Ok heres the deal, me and Justin (smokkey) are installing 4.56 gears in his 14 bolt and we trying to figure out what the problem is. We are getting 12 thousands of axial runout on the carrier and 20 thousands of radial runout on the carrier. Were trying to determine if the its the carrier, ring set, or the housing before we go too much further. Everything has been very carefully deburred (in between the ring gear and carrier, bearing seats, etc...) We have taken the ring gear off and rotated it 180 degrees, and still we are getting a huge runout on the carrier. The backlash is varying 10 thousands from one side of the ring gear to the other. I would hate for Justin to buy another carrier and have it turn out to be the ring set.

You could check to see if there are any burrs or something between the carrier halves? If its a full float that is.

Did you granade the old ring and pinion if so that could have caused all your runout.I dought it's ring gear i ahve seen it with carrier's.Take ring gear off and install back in the housing,and tighten down your carrier's pre-load,and then check your runout with a dail indicater.That will tell you if it's the carrier or the ring gear.

It sounds like the carrier is fawked. Install only the carrier (without the ring gear) and put the dial indicator to the ring gear mounting surface and see what the run-out is there...If there is any, it's your carrier that is messed up. What did you use to de-bur it...an angle grinder?:flipoff2:
