V6 transmission whine
My 98 reg 166 3.0 V6 with the 6 speed manual has a transmission whine, that sounds little bit like a straight-cut gear set. As the problem is present through all 6 gears, I'm guessing it must be a problem with the diff.
Would it be a false economy to try and source a 2nd hand diff, or complete gearbox to rob the diff from? I know most members would probably suggest Q2ing it, but I don't need an LSD. But I would consider it if was deemed bad sense to fit a 2nd hand diff, and if a new OE item was comparable in price to a Q2 (I genuinely have no idea how much a new OE diff costs).
I really need to strike the right balance between doing this cost effectively, but doing it right. It's going to be an expensive job either way, I appreciate that.
And I suppose the most important question is, should I really be concerned by this? I've read that diff failures seem to be common on V6 models, and I realise they can fail spectacularly. But I don't drive my 166 hard, nor does it do great mileage.
