  • Whining noise in drivetrain

    G'day! I stuck this in the Gen 2 section but thought I'd put it here as well. Hope I'm not breaking any rules
    I have a '94 NJ 3litre auto and there is a whining bearingy type noise between 95km/h and 105km/h. The noise stops under decelaration or acceleration. Any clues?

    Also at idle maybe at the lights or something, the car hunts forward. When I apply the brake this almost disappears.

    And last but not least, the auto seems to hang on to gears a long time. Is this normal?

    This is my first pajero and I've only just got it on the road as I bought it unregistered. It was a one owner, done 135000kms with service books.

    Any help you could give would be appreciated. Oh sorry, I have put injector cleaner through a full tank of fuel so this might affect the hunting phenomenon I described above.

    Sorry ... there was a bit of a shopping list in my post. I'm pretty sure the whining noise is the rear diff. It is fairly faint at the moment. I think it is the crown wheel not meshing properly? Does anyone have any ideas about a fix and how much it might be? I went around and spoke to Wombat in Ringwood and they were very helpful. It just seems strange that it is only between 95km/h and 105 km/h. OK thanks very much

      Mine has been whinning recently but when it started was only under a slight load at 75-85K, but became mre pronounced to eventually being there at most speeds and also developing on over-run also took it in to the dealer and they quoted a replacement. Dont know if this helps Mine is an 02 NP Exceeep 100,000K also it was due to a dislodged companion (1/2) shaft due to a know issue of a weak holding cir-clip, the whine developed after the shaft was re-inserted and the new upgraded cir-clip installed currently fightinh a warranty claim as the companion shaft cir-clip is a "hotline" or know issue as a design fault. maybe you should get this clip/ companion shaft looked at. when they go they release a fair bit of oil as if it was a failed seal. Apparently the shaft can drift out a little when towing a trailer, on the beach or under sideways load. Mayby yours has moved just a little and stessed the bearing or something -- mine is worse than that and not happy it is a known design fault and they dont want to cover it even tho all I did was drive on Nt Straddy beach witha trailer to go camping made the whole campiong trip a stressfull time I can tell ya. Anyway good luck and this was just somethign else you could consider and look into.

      Cheers

        The NJ rear axle is different from the NP - solid axle, no 1/2 shafts.

        Pagerow have you had 4WDs before? At times the tyres can make a noise that's similar to drivetain whine. Just a thought.

        My original Pajero experience - '90 NG Superwagon, 3.0 V6 manual bought new and kept until 1998. Great vehicle, no problems apart from the noisy valve lifters typical of that engine.
