About a week ago I hopped my Z's front bumper up onto a parking curb, since then I noticed a slight vibration in the car, more the body and not the steering column. Over the next week the vibrations got considerably worse till if I went over 20MPH it felt like my brain was going too rattle out of my head. You should also know(not sure if related) that when I go extremely slow I hear a scraping sound internally(not against the ground). Anyway, I got too my friends shop and had a mechanic hop in, shifted into first gear and the ****ing driveshaft snapped in half. It all started after I hopped the bumper onto the parking curb and I was curious if you could tell me how exactly that led too it, if the internal scraping sound had too do with the driveshaft, and if I should be concerned about anything else like the tranny, axles or differential. Haven't had it put onto the lift yet but I will shortly(obviously this will shed some light onto the situation and if there are any other issues) but in the meantime I was curious about your inputs and if you can shed some light on this BS. THANK YOU

 

Also is their anything else I should buy when purchasing the new driveshaft or is their a specific place that is best too purchase the OEM driveshaft from?

 

Check the FS threads I think I saw a few driveshafts on there unless you want a brand new one could save your wallet.

 

The OEM drive shaft is carbon fiber...pretty sweet if you ask me...when you jumped the curb I bet you shoved the exhaust into the shaft and it probably chipped or knicked it. Essentially you've created a weak spot on the drive shaft and it perpetually got worse. I broke mine back in the day in a similar manner during a launch...





I would either find one on the forum or a local salvage yard. Either get a good amount of pictures or be able to inspect it in person - you don't want any surface damage. If you do want a new/aftermarket driveshaft look into the drive shaft shop.
