so when i get to about 80+ my driveline vibrates bad...but sometimes it dosnt just now i was cruising back home on the 805 north doing 85+ the whole way and didnt notice hardley any vibration what so ever, so what can this be? can a new tranny mount or bushing change this or effect this? if i can just fix this effing vibration ill be happier than ever now. anyone gone through any trial and error?

and yes i know about the alum DS im working on getting one, or getting the orig DS re balanced, if this is an effective way to the solution also...

 

Try from a stop and give it gas. If you feel any vibration then it would be your tranny mount. It's an easy fix and the part to replace it are fairly cheap. Go with the polyurethane tranny mount.

 

like you said aluminum driveshaft balance wheels. not sure if a transmission mount will cause vibration like you are talking about tho.

 

are you saying put it in neutral and give it some gas? its only at high speeds and it does it bad sometimes, someitmes not.

well i want an alum DS but arent they like 800 dollars?? thats a good penny. how much does it cost to re-balance our stock ones? or is it even worth it? and im not worried about the wheel as of now, cuz i just ordered some chrome IROCS with wheels and should be here any day now....thanks for the input though guys.
