So, was returning from GER Sunday... where I lost (most of the) brakes on it upon reaching Hwy.19 (compounded by losing trailer brakes on Thursday heading up) 
Hit O'Reilly's in Oak Hill to discover pass. rear caliper puking (Sherlocking: it appears the lower caliper pin seized, smoked inner pad, remnants of pad rotated up, allowed pistons to contact smoked rotor until there was clearance for them to pop-out, and resulting in rapid fluid loss), but they had everything (calipers/brackets, pads), so only took a couple of hours to get back to stopping. (will revisit BOTH rotors next month)
Anyway, made the rest of the trip without issue until I got to the Meadows of Dan (15 miles out), when something in the front-end started making a weird chirp/thunk...
Initially thought it was something 6.ohL engine related, but all vitals were good, and nothing amiss under hood.
- Windows down @ 20 mph sounded like passenger side
- Didn't appear to be speed related
- Didn't appear to be suspension related (bumps, etc.)
- Didn't appear to be alignment/steering position related
- Confirmed both hubs unlocked (M-M, not factory)
- Temp checked both unit bearings (both near 100*)
- Temp checked both calipers/rotors (both near 100*) given the previous issue
- Visually checked the shafts/joints to make sure they weren't flopping/slopping (no shiny marks)
- No visible issues w/ suspension components, including newer swaybar links/urethane bushings
Similar sound to trailer suspension popping when turning hard, or a swaybar pop, but happened when going straight.
Was REALLY suspecting a unit bearing seizing, but temps (backsides) discounted that
Began to feel slight feedback thru steering wheel when it happened, but that stopped about a mile from the house and didn't reappear, even when 4LOW to climb hill to shop
