I completed the replacement of the compressor, the rear shocks and the rear springs. I connected the air shocks to the compressor, but I did not connect the electrical connectors to the shocks, as I am awaiting receipt of a salvage set of electrical connectors. All went relatively smoothly, and I did not get the opportunity to invent many new swear words.
When I started the truck, though, it threw a bunch of DTC codes, with the ABS light being the most unexpected code. I diagnosed it with my Tech 2, and I narrowed it down to the rear driver's side wheel. So, I jacked up the truck and pulled off the wheel, and I found that the ABS connector on the frame had become disconnected somehow from the wire running to the wheel hub. Once I reconnected it, all the trouble codes went away.
I then used my Tech 2 to re-set the automatic level control trim on the truck.
Next week, the front suspension components will be installed.
So far, so good.
