    Default 2.7 Hilux gearbox/diff noise

    I am the owner of a 2002 Toyota Hilux 2.7 4x4 and I need help. I am the third owner of the bakkie, and I think it has seen some abuse.
    Everytime I release the clutch I hear a distinct "ting" sound. At first I thought the universal bearings on the propshaft was worn. I had these replaced with no difference. Somewhere there is play that is taken up before power is transferred to the wheels. I took the vehicle into Namibia in April and the sound has become more frequent and loud since then. I think it is either the diff or gearbox.
    The question is, what do I spend money on first to try and find the problem, gearbox or diff?
    Has anyone had a similar problem in the past?

    Thanks,
    Frans.

    Hi Frans, I had exactly the same problem on my 04 hilux 2.7 4x4 when she only had 21k on the clock. It took me ages to find the problem. I had UJ's, CB all replaced, diff specialists took a look at it etc. Eventually a small dealership found the fault. Apparently it was the rear suspension, I cant say exactly what was loose but the mechanic said they struggled for hours and eventually after going one by one through all the nuts/bolts on the rear suspension components they found one was not torqued correctly. I put my money on that being the problem..

    During my search to stop the 'tink' I also heard from a guy that had a similar problem. If the flange on the gearbox or diff gets even slightly out of torque spec it makes that sound too. But becareful as these things have a set preload with a crush bearing and I would look at that as your very last option and have a diff pro check it out. If you try tighten and over do it you have to open the diff up. BTW those nuts are peened and its highly unlikely they will come loose anyway

    Thanks for that Bryan, I'll have it checked out by the dealer.

    Forgot to mention that when I drive slowly on an uphill and engage the clutch, there is quite a bit of "backlash" for lack of a better description. That is why I thought it could be the diff that is worn.

    I have owned 2- 2.7i and a few of my friends own them to.If the bakkie is ideling , it makes a hamming noise and if you ingage the cluch its quite.All 2.7i do that its normale , but if you say its getting worse , let someone look at it.You can also contact Hoppy on the hilux4x4 forum , he is in Slaapstad and opened a few 2.7i gearboxes to fined the probleme , but found nothing wrong.

    Default "Backlash"

    Hi Frans

    I have driven various SFA (LR, Safari, Hilux, LC) and IFS (Nissan Tracker, Pajero, IFS Toy) 4x4 vehicles in my lifetime. It seems as if the IFS ones always had this type of "backlash" when letting out the clutch, particularly noticeable on accelerating in low range as well. It was quite alarming on an almost new IFS (newest shape) Hiluxes I drove. This same vehicle is still going strong at >100,000 km, so this seems to be an intrinsic thing with at least some IFS drivetrains and possibly nothing to worry about.

    With regard to your "ping" sound from underneath, a agree it could be the nut on the gearbox end flange that loosened up a bit. Fit a new nut, torque correctly and peen. This is a common problem with SFA Hiluxes as well. The sound is often due to worn universal joints, or plain loose nuts on any of the flanges, but I see you have had those checked out already. As Bryan said, leave the flange on the diff side alone if possible.

    The nut on the centre bearing is also peened, so should not work loose, but maybe worth a check as well?
