Front Tire Camber.....Question

[islandguydon]

I drove the Oddball Express M-109 from Florida back to Michigan a year ago. The front passenger side tire was 1/2 worn on the outside half. The camber is off. Since the M-109 is up on blocks to be painted I figured it's time to fix the leaning tire situation.

My question is this; Since there is no adjustment for Camber I feel the Kingpin upper and lower bushings must be worn. Am I correct in saying the only way to fix this is to replace the Kingpin and both bushings...?


Any help would be appreciated.opcorn:

Don,
Is there play in the bushings? If not,
That was a lot of highway miles, in the right lane with extra weight on the right front due to road sloping for water run off.
There is also the possibility of the axle tube being bent, welded on a little crooked, etc.

More than just camber could have caused that. Toe could have as well. And toe is far more likely.

Bite the bullet and either take it in, or get really creative with some boards, straps and a laser level. Camber is easy to diagnose , as is toe. Castor requires a "swing".

If you decide to check it out yourself, make a thread out of it! Lots of pics!!!

Could be that the toe in is out.

From what I have been told, wear on the outside of the passenger front tire is normal and the best way to deal with it is to rotate the front tires side to side to even out the wear.

That is what Jatonka told me and I have checked my toe in and it was in spec so I play swap the tires a couple of times a driving season.

Toe is going to wear both tires, Not just one...........

Thanks Bob, It was wearing a tad bit at the GA Rally and Phil said it would be bald when I got back. He was right. How much play is in the bushings surrounding the King pin..? Does anyone have a front Axel diagram for a 70s deuce..?

Don, You should have Zero play in the kingpins. The wheel bearings are tight right?

Now that I have it in a heated shop and up on blocks I am going to do the best I can to fix this myself. Bositck GMC is the only place around that will get it 100%. The problem with them is its $500+ every time you bring anything there.Get my point.

Spec is very slightly toe-d "in"... When combined with road crown, you will only wear one of the two tires... probably the passenger, because you are always turned slightly "left." The rh wheel is the one being slightly scrubbed when you're traveling "straight".

The more it is toe-d in, the greater the scrub.

As Heath_h49008 explained... the front pass. side tire simply "works harder".
Im sure in UK it is the left tire that wears faster.

You can't check this stuff, with it up in the air! You need weight on it, to get it right!

On a good flat floor, lean a Framer's Square against the tire. A quarter, to 3/8" space at the bottom, is just right. That is from the top of the tire, to the floor! Unles you have wear, you can't adjust it.

Most likely, the toe can be out. I used an old pair of truck wheel bearings, a cone and cup, withe a 6" square of 1/4" plate tack welded each to the cup and cone, so the tire can sit on the bearing with the weight of the truck on them. Jack up each side and put one of these swivels under each steering wheel. First though, scribe a center line around the tire, by rotating the wheel, while its in the air. Then get your assistent to hold one end of the tape, and do the measure, front and back, half way up on the wheels. Zero to a 1/4" is OK. Maybe a little more. That's closer in the front, then back. You can adjust the toe, with it sitting on the little bearing platforms, and not have to move it, till you get it right.

Its really, pretty simple stuff

The spec and adjustment for toe is in the TM 9-2320-361-20, pg 9-12. The steering knuckle check is in TM 9-2320-361-34, pg 10-40.
