Post by jzava50 » Wed Mar 28, 2012 6:15 pm

how common is it to hear a whine from the rear end , is that a sign of its end ?

How many miles? Stock gears? Could just be something as simple as being low on fluid.

It's a hawk I'm looking to buy, it's an 02 with stock gears and he says it's a fairly common problem , says the fluid is fine...

How does he know the fluid is fine? How many miles? Does it have the optional SLP differential?

Could be the gears.

PS - it isn't a 10 bolt main. :wink:

Find out if it had the optional Auburn Differential.
If so, it's not really 'common', but it is typical because of not changing the fluid.
Mine had some minimal noise when I first got it with 27k miles on it.
I changed the fluid per recommendations & it was fine after that.
Have done it again since then & it now has about 54k miles on it.
Maybe only 4k since the last change.

I need to find the OE/Firehawk owner's manual somewhere, but it's recommended to change at pretty short cycles/miles if I remember right. (This is in reference to the Auburn option only.)

I don't think I'd agree & let him say "it's fairly common" issue.
It's an issue because of someone not taking care of it properly, IMO.

Two questions for him.
1) Does it have the Auburn option?
a) If 'No', disregard any further comments.
b) If 'Yes, continue to question #2)
2) Did he use synthetic fluids?

If 'Yes' to both questions, ..., There's the problem.
Nice flow chart?!? :lol:


3) What's the car year & SLP number?!?

Crap, that doesn't fit into my flow chart very well.
