'99 - Hub hum - lube? (first post!)
Hi, - first post - thanks in advance for your help!
I have a '99. I did the "fix" to bypass the pvh system yesterday. (the one that leaves a "push-button" system) - seems to work great.
My question is - with what, where, & how, do you lube in these systems? I have a "hum" that varies with speed, that I'd bet is coming from the 4wd... The visable gears appear relatively dry and clean... Should they be?
I haven't had this truck long, so I can't be sure when noise started. It does have new tires but I don't think that's it.
Recently, a guy was trying to "fix" the 4wd and one of the things he did was to swap the front hubs from side to side... Could he have done something there?....
