OK, now I've got the engine replaced it was time to sort the other faults. Most were minor and now done, but there's a noise that's driving me nuts! Been steadily getting worse over the last year. While driving, there is a constant donk, donk, donk. Only while moving, it is fairly quiet in a straight line, bit more noticeable driving left corners and very noticeable on right corners. Varies with road speed not engine speed or which gear I'm in, still there if I coast in neutral, doesn't go with brake application. Guessing it's donking about 2 or maybe 3 times to each road wheel revolution. I can estimate it's coming from the front of the vehicle, but hard to tell, though I can slightly feel it through the steering wheel and the floor, especially when going round roundabouts. No shaking of the wheel or anything that drastic, but can feel the donking. Easier to hear with the windows closed.
Can't detect any play or roughness in any wheel bearing front or rear, prop shaft UJ or diff/gearbox flange (at least not evident by hand), though the front left wheel bearing (and CV) were changed. Noise persisted. Mechanic friend swore it was the front diff, changed that for a recon unit, noise persisted. Ahhhhh! What's making my donk, donk, donk????? I've even changed the transfer box front output shaft bearing as there was slight play in it. Wasn't that either. I don't think it's the viscous coupling as there's no tyre scuffing or squealing on full lock in car parks etc. I'm guessing it's something on the front as changing steering input alters the severity of the noise. So what is it???? It's driving me nuts!!!
