I mean you guys can obviously do whatever you want....it's your car. But I would have a really hard time advocating these procedures to the typical novice mechanic. I sincerely hope not, but I would think we're going to see some problems with these gear installs if they are done this way with blatant disregard for ensuring the proper tolerances are measured and adhered to. Okay, enough said, you guys do what you want.... Lastly, setting the parking brake cable with your axles removed is NOT going to prevent the driveshaft from turning!!!! Okay, I'm done! |

No problem guys. Just for time frames... We had my carrier out in an hour and half, and the gear swap took about 2 hours, and the install was an hour... So in reality, you could do it in a day easy, provided you have all the parts and a press.
I really hope everyone's install is as easy as mine was... I don't think I got the "magical" set of gears... but I can't see where there is any need for adjustment.... its CNC'd perfect. I say it goes along with the rest of the car and how GM made it so easy to work on.

He asked me to get an install kit and prepare for shims and new bearings.... well... Good luck finding that... cause nobody around my area had anything... they couldn't event find the bearing numbers for the car including the dealership. Lastly... I set my parking brake to remove the axle nut.. and then took it out of gear to roll the driveshaft when removing the bolts... I guess you need numerical step by step instructions.

Best thing I can say... is take yours apart and see what happens. GM obviously had a plan and if they send you everything you need to do the swap and that only includes the pinion, ring, bolts and crush sleeve... then what else do you need? Unless you foul up your bearings taking it out.

Those thick spacers on each side of the carrier are shims. If the backlash is wrong, they need to be replaced with the correct size with oe or aftermarket adjustable shims. Also the pinion shim in most cases will be correct for pinion depth but pinion depth must be verified always. The crush sleeve isn't for pinion depth, its for bearing preload.

So if I were to have a local speed shop do the swap where do I find the specs for backlash, torques, tolerences, etc? Can someone post them so we can make sure our installers are doing these to specs?

Right.... but what I'm saying is that everything went back in as it came out and in the end the placement and back lash was the same as it was with the original gear with nothing special having to be done. I don't expect that to be the same with everyone but I think alot of installers will be surprised at how precise everything is.

I performed my 1le gear swap. I have all of the special tools available to me. Most mechanics will tell you the same thing I'm about to say. I would rather install the gear set with the factory pinion shim and side bearing spacer to see where I stand. With the 1le gears my backlash, bearing preload and pattern were all perfect. I did have a shim kit available but sold it because I didn't use it.
Your best bet is to take the rear assembly out and let a pro set it up. If you don't, you need a dial indicator, a small beam type torque wrench for setting preload. 1/2" torque wrench for ring gear bolts and bearing caps and some type of marking compound. White grease can be used. A pinion depth tool is not necessary as long as you understand your pattern. |

^ I bought the shim kit from you, and we needed to use two of the shims to get the pattern right.

A DIY guy can remove the diff assy, but reading the detailed step by step of the ring & pinion itself an extremely important step was left out so I'm with you......lets see the results. Quote:
Once the gears are run, if the pinion depth or backlash is off and it whines, odds are it will be noisy forever. Proper pattern and setup is critical. |

If this is your first go at it. Take it to someone who has done lots of installs. You really need to know what you are looking at when you check the tooth pattern using prussian blue. Both front and back side. I've seen them perfect on the drive side but off a bit on the back and then they howl when you let off the throttle. Once you see it once you'll have it but there is a bit of an art to getting them perfect. And you want perfect.

There's no art to it. Just have to know when moving the pinion or te crown what affect it has on your pattern. After your back lash is set of course.

The art is in looking at the ink pattern and knowing it is right.
Edit: And if it is not, knowing by the look of the pattern what to correct.
