Which way do I go?

Your post got me looking for a Rubicon. Surprisingly I found three manual transmission two doors for reasonable money relatively nearby. The only thing is, they were all JK’s not TJ’s. I don’t yet know how I should process that.

We all know how you should process that...

:)

But seriously, nothing wrong with a 2-door JK if it meets your needs.

All TJ's are 2-door. And yes, looking for a Rubi with a stick would be more challenging.

But if you can find one, you are ahead of the game. There are 3 differences between a TJ and a TJR:

1) Dana 44's front and rear - compared to a dana 30 up from and either a 44 or a 35 in the rear. LJ's (TJU's) all had 44's in the rear.
2) 4:1 transfer case - compared to a 2.72:1 transfer case.
3) Air lockers front and rear.

Number 3 is the game changer. A locked TJ with greatly outperform a standard TJ or LJ. If you pick up a standard TJ, locking the front and rear will be the best bang for the buck - even compared to adding larger tires. A locked stock TJ will generally outperform a non-locked TJ on any size tire.

Also, if you pick up a TJ with a 35 rear, you will want to upgrade the rear before locking it, or it will not survive any serious wheeling. Either upgrading to a 44, or doing a super 35. Both of which will cost money, and when combined with the cost of the lockers decreases the cost difference between the Rubi and non-Rubi.

You read my mind! My next research topic was the axle difference with the Rubicon. Thank you!

I’ve noticed JKs entering nearly the same price range as TJs lately. Nearly everyone here will prefer the TJ for obvious reasons.
A high mileage TJ is worth more than a high mileage JK. While the 4.0 isn’t a powerhouse it’s arguably the best motor jeep has ever produced. The early model JK I think 07-11 had the crappy 3.8 and the 12-18? Had the better 3.6 but I think some of the 12s had problems.

Rust is the biggest and most common issue while looking for jeeps. Don’t be afraid of posting jeeps you are looking at for opinions, the forum loves spending other people’s money lol.
 
Raymond, please enlighten me when you have time. I am a neophyte so the obvious reasons in favor of the TJ are not obvious to a rookie. I’m right there with you when it comes to the inline six. Very manageable low and mid range torque and I’m all in on that. What are the other differences? Please pardon my rookieship. I’m just trying to educate myself.

I see how the Rubicon is superior for the axles alone. My guess is that upgrading axles could be a $10K job, or maybe more.

The only value to the Rubicon is the 4:1 transfer case and the ability to run 5.38 gears from the front Dana 44 in cases where that is advantageous.

After that, the factory lockers are ticking time bombs that cannot be repaired.

Any other TJ with an automatic transmission can meet and exceed a Rubicon for well under $10k.

Good point on the stock lockers, Josh. Having never lived it, I always forget.
 
Okay, once I opened up my search to nationwide, I quickly came up with 8 TJ Rubicon candidates. Three of them are in pretty salty country, but the others are candidates to be culled.

JJVW seems to be bringing up more information to consider. If the Rubicon has such achillesheels, then maybe it puts me back to sport and adding the $10K worth of axles.

Lot’s of folks run the Rubi lockers for a long time - especially on stock sized tires. But JJ is right, if they do fail you are replacing them as repair parts are not available. The limited slip also apparently causes issues off road if you don’t keep them locked.

Tradeoff in every decision.

Are Rubi’s commanding $10 grand over comparable non-Rubi’s?

What does $10k worth of axles get you?

I think that it takes $10K or more to replace the axles? Is axle replacement the cure when lockers can’t be repaired?no longer be repaired?

The answer to your price difference appears to be, no. When the locker can no longer be repaired, what is the cure? A new axle?

I have a Rubicon going on 10 years that I bought stock. I still have the factory axle housings. Everything inside the axles has been replaced. 😉

Take it easy on me, I am an ignorant, rank, rookie about locker axles. Can the lockers be replaced without replacing the axle? Is it just a unit that goes on the axle?

The factory lockers can be replaced with all kinds of other carriers.
