    i know, i know..go 12bolt or even better - 14ff, but for now, until i figure out exactly what i want to do to her, i need to fix my 10bolt, if i can. If i raise the rear, i can push and pull each axle in and out about 1/4 inch. wheel bearings fine...no play side to side. when i'm slowing to a stop and she shifts from say 3rd to 2nd, i get a nice "clunk" coming from the rear. ujoints are all replaced. anyone have an idea why all he play and the clunk? I'm thinking the clips are shaved and/or worn giving me the play. is there anything else i should look for when i pull the diff cover tonight that might be giving me the problem or anything i might be able to adjust? like i said, just a temp fix now until i do the upgrade next month. Thanks.

    I used to have an 89 S-10 Blazer with the baby 10 bolt in it. I had a C clip drop out of the slot on me one day, I thought it had just worn down too. I bought some replacement C clips and thought I'd get away with a quick fix. It turned out that the C clips didn't wear down, the slot on the end of the axle shaft had worn and opened up allowing the clip to drop out even with the cross pin installed. [​IMG]

    I made a shim using a hardened frame washer that I ground down using a belt sander and lots of coolant to keep from overheating the washer. It took a long time to grind it thin enough, especially because I had to stop and cool it down so often. It was kind of a hokey repair, but it did work and I never had a problem for the year or so i drove it like that.

    Your carrier bearings could be shot. Remove the cover and see if you can move the carrier around. If you can the bearings are junk and the housing may be also. Usually when the bearings go you will hear a groan under power. Remove the cover and have someone push the tire in and out and you should be able to see the culprit.

    Thanks tRusty &amp; blazbrnc for the replies. I'll check it out tonight if i get a chance to get in the garage for a bit. If not, def tomm night and repost. Also, It seems like it almost freewheels when i'm coasting to slow down right before the "clunk" when she downshifts. Maybe it's just completely shot and she's calling, begging for a 14ff!! Thanks again.
