The light whine 45-70 accelerating , if barely audible and not getting louder with miles, is normal. The crunching noise is definately cause for concern. When you changed the fluid did you find metal flakes or small metallic debris in the old fluid?JMM said:Light whine from 45mpm up.
Loud crunching noise on coast-down (from approx 20 mph to stop).
FYI: I tried changing fluid to RP...no difference.
Eaton is one of Dana's biggest competitors along with Meritor. If Dana don't get their act together, Eaton or Meritor will gobble them up. Dana thwarted a hostile take over from Meritor a few years ago. I doubt they could stop them again.CrabhartLSX said:will an Eaton fit in there?

Incorrect. The whine occurs from incorrect assembly, or faulty parts, or tolerances that are not correct. Dana built a bunch of faulty rears. Chances are, the new 06's should not have this problem but only time will tell. The whine could lead to damage further down the road, (gear wear) that is why they are being replaced. As far as exact components: although they are made with the same part number, the parts are not all manufactured at the same time. It could be the gearing got fouled up and is not meshing with other gears inside the carrier.MoreMoonShine said:My '06 is on order, so from what I gather, is this just something to accept (rear end whine)? When they "replace" them, if there's no difference between the factory and the one they replace it with, why bother? They're all made with exactly the same components, therefore the sounds will reoccur, correct??
The time it takes to get a replacement rear depends on the availability. It could take longer depending on how many were shipped from Australia. You cannot track them, you have to rely on the service dept for that.goatsandstrats said:I hear it takes 3 to 4 weeks to get a new diff in from GM. Anyone know how you can even check the status of the order.. ie estimated ship date, shipped, etc.
I sure hate to be that long without my car. You'd think GM would stock a few of those diff. over here.
From my understanding it has to come from GM or DANA in Australia to Pontiac Michigan and then to the dealer.
Any one got information to add?
