G'Day all, this is a difficult one, loud random sreaching noise coming from my Navara.I shall supply as much detail as possible.
Vehicle is a 1999 Navara Dual Cab 3.2 diesel with 195,000km, engine serviced regularily, not much else touched though.
It sounds like a belt screaming, but its not, although it did start when I had a new set of belts fitted by local 4bie
shop, its been back 3 times, belts are tight n they say noise not belts but want vehicle for a day at $80/hr to diagnose..... not happening.
I expect them to tell me whats wrong n how much to fix it, not charge me just to tell me whats wrong, so I shall do my own diagnosis, which i'm normally quite good at but this one has me beat.
I thought clutch release bearing, but clutch in / out has no effect.
Brakes on / off no effect.
Its not engine, as one day when doing it, I stopped engine and rolled along slow n noise still there, so rules out belts, which you'd swear it was.
Its totally random, i cannot recreate it at will yet, happens uphill / downhill, on RH bend, on LH bend.
Totally stopped n went away for about a month, so I gave up, now its back though.
Vehicle fine in all other areas except noticed occasionally a bit of a snatch when pulling away in first, like you let fot off clutch too quick, so maybe a clue there? or poss just a bit of transmission wind up and not associated.
4bie guy said poss tail shaft bearing or wheel bearing.
Any pointers appreciated.
Rgds
