5SpdCab, Nice new engine stand!! Something to consider though, the mounting bolts for hanging that four armed mounting plate to the back of the block/ t-mission case flange need to be heavy grade, like grade eight or better. Also, score some heavy/thick flat washers. The tubes for the bolts are sometimes oversized to accept larger dia capscrews, at least they are on mine. I elected to prevent pull through by using the thick washers as a combination of end caps and spacers. You can get fender washers in various diameters and thicknesses and to get the right O.D. you just have to drill the I.D. to what size you need, 3/8ths or ? and run with that. I have nothing hanging off my stand so maybe I'll pop a couple of 'pegs tomorrow to illustrate what I am trying to describe here. The current bolt set is meant for transmissions so they are long enough to get through the mtg ears and have enough protruding thread that a heavy hex nut can thread on completely even with washers underneath it. Using the washers keeps the ears from being chewed up by the nuts.
On the rear end noise, the last time I went hunting for one of those noises, it turned out that one of the ring gear mounting bolts had backed out. Surprise, it was left hand thread!! Surprise, surprise, I ended up having to deal with the bolt that held the crosspin in place. Fortunately I got lucky and was able to fish out the stump of the pin. That was all done out on the back driveway; true shade tree operations, on my Ma's Cadillac. it still sits in my garage, under a cover; it's last task was to follow the hearse that took Mom to her final resting place. Not sure if it would even start after so long, Caddies have the oil pump at one end of the motor and the pickup at the other, like the 231 V-6 Buicks did; would have to pull the timer and seriously prime the motor before even reaching for the key. Hope your noise turns out to be something simple or easy or both.
