Pattern looks good, backlash is normal.

You have had a lot of rebuild practice for 1 vehicle.

FYI, I run poly bushings all around. There is no rear end noise is transmitted into the cabin. Totally silent. There is a tiny bit of transmission noise, but barely noticeable. The MKII Supra is another story though. No matter how you build the diff it hits a harmonic noise around 50-60mph...

Yup, still do them on an as needed basis.

You have some bad luck with these gear sets. Where did you get this one?

How do the gears look?

Either is fine, if on the highway just vary the speed. Key is allowing the gears some heat /cool cycles. So they don't overheat, short trips.

Drive it for awhile. It should quiet down.

Ohh, sorry I thought you meant just pinion. You should be good to go then.

Are you lightly oiling the bearings with gear oil before readings?

Preload is too high then, this does sometimes happen with a new unused nut. Threads are stronger than an old used one. Starting in/lbs is the number to target @ ~12-13in/lbs once the nut is fully torqued down. Re-do the shim stack and try again.

Yeah its right on the edge. I don't like how many 0.1 measurements were in there though. Do you have around 0.001" of runout on the ring gear when you spin it in the case? Might be something to check as well.

Too bad I can't just hand you one of mine. 0.115" (2.921mm) PN: 90201-52012 I have 5 on hand currently.

Pattern is good. Backlash is a bit tight, but you maybe? Could get away with it. If it were me I would shift to 0.0055", swap out with the proper side shims. When the diff components heat up they expand slightly and the backlash decreases. By how much exactly? Don't know. This is where having...

Those numbers look very good. Interested to see your pattern and backlash

Should be fine.

If its just a blemish should be fine.

I am in agreement on your preload targets. I would shoot for 13in/lbs on pinion breakaway, with pinion nut somewhere around 160ft/lbs. Carrier bearings at 5in/lbs is a good target. The pinion shows good pattern because it's a hair shallow and the "comet tail" is pulling only a bit to the...

.076" is perfect. Run it. Also the backlash is quite good. I shoot for .0055", maybe a hair higher depending on what I am setting it up for usage wise. What is the breakaway torque on the carrier bearings only?

.076 is the winner. Placement on the tooth is stronger, also known as "competition pattern" Show the corresponding pattern on the pinion, as ring only shows half.
