Best guess? It was just it's time. After 15 years of abuse it gave up. The doubler and 4.77:1 low range gears didn't help. Neither did the v8... or 36" tires
I did break a 21 spline t case input gear that was from TG. It was a design flaw. It broke at a hard angle. (Stress riser) the revised gear had a nice smooth radius that eliminated that stress riser.
21 or 23 spline wouldn't of mattered here. MC no longer makes a upgraded mainshaft. The one I broke was oem cryo treated. Now I have a TG/Longfeild chromolly main shaft.
Why we didn't do this sooner is beyond me. Post your pics and stories here.
