Can you adjust camber on a solid rear axle

[luc]

Obviously more of a general technical question than s550
What do you think?
Key word here is adjustable

No.

Why would you want to?

Are you sure ?

The only way to get camber on a solid axle is to bend the tube. Due to the bearing you are limited to about .5 degree if you want it to live more than a few miles.

I think Smokey Yunick was the first to do this to get an advantage in Napcar.

Hello; I agree. Knew NASCAR teams did it. As you say limited. Did not know it was Yunick who started it, but he pioneered so many things.

I've never tried it, but have heard of it being done.

Unless you're running an oval track, I don't see the reason to. Ford's former 9" rear differential was basically bullet proof and great for drag racing.

So, my old race car, a 1989 Mustang Trans Am built by Jack Roush, pictured below, had rear camber that did not involved bending axles or extra load on bearings and my recollection was about -1.5*
here how it was done:
First the car had a full floater rear axle, for people that don’t know what it is, it’s simply a system where the weight of the vehicle is 100% supported by the axle tubes and none by the axle shafts, therefore the “full floater” term
The wheel hub/stud assembly was mounted to the axle flange with 4 bolts BUT, in between was a spacer that was machined with a taper shape, meaning 1 end was thicker the the other one. That created the camber for the wheel and because it was a full floater the splines could work at a small angle…
Pretty smart engineering and really show how good Roush was

You said adjustable.

That's not adjustable. Machining in a taper is not being adjustable.

Hell, I did something similar with my Xr4Ti, so it's not rocket science.

Adjustable because was different shims yielding different camber gain
Since when did the xr4ti had a solid rear axle
Comparing apple to oranges

I figured it was no longer bending the tube.

Thanks for showing us how it is done.

I was confused by the word "spacer" instead of "different shims".

I'm just saying I adjusted the rear camber on my Xr4Ti with the same concept; spacers between the wheel hub & flange.

Xr4Tis had an issue with the LCAs bending and creating bad negative camber, so that's how I fixed it.

If you already had an answer that you were self-assured of, why did you even make a post to ask the question? Did you want to prove how smart you were to the rest of us?

Smart????
I’m not the 1 that came up with the idea and realized it…what’s your issue? Did you knew that it was possible?
If not, you have learned something…
