Camber alignment - what should it be

[landshark]

I am slowly dialing in the camber on my 69 bronco and have the spindle shims to do some adjusting. before I took it in for alignment and already knowing the driver side front was out over 1 degree positive I installed that one spindle shim.

The reason I know its out of camber is every tire I put on that front left (driver side) the outside edge of the tread wears faster that the rest. Regardless of axle straightness and in light of my upcoming trip I am thinking I can remove 1 degree + from the front driver and .5 degrees negative out of the passenger side to get somewhere in the ballpark for even wear.

Bronco currently drives great - even with the uneven tire wear before I stuck the camber shim in.

Am I thinking about this correctly? I have read .5 degree positive camber is good on Broncos with D44, 3.5" lift and running 35" BFG's - however i wasn't sure that was total or each side?

So to recap - before alignment I installed spindle shim on driver side knowing there was too much positve camber. Did nothing on the passenger side. Results are below.

How many degrees was the shim and did you get alignment numbers before the shim was put in?

You can rotate the shim to get less camber offset but then will need to correct the toe-in.

The camber shim is set to a bit over 1 degree. I lost the paperwork for the older alignment but have a lifetime at firestone and another appointment for Tuesday morning there to set the toe and take another camber measurement. I leave tuesday evening so trying to set the camber for my 2000 mile trip to not eat any more rubber than needed.


If i set the shim to .25 negative instead of 1.25 or whatever its set at should bring it into spec correct?

I would aim for 0.00┬░ to 0.25┬░ Positive camber on both sides.. If you want to really dial it in, I would set the two sides so you have 0.13-0.25┬░ cross camber bias to the driver's side. This will combat road crown so you will go straight on most roads.

Looking at your picture, you need to dial your driver's side back to ~0.15┬░ positive and set the passenger side to ~0.00┬░ camber. Toe and caster look great.

With the amount of cross-camber you currently have, you should be pulling hard to the right. UNLESS it is compensating for some thrust angle between the front and rear axles. Did they give you thrust angle numbers?

[landshark]

Doesn't pull at all. I have some other readouts will look and see if they included

If you come up with nothing, I would highly recommend a 4-wheel alignment. That will give you camber, toe and thrust angle of the rear axle. (Rarely is a straight axle straight)

Something is going on though. You can clearly see that you have -1.2┬░ of cross camber, which is way out of spec. I would not want more than 0.25┬░ ideally. Either way, if it is driving straight, the front end is compensating for something else that is out of alignment or there is a tire wear issue.

So my driver side ball joint isn't doing so well. I've always had issues trying to get the upper joint into spec. I'm going to try and replace the upper and lower n the driver side before I leave. Might be able to squeeze in a few hours to install. Might have to drive with it as is. Not sure yet. Will tweak the passenger camber Sunday.

[landshark]

Well both ball joints on the driver side were completely destroyed - replaced them today and will take it in on Tue to get realigned and hopefully my camber is close ;)

[Kinder]

Did you check the passenger side?

[landshark]

Yup. All good. I had issues on the driver before could never get the torque specs right. New ball joints went together well and torqued good. Maybe better brand never used moogs. Had spicers before
