Possible diff problem

[Mick Howes]

I may have a problem with the diff on my 95LT1, taking it to the place that has done really good work on my car but a bit worried about the possible cost involved if the diff needs overhauled or replaced. My question is, what sort of cost would either repair or replacement be?

What type of problem you are having with the diff ?
When was the last time the diff fluid was replaced ?
