I was climbing up a rock ledge and hit a lip at the top, the front came down hard ( with a little help from the gas pedal),next thing I saw was the bottom of the ledge and a bunch of gear oil. I do have reverse shackles with factory drive shafts. After reading Krusty's and Jason M's post ,I looked and couldn't find damage from a rock on the t-case. Thanks guys for the info, I'm still learning and all of this helps.....guess I'll get back to the shop to get ready for next weekend......Thanks again...KrustyKruiser said:Another possibilty - I have seen that kind of damage where the front driveshaft "bottoms out" or binds and punches the tcase out. If you have a shackle reversal without a long slip yoke front driveshaft that is a major possibility - under droop the slip yoke can almost fully separate, and then it can bind causing severe trauma to the tcase on compression. Just my 2 cents. But a tcase saver from Reddog is a must for every non-split case!
