I have a 98 Durango I was wondering what kind of matince I should do since it is about to hit 86000 miles on the od. I bought it when it had 84000 I just want to keep up so the warranty I have stays vallid.

 

I would change the plugs, wires, cap, rotor, all fluids (oil, tranny, transfer case, diff/diff's), T-stat, and check the belt. Also see if you can get a hold ofany maintenance records on it and you may save a few $$$. When you do the ignition components stick with Champion plugs and don't get cheapo stuff, stick with OEM or go with MSD ignition components.
