How much movement is normal for the front axle of 8n. I read archives but am still not sure if I shoud replace the king pin and bushing or leave it be. I raised the front with a jack and there is no side to side movement but I can move front and back word (tilt) about 1/2 inch. Radius Arms are slightly bent. Thanks for any help.

Yes, you should at least take it apart, and clean it, and then you will know what shape it is in.

If you don't you will always wonder, and not want to take it back apart again to see...

It will be a few days before I get back to working on 8n but thanks for all the replies. I already have all the sheet metal off and being sand blasted. Guess I should just save myself some time and replace king pin and bushing while everything is easy to get to. I will also try to posted method and see what I can do with the radius arms. I am betting I walk away with a black thumbnail or fingernail. Somehow, that always happens. :)

You can fix the radius rods with a big block of a couple of chains and a hydraulic jack.

osduck5;

I noticed you did not get an answer yet, so....for what it is worth, here goes.....

If ya have 1/2 inch of play/tilt, frt. to back, that is way too much movment, in the main axle bore.

I suspect that the axle pin and, or the pin bushing is worn out, and needs replacing..... ..JMO.

This is not a real hard job, and may save ya some $$$'s in the long run!!!!

The bent radius rods,(if not too bent), can be left alone, but I would try to straighten them as much as you can, to insure proper alignment of the frt. axle.

The inspection of damage to the front axle pin and bushing, should not be left unchecked too long, as they will only get worse as time goes by.

When I did mine on my 2N, I found a lot of damage done by the worn axle pin and bushing, to the axle support bores, and had to have the support, built up by a rep. welder and line bored.
All told, new pin, and bushing, and replacing all the front axle bolts, and having the damage corrected, ran me close to $200.00. Had the pin been fixed properly by the prev. owner, it would have been much less cost.

This is a pic. of how I dissmantled the front end, and shows that I removed the hood, radiator and rad. fan.

All total in time, from start to finish, it took about 3 hrs. of my time, and 2 1/2 hrs. of welder time. All this was due to, letting the repair go too long.
