Jeep Grand Cherokee 1999 $4,999

Selec-Trac had the option of either full-time or part-time operation; both shift-on-the-fly Command-Trac and Selec-Trac were already available for the Cherokee, and they were adapted to the Grand Cherokee., , The Quadra-Coil suspension was standard and featured a solid axle multi-link coil spring design. By allowing the locating arms to positively control axle positions the handling attributes were improved. The rear suspension has 4 trailing arms with two coil springs per side. Like its XJ counterpart, the Quadra-Link front suspension was carried over., An available "Up Country" package was offered. The suspension package included heavier duty German made gas charged shocks installed upside down, taller coil springs and longer bump stops. Ground clearance was increased by one inch., , Awards, 1999 (with its acclaimed 2nd generation model), , The redesigned WJ 1999 Grand Cherokee shared just 127 parts with its predecessor (mostly fasteners). The spare tire was relocated from the side of the cargo compartment to under the floor. The two heavy pushrod V8 engines were replaced by Chrysler's then-new PowerTech. New V8 engine produced less torque than the old pushrods, but was lighter, offered better fuel economy, and provided similar on road performance figures (the 23-gallon fuel tank was replaced with one of a 20.5-gallon capacity). The Inline 6 engine was also updated in 1999. A redesign of the intake manifold added 10 horsepower (7.5 kW). While other Jeep vehicles used the Mopar 5 x 4.5 bolt circle, this was the first Jeep following the 1987 Chrysler buyout to receive a wider bolt pattern: – 5 x 5., A notable feature available in this generation was the automatic four wheel drive option called Quadra-Drive, which employed the New Venture Gear NV247 transfer case. This two-speed chain-driven transfer case uses a gerotor, a clutch pack coupled to a hydraulic pump, to transfer torque between the front and rear axles. The transfer case contains three modes, 4-All Time, Neutral, and 4-Lo. In 4-All Time, 100% of torque is sent to the rear axle in normal conditions. If the rear axle starts spinning at a higher rate than the front axle, hydraulic pressure builds up in the gerotor and causes the clutch pack to progressively transfer torque to the front axle until both axles return to the same speed. Neutral mode is intended for towing the vehicle. In 4-Lo, the front and rear axles are locked together through a 2.72 reduction gear ratio. The NV247 transfer case is mated to front and rear axles containing Jeep's Vari-Lok differentials. Vari-Lok differentials also use a gerotor to transfer torque between the wheels on either side of the axle. The major advantage of Quadra-Drive was that the combined transfer case and progressive locking differentials in each axle could automatically control traction between all four wheels. However, only the center differential could be permanently locked, and only in 4Lo. The Quadra-Trac II system included the NV247 transfer case with the standard open front and rear differentials., The 45RFE and 545RFE automatic transmission in the WJ was notable. It included three planetary gear sets rather than the two normally used in a four-speed automatic. This gave it six theoretical speeds, and it would have been the first six-speed transmission ever produced in volume, but it was programmed to only use five of these ratios. Four were used for upshifts, with a different second gear for downshifts. Although five of the six ratios were used, Chrysler decided to call it a "4-speed automatic". In 2001, the programming was changed to make use of all six ratios. Rather than have six forward gears, the transmission was programmed to act as a five-speed with the alternate second gear for downshifts. The RPM at 70 miles per hour (110 km/h) on a 545RFE is 2000 rpm, 200 rpm less than the 45RFE programming. 1999 and 2000 model year WJ owners can have their 45RFE transmission's programming flashed to enable the extra gear as
