What are my chances?

[blockhead83]

I've just picked my car up from the local ford dealer after having the bushes replaced in the diff,axles seals replaced, a service and a few other bits and pieces.

I got the ford dealer to do the bushes because they were charging $750 and everyone else quoted over a grand.

Anyway I notice on the way home that the diff now makes a heap more noise. I know that the new bushes will transmit a little extra noise into the car but this is a lot louder than it was when i dropped it off. Diff whine sounds like a taxi with 900,000 on it now. Before the work was done I would have said it was reasonably quiet for a falcon with 140k's on the clock.

I rang the dealer straight away and voiced my concern, they sort of laughed me off, when I laboured the point they eventually said bring it in tomorrow and they'll look at it.

I can see where this is headed allready "that is normal noise"/ "no it's not". "it's just the new bushes"/"no it isn't"

Even my girlfriend noticed and I haven't been on the highway yet.

Do you guys think I have a chance of getting something done or am I just going to give myself heart burn and frustration for weeks?
