Well I added 1 + 1 together and ended up with 2.
One, about a month ago, I did a nasty jump and landed right on my ass. It landed back right side up and when I started off again I heard a clanking sound. Well the rear dogbone was bent and was hitting the bottom of my engine. So common sense will tell you that the rear end flexed causing the dogbone to get jammed between the center tranny diff cup and the rear center diff cup which bent it. Also, my fiberglass reinforcement around my rear diff bearing was cracked off. So that also tells me that the rear end flex jammed the dogbone, bent it, put alot of force on the rear diff cup, and stressed the hell outta the housing.
Two, last weekend I landed on my ass yet again coming off a jump. The car did two to three endo's. I turned the car back over and hit the throttle and was in front wheel drive only. Guess what. The endo's must've locked the rear dogbone again and blew the rear cup straight up out of the diff housing.
On both wrecks I was off throttle when landing so drivetrain shock wasn't the cause. Well, as soon as UPS gets here I'm installing my new diff housing. I made a brace for it which looks like a 1" conduit brace you can buy off the shelf. I'm going to add some epoxy on the diff housing and install the brace. Then I'll drill through the brace into the bottom of the diff housing and put in some 4mm bolts with nuts. After that I'm going to fiberglass the entire area.
