Just had my front CVs replaced as a pre-emptive strike. And the classic BANG BANG BANG refusal to go is still there. The symptoms are definitely Center Diff. Cold = ok but after a 15 - 20 minute run then the full lock turn symptoms appear.
I'm still a bit skeptical that running uneven tyres will do this, my front KU22's are newish, and the rears are wornish. I'd estimate a 3mm tread wear difference so 6 mm accross the full diameter. You could end up with this kind of difference in treadwear difference just from your style of driving, so if the VC can't handle it - I'd reckon its a design fault, or at the very least a poor design. I'm sure that if you just did freeway kms all day everyday then having the equivalent of a 100W light bulb heating up that silicone will reduce life. But seriously? The amount Subaru want for replacement is bs.
Hi wildotan, it will either be the Centre Diff, or the Shocks. Dedinitely go with Billy Corgi if you need a refurbished Diff, because he does excellent work (at a much cheaper price than Subaru wants for a new Diff).
But make sure you rule out the shocks first.
I had my Centre Diff replaced by the Dealer at a huge cost (before Billy started doing Diff refurbishments), and most of the noise was still there
.
It wasn't until someone suggested spraying WD40 on the top of the shocks, that I could confirm they were the source of the noise. The noise was gone for almost a week
. It's something that's almost free to try, so I can highly recommend that.
Jack the car up one side at a time, spray WD40 on the shiny part of the shock in the wheel-well (lift up the plastic shock-cover if needed). It'll be the front ones, so no need to do the rears. But the noise was instantly gone on my car, no matter how much I drove.
