Worn shocks and/or struts will cause cupped tires. There may be another suspension or chassis component worn, but the shocks/struts are the first components that should be inspected.
It will be easier if you pull off the front tires then you have the shock bolts at your reach. It took me 30 min for both front shocks.
maybe your tires are too hard
You can pump some shocks, but not all.
check your tires first- one could be bad then your suspension- shocks check your tires first- one could be bad then your suspension-
Bad shocks, ball joints bad, tires out of balance. More then likely shocks.
Out of alignment or bad shocks or struts
Bad shocks. Your springs buffer car movement, but your shocks dampen spring action. If not for shocks, the springs would allow the tires to bounce and leave the ground (or dribble).
I would think its the shocks causing the vibration or the car to wobble, do check on car shocks!!
Not hard at all. For the rear shocks just crawl under the vehicle, unbolt the shock from the top and bottom, pull it out, and replace it. For the front it's about the same, only difference is that you'll have to jack it up and remove the tires to get to them.
Bad shocks, worn front end parts.
Well I think you should change your tires to triangular blocks of wood and see how that goes.
