Well thank you kindly! I didn't even think of tb, pcv, and egr!! I appreciate it!!:smiley_thumbs_up:The big services are in 30,000 mile intervals. If you don't know for sure that any services have been performed then everything needs to be done. Plugs, oil, clean the throttle body, pcv, and egr. ATF+4 in the transfer case, power steering resivoir, and transmission( 17qts and 2 trans filers). 75w90 in front diff and 75w140 in rear diff plus a bottle of mopar friction additive if it's LSD.
