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:
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.
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.
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.
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.
