First Aid Kit for a Driveshaft

I stick with my original post. You paid for a service and that service is now pretty unsatisfactory. A legit shop will warranty their workmanship. Just sayin'.

+1 on this they should get on this immediatly! FYI : it is 8mm & a 5" long socket style works great. You may have to replace some of the bolts too.

final point of caution - i'm in the process or returning some jobber axles i purchased recently because of a number of fatal issues with them, several of which could have resulted in what you expereinced. please check with your shop to ensure that they used oem parts or at least advised you of the fact they were using jobber; an oem axle is $1k, a jobber is $200 and not worth the price difference.

I know for a fact they were aftermarket driveshafts because the parts were about $200 each, not $600. Do you really think because of that, it caused the bolts to loosen? I can look at see the flanged shaft and the screw holes.

i was going to post this after i got my refund, but the two things i can think of right away are:

1) the dust cap on the inner cv on the jobber axle didn't fix into the boxster transmission flange properly, such that there was a 1/8" gap between the flange and the cv. so, i could see that, even at torque, things eventually working loose as there is room for movement and less thread engaged.

2) a cv can do two things; provide rotation and provide plunge (in/out movement). some cvs do both, some just do one ore the other. on oem axles you have rotation and plunge on both the inner and outer cvs. on the jobber axle i received there was rotation and plunge on the inner, but only rotation on the outer. without the additional plunge, and given the big offset between transmission flange and wheel carrier on the 6-speed boxsters, i could see that being an issue causing additional deflection on the flange, forces outside of design spec, etc.

otherwise, the jobber axles are a weaker steel; when i installed othe oem expansion nut it actually milled the threads on the jobber axle. also, the oem axles have a lot more paint on the shaft, so more to chip off before you get to exposed steel and corrosion. finally, the jobber axles fit the cv boot around the outer cv, while the oem axles have a step ring that necks down the outer cv so that the boot smaller - less movement, less to wear, longer life.
