How often should I change my oil in the rear diff? And how often should I change the Clutch fluid.

Well, that depends on your driving habits! IF you go off-road quite often or pull a heavy trailer, you want to change it once a year. If you don't do either of those things then once every 30,000 miles is fine for your rear DIFF. fluid!!

Now, for you clutch, you want to change that every 35,000 miles.

just a note. my 97 3.55 uses 75/140 synthetic (rear diff is a non LS, buy additive if you have a LS). In houston area it is not that easy to find. i buy it at o'rileys auto stores. Sta Lube is the brand.
