Got the detroit in the 9". Only took me about 18 hours working in the corner of my shed with a small led light (electricity not run to the shed).
I've never done gears before so invested in a magnetic dial indicator, inch lb dial gauge, home made spanner wrench, and rented bearing/race press cups, bearing race puller and accompanying slide hammer from autozone.
I original was going to run a crush sleeve eliminator but the one that came in my kit was too thin and didn't have enough shims to even contact the bearings on the pinion. I went through 2 crush sleeves before find out a trick to make it easier to crush them.
I assembled the pinion and bearings into the Daytona pinion carrier and push the whole assembly in my press. Then pressed out all the slop until the bearings were seated in the support. Then put the yoke in my vise and used a 3ft breaker bar to tighten the pinion nut until I had resistance turning the pinion support.
I would tighten a little and then check the preload on my dial indicator. New bearings should be between 15-30 inch lbs in at 26.
Then adjusted backlash and verified on multiple sections. Spec is 0.006-0.010" and I'm at 0.008.
Then I ran a pattern with the marking compound and was able to get a good pattern. I started off with a 0.020 shim, went up to 0.045 then 0.027, then 0.035, and ended up at 0.039 asy final pinion shim pack.
I then ran a die over the housing Studs and cleaned up the threads. I still need to pull the 3rd member and put on a lube locker gasket and pinion support o-ring. I just stuck it on the housing so once I press on new axle bearings, axle retainer plates, axle bearing seal, and axle bearing retainers I can put the axles in and get my brake caliper positioning to weld on the caliper brackets.
Also holy crap caliper banjo bolts are ridiculously expensive. Almost $35/ea. Luckily Speedway Motors sells a stainless line kit for my rear calipers that was $49.99 and came with 2 lines 2 banjo bolts and the required tabs.
Once this is under the XJ I'll tackle the d30 front axle gears. I may just pull the front axle and do it in my shed because I need to cut off the old trackbar mount and weld on my new one from Ironman4x4 so I stop getting bumpsteer with my over the knuckle steering.
