The WK Soldiers On
Our long-term Grand Cherokee Overland continues to serve us well. Whether it's going to get groceries at the supermarket, towing loads, or heading into the backcountry on an exploring trip, the Grand Cherokee delivers.
In the last installment, we mentioned a weird pulsing that was happening during acceleration. As we had no Jeep dealers here in southern Utah at the time, Chrysler picked up their vehicle and took it away for a re-flash of the computer. The WK was gone for a month. We've never had a test vehicle we missed more. It was like welcoming an old friend when the Cherokee was returned. The re-flash worked, too. The pulsing is gone.
The 5.7L Hemi has plenty of power and the Quadra-Drive II four-wheel-drive system performs flawlessly, as we've mentioned in every installment. Why Jeep doesn't use the Quadra-Drive II with its automatic locking front and rear differentials in more Jeep vehicles is beyond us. It is the best four-wheel-drive system available today on the planet.
The rack-and-pinion steering has given us no problems and the independent front suspension is, well, an independent front suspension. The coil rates are fine for this vehicle, but the shock valving is too light when off-road. If this was our vehicle (and we wish it was), we'd install a 4-inch suspension system for better performance and off-road clearance.
The WK is about to be replaced by the new 2011 Grand Cherokee that's changed in almost every way. It will have to be a great vehicle to be better than our 2009 Grand Cherokee Overland.
