Front Camber and Caster Out of Spec

[GJC501]

Hi,
I drive a ‘21 JT TX Trail, drive train stock, and I have not taken the vehicle on any “rough” roads other than well maintained county gravel roads—mainly driven on Hwy asphalt.
Got it this morning to an alignment shop, where I was told the front camber and caster were out of spec—toe spot on. Driveline was also off.
Got my MT tires rebalanced and rotated and the driveline corrected, but the camber and caster couldn’t be calibrated to correct the slight pull to the left I am experiencing.
Within these few lines, I am sure most of you have noticed I am new to Jeep JT.
I was surprised that the manufacturer’s control arms are “fixed” and cannot be adjusted—to be expected on a $15k car, not on a $45k vehicle.
The mechanic recommended I took my JT to an FCA dealership for warranty work.
Well, here’s my dilemma: I am wandering what FCA “experts” will do for me, except immobilizing my vehicle without fixing it, until I get them to do exactly what’s needed to be done.
Now, my question is: Is it possible to loose these fixed parts and get the front axle to align to specs, or am I in for replacing them with adjustable ones?
If so, what are these parts I need to consider replacing (Tx Trail/Willys stock height), and what is the ballpark cost for the upgrade?
Thank you for your constructive suggestions and recommendations.

What are your caster and camber numbers?

 

[GJC501]

Camber Front Left: 0.1
Camber Front Right: -0.6
Caster Front Left: 5.1
Caster Front Right: 5.0

Honestly, caster numbers are pretty good for a stock JL/JT. Front left camber is ok, front right is probably a loose balljoint.

Checking the balljoint, is that something I can do on my own? If so, how can I do that?

I would check which Jeep spec that alignment shop pulled from because your caster is within factory spec for the gladiator.

Absolutely. Rent or buy a torque wrench, and buy replacement cotter pins. Fighting with used ones isn't worth the hassle. 2 of mine were so loose I probably could have removed the nuts with my fingers.

Where can I find the torque at which I need to set the wrench for the balljoints?

Are these the correct setting?

I didn't see the ball joint specs on there, but I didn't read through it...

Top ball joint: 52-59 ft. Lbs.
Bottom ball joint: 30-37 ft. Lbs.

If you have to go a little higher to get the castle nut aligned with the hole, don't stress. Just don't go full gorilla on it.

Thank you so much!

Nothing wrong with those numbers IMO other than caster being a little low if you're lifted. You generally want slightly more negative camber or more positive caster on the passenger side to compensate for road crown. Normally caster is preferred because less tire wear but half a degree camber isn't going to cause that.

I'd re-torque your ball joints as others have said but I wouldn't sweat those numbers.

i would check the torque on the tie rod ends and drag link also.

It's right where I wish mine was. I'm at 4.5 and when it's warm will put on the MOPAR lift lower control arms.
I agree - that shop guy needs to either relearn the machine or look at the specs again.

You would want front UCA’s if you want to change your caster angle. I’d invest in the adjustable UCA’s from Clayton. I went with their measurements for their UCA’s to the T and came out with a 4.9 caster and I didn’t even adjust my pinion yet. They recommend 4.8-5.5 degrees caster (with a 2.5” lift). I might mess with them in the summer and shoot for 5.5 degrees, although it drives amazing now.
