Re: Looking at 2006 WK
Get the repair and service history from the dealer; leaking trans cooler lines are common as are broken front diff mounts; both costy to repair. Shocks wear out quickly, as do sway bar end links and bushings. If the diff's whine, move on as it is not worth the cost for repairs. IF you buy it, first thing to do is clean the TB and put on a catch can, or even better, replace the TB with a MM CNC ported 85 mm TB; wakes up the Hemi much more than any intake or exhaust, and improves mpg.
