Nickname: The Barge
Mileage: 260000
Engine: 4.6 SOHC, ported/polished plenum, 70mm BBK TB, K&N FIPK,
Drivetrain: Stock 4r70w, 2.73 open, Heinous rear control arms, Raybestos HD front LCA, Moog Problem Solver UCA, Gas-A-Just shocks, P71 rear coils.

TR360, and 3L27 install coming soon. (I have all the parts)
Notes: I drive this car as a daily. I enjoy this car very much, and frequently take road trips with it. I bought the car in Zumbrota MN, with 80k on it in 2010. Soon after, the car has never seen salt again as it has resided west most of its life. I have done all maintenance myself, and have put 176000 miles on it since purchase. I have turned nearly every bolt on this car, and has kept me occupied in my down time, in a good way.

I enjoy working on this car, even when I have problems. It's a fun driver, and super easy to work on compared to any modern truck/car I know of. There's so much room everywhere to work!

84,223mi Bought September 2010.

85k-260k- Oil changed every 5k miles. Used Mobil1 until 95k, switched to Valvoline 5-20 fully synthetic.

120k Replaced EATC unit as any setting resulted in blowing out the defroster. Opted for an eBay rebuilt unit that has upgraded O-rings, still works great.

Shocks replaced at 140k with KYB gas-a-justs.

Rear P71 springs installed at 220k, old ones were getting weak, rides firm, and level now.

Badly needed trans flush at 200k, magnet showed barely any wear, and filter wasn't obstructed. Found factory dip stick plug in bottom of pan. 60k later, still shifts great!

spark plugs changed every 50k.

Front/ Rear brakes replaced at 85k, and 170k just front. Always replaced with ceramic pads. Still original rotors.

Watts link, and rear control arms replaced at 180k, with Heinous control arms, and Dorman.... watts link.

LCM replaced at 220k, running lights quit working, only headlights worked.

UCA, LCA, inner-outter tie rods replaced at 200k. Right front lower ball-joint was going out, so I opted to replace everything at once.

Intake manifold replaced at 210k, aluminum crossover leaking where it mated to the surface of the plastic intake.

Timing guides replaced at 250k, was just checking them since they were replaced by the dealer with the X... on the valve covers at 80k, and found the driver side guide was broken, and guides were almost to metal, very very close.

Tires replaced at 120k with Michelin Hydro Edge 235/60/16

02/29/16Maintenance258000New tires
Right front tires had broken belt, and right rear started leaking where the sidewall is molded to the tread. Tires had 129k miles, and the tread had about 20% life left.

Front: 235/60/16 Defender series
Rear: 255/50/16 BFG Sport Comp
650.00
02/20/16Maintenance254000Charcoal solenoid
Removed black box to get at charcoal solenoid. I heard it's common to have buildup, and after many pictures, I was sold. I took it all apart, and had to cut a bolt holding the black box on.

Results: I didn't have a lot of soot in there as some had with much less miles, but it was still a bit dirty, so I cleaned with warm soapy water.
