Jeep Wrangler JK (3rd Generation)

2007–2018 · JK · suv

JK Wrangler (2007-2018) is the generation that introduced the 4-door 'Unlimited' body — Wrangler sales exploded the day it launched. Two engines: the 3.8L EGH V6 (2007-2011, weak and thirsty), then the 3.6L Pentastar V6 (2012-2018, much better). Solid front Dana 30/44 axle, leaf-no, coil-yes. Sold alongside the JL from mid-2018 as the JK was wound down. Aftermarket support is the deepest of any Wrangler generation.

Watch out: Death wobble — violent front-end shimmy triggered at highway speed by a bump or expansion joint. Caused by worn track bar bushings, ball joints, steering damper, or tie-rod ends; lifted JKs are especially prone. Diagnose the front end as a system, not by replacing one part.
