Hi all,
newer member, looking for help with my front end project. I bought front and rear axles, 3.73's, to replace my 3.07's. The rear pig was mint. The front I wasn't so lucky. All the bearings were rusty, all seals dry and cracked. I have all new parts for the front diff, minus the gears and carrier themselves. I am at the point of being ready to bolt it all together, all races are in place, etc. I have observed that neither diff (original or my swap) had shims under the caps, are they required? Also, is the outer pinion bearing (closest to driveshaft) supposed to be a slip on fit, or a press fit? My new bearing wants to be press fit. I have read a few different write-ups on diff overhauls, they all differ. How worried do I need to be about tolerances/figures such as pinion depth, pinion bearing preload, backlash, etc? I am looking to set the diff up myself, as I'm a broke college kid. My diff will only be used used low speed, wheeling or snow, so I am willing to settle with good enough as long as the thing will hold together. One more question, neither of my diffs had a retaining bolt in the spider cross shaft, did both lose theirs somewhere along the way, or is one not required?
Any help will be appreciated.
Thanks,
Erik
