on the inside edge. Going to be interesting to find out and maybe learn some thing new.



I cried because I had no shoes till I met a man who had no class.

Yes, I thought he checked that, but I see he just checked the toe-in. Those 4wd front axles have trunnion pins at the top and bottom of the ball joint, but when they wear the inside of the tire is the side that wears. 
 Bent parts are always something to check for.
 I have a problem with the Marmon drive axle alignment, and it tends to wear the outside of the front axle on one side long before it shows on the tire on the other side  Much time spent on front end alignments  didn't solve the problem, It wasn't until I got deep into the rear suspension did I find the problem. As the truck gets pushed sideways down the road, the tire on the outside wears faster than the one that the inside is being dragged. 
 I don't have the answer only a suggestion on something to check.

Tony, just my two cents worth and it's probably not worth that that. I would check the camber and also the toe in both. Maybe a bad king pin or bent axle on the right side.

Dan Cornett

If the rear axle was out of alingment I would think both front tires would show wear as the front wheels need to compensate for the rear dog tracking, I would guess camber also maybe the top pivot pin on the axle is worn.
 Lesson I learned several years ago about front end alingment, disconnect the drag link and turn steering box lock to lock and then find center, set the sector arm straight down, set front left wheel parrella to the frame and then set right side 1/8 in, this from an old shop in southern Ca, check front alingment going by this method and see if its way outa wack.

If a lot of towing is involved, it could be the fact that right turns are tighter than left turns.


Jim

Roundy-round cars have that problem too, but probably a different cause. :D
Have you compared the camber on each side?
