I ordered up a Yukon duragrip and some US Standard gears in 5.13 ratio in preparation for an upcoming T56 swap. Well I finally got around to installing them in the driveway today. Got it almost all the way done and was trying to install the axles when I found this... Can't get the pin out of the damn carrier to install the c-clips. WTF???

Anyone ran into this???

There is a bolt you have to remove before the pin will come out.


5.13's with a t56?????????? why
Have you seen what the 1st gear ratio is in a t56?

 

Looks like the bolt is out, but the pin is going to hit the gear.

 

Mathematically, the 5.13's with a 31.8" tire will be nearly identical to a 4.10 gear in an fbody with a 26" tire. And yes. I have seen the 2.66 first gear on T56's. This is going into a 5000lb Tahoe so the mechanical advantage will also help with clutch longevity. That's the theory anyway.

The bolt is out for pin. The pin is hitting the gear and impossible to remove from either side of carrier.

Here's a different angle.

I used a torch to get mine out

 

I'm guessing not proper carrier for that thicker gear set or vice versa. Don't see a solution without changing one or the other.

 

Well I just talked to Ron at Rons Machining Service where I bought the gear/posi package from. I guess the industry standard is to grind the gear down off the corner without getting into the wear pattern. They even have a video on their website showing the procedure. I'm going to remove the carrier tonight and instead of grinding the gear, I might machine a flat along the length of the pin. This way the ring gear stays in tact. Seems like a more logical way to approach this problem IMO.

Interesting. I learned something here as I have never see this problem. But I don't work on rearends though. Thanks for posting about the issue.

 

Same thing happens if you put a 4.56 gear on a 7.5 10 bolt
