its not the elignment car goes strait as an arrow. But when I go 80mph or more the stick rattles and the car (((((vibrates))))) if this is the drive shaft how much is it to get it ballanced and where is a reputable place to get that done or can I do it myself?

First, check to make sure your bolts are tight at the driveshaft. Then check your u-joints. Also, make sure your tranny mount isn't on it's way out..most are bad after only a few years. I'd bet it's one of those..and not a driveshaft needing to be balanced.

Drive Line Service of San Leandro (510)352-3500 charges $65 to get a stock 5.0 D/S rebalanced..It happened after the gear swap, right?.....
Try going around 170mph and let me know if it still vibrates.....JK [ January 30, 2003, 11:43 AM: Message edited by: Black94 5.0 ]

my car does the same thing right now but more like at 70mph + i went to look under my car and found that the u-joints behind the tail shaft of my t-5 are not u-joints any more there more like just studs holding my driveshaft on. i'm just gonna save and get a fms alum drive shaft i havent heard any real complaints about the alum driveshaft.at least on a mildly moded fox body.

Yeah it was after I got the 355's installed. It would do it before but at around 100mph and up. Now with the 355's is around 75 - 80 mph and up.

most of the time its the just the driveshaft or tranny mount... if it is the driveshaft, just buy a new aluminum one from fms. when i changed my u-joints with quality pieces, it got worse. in my case, i'm still trying to find the problem. i think its the tailbushing in the transmission.
