There are scores of Jeep JK Wrangler forums, and why not? Chrysler/Jeep just announced the build of the one-millionth JK Wrangler, and that's something to boast about!


I fielded the Camp Jeep Mopar Tent workshop questions for over a decade, and when the TJ transitioned to the new JK Wrangler platform, it was immediately clear that the new Wrangler had a more robust and stiffer frame. The suspension tuning level, NVH advancements and sound deadening were unfounded in earlier Jeep utility models—yet the iconic ladder frame and beam axles were still in place...


This vehicle went on to steal the SUV market with its popular Unlimited four-door option. The Rubicon Edition enjoys an industry-wide reputation. When I tested the 2012 model with the Pentastar 3.6L V-6 replacement for the 3.8L V-6, the new A580 five-speed automatic transmission got my attention. I tested and personally picked the 2012 Jeep JK Wrangler Unlimited Rubicon 4x4 as the magazine's "Best SUV of the Year!"


Note: If you're curious about the JK Wrangler coverage and perspective at the magazine, type 'JK Wrangler' into the keyword list at the magazine's search box.


When the economic debacle hit, the days of the Suburban and Excursion were already done. The Jeep JK Wrangler quickly filled a consumer void, and the idea of having a good time, not just getting from point 'A' to point 'B', captured the imagination of new buyers.


Our fresh forums hold the promise of reaching 4x4 enthusiasts at a new level. In the case of JK Wrangler owners, this means everyone from the Rubicon Trail runners who really do need 37" diameter tires to suburban families trying to maintain a vehicle and feed a family at the same time.


Wondering just what kind of information you can find here?  Join and post your topics!  Expect objective, "real" replies that won't have you asking your bank for an extended line of credit to buy "must have" modifications and upgrades. Sure, there's a place for upgrades, and I'd be pleased to point out when and why. 


Expect candid answers to questions like which model Jeep JK Wrangler to buy in the first place or what you really need to reach your planned destinations.


There's no agenda at this forum.  The goal is simply safe, fun use of your 4x4 JK Wrangler.  Whether maximizing fuel economy is your aim, restoring or replacing powertrain components, or prepping for the ultimate destination four-wheeling, get your facts straight—here!


We welcome your forum membership and participation...

I have a 2013 Jeep JK Wrangler Rubicon Unlimited. I off-road it quite a bit. It is lifted 4" all suspension including shock mounting, sway bars etc have been replaced/ re-worked, it is running on 37" tires, new driveshaft etc. I am running into the well documented issue of the water pump beginning to squeak and squeal. I am interested in swapping the stock pump out for a digital thermally controlled electric 115 LPM water pump from Davies Craig.


Two questions: is this a reasonable alternative to replacing the stock pump for a daily driven off road vehicle, and how do I go about re-routing the serpentine belt?

Welcome to the forums, nbruno!  I am at Moab EJS (not at my shop/studio) and would like to explore the Davies Craig water pump further.  I took a quick look at the corporate site, and the electric water pump is interesting.  I would like to research the longevity (duty cycle) of the electric motor when running continuously or thermally activated.  It would run continuously in a warmed-up engine in all likelihood, and engine coolant heat is substantial. 


Also, re-routing the belt to stop turning a squeaky mechanical pump is suspect.  The parked impeller could create a blockage of flow.  I would like to know the problem with the OEM water pump.  Is anyone making an OE mechanical water pump that does not create trouble?  On that note, is the problem squeaks or actual bearing and eventual seal failure?  Squeaking can sometimes be strictly belt and pulley related.


Please share what you know.  I'm glad to research further so we can determine a sensible remedy...
