Loose steering feels like it has play and drifts

I'm to the point where I'm about to give in and buy a PSC overland kit. I have a Metalcloak GC and 37s on my JLUR. The lift helped with the steering due to the added caster. I have added SS drag link and tie, and a synergy track bar and sector shaft brace. It's about 70% fixed. It still won't drive straight down the road. It has about 2 inches of play in the steering. My wife won't drive it and wants me to get rid of it. So basically it's sell/trade it in and lose at least $10k with all the stuff I've added or spend another $2500 and hope that fixes it. I'm also considering a heavier rear sway bar. Any wind over 10 mph or passing a semi makes it almost impossible to drive on the highway.

This is not my first Jeep. My other vehicles besides Jeeps have been Ford Super Duties with solid axles. I'm familiar with the difference between IFS and solid axle handling but this jeep is not right.

Why not attempt to get the steering box replaced under warranty first?

I'd like to suggest that likely all JL's have some sort of issue with "some" dead play in the steering box. If a particular JL tracks straight though, the dead play is much less noticeable (as mine is now). Also, I bet some people just deal with it (and say their steering is fine) and others are picky and complain about it.
Completely agree. Drove a buddy’s 2019 JLU who said his was fine until I pointed out it wasn’t and now he can’t get it off his mind. :angry:

I've been waiting for a newer revision. I've drove a couple with the AE box and they still had play. I would rather fix it right and be done with it over having to keep going back and forth to the dealer and hoping I get a good box.

I agree. Luckily mine tracks straight now. Only about 1/4 to 1/2 inch of dead space in the steering. To me it's bearable and I only occasionally notice it since mine tracks straight now. I am not messing with mine unless there is an updated steering box over the AE version that proves to be much better.

PSC kit is not that expensive considering how much any of us will lose on depreciation just trading the JL in for anything else.

Approx 15k on 2020 2dr rubi.
Drives so much better on the highway when the top is down. With the top up, the wind blows me into the next lane.....
Fun

I got under the Jeep and had my wife move the steering wheel back and forth through the dead zone range. Steering shaft would move but the pitman arm wasn't. Makes it pretty obvious where the slop is coming from.

Cross caster is what it is in a Jeep. If you try to introduce more into the Jeep you will be putting one or more of the control arms in a bind and it will cause more steering issues

[/QUOTEthe Jeep specs actually do specify a cross caster up to +.5. Perhaps you can explain how two arms that are non adjustable and the same length can have any cross caster? There wasn’t any cross caster in mine from the factory. The adjustable arm bushing and even the stock will easily allow for a difference of +/-.5*.

The increase in caster from +5*.0 to either +6.5 or greater is on BOTH arms and only if you have adjustable arms. Cross caster is one arm very slightly ( a HALF a degree or less) longer than the other depending on the which side of the road the crown is.

In addition the synergy Clayton Off Road LCA’s (which are in my JLU) are available with DUAL DUROMETER Bushings which do not allow for for any bind. There were all kinds of steering and handling issues in my JLU from the factory. The only steering issue thats left is the dead spot, which as I said is far more manageable now.

Test drove a 2020 JLUR yesterday, drove perfect ---whereas the 2019JLUR I own I have gotten down to now only dead spot(which sucks that JEEP can't fix this- had them put AE box) fixed the wandering with LCA and also added adjustable steering stabilizer

When the outer C is welded on there is a slight difference built in for cross caster from the factory, been like that for years.
Here is a great explanation of how to properly install adjustable arms.

Do you really believe that a 1/4 degree to half a degree of caster can be accounted for by position welding brackets? That’s better than aircraft frame assembly. Have a look at the JL frame welds. Believe what you will, I know better and this is a waste of time.

considering I am a technical trainer for a collision group with over 700 locations and I have seen 100’s of the Jl platform on measuring systems across the US and Canada yes. Also the axels are made is a jig which located the C’s in the position desired prior to welding. The JL has a factory tolerance of +/- 10MM on ANY point of the frame or unibody structure. I have personally measured 20-30 of these and have seen suspension mount points 7-10MM different from one side to the other. My personal JL is 4MM off on the front lower mounts. The factory arms are exactly the same length, because of the frames not being not being consistent that contributes to the handling issues, the factory arms are in a bind. Also FCA has 3-4 different manufacturers for the frame and they are not consistent from one to the other.
Feel free to believe what you want, I KNOW better. I do this daily and also by the way I am also a FCA certified structural tech and 200+ of our facilities are FCA certified shops.....I have probably seen more of the inconsistencies on the JL platform than anyone.

DO you know of a fix(or one coming( for this steering issue(dead spot) with you experience, fixed my wandering with adjustable LCA bringing caster over 6.0

Is there a way to tell which manufacturer makes the frame(s) that seem to yield no steering issues ?
