Mine is heard best from 44-46mph. It was pretty loud when I brought it in and my dealer swapped it without question. I had NO mods at the time. Dealers vary greatly on mods...so to be on the safe side make it stock as possible before you take it in. My new rear developed a slight whine already and does not seem to be getting any worse. It's NOT the new part number though...the new ones may be standard replacement now...dont know.

exactly like you wrote it!!! That IS the whine.
My dealer said no prob on replacement BUT.......... the computer still shows the old diff #.
Lindsay caddy says if you order the diff the new part # arrives. I am a bit skeptical so I'm holding off until the computers at the dealers reflect the new # or it is comfirmed that all orders will be the new Part # regardless of what the computer says!!
Only way to tell is to go into the dealer and see what they say to you.
Good Luck to you,

Just had the 06 Diff installed in my car yesterday. Looking at the diff, the one thing that stands out is the ribs are much thicker. They did insist that I break it in properly for the first 500 miles. No fast starts, no constant speeds, etc. We'll see. But for now, it's quiet as a mouse.


With my old diff, the whine was most noticable under light loads around 46-52 mph. When you press the clutch pedal - presto - the noise dissappears. It was also leaking from the drivers side housing.

If they look they will find it. Which is why I'm wanting to get a new CPU and have a Steath tune on that, leaving my CPU just as the shop left it.

All it might take is them wanting to update the CPU with the latest software like any GOOD shop would do.

FYI: I have the same thing on my '06. Heard it today.

Starts at 58-60 and gets louder up to 65 and stays constant...

Taking it in on Monday...

Mine went in to the dealer yesterday for the whine, haven't heard anything from them yet, but the longer they take..... I'll assume they're putting in a new one.
We'll see what happens
