Replaced steering, now much stronger wheel feedback

That's a little high for 33s, but probably not enough to cause your problem.

Toe-in is not measured in length, it’s measured in degrees (or radians if you’re a weirdo).

Tell my tape measure that.

Mine looks the same as yours except my stock track bar is cleaner.
p.s. I'd drop your tire pressure to 26 psi.

Pop quiz! I hope you've brushed up on trigonometry recently.

1. Bob measures 1/8” toe-in following the method in your picture, but does not know the tire diameter because he is an ignoramus. The toe angle works well and he would like to replicate the results on his rig with 40” tires. How much toe-in, in inches, should he aim for, following the same method, to achieve the same toe angle on the second rig?

Good thing Bob didn't align mine 8 years ago or my tires wouldn't be wearing perfectly even. Even better, that I'll never have DDDDs. My wife has DDs though. They are wearing a little unevenly.

Just checked angles and I’m not sure based on these angles if I need to get adjustable control arms. This was a 4 inch lift kit that I measured out from rough country.

So a digital angle finder is relative to what you zeroed it out on...I probably would have started the pictures with you zeroing out on the ground or the frame.

Without reference to what zero is the numbers are related but arbitrary.

The 5.65 number picture is where you check castor and typically you subtract 7...I might need to do some searching to confirm this. I believe mine was 12 giving me an actual of 5.

The concrete surface was .25 degrees when i zeroed the gauge

Thread 'Caster adjustment advice?'

Feb 7, 2024

Hey folks. I was looking to dial in my caster a bit last night because my steering is ok, but "light" doesn't really return to center as I would like and came away with questions vs a done task. Setting pinion angle on the rear was easy because the diff has flat spots on the back to measure the angle. I thought I remembered someone telling me there were the same kind of flat spots under the C's to check caster angle, but I did not find them. Could be I just don't know what I am looking for. What I found was a U shaped area with a depression in the middle. I could bridge the sides...

It says pinion degree -12 gives you caster.
So, 5.65 -12 = 6.35 caster.

Not super low, but I think Blaine explained to me when I was doing this, number doesn’t matter.
Adjust until steering is good, then check for vibes. Then you have to decide depending on how things on your TJ are reacting.

So just adjustable upper control arms should get me where I need to be correct as the lower control arms adjust the placement of the axle in the upper control arms adjust the castor
