[QUOTE="neech, post: 10487603, member: 108165"] Hey all, I apologize for another one of these threads, but I would love to get some input from anyone that has some ideas on this gear contact pattern. I replaced the ring and pinion a year ago due to a ****ed up install via previous owner, and it started whining about 5 miles in on the first breakin drive. I think I put too much preload on the pinion bearings based on what everything looked like on this tear down. So anyway, after a year of not having any time (full time work and grad school) I bought a new OEM diff, OEM ring and pinion, new carrier and pinion bearings, and am pretty close to getting it all back together. The specs as it sits now are: Backlash: .011" (.008 to .016 spec, I read .012 was optimal??) gear runout: .002 max pinion preload: ~20 in-lbs with solid spacer I have .028 of shim on the pinion and the depth measuring tool that I have is coming out to +- .002" of the desired check distance. It appears that the drive is pretty centered with a bias towards the toe, and the coast is off the heel. On with the pics: [ATTACH=full]162755[/ATTACH] [ATTACH=full]162756[/ATTACH] [ATTACH=full]162757[/ATTACH] Anybody have any inpuit? Thanks in advance [/QUOTE]
