Jeep Grand Cherokee WJ (2nd Generation)

1999–2004 · WJ · suv

The WJ (1999-2004) was a complete redesign of the ZJ that kept the solid-axle, unibody recipe but added the all-new 4.7L PowerTech V8 alongside the carryover 4.0L inline-six. Quadra-Drive with the Vari-Lok progressive locking differentials made the high-trim trucks genuinely capable off-road. Interiors moved upmarket and the WJ is generally considered the most carefully engineered Grand Cherokee of the early era. Sold through 2004 before the WK replaced it.

Watch out: The 4.7L V8 is known for timing chain tensioner and guide wear; owners often describe the resulting noise as a 'screaming chicken' or rattle on cold start. Sludge from missed oil changes accelerates the failure. The 42RE four-speed automatic behind the 4.0L is also known to develop overdrive and torque-converter issues if fluid changes are neglected.
