i will agree with getting the drive shaft balanced. i had when i did my CJ's shafts..made a world of difference. I was told by the shop that balanced mine to make sure the u-joints i was going to run was in the shafts so the balancing would work

 

Well I spoke with Troy at Tom Woods yesterday and explained the problem. He made me do a test: drive 75 mph until it is vibrating and shift into nuetral to see if that stop the vibration. If it stops, it is not the shaft. It didn't though. I must say that they offer great service. Troy was extremely helpful and knowledgeable and after talking to Tom, they decided that they will send me a new one that I can install next weekend after which I can send the first one back. He even said they will include the shipping label for the return. That is awesome service if you ask me! Obviously it would have been better if it had been balanced correctly the first time, but I heard it is a common problem when you get a new driveshaft on a vehicle.

I will let you know what happens after the second one is installed!

 

I had to do the same thing. The new one they sent me was vibration free and didn't cost me a thing... Though I have, and have heard of problems with the balancing I still think Tom Woods is the way to go.

 

Tom Woods IS the way to go. I don't get why they don't just take the time to balance the shafts good. Its costing them money for the shipping.
