Hi im new here i have a 98 4x4 blazer and i noticed that when i have been driving it recently that it feels like the front left tire feels like it wiggles (dont know how to say it any better lol)left to right as i drive it and i just had the upper and lower ball joints replaced it seemed o go away for awhile but now two days later it feels the same again. i don know much about cars really lol so if some one could give me advice on it would be greatly appreciated

 

I would check the tire pressure, and maybe get it aligned to start with

 

more info would be better, is it just a vibration while driving (could need a balance, or out of round tire) is there play when the tire is off the ground (loose lugs, bad bearing, joints..)

I would start with maybe rotating the tires, if the vibration moves to the rear of the vehicle it is just a balance or out of round.

 

x2.

Rotate the tires and see if the vibration follows the tire. If it does, have the tires road force balanced (not the typical balance machine).
