    Continuos whine. (Not me, the truck.) Lol!

    Hi all

    Just wondering if all your trucks whine like mine. Its not very loud, kicks in at about 40kph, and changes slightly in pitch but not volume level as speed increases. The tone changes slightly in quality if the throttle is backed right off (almost as if whatever is being strained against is straining in the opposite direction because of going from momentum to impetus ).
    If I had to give it a location, I would put it in the transfer case, or a wheel bearing. I have done the VC test and passed. High and Low range work a treat, auto is fine, motor is smooth, diff oil is clean, uj's and drive shafts are firm, cv's are not crunchy.
    My old man had a Toyota cruiser way back when, and it sounded the same. It wasn't broken, it was just the way it sounded. Also my old HR holden had a wheel bearing go, and it sounded similar.
    Like I said its not that loud, and it could even be tyre noise, but I don't think so. It has a gentle grinding quality about it. It could also be perfectly normal. Its almost soothing, but if somethings on the way out it would be good to know.
    I have done a good search, and am not being lazy, but 4 hours searching is about my limit.

    Any help would be much appreciated.
    Cheers

    P38 playlist in the making?

    As John Denver would say "And whine-ding down the road"
    I feel a pretty good songlist building here.
    Keep em coming.

    My P38 has what I would describe as a whining sound... guess it all depends on the ear of the hearer! Anyway finally determined that it seemed to be coming from the transfer case but could be reduced by "floating" the throttle on a flat portion of road at say 60 kmh so there was minimal stress on the driveline...

    I'll get friendly fire at this point but having read good reports on Rangerovers.net about Mobil Agrifluid 424 ...now superseded by Mobilfluid424...I drained the T/F case and refilled with this stuff. The whine reduced virtually straight away from a "what's that noise?" level to a noise you could detect if you listened intently... 5yrs/40+ thousand km later...still good. And a hell of a lot quieter than the transmission whine inside the BIL's petrol V6 Prado of same vintage (1999)

    Good on ya Hoges

    I read another thread about the Agrifluid, but they did not have 40,000 k's travel to back it up. I think this definately warrants a bit more research and some consideration.
    I'll let you know how it goes.

    Cheers

    I notice if my tyre pressures are a bit low ill hear it a bit more - could it be the humm of a slightly deflated tyre?
