Rear end bottoms out

Lately I have been experiencing a problem with my 95.5 Rodeo rear end bottoming out over seemingly very small bumps in the road and RR tracks. I am sure it is not the shocks as I have just replaced them and it was doing this prior to me replacing the shocks. Any insight or suggestions would be appreciated.

time for some new leaf springs!

or maybe a loadhandler (I remember this from an infommerial).

Don't know if you're still here, but you may not be bottoming out. To do so your back end needs to travel nearly 4". With that much travel you look like a low rider playing with the hydraulics. Are you hearing a "clunk" when going over seemingly small bumps? I just posted a rear end noises post for an answer to rear end-noise-questions too.

I'm suspecting axle or rear dif, but I can't imagine what pieces could be loose and have the car run like it does.

stay tuned

This is definitely a problem with the rear end bottoming out. I haven't modified the rear suspension at all. I have the proper application of shocks.

I have a 1994 Isuzu Rodeo (2.6L 2 wheel drive) and have experienced the very same issues you have described. I would bet you anything that the leaf springs on the rear end of your Rodeo are just weak form time and travel. The easiest way to address this issue is by installing a set of leaf spring helpers. They are often used to stiffen the rear suspension for carrying the extra weight when towing, but the also will help add new life to worn/tired leaf springs. You can find them sold in pairs ranging in price from $39.99 + from several internet based stores and at local stores such as Advanced, Autozone, Pep Boys, etc. I installed a set of leaf spring helpers on my Rodeo in less than a hour and it made a world of difference, no more bottoming out or leaning heavy in a turn.
