1972 Highboy Build Progress

Once I did the search found some good info.
I have the right side down to the knuckel. Inner bearing and race bad. Seen worse but it needs a new set. Looks like it was hot at some point. Outer bearing was good and no hot marks.
The closed knuckel needs some fresh oil. Going to use 140w gear oil when I fill er up.
Going to check differential tomorrow as well. Might go all the way and take out right axle to check everything and put a new seal in. So looking for info on the front axle tear down. I'm this far, why not. Time and tools with some skill and help - all things are possible!
Thxs -
Best to pull both axles then if you still think do I really want to do this to a drum front axle with very few reproduction parts. But no replacement axle are being made.
Mine were bad, one slightly bent with both having deep groove in them from the inner axle seals warn in to each the seal areas.
So fixed mine all up then a yr later picked up a 76 disc axles reworked it and could not give my old one away so junk it with rebuilt backing plates all new bearing, brakes & cyl.
New tie rod oh well. Only money spent about a 1k on it.
Went into pnp junk box after putting the disc axles in.

Roy will help you out and I know that because that's where I got the parts for my 6CF. Only thing to be wary of is the drums which they don't have. I had a tough time sourcing mine but did finally get them.

But no new axles for the 3000lb axle then, but got everything else.
Looking for some parts were like chasing the rainbow.
One ford dealer had two new nos backing plates in there inventory
but could not find them. Parts man said they must be in the basement.
He did not ever find them with in a mouth so had mine welded up in the brake shoe pads an a friend milled them all even. Just like new after that.

Thanks!
Pull the axle out and try twisting the short axle back & forth while holing the long end steady so it won't move. You can inspect the inner axle end seal area for roughness or deep grooves.
Baja is talking about the ball movement if it has up & down movement then the king pin blocks bearing may need replacing. There is shims under the king pin on top. You just use a inch lbs TQ wrench no big deal once you understand an see them.
I setup mine with out a inch lb TQ wrench just light side to side movement, not to tight that's all.

You can check the 'play' in the hubs to ball, by trying to move the hub up and down. If there is any play at all, then I would pull the pinion caps, and check the bearings. Top one especially, as it gets the least oiling, and the bottom one, because that is where water will collect, and of course, rust follows. You can do them one at a time. The shims, are various thicknesses, so I usually assemble the hub without the shims, tighten the 4 bolts on top & bottom, then with a feeler gauge, check for spacing between the pinion block, and the hub top.. Add the shims to account for the space, and torque it down to specs. Then check the hub for up & down movement, and feel how tight it is for fore and aft movement... Oh, with the wiper seals installed for the check. If you have all the bolts torqued, then with an inch pound torque wrench, try tightening one of the top pinion block bolts... the hub should move smoothly, in its fore and aft arc, with 12 inch pounds or less. You are not torquing the bolt at this point, only checking how much force it takes to move the hub. It does not want to be too lose, nor too tight, just snug enough, so that it moves freely, but not loose.
Now, all bearings 'wear in' just a bit, so it is a wise move, after driving a bit, like 50 miles or so, jack up the front end, and check for play in the hubs, and wheel bearings. Might not be necessary, but it cannot hurt either. I always check the lug nuts too, after a short drive, just to make double sure that they are all torqued to 100 ft. lbs. at least.. Loosing a wheel has happened to some, even after leaving a tire dealership... As the saying goes, an ounce of prevention, is worth a pound of cure..
Merry Christmas amigo, and a Profitable New Year...

Everything looks good. Oil is very low but no water in it. But I can move the axle left to right and up ans down maybe 1/2 inch. So in this pic... where the short shaft is seen... I can move that, so what is behind the U-Joint looking at this pic? Is the play normal? The U-Joint is in very good shape. So, I'm thinking I might not take the steering knuckle apart becasue it is so good. Remember 42k of the 65k miles are long hunting trips to Canada and Colorado.
I had to be a little creative in order to free the differential cover. Glad I did, because the oil had water in it. Maybe 8 to 12 oz. Everything inside looks great. I will clean the gears with and put fresh oil after I do the other side.
So the oil looks nasty but the gears look good. Also the oil level was right at the fill line. I checked before dropping the cover. What is the best way to clean up those gears? I'm thinking break cleaner.

The steering knuckle (if I understand what you are saying) has "0" up and down movement. But look at my question about the axle shaft having some play in it after I removed the hub of course. Is that play correct? The knuckle is so good on the right side that I'm going to stop here and start to rebuild the right side unless that play is not normal. It has in and out play of a 1/2 inch as well. So the axle will move toward the differential 1/2 inch and back. The axle will also move left to right and up and down about a 1/2 inch or less.
In trying to help give more info, i did this just now... looking at the axle with the hub off and rest of knuckle still on... I took the axle applying pressure in one spot going up and moved it around the clock to see what I would find. So I found the spot that it had no movement and marked that as 12 and then moved the shaft around the clock to see what I found.
At 12 oclock no movement going up and axle would slide in and out.
1 and 2 oclock with same results but it was starting to have maybe 1/8 and was grabing like there was an edge on the shaft.
Then at 3,4,5 the play increases to 6 oclock being the worse play with maybe 3/8 at the most and a clear lip grabing the axle.
Feels like there is a bad spot on the axle?
Then going to 7,8,9,10 was the same but the play was less and less until 11 oclock where it evens out and had maybe 1/16 play and would slide without hanging up.
I hope that made sense...
What do you guys think?


Thanks again!!
