I am done with my 9 inch...10 bolt going back in
for now. I don’t know if I am going to sell it or just keep it for future use. For right now I am done with the danm thing. After multiple ring and pinions and all the other problems I have had (bad Moser axle) I cant take it anymore. The noise this thing makes is just horrible, the bad thing is the setup is completely right. The housing is straight, axles are straight/ the right length, and the center section is good. I actually bought a pinion depth tool just for a 9 inch Ford, and used it to check my work and I was .001" from the measurement etched on the pinion just going by pattern. The gear in there now is a U.S. Gear 3.90 Competition Ring and Pinion made right here in the US. Its pretty funny because I can setup 10 bolts in my sleep and make them quiet. I just setup one for a friend with Motive 3.90's and his is danm near silent.https://ls1tech.com/forums/gears-axl...t-weekend.html So thats what is going back in my car. I do not race my car so I figure I do not need the danm thing anyway. I know a lot of people talk **** on the Motive blue box gears but that may be the ticket to a quiet 9" the Blue box are a street gear. Almost all 9 inch ring and pinions being made a race gears, because thats what everyone wants a 9 inch for in the first place. This adds to the noise. Also the 9 inch pinion rides further down on the ring gear which adds strength, but makes more noise.
So back in the 10 bolt goes. This is my 10 bolt with a Ratech install kit, Motive 3.90, Summit Racing girdle and a Ratech pinion spacer. I used my case spreader and pinon depth tool and it went right together. This girdle is really nice, I thought it would be a made in China POS for $129.00, but its made in the USA and came with stainless 12 point ARP cover bolts.

If you can set up a 10 bolt a 9" is a cake walk. I'm not following the chronological order of the 9" problem you have, but let me assure you a 10 bolt is a bitch to set up correctly. Not as bad as a Dana but nothing like the ease of a 9".
If you start with a brand new ring and pinion, I can walk you right through your 9", one easy step at a time. Your big decision is crush sleeve or spacer. Tools needed are an inch pound torque wrench, a dial indicator W/ some sort of base and standard hand tools. And that's it.

Nice move, for as bad as people make the 10 bolt out to be, on the street I have yet to see anyone break one around me with occasional trips to the track, just wearing out the bearings in OE 10 bolts. Of course these are H/C cars. My last car had 200k on the stock 10 bolt and I had it rebuilt with 3.73s, no issues. Mine is going strong in my new car at 127K and I plan on rebuilding a 3series diff and putting in 3.90s

Sucky, I have followed your build for awhile. I don't blame ya for swapping back. If you don't beat the car that hard might as well keep the ten bolt and save some weight. Just sucks for you on the wasted investment, maybe you can get some of your money back out of it.

The majority of my friends have autos, I take back my comment I do remember 2 people breaking theirs but they were making over 700 and were sticks. But I'm with the op unless you race or make serious power I see no need to upgrade, especially with an auto. They do fade over time if you beat on them.

Its sitting on my garage floor right now, I pulled it today. I might pull the center and snap some pictures of the pattern.

Find an old Ford car or truck service manual. Not a Chilton's or one of that type but a real Ford manual and look through the set up procedure for a 9". Look at the gear patterns and how to set pinion and carrier preload. You may see something you missed.

10 bolt
Hey guys I got a camaro with a 10 bolt,my rear makes a constant noise,so I had new gears and all new bearings put in,while in there my mechanic said that I have one bad axle where it rides on the bearing,will that axle cause a noise,cause he set the rear up right?
