I recently got ahold of an aluminum LS1 driveshaft for free...and i had it put on my car..94 Z28...It seems fine..but I've just started dripping tranny fluid and there's a really annoying loud rattle under the car that sounds like it's coming from the front of the driveshaft. Should i put the LT1 stocker back on?
Thanx guys

Seems like something new goes wrong with this pile every other day.

 

The DS works on our cars with no problems. Perhaps they fubard something when they put it in. Get under there & take a look
