A note on the part numbers. The FCA part number is 12345678RR. The RR is typically a revision. Example AA then AB.

The second group is the manufacturer number. 61177 in this example.

The final numbers will change. This is a date code. Typically a Julian date. DDDY. Meaning the day of the year is the DDD, so Jan 1 is 001X and the 100th day of the year is 100X. The year, 2017 would use the end number, so 2017 is 7.

Hope this helps. Old thread but for clarification on future readers.

What i am researching now is that all Rubicons are twitchy on the road and do not have good steering manners.
The Mopar 2" lift includes new longer by .25" lower front control arms. Thinking this may help a lot of us.

Yes the Mopar 2 lift ones helped me. 68322798AA about $30 each. That and the toe in set at 1/16 = no more wander. If I could get rid of the "play" in the steering wheel that would be great. At least it drives down the freeway at speed with no hands on the wheel.
All control arm are the same even the JT's.

This is good info thanks Kevin.
Re: your steering play, i have heard steering box upgrade, steering stabilizer(which i don't believe in my history of having jeeps from 1993) and the SW change from the dealer from -8 to 0.

Update from my own personal issue. Get the steering box tightened by 1/8". ZERO play now! I still have the wandering issue though lol.
