especially at high speeds, like 55 plus, it sounds like my wheel or wheels are wobbling, i keep checking them to make sure theyre not flat that it sounds so bad. could this be because of my saggy front springs making the sound..? anyone else have this problem .....??

 

Does your steering wheel shake also? If it is check out the post (Shaking Steering Wheel) there are a number of things than can cause what you are describing.

 

Saggy springs are not a likely culprit. Is it worse under load? Will it do it in 4th and 5th gear?

 

yes, it does it in 4th and 5th gear.
