I'm starting this thread to chronicle my timing chain replacement. I had a "ping ping ping" sound when the truck was running and it was coming from under the cover, so replacement is necessary sooner rather than later to avoid catastrophic damage. This Sport has 218K miles on it!

AutoZone has a free repair guide HERE (free registration required) that has all of the steps and diagrams necessary to complete this. I am putting my own steps and information in as I go through this to help guide others. Hopefully this all turns out OK (fingers crossed). I will edit this post as I continue.
Parts Required:
Tools Required:
[list type=decimal]
[*]Disconnect the negative battery cable
[*]Chock the wheels well so the vehicle won't move
[*]Remove the accessory belt (14mm on the tensioner pulley, clockwise)
[*]Remove idler pulley (14mm nut on the stud coming out of the front of the block)
Here is what the idler pulley looks like (note it has a nut, not a bolt):
[*]Remove accessory belt tensioner pulley (14mm bolt into tensioner assembly)
Here is what it looks like (sitting next to the tensioner assembly):
[*]Remove tensioner assembly (2x12mm - see above photo)
[*]Remove water pump pulley (4x10mm). I inserted a properly-sized allen wrench through 1 of the 2 holes in the pulley to block it against the water pump housing, enabling you to remove the 4 bolts.
Here is what it looks like, removed:
[*]Drain the coolant (put a bucket below the drain cock on the bottom of the radiator and open the drain cock)
[*]Loosen the A/C line on the top of the radiator (if you have A/C) to help facilitate removing the fan (2x10mm on the clamps holding the line in place)
[*]Carefully remove the fan shroud (4x10mm on the corners) by bending it around the fan
[*]Remove the fan belt tensioner arm assembly, fan belt & fan (2x14mm)
Here is what it looks like, removed (from the back side):
[*]Carefully disconnect the 4 coil pack electrical connectors
[*]Remove the 4 coil packs (8mm bolts hold them to the valve cover)
Here is what it should look like with them removed:
[*]I have the 5-speed, so I put the car in 5th with the parking brake on to be able to remove the crank bolt
At this point, it should look close to this:
[*]Remove the crank bolt (19MM) with a breaker bar and the car in 5th/parking brake on.
[*]Remove the crank pulley (mine came right off pretty easily)
Here is what it looks like, removed:
[*]Remove the two bolts on the little coolant hard line mounting plate (2x12mm) and swivel it aside out of the way
[*]Remove the PCV line (rear) and breather hose (forward) on the valve cover
[*]Remove the shroud (2x10mm) that covers the throttle cable assembly
[*]Remove the valve cover nuts (6x10mm)
[*]Remove the lower radiator hose and if you're doing the thermostat, the thermostat housing (3x12mm)
Note: I also ended up removing the upper hose just to make elbow room (2 clamps)
[*]Remove the A/C compressor (if applicable) and swivel it out of the way (3x12mm - one on top, two below)
[*]Remove the A/C compressor bracket (4x14mm)
[*]Remove the valve cover and cover everything up with some rags to help keep as much dirt out as possible.
[*]Remove the timing chain cover (15x10mm bolts around the sides, two underneath going through the oil pan, and one nut below the idler pulley stud)

Parts Required:
- I HIGHLY suggest you get a Japanese-made timing chain kit. I went with a FULL OSK kit (part number S601K) which includes new gears, gaskets and all.
- It is also a good idea if you haven't recently done it to get a new water pump and thermostat!
- I also suggest going with a new, full, valve cover gasket set (including the spark plug tube gaskets) since you'll be pulling the valve cover anyway.
Tools Required:
- 8mm, 10mm, 12mm, 14mm, 19mm sockets
- 10mm, 12mm wrenches
- Various breaker bars, cheater bars/pipes, socket extensions and the like
