Ok, so the problem Im having with my blazer is that the car begins vibrated when I reach 20km/h. At this speed the car starts to shake. This started happening randomly. The strangest thing is that it comes and goes. I also hear a pop sometimes when I turn combing from the back.

Thanks for any help.

 

Check the universals on your drive shaft for the pop. It could also lead to some vibration.

That popping could be bad u-joints on the drive shaft.
A kid I know did that the other day on his 96 Blazer, and no mo' poppin'.

 

Thanks for the help, I replaced the u joint connecting to the rear differential and it fixed the problem.

 

Good Deal
