First, the good news –

Got the axle CV cup back, assembled the driver’s-side axle, then filled the transmission with OEM fluid to break it in. With some rare rain going on though, the test drive has to wait.

With the car stuck in the garage, finally got around to added 15-mm wheel spacers, since I’ve long had tire scuff marks on the inboard panels. Adding the spacers necessitates cutting down the OEM wheel studs, which went fine and while I was congratulated myself on my fine work, my brother called. I asked what his tire-to-chassis clearance is and was surprised when he said less than 1″, which is what I had before adding the spacers. Well nuts. He reminded me that the tires I’m now using (same as his) have stiffer sidewalls (though I don’t know how he knows that), so that’s one variable. Another is that he has roughly 450 lbs on each tire, while I have around 600 lbs on the rear tires due to being mid-engine. Another difference is that my rear suspension is IRS, so the tops of the tires move inboard under acceleration and braking. Between all these differences, it’s unknown how much the tires will squirm around. The irony is that having added the spacers and switched tires, while there won’t be any rubbing, I won’t know why. Oh well.

The bad news, well, I’m not sure how bad it is yet.

When I took my old transmission  to WaveTrac to have them fix their differential design flaw, I expected them to do just that, pop out the stuck axle stub, fix the LSD, then give me a call. Well, they did:

Them: “While we were in there we also found some gear bits stuck to the magnet. We’re sure you will want to fix this so we’ll hand it back to you taken apart.”

Me: “No, I want it reassembled, then I’ll decide what to do after seeing the little parts.”

They agreed, I drove up to get it yesterday, and:

Them: “Okay, here it is, reassembled but not sealed.”

Me: “huh?”

Them: “We’re sure you’ll want to take it apart, so there was no reason to seal it.”

That isn’t what they agreed to do… Anyway, when they handed me the parts, they did indeed look like broken gear teeth. After thinking it over and looking at them again later, I’m not so sure; the “teeth” on them are really small, flat-topped, and not helical. I’m wondering if they’re off some sort of slider component, though why that would break instead of the gear teeth is a mystery.

Anyway, the first step is to identify what these bits are. At best would be hearing they’re of no consequence (yeah, I know) and at the other extreme, it gets shipped to a tranny shop and torn down – again.
