6 Cool Things to Know about the Jeep Wrangler JK

  • The name JK doesn’t have any exact meaning. When Wrangler became part of the Jeep family in 1987 as a replacement for the CJ Series, engineering codes were used as a name for the earlier-generation Wranglers, the YJ and the TJ. The JK, however, didn’t follow this sequence or trail. Under Chrysler’s engineering series code, the next-generation Wrangler that would be released for the 2007 model year was supposed to be called the TK. But because this didn’t have any “J” in its code name, the team eventually settled with calling it JK, which was purely random.
  • The earlier Jeep models were given names that followed an engineering code series YJ and TJ and initials MJ, which means Military Jeep, and CJ, which stands for Civilian Jeep. While JK appeared random and just a way for the team to insert “J” in the name, some people would like to think of JK as an initial or abbreviation for “Jeep King.”
  • The JK was the first among all the Jeep Wranglers to feature computer software control. The software can run the lights and auxiliary systems, engine, transmission, and, to some degree, even the brakes. Various vehicle functions, other than steering, were computer controlled in this Wrangler.
  • The JK, initially released for the 2007 model year, introduced a redesign for the Wrangler and came up with a four-door option, as opposed to the usual two-door design of its predecessors. The body styles of the earlier YJ and TJ were limited to a 2-door convertible and a 2-door SUV. When the JK was launched as a next-generation Wrangler, it added a 4-door convertible and 4-door SUV to the usual lineup.
  • With the release of the JK model, the Wrangler introduced new features and a lot of firsts. Power windows and remote power door locks were first seen in this model, along with the navigation system. Modified tail lamps were among the big changes. The JK was, in fact, the first generation of Wranglers to have this feature.
  • Even with other utility vehicles on the market, the JK stands out because of its uniqueness. It was even more popular than its predecessors and was way ahead of them even in terms of sales.

  • Usual Problems Encountered with a Jeep Wrangler JK

    Jeeps may not be the daintiest 4x4s that you can spot on the road, but their ruggedness has always been part of their appeal. If you’re driving a Jeep Wrangler JK, a few scratches here and there, mud and dirt, and even some bumps and grooves wouldn’t really faze you. The JK, after all, can go real smooth on the pavement but can also turn into a beast on rough roads. However, as with other Jeeps and vehicles, they’re not crafted to absolute perfection. You may also encounter problems with this Jeep. Here are some of them:

    Fuel overflow

    Jeep owners have reported fuel overflow to be a common problem with the Jeep Wrangler JK. Because of this issue, some were careful not to fill their tanks to the brim so that fuel won’t come spewing out of the vehicle. If your JK is still under a warranty, the problem can be fixed at the dealership at no extra charge. Jeep owners with a run-out warranty have resorted to replacing some parts of the fuel system to fix the overflow problem.

    Leaky top

    Another usual issue with the JK is a leaky top. This goes for both the soft and the hardtop. Some have reported leaks coming from the back and at the A-pillar; water gets into the cabin easily. The top, according to Jeep users, can be a hit or miss when it comes to leaks. This can be resolved by changing the seals or replacing the top altogether.

    Steering knock

    A knock in the steering system has been an issue with the JK. Some of the steering knocks happen every once in a while. But, those who consider this a persistent problem had to replace the column and some of the shafts to restore proper steering. Clunky steering can be caused by a displaced boot at the firewall or may be a result of insufficient amount of grease on the slip joint.

    Other problems

    Common problems with the JK also include premature ball joint failure, leaking axle seals, and dead throttle. There has also been a good number of recalls issued for this model. Problems range from incorrect spark plugs and faulty cargo lamps to prematurely activated ESP systems and torque converter shudders.
