Need Help S-10 4x4

I need some help troubleshooting a vibration in my 2002 S-10 4x4. I took it in for a wheel alignment. The shop said it needed Balljoints first ($800). I decided to change the balljoints myself. I also replaced the CV Axels. O'Reilly's Auto Parts sold me 3 remanufactured Cv axels that where no good. They finaly gave me a brand new CV Axel. The 4th axel cured most of the vibration. I also put new wheel bearings in the truck. Now the truck vibrates at different times and different speeds. Sometimes it doesn't vibrate at all. Does anyone out there now what is causing this? dropmaster2@hotmail.com<!-- START CLTAGS -->

You're driveshaft &nbsp;pinion angle might be off.

I checked the U-Joints in the drive shaft. I have had this truck jacked up for a while now. Maybe 8 months. It was running fine untli I changed the balljoint, wheel bearing and the 4 cv axels from O'Junk.&nbsp;&nbsp;I noticed when I turn to the left. it seems like the vibration get worse on the left side.&nbsp;&nbsp;I am pretty sure the pinion angel is ok.

you might have lost some wheel weights from the past vibrations, might wanna have your wheels and tires rebalanced

I was hoping it was that easy. I had the wheels off alot. I thought I might have knocked some weights off while removing the wheels. I haven't had the rebalanced yet, but I am gonna try that tomorrow. All the weights apear to be there.
