Help me determine if my wheel bearing/hub assembly is bad...
Well.. My 99 4x4 Ranger has 150k miles on it. I have had it for a year, so I am not sure if the wheel bearings have been replaced prior to me owning it. I have been double lifted on 35's for, about 2k miles. I have been reading up about wheel bearings.. I noticed on my pickup, at certain speeds, noticeable most at around 20mph or 30mph on decel, or at crusising speed.. kind of a humming type sound. It doesn't sqeal, or grind.. it's more of a humming type sound, maybe could be considered growling as some people put it. I jacked the truck up, and checked for play in the wheel.. there really is none at all, but i know that doesn't exactly mean the wheel bearings are good. I freely spun the wheel while it was jacked up.. and i don't really hear any unusual noise.. it just sounds like any vehicle does... maybe just alittle break pad friction against the rotor sound. I am having a hard time determining if it's just the howl road noise i'm hearing from the KM2's. Also, when i come onto a freshly paved road, black topped street, the humming is quite a bit more noticable. It doesn't seem to do any different while turning or anything.
Anyway..
I figure i'll replace them here at some point... and i know it will be hard to even diagnose from what i described.. but if anybody could give me their input or thoughts i'd appreciate it. And also, When I did my superlift I had to pull the knuckles so I pretty much know how the hub assembly goes in the spindle.. CAN i leave my knuckle attached while replacing the hub assembly?
Thanks alot guys!

I'll have to do that. There is a video on here somewhere from Shane B. It's a video of his pickup when the wheel bearings went bad.. and it clearly had a **** ton of play in them, and the camber was way out. I didn't get a chance to pull the brakes like you guys suggested, but when i grabbed the wheel at 6 and 12 it was pretty damn tight.

Yes, I have the Ingalls Camber Kit, and had it aligned at a shop after lifting it. My camber looks fine, I was refering to a video Shane had posted here when his wheel bearings went, and it was apparant that it was sitting way negative on the top side of the wheels.. and in his video it had a good amount of play in all directions with the truck jacked up. The only thing that makes me think i might have bad wheel bearings is the odd humming sound i get at lower speeds. And, No, i have no replaced my front drive line yet.
