    I tried to install the ring gear on the open cattier I have and I bottomed out the bolts and still had about 3-16'-1/4" gap between the ring gear and carrier. I did not have lock wwashers installed on the bolts. The bolts were from Randy's R&P specifically for installing 5:13 gears on a standard 4.56 and lower(numerically higher) carrier(I only got the bolts and didn't notice the lockwashers on my 3.73 setup until the bottoming out of the bolts occured). Do I have the right carrier or are the lockwashers mandatory and the cause of my problem?

    Pic one is the 3.73 carrier, pic 2 is the 4.56 and lower carrier with measurements, and pic three is the 3.73 carrier again with measurments.

    You are backwards. The thicker carrier is for 4.56 and up and the bolts are longer for the 4.56 carrier that is why you are bottoming out before the bolts are seated.

    You should get new bolts if you are using the thinner carrier.

    In order to install 4.56 and numerically higher gears on a 4.10 and numerically lower carrier you need thick gears. So with that being said the 1st and 3rd pic would appear to be a 4.56-up carrier and the 2nd pic would be a 4.10-down carrier. Hope that made sense to you.

    I just noticed you are installing 5.13s. Did you get thick 5.13 gears or regular? That could be part of the problem. The thicker carrier is for 4.56 and up gear sets the thinner carrier is used for thick gear sets (i.e. 5.13 or 5.38).

    Well, it makes sense how you say it, but not how it is. The 1st and 2nd pics have a 3.73 gearset on it. Not a 4.10, 4.56,5.13, etc. The ring gear is stamped with 41 11. that equals 3.7272727272 when you divide 41/11. Kind of aggravated here.

    Even if he has thick gears he still has the wrong carrier. With a 4.56 carrier and thick gears the carrier would never fit back into the housing.

    Did you buy the carrier from someone or did you remove it from a known working diff? If you bought the carrier from someone then it may have just had a wrong gear on it and someone sold it to you with incorrect info.

    Did you pull it out of the axle or did someone sell a 3.73 set on a 4.56 and up carrier? The break by the way is 4.10 and lower (numerically) and 4.56 and higher.

    The lower (4.10 and down) will fit on a 4.56 carrier but will not fit in the axle properly.

    The other carrier came with the truck when I bought it so I could go with lower gears

    AFAIK that isn't possible. You need thick gears on a 4.10-down carrier if you wanted 4.56, 4.88 or 5.13's and if you had a 4.56-up carrier and wanted 4.10, 3.73, or even worse 3.08's you would need thin gears and i'm not aware of any "thin" gears.

    Problem Solved!! The previous owner said it had 3.73s in the axle. It has 4.56s. I guess I now have a 4.10 open carrier for sale and two sets of 4.56 gears. Guess i'll have to start looking for an open 4.56 carrier. :mad:

    Thank you all for your help in diagnosing my problem.

    Why not just buy 5.13 thick gears.

    If it had 4.56s and you have thin 5.13s then you have what you need there is no issue.

    None in stock when I ordered my gears last summer, and they cost almost twice as much.
