the 2002 4.7 only had 8 plugs, thats a certainty, it was later on (2008 or later i believe) that they added the extra bank to the engine.

 

Which is why I would find another "mechanic" if he's telling her there are 16....

 

agreed!

 

I believe your engine has 8 spark plugs, so I would change the plugs and wires, oil & filter. I would have the belt checked and possibly change that as well as the hoses. At 68,000 I would also have the transmission filter and fluid changed. Have the bushings and ball joints greased. Make sure it is aligned and your wheels are balanced. Oh yeah, and change the air filter if it needs it.

That's where I would start.

 

The 4.7 has coil packs, no wires. Unless they were changed, the ball joints should be the riveted non-greasable kind...at least my 03' was.

Quincy, do you know the history of when things were last done? If the truck is running good, the situation is not dire and you can take your time to find a mechanic that won't rob you blind. Check the oil and top it off, as well as the coolant and transmission fluid. Those three are the most important things you can do for your truck.

 

First of all, welcome to the forums. The DIY Sticky section will become one of your best friends....here is the link to the FSM from that section: http://www.mediafire.com/file/2cg2hg...ice+Manual.PDF Great place to start. To confirm, your 2002 4.7L engine should have only 8 spark plugs with individual ignition coil packs mounted to the spark plugs. Dedgevity is correct, the ball joints are usually not greasable and are riveted in place unless they have been swapped out (think there was a TSB recall on it but cannot confirm...caffeine has not kicked in as of yet ) . Again as others have stated...run, don't walk away from the $1350 mechanic and the one claiming it has 16 spark plugs...lots of knowledge running amok on these boards...you'll find some great advice here. good luck with your Durango and let us know how it goes for you

 

dont just go changing stuff, check your owners manual for service due, its most likely as simple as spark plugs and air filter at that mileage, dont waste money changing the fluids before recommendation unless you are having a problem, its just costing you money that you dont need to spend. i believe transmission fluid is 100k on that truck.

 

If I were you I would get printed out quotes from a couple places and just show us what is on them exactly.
