So I was driving home last night and had a small explosion happen under my car. Turns out my drive shaft snapped. I was under full throttle and going about 70-80 MPH when it happened. I've got some pictures of the carnage.
From the driver's side:
Passenger's side:
This is from the back. Notice the rear section of drive shaft jumped up over the exhaust and wedged itself in:
Here's the broken off end of the rear section:
I was trying to pull the front drive shaft off and noticed the transfer case wiggling so I put the camera up in and took a shot:
I ended up having to pry the shaft out with a wrench. It had managed to stick on pretty well which meant I didn't have to hunt any parts down along the road.
Here is the section that broke off:
I've got another t-case housing I can use to repair that. Part of the reason it broke was that it had rubbed against the exhaust a bit at one point and scratched this area up a bit. That made it the weakest point in the shaft. The wall thickness on the pipe seems a little thin though. This is a two piece shaft (now three, haha) so the section that broke is pretty long. I'm wondering if any of you wise folks have a knowledgeable suggestion on wall thicknesses to run. My mods list is current. For now I'm only pushing 13 psi above sea level atmosphere but I'll be bumping it to 20 or so in the near future. From what I hear with the 2.4 at 9:1 compression that should be good for 350-400 ft. lbs. of torque. I'm not sure how much shaft I need to handle that given the 53" length.
