What's the Best Way to determine if your Drive shaft is off balance?

 

Well your question isn't really valid or informative.....

What symptoms are you experiencing to believe that your driveshaft is off balance?

 

some vibration as i accelerate. at like 50-60 mph

 

try to tighten the bolts in the back first. Sometimes over the years or many years those 4 bolts in the back tend to get lose and at a certain speed there is a vibratation from the drive shaft.

 

One bolt is missing back there. Does it have to be a certain weight to keep the right balance?

 

The driveshaft is a balanced assembly. While one bolt won't cause a massive vibration, it will cause some vibration.

Driveshaft vibrations are fairly obvious. They may come and go at various speeds but can be felt through the entire car, not just the steering wheel. The dash and everything attached to it will vibrate, and there may be a squealing noise.

Under the car, try prying on the driveshaft with a pry bar or big screwdriver. If it shifts back and forth, the u-joints are bad. You can also visually inspect the u-joints and see if they are broken.

 

Yeah, that would do it.

 

Since you are local Tucson, why dont you just bring it by my house and I will GIVE you the bolt you need before you kill yourself.
