Default Bad vibration 80-110mph

Got a bad vibration coming from the rear of my car the other day from like 80mph-110mph at least that is where I let off. I pulled my driveshaft and saw that two of the weights on the transmission side were missing. I brought it to a driveshaft shop today and they said that the weights missing is not the problem. I checked my rear and the backlash is good and no slack in my u-joints. Pulled the cover off my rear and everything looks fine, no metal shavings or anything. What do you guys think it is?

Well I'm gonna have to disagree about the weights on the shaft. They can cause vibrations if missing. You can also check your rear wheels to make sure your not missing any wheel weights and check your pinion angle as well unless your running the stock T/A.

An unbalanced DS can cause all kinds of havoc at higher speeds.
