1991 Chevy Astro 2wd vibration above 50mph
I have balanced all 4 wheels and checked front end and nothing is loose. Also there is no
movement on the drive shaft. What is going on?
If you can, change out the tires and see if this stops the vibration above 50- MPH. I replaced the low mileage tires on my Corvette that were 11 years old and it stopped the vibration above 65 MPH. I was told the tread was starting to let lose inside the tire itself. I had the tires balanced three times and even changed tires with rims to no avail. New tires and the vibration is gone. No vibrations up to 135. It handles a ton better. Check wheel bearings also and the idler arm.
