Just got done reinstalling 4.56's in my rear after the pinion broke. Basically an all day affair since I wasn't at my own shop and I had so much "clean up" to do because of metal bits.

its finally warming up and I'm going to finish up my front gear swap. I have the whole diff (third member really) and I'm going to be setting it all up. I plan on getting an Aussie locker for the front. Should be pretty nice.

no pics yet, i'll have some later today. im hoping the factory pinion shims will be the right thickness for the pinion depth, cuz i dont really want to keep pulling that bearing off to add/remove shims...

Not sure of D35's, but on 8.8's you generally need a slightly thicker pack. My original shim was about 0.028 and I'm using 0.032 on this one. My Yukons required about 0.034 to 0.036 if I recall correctly -- it was a couple of years ago.

I hope you guess as well as I did, lol. I was blessed to get it right the first time in both cases. I had read about needing to use a thicker pinion shim with high ratio gearsets in 8.8's and so I tried it. I'd be clueless on the D35.

I had to do my D44 a couple of times to get it right.

Adam, you're not that far away from me. But we'd need another axle to work on. I'm not taking mine apart again if I don't have to, lol. I'd be glad to show you though.

I really don't know with the Dana 35. I only saw references to the 8.8 about going up in ratio and thickening the shim a few thousandths. It's a crapshoot.

well got the front set up, had a .050" shim pack and the factory carrier shims, came out perfect, got everything cleaned up and ready to assemble. tomorrow i gotta pass by ford and pic up my pinion seal and the rear shim kit. its not bad once you understand which way you need to shim everything to get a good pattern.
