Topic: Has Anyone checked into other differentials that will fit the Solstice???

[Aspenrose]

Going to take Kenny into the dealer either tomorrow afternoon, or Friday morning. Too many new odd noises coming from the drive train. Sent Moms out to drive him earlier this evening, to get her impressions. Clutch packs.  and probably the exhaust is rattling against the Pro Beam, which just started Monday on the way home from Pittsburgh.

Dave DDM saw his disgusting underbelly in Denver, and while I don't think he's leaking at the seals, the original vent is still in there, so he spews fluid. It makes me ill to think about replacing a junk Getrag diff with another carbon copy. especially when it's coming out of my pocket.

I believe the CTS differential fits.

[Kelu]

Quaiffe has one which fits.
And I don't think our Getrag's diffs are junk at all.

[DeepBlueGXP]

Perhaps get the Limited Slip version that's on the GXP

[Kelu]

Oh, excuse me, didn't thought NAs have different diffs as GXP/SKY RL. My bad.

I remember I saw on a web ecommerce site the Getrag stock one from GXP/SKY RL was more expensive than the Quaiffe lsd. I know Quaiffe is one of the top brands when comes to limited slip diffs.

The Quaiffes were deeply discounted a few months ago. . . .

I've owned several GM vehicles that had well over 100k on the odo, with zero diff issues, and they certainly didn't spew fluid onto the exterior, nor needed repairs or replacement. Sorry, but the multitude of problems with this diff on this platform spells junk to me.

AR,

I just had a flush-refill done on mine. _If_ I have future ills, I'm looking at the Quaiffe.

the quaife doesn't solver the problem of the seals leaking. The stock internals for the lsd hold up to current aftermarket tunes for the most part. If you do agressive wot starts from a stop and shift hard all the time you may cause premature wear on the internals of the diff and the quaife would stand up to it, but it is a different type and i would read up on what it does as depending on how you drive, it may not be for you. Most of the problems are the seals leaking. If you drive hard, switch out the fluid more often and hoep the seals don't leak....a vent leak is a simple fix, seals are a pain for replace...........the cts diff is the same(except gearing i think)...same seal issues, same internal clutch packs.

There is a Kaaz that fits but they don't know it, same one that fits the GTO. Rhys Millen and company figured that out.  Your buddy Dave (Dr. Love) at DDM would be the man to call.

Rich is 100% correct.  The Quaiffe is not the whole diff.  It is only the LSD (limited slip differential aka as clutches) part of the differential.  The diffs in our car are shared among several platforms.  Cadillac CTS, CTS V, STS, STS V, GTO, Solstice all use the same rear end.  There are only a couple things different diff to diff, the front mount and gear ratios.  All parts are totally interchangeable.  I have had three diffs in my car at one time or another.  I have tried 3:23, 3:43 and 3:73 ratios in my car.  I prefer the 3:73 ratio.  I am currently running the updated GXP diff with 3:73 gears and a Quaiffe LSD.  With the LS2 setup I have, you can tell a big difference between the stock diff and the Quaiffe diff.
