Hello,

I have a 99 s10 blazer zr2. It is shaking like crazy at about 115-120km. You can feel it start, very lightly around 60km, it doesn't get much different until I hit about 115, then it just goes off!

I have put new tires on, had them balanced. Both front bearings have been done in the last couple of years, though it almost sounds like one of them is going again, but there is no play in the front wheels. Lower balljoints just replaced today as they were extremely worn on the passenger side. Uppers still good. Still shaking.

U-joints appear good to visual inspection, driveshaft has no play (Do I have to raise the truck and un weight the read end to check this??) sorry Im a noob. Front drive shaft, appears ok to visual inspection.

I dont know where to go from here
