My Truetrak has about 40,000 miles on it with heavy duty axles, I lived the D35 dream, Sheared the axle spline right at the case and pieces of it took an adventure through the spider gears, wasn't pretty. Went to DTS in warren and bought the truetrac and axles and set-up kit and did it myself, 3yrs later still no issues, I'm not an extream off roader but when it happened I bought what they (DTS) suggested for a D35. I really appreciate the patience cause I new the locker thing with you guys was probobly overcooked but i didn't see anything satisfactory in the archive so I asked to see what you experts would suggest. In my trade (Machine Building) I have built all kinds of precision stuff and can rebuild anything on that vehicle but applying what works on a jeep, well all of you people are tried and true and I am always hoping to learn.
