It is one of the lowest stock ratio cases you can get, strong internally, weak externally cuz of the al cases.
Make sure that the cones are tight - if it is leaking there from loose bolts you can mess up the cases and never get them to seal right.
Keep it full of ATF and it will more than likely last for many years to come. The 241's usually die from lack of lube or rocks - seldom from too much power.
Mine NEVER gave me a lick of problem, and it ran the last part of it's life clocked up flat. Keep it full of fluid, shift it into 4wd every now and then, and it will stay happy. If you plan on wheelin with it, clock it up and build some protection around it. the aluminum is SOFT and WILL CRACK if you aren't careful.
