whats a commen JK problem

[JayKay]

It depends on the jeep some have had issues with the 3.6 and some haven't, I've had my water pump replaced and my dual stage oil pump, other than that I haven't had any other issues, if you plan on running big tire do c guessets to prevent the axle c bending

Curious...what was your mileage when you had the water pump replaced? I've got 52,000 on my 2012 and noticed the water pump whistling at idle tonight after running some errands. Wondering if it'll be covered under the 100,000 mile powertrain.
