Just an update here. Driveline clunk seems to be fixed. There is a zerk fitting just behind the first U-joint on the axle. Pump grease into it until you see it oozing out of the slip joint on the axle. It took nearly a whole tube of grease on mine so it must have been really dry.
The new fuel filter seems to have resolved my hard starting issue. I also discovered my water indicator was disconnected from the bottom of the filter. Plugged that back in. BTW, if you have a really old fuel filter prepare for it to be really stuck on there. There's not enough room to get a tool on the filter so I had to use 2 hands and a very ackward stance to remove it. My back has been killing me for the last few days after removing it.
Oil change was super easy, no jacks or ramps required. I put in 4.3 liters of Rotella T6.
I still have the random dash lights, I was hoping to have that resolved before my big road trip up the coast this weekend, but I'm not too worried about it.
I had an alarm installed with keyless entry, so no more worries about broken keys. I'm getting a new exhaust system tomorrow (old one was falling apart). After my trip I will be installing a custom trailer hitch and then it's on to the audio system. I already have a 2-din Pioneer installed with BT, but the factory speakers need to be replaced with good quality ones.
