set up my rear at work today, 5.13 gears and spool.

spent about 3 hrs doing it completely right and nice, and the housing was already disassembled. all the tolerances are at the tightest side of in spec, which i wouldn't do for a driver, but for off road i'll get the least deflection while being in tolerance. the second pic is reusing the old shims, which is just a starting point. most people just throw it together with the old shims, and this is the result, after taking it back out obviously:

 

 

contact is too shallow, and toward the heel.

 

after setting the backlash i had to start over by adding pinion depth, thus changing backlash, so all in all it takes about 6 or 7 tries before you can assemble with the new bearings and press it all together.

finally where i want it.

 

 

 

so moral of the story is, 6 hrs to set up an axle is about right. i'd like to do a nice write up, but no time on this axle, but i found the best write up i've seen on the net that was just made a few weeks ago, so i can send that out.

5.13? are you running a 4cyl?

[jpdocdave]

naw, and a 4 cyl really doesn't have enough power to push 5.13 gears on the top end.

 

i'm building a stroker jeep 6 and it will have 35" tires, and a crawl ratio way over 200:1 w/ doubler t cases.

I am currently getting 5.13's installed in my Rubi on 35's. I do not have the knowledge or tools to do it my self. Can't wait to break them in.
