4.10 gear install
#21
Backlash was at .014. Now the question is. If I recall Richmond calls for .008 +\- .004. 4.10s going to spin around fast enough to want to set backlash to the looser end to account for heat??

Remove shims from the passenger side and add them to the driver side to get the gears closer and close backlash down to 6 to 8. You'll probably want to move .005 to .010. So maybe you don't have those figures exactly. Maybe you have a .022 on the passenger and .018 on the driver. If you swap those from side to side you've just reduced by .005. Don't add or subtract from the total shim pack, just focus moving a small amount to get the carrier over. You NEED a set of calipers from harbor freight to measure the shims. You can't guess.

You should be rolling patterns with about zero preload on carrier, meaning you arent pounding it in but there is NO slack, so lightly tapping. Then you can move your existing shims from side to side to adjust its position (i.e. backlash). Once it done and complete and ready for final assembly, you need to add another say .005-.010 to each side evenly so you carrier doesnt move, you are just adding load to the bearings to keep things stable and cover for wear in. Which is why its critical to know the shim thicknesses so you can quickly do your math and make necessary changes.

Just a quick update. Got pinion final bearings on. I micd the shim pack. Was .32 if that benefits anyone. And also in the pic is the digital torque gauge I used to setup pinion and carrier preload on both 10 bolts I've redone and it works really well

Just a finish update..Backlash was at .08-.09. After getting the best preload pack of about .007 increase on each side backlash settled at around.005-.006 which i am very pleased with. I know the richmonds in my 95 had some whine and I tightened the backlash just a bit and it quieted down substantially. Contact pattern showed just a bit on the toe of drive side and centered on coast side. However I didn't take too much of it being it already had a good bit of marking paint dried on it. Want to say carrier shims were driver side .238 and pass was .252. Lucky for me the axle spacer paddle slips right in without hassle at all. Thanks to all for help and input.

So if my contact pattern is good then it is not the pinion could use just a little bit more shim but I need to get my backlash a bit tighter?? Also anyone got any tips or tricks to setting up this solid pinion spacer?? I don't have the used crush sleeve to go off of as the previous gear setup was done improperly. Was thinking of using the new one to get my correct preload and then setting up my spacer based off of that.

Man thats not normal the gears actually bit the carrier I've never seen that before, I hate messing with the 10 bolts period Im glad I got myself an 8.8, putting money into the 10 bolts are so unpredictable.
