Diff Is Gone

[FTS]

Once the issue is identified as the clutch packs in your case BMan, I don't think we ever thought that the Guard "internals" had failed you, by that I mean the ramps. Clutch packs will wear out of course and at least will need re-adjusting from time to time. I am not sure I understand the breake-in "issue," but no worries.

Similarly, the Porsche diff internals may very well be perfectly fine on my car, and it really is just the clutch pack that needs to be replaced and pre-load to be adjusted. So, Porsche vs. Guard diff --> the same function IMO. I do not know if Guard, OS Giken or who ever else is more "durable" as a complete unit, but at the end they will all wear most likely, nothing is permanent, similar to brake rotors IMHO.

Any way, we'll see how your unit continues to perform and once I receive the new clutch packs from my dealer and we open up the diff, I'll report back about the Porsche "internals."
