My son and I we're heading home from lunch and I thought it would be fun to let him drive. I pulled over and he took control. He had trouble with the whole clutch, brake & gas combo, after his 3rd stall he gunned it! CLUNK...Stall...We both looked at each other and I said something broke. I got out and told him to try again. What I could see was a spinning rear drive line with no forward momentum. I drove the 1/2 mile home in 4 Hi. The best I can tell is something in the rear 44 failed. I'm going to open it up but in the meantime I was hoping for some feedback. He feels awful but I think it's funny...Heck, it's 42 years old, I'm just glad we made it to lunch first!
