Big Thanks to EDDIE510 for installing the aluminum driveshaft.. Those bolts were a b*tch ahaha but you did it bro!!

Well so, aluminum driveshaft was a pretty simple bolt on and after the install now on over 100mph on freeway the car starts to vibrate terribly!! What do you guys think can cause this? Aluminum Driveshaft Balancing??

Thanks Guys for the help..

needs to be balanced!

Posted by mike g (Member # 2919) on :

what kind of aluminum driveshaft is it? my ford one doesn't even vibrate doing 140.

So yeah probly needs to be balanced.

Posted by Bill/APEX Motorsports (Member # 636) on :

If it didn't vibrate before, and all you did was install the driveshaft, then yeah, check the balance. Any driveline place can check the balance, but not all of them can balance an aluminum shaft. If they offer it, opt for the high-speed balance.

Rotate the driveshaft 180 degrees from where it is now and try it again. Ford uses yellow paint marks on the pinion yoke and rear of the factory driveshaft to match the balance, so when you swap to a new shaft, you might have to try to "clock" the driveshaft up to 4 times to get the best balance.

CHopefully you guys put threar locker on the bolts or they can back out. But i Know Eddie Knows that. [Big Grin]

Posted by ScottRF88 (Member # 7882) on :

Yep I had this problem found out it was the bolts backing out. Tossed that drive shaft into the pavement.

Does it always viberate at the same speed or does it come and go? if it's not always the same should check the bolts make sure they are all tight.

Seeing as how he did this almost 4 years ago I guess they stayed in. [Big Grin]

I only figured out how old it was when I saw some of the people that had posted in it before me.

I think you meant to say "Rotate 90 degrees, and you may need to do it three times." If at that point you stil have the vibration, (and didnt get busted for going over 100mph) get the balance checked.
