I just pulled the third member out, it was whining pretty bad, under power or off power it still whined. 
The housing is full of little bits of metal, and the gears look bad. 
The teeth have deep scratches in them, you can catch a fingernail in them, every tooth front and back.This is after 4000 miles on new Richmond gears (proper break in was followed and gear oil was changed after 500 miles)and Timken bearings, the bearings feel okay, roll smooth and easy. The guy who rebuilt this third member told me before he built it that he had had some bad Richmond gears and suggested another brand that he had good luck with, they were cheaper too. I had him use the Richmonds. My Question is, Have any of you heard of Richmond having a bad run of gears? ------------------

JimO {project66} had a problem with gear noise with his Richmond gears.https://mustangsandmore.com/ubb/Forum1/HTML/005996.html I don't know what became of his situation. ------------------

If they were noisy from the get-go there's a pretty good chance they weren't set up correctly. Did he set the correct pinion depth, backlash, and check gear pattern? They weren't drag gears (i.e., soft) were they?

For what its worth, the guy that built my son's rear end would not use Richmonds. We suggested them but he said he would not use them unless we insisted and agreed to no guarantee. He used Precession gears and they seem to be doing fine.

These are not the soft drag gears, and the setup was correct, I checked the backlash and pattern myself to double check him before installing it. The noise didn't start until about 1000 miles and has continued to get worse. The backlash is still correct. Oh well, another pile of money flushed down the sh**ter. Do you think Richmond will warranty them?

You may have already looked at this, but check the case around the smaller pinion bearing. This is the thin area of the case that surrunds that bearing that often needs to have clearance ground for the ring gear. The cases tend to break there often and the rear gears will just howl. It also wears the heck out of the gears in a hurry. Just figured I'd mention it in case you haven't looked there yet.

One other thing to check is the backlash in 4 different places.... 12:00, 3:00, 6:00 & 9:00, respectively. I've found gears to be bent and not be able to get it setup right.

The 6.14 Pro Gear that I broke earlier this year after 40 passes was a Richmond.
US/Strange Gear replaced it.  ------------------

I talked with the guy who set up this gear for me. He said he had already heard through the "grapevine" that I had trouble. He told me he had about a dozen Richmond gears stacked up, all bad. Mostly 12 bolt GM gears. All of these were done after mine, he did mine in March of this year. He has also sent some back to Richmond to try for warranty with no luck, they said he set them up wrong but would not tell him what to do any different.  He said out of 8 or 9 sets he sent back none were warranteed. On the good side, he said if I pay for the parts that he would build it at no charge. Andy and I have known each other for about 20 years, he only charged $100 to build it the first time. I'll at least take him to lunch if he won't let me pay him. By the way, he recommended Motive gears.

hmmmmmm, I'll be dipped. I built my 9" T-loc with 3.70:1 Richmonds, set the lash & pinion depth per Richmond specs, checked the lash at several positions (as suggested earlier) and no matter where I checked it it was within .001 . I too folowed the break-in procedure. I am running synthetic 75w-140, and I load test the drivetrain each time out. Almost 1000 miles now, and not a peep out of the rear end I do find it disturbing that Richmond wanted nothing to do with it. I'd love to see a pic of the ring/pinion... got access to a digital camera? ------------------

I don't have a digital camera, but I may take some pics and scan them in.
I hit the 1000 mile mark while doing the Power Tour, I had to drive another 2000 miles after it started the noise to get home. It was quiet before we left, about 200 miles later it was beginning to whine.

Keep your fingers crossed, Todd.  Sounds like a heat treating problem Richmond doesn't want to own up to. They're lucky they are in the performance industry. It's tough to get away with that in other sectors. ------------------

Boy, you're not kidding I haven't driven it any farther than about 50-60 miles at any one time, certainly no sustained Power Tour trips (I'm envious ). A little horsepower , a four speed and a heavy right foot  aren't exactally nice to drivelines, but I'm counting my blessings so far...
I'd not heard anything negative about their product (until now) or I'd have thought twice about it. Makes me want to yank the 3rd and have a look ------------------
