Can anyone answer this question? When im driving and get to 70mph + my steering wheel starts to shake, know why that is?

Have you had your suspension looked at recently? It could also be that your alignment is off. Several different things can cause this to happen.

spppeeeeeddddd wobble. haha. i'd go with mike on this one. because i have no experience with suspension. but if mike wants to list each part that is in suspension and what it does i'd love it, i'd liike to know! all i know are Struts and Air Suspension..... i dont know what struts do though. Air suspension i know, it works on my friends stang!

GL.

have you been maintaning a constant tire pressure and rotating your tires every 6 thousand miles? is your allignment in need of adjustment? have you possibly bent the rim of your wheels?

not sure if my rim is bent or not, i did have a blowout a couple months ago, but it wasnt bad. when i got a new tire the mechanic said i needed new struts.?

this is typical problem(had it many times) when ballance is out, ballance your front wheels, or all of them. if doesn't help wheell alignment needed. imo
