2002 TJ : 2021 JLURD
So just brought the new Rubicon Diesel home the other day. I was relieved to hear that the steering box fix was included on the new 2021's especially since we had driven a few and noticed the loose steering. What we are noticing is at slow speed, below 40, the steering almost seems over sensitive. Small corrections create need for another correction. If the steering wheel is completely let go, it tracks straight if road is flat and straight which is a good sign. At highway speeds it seems to do much better and is actually very easy to drive. Wondering if anyone else has noticed this or perhaps something we need to get checked out.

Perhaps it's just a 'jeep thing' but I've owned multiple jeeps and still have a 2002 TJ on 35's with a 4.5 inch lift and 1.25 body lift. At slow speeds it's easy to drive, only gets squirrelly above 60 but it's still not too bad.

Not sure of the exact changes between the 2020 diesel steering box vs 2021 diesel box. What I can tell you is when we brought our 2020 diesel rubicon home it was very squirrely. Checked tire pressure, over 40#. Lowered to 35, still a bit sketch at slow and fast speeds. Logged a few hundred miles and the sensitive, sketchy steering faded away. I can’t really explain it, but it did. Drives great now. Give it some time, it may need to break in some, whatever “it” is.

I ran my 33" ridge grapplers at 28psi. Chalk test the tires and see where they need to be.

Thanks!!!! So the tires were at 42psi. Took down to the recommended 37 and all the difference in the world. Duh, now I feel silly not having even checked the tire pressure from the dealer or factory, it was at dealer less than 24 hours so not sure if they even check tire pressure.

For some reason 40-45 psi is the normal pressure for vehicle delivery to the customer. Mine were at 41 when I got mine.

42 from the dealer. My steering has felt squirrely since taking delivery last week, so as you all recommended, took the pressure down to the recommended 37psi. Hopefully that'll help.
