Just broke drive shaft.

In 1st gear, put it to the floor then clunk clunk. Looked under the car and there it was hanging, twisted it like a tootsie roll, luckily my safely loop saved the bottom of the car from getting beat up.

I was thinking about checking out what Machine Service Inc on Stoughton road has to offer before I went with a aftermarket company. Anyone ever deal with them?

I did maybe 14 years ago, so I think things my have changed since then. GF at the time had a "friend" shorten her drive shaft in his garage while I was away... she couldn't figure out why it shook violently They fixed it all up.

they did mine in the vette and ones for our pulling truck. never had one failure

and a great price too. they did the one in the vette for less then $300

Had them shorten the drive shaft on the kit car, seems like a good job!

I deal with Randy or Wade over there for all of my driveshaft repairs/builds/balancing. Excellent work at a good price!!

Machine service is top notch.

I will have to give them a call on Tuesday.

+1 for Machine Shop Service!

Had sometime to take the drive shaft out, pictures below. Unfortunately there was more damage than I had initially thought. The rear is toast. The pinion is completely locked up, pretty sure thats why my drive shaft broke. Also can spin both tires in opposite directions. To hot to dig into it further, but if the rear turns up to be dead I think I am going to build an 8.8. Eitherway the car is going to be down for a while. FTL.

dude that sucks.... guess it is just a reason to upgrade

Twisting driveshafts? Must be a racecar.

+1.

When I saw the pic's I was going to comment that he must have the only bulletproof f-body rear axle in existance, but then I see he does not. If you need help with any OE parts, let me know

Turns out the limited slip was the cause of the failure. Looks like it let loose then some of the parts got wedged between the pinion and ring gear which caused it to lock up and and the drive shaft to be twisted.

This is why 7.5 rearends suck.

Thanks GM for putting the same rearend in my V8 car as a 4 banger pick up.

Yeah thats not good when they leave little springs and twisted metal in the bottom of the housing! Looks like some one needs to upgrade to a moser Dana system.

RACECAR!

That sucks!

damn man that sucks.

I am thinking about saying screw it and purchasing a 9" housing and coming up with the 3rd member. Anyone know someone who sells rebuilt 3rd members?
