Things to note when changing the timing chain on a 2wd model: to drop the oil pan:
You must remove one of the tie rods to give enough clearance for the pan to drop under the pickup.
I'm over 20,000 miles and counting on my timing chain replacement. It started making significant noise around 160-165,000 miles, I parked it at 172,000 until I could fix it. One of the mounting holes on the plastic guides was completely broken and in the oil pan, the other guide had a long crack in it but was mostly all there. I got lucky. I did not replace the head gasket, just pulled the oil pan.
