Axle 8 3/4 end play adjustment

Not to high-jack, but this may be related down the road (no pun intended). Everytime I drove my roadrunner with the 8-3/4" rear, I heard a clunking noise, almost like a wobble, that seemed to originate from the passengers side of the rear end. The sounds occurs whenever I backed out of the throttle or have my foot on the brake (going down hills, around right turns; it quiets down around left turns). When i push on the throttle and the rear end is under load, the "clunking" noise goes away.
I adjusted the end-play as discussed above, but the noise did not go away much, if at all. I set the axle end-play on the passengers side axle to 0.014, using my dial indicator, after pushing in the drivers' side axle.

My question: Is this too much end play? Could there be something else making the noise come from the passenger side of the rear axle?

Thanks all. (Again, sorry if this is considered a high-jack.)
