Bought a used 2003 Durango SLT 5.9 RWD Feb 2017. Never shop for a vehicle when you are A) Desperate B) It's Raining C) A and B.
Bought it for around $1200. ABS light was dinging but I didn't care. Should have but see above. 3 tires + the spare were all different sizes and the check engine light was off so my gullible self went in.
Did a test drive. It had potential, nothing majorly wrong that I could "see" and everything appeared to be Okayish. I was wrong. Mpg from the time I bought it till I started fixing it was 7.6 on the highway. Now in the city it's 9-10 mpg and 15mpg highway. Lots of room for improvement there but was not the deciding factor when buying it. I didn't expect this beast to get great fuel economy just wanted to throw it out there.
First thing I did was take it to get Smogged and then to the tire shop. Put Cooper Discover 255/70/R16's on it and stopped by and purchased AAA roadside assistance as I had a used truck.

Also called a mobile locksmith to make me another key and two remotes. The key fob I was given didn't work and I only had one working key. That wasn't going to cut it for me.
Mobile locksmith got it done for $125.
Went to change the brakes and found out that when the tire shop put on the tires they had stripped 15 lugs. Seriously was pissed. There is no excuse. They paid for it all but it pissed me off.
When I finally got everything taken care of with that I started inspecting brakes and suspension.
I was greeted with this
Upper control arm had seen better days. I made the mistake of trying to go to Autozone for the part. It did not even remotely match. Went to Kragen (O'reilly... I prefer Kragen) and got a control arm and changed it.
After this I had a slight overheating problem and the sound of gurgling fluid. Overflow tank did not have a cap so I replaced this first and it did not change the problem.
Ended up taking the truck to a shop for an inspection and to fix the overheating as I didn't have the time and wasn't really familiar with the truck. I did buy a repair manual jack and jackstands (my 1 ton jack and jackstands wasn't going to really cut it) at this point but that's as far as I had gotten.
Long story short on the shop. I got hosed. $300 for them to diagnose the overheating.... went from Possible head gasket being blown, we argued and magically that wasn't it, then the radiator was the problem ($800 quote for this) and I again argued. Went down there they finally stated the problem was the thermostat and one of the heater hoses (the really long one) needed to be replaced for $500. We again argued. They ended up replacing the t-stat, t-stat housing, and with the diagnostics it came out to just around $300. I just wanted my truck back and figured $300 at the time wasn't that much. I really should have never let anyone else touch my truck. I hate shops and I don't trust anyone.
Kept meaning to get things done on the truck but you know how life is. I had a small leak somewhere in the truck. It didn't leak that much and everything seemed alright. Lot of stuff going on until eventually I drove the truck and it overheated.
Guess I'm going to have to fix it now
Separated here near the filler and sprayed the entire contents of the system everywhere.
Extremely happy I had AAA
Went to the local dealership for price quotes and a few questions to be asked and answered. Gave them a 5 star review and they gave me a hat. Really should be called MoParts but I'll get to that later.
At this point my wife and I sat down and had a discussion about the truck (I use truck and suv interchangeably ) and we decided that if the compression test came back good we'd chase the rabbit down the hole. That regardless of what needed to be done we'd fix the truck as it had good bones (no-rust) because we liked the room that it affords us (3 children) and it's nice to have. If the motor needed to be yanked we'd let it sit on jacks and go from there.
Compression test came back aces. With less than 8 percent variance on all cylinders.
Majority of parts came from Rock Auto, Followed by Kragen (O'reilly), and Mopar.
Figured if I'm going down the rabbit hole. We're going to be replacing everything I can think of that would need to be changed. Rad hose blew so we're going radiator hoses, heater hoses (since shop told me it needed to be done), spark plugs, spark plug wires, distributor cap and rotor, water pump, timing chain (since it's right there) and all in between.
Here is the culprit to 90% of my problems. Power steering Pulley had come into contact at some point with the overflow tank. This was the patch job. (not me)
How the shop missed the above is beyond me. Perhaps they never pulled it. The claim they did a pressure test and the overflow tank was never mentioned. I missed it as well but I wasn't exactly looking either as I took it to the shop for that. I've learned my lesson. What I didn't know at the time. and I had to rip it apart later (I glanced over it) was the thermostat housing was slightly pressed upward because the shop had heli-coiled (or previous owner) the intake manifold and jacked it all up. I ended up having to use a tap to get the intake manifold the exact way I wanted it. Was a lot of searching on this forum for all of this. This truck would be the biggest mechanical undertaking I've ever done.
Had to remove the water pump in order to get the fan clutch off. It was frozen into place. Also took off the alternator bracket (not pictured)
Trick I learned getting the harmonic balancer off with a three prong puller. Seriously we tried all night long to get the damn thing off using a three jaw puller and it just wasn't happening. Wish I would have found it sooner. Seriously. Thank you Youtube.

Timing chain cover. Wow.
Old timing Chain set up. Replaced all of this
New Water Gates water pump and water inlet tube $32 from Rockauto.(i replaced this damn tube like 10 times from mistakes and leaks). Dayco Harmonic Balancer $62 from Rock
Semi reassembled looking at fitment issues. I also replaced the bypass hose.

Assuming these bad boys weren't changed anytime recently.
Riding Dirty. New plugs/wires, distributor cap/rotor, valve cover gaskets, ignition coil were all done
