You can't see much from the photos, but someone might catch something I missed.
I need to look up that method for preload, I didn't have a tool to measure so just went off of best guess. If I did mess it up would it be a constant hum? I couldn't get the sound on video, it's such a deep noise and the vibration is coming more through the vehicle than anything. It isn't constant, I hear it more at 35-40 than I do at 55, but sometimes it's more severe, sometimes I can't get it to sound at all. That's one reason I'm hoping it's the pads, I would guess if it's a bearing it's going to be consistent.
I'll get it on the highway for a short bit and check the hubs and the rotors with an infrared thermometer, I didn't think of that. I would assume comparing to the passenger side will tell me where the friction is.
The hubs say it's in 4x2, one thing I did though is put a lot of grease in the locking mechanism. Should that have been dry? Is it possible it locks itself from the pressure? These are the Warn hubs so I didn't have those spelled out in the fsm.
The calipers are supposed to be oem remanufactured ones (from O'Reilly's). It doesnt look like the inside pad is backing off the rotor at all.
I appreciate the brainstorming ideas. I would also add that if anyone is in or around Concord I'll meet you at a brewery of your choice and pay for your consulting time in beer if need be.
