I have a 1990 fullsize Blazer with an NP241 and a 700R4. I was wondering if anyone else has to inspect the (4) T-case to transmission bolts on a regular basis. Every month, (even sooner if lots of wheelin), or so I find my T-case leaking tranny fluid. Upon inspection I always find that these bolts have backed out. I have tried Locktite but to no avail. My driveline angles are with in one degree of each other so I don't believe that is the culprit. Any ideas????
