I'm into the differential portion of my resto now and I have a question about this end play. I searched the archives and correct me if I'm wrong but the general opinion is that less than .010 is good and anything over.030 should be looked at. I have .036 and .024. I did a torque check of the clutch packs and it is well under 20ft/lbs(thats as low as my torque wrench will go)and with moderate force, I can turn one yoke by hand while holding the other so that tells me that my packs are bad. Now the tricky part...how do I tell if the yoke is worn to a point that it should be replaced? There is wear but they look like any other Chevy axles that I have seen so to me they don't look bad. Is there a good way to tell the amount of wear on them or do you think replacing the clutch packs will bring them back into "spec"? Thanks.

Re: 69 side yoke end play
Greg----
Look at the ends of the stub axles. If the ends are worn enough that the chamfer is gone (or, mostly gone), then they need to be replaced. If most of the chamfer remains, they're probably ok. Keep in mind, though, that really any wear is enough to prompt replacement at rebuild time, when the unit is out of the car. That's because the axles are case-hardened and the hardening is usually quite thin. So, once the wear gets through the case hardening, it will progress MUCH more rapidly. While the wear might appear somewhat slight now, it might be the "important part" that's gone.In Appreciation of John Hinckley -
Re: 69 side yoke end play
Thanks Joe, It looks to me that there is still a reasonable amount of chamfer left but that is where I run into a problem in that I don't have a new one to compare it to. Would there be a dimention from the end of the shaft to say the end of the chamfer or some other reference point that I could use and then compare with a new one? If some one could post a dimention like this from a new one I would really appreciate it.Comment
