Parking Brake Repair
After diagnosing the intermittent vibe problem I took the truck in to the dealer. They replaced the parking brake pads and adjusted them way loose. It did not fix the problem so I did it myself.
The parking brakes are a light duty drum brake located inside the rotor.
The offending part is the expander cam, which is the piece that the cable hooks onto. It was completely rust welded.
I broke it apart and applied caliper grease.

I just did the repair yesterday, but the parking brake now works normally and no vibes so far. I manually worked the brake before I put the cable back on and it was easy to apply and released cleanly.
I used CRC Brake Caliper grease. Did both sides, although the left side wasn't frozen, yet. Don't forget to grease the caliper slides while you're there. The cam part is just cheap pot metal, buying a new one might actually make it worse as the old ones are starting to develop a hard surface.

They can cause a TREMENDOUS amount of vibration, enough to make you pull over and stop. A partially engaged drum brake will do that. I am reluctant to post this on the internet, but I got caught in hurricane Alex down in Hatteras, and I suspect that this might have had something to do with it. I also drive out on the beach quite a lot when I'm down there. I should add that the truck has been running great since I fixed the parking brake, I really like the beast! Averaging about 15mpg, it's a great ride.

It did great! Just put it in 4wd and take the tire pressure down to 25. I found that leaving it in 4wd High and drive worked the best. Going from Billy Mitchell south, I didn't even put my hands on the wheel, the truck just followed the tracks. Engine temp stayed low and she crossed over the tracks great when asked. Never had any fear of getting stuck, but if you do let the tires down to ~12. Plus the bed is deep enough that my girlfriend could get a full body tan without having to worry about gawkers.
