Suspension issues.

When accelerating anymore then lik 15% I feel a vibration comin from the left wheel upfront. It only does it time to time. Sometime when cruising and I hit a dip and the car bounces slowly up and down I feel the vibration come back as the car goes up and go away as it goes down. Also I now notived excessive tire on both front tires...the left more then right. Another problem at highers speeds 60+ the car seems to drift side to side like steer by itself almost without me touching it and its kinda like the cars gonna lose control. The I took off the wheel to check things out I noticed the bushing on the upper control arm is like blown out and alost disintegrated. As for everything else it looked good. I check the bottom arm the joints, axles, boots, the rest of the suspension parts that seemed to be the only thing found wrong. I was going to replace the upper control tomorro or so. Although the alignment isnt off the car drives pretty much straight when I let go of the wheel. Just over certain speeds it feels like Im going to lose control. I was wondering anything else I should do to check things? Any help is appreciated.

IT SOUNDS LIKE WORN OUT SHOCKS MIGHT BE TO BLAME FOR THE BOUNCING & VIBRATION AS FOR THE DRIFT FEELING :dunno:

The shocks are newer maybe a year old at max. After struts of some kind and I got front coilovers. The vibration im pretty sure is the upper control around.. I also looked at it closely to notice my toe is off a lot. Thats what it causin the tire wear.. I hope thats the drift feelin too.

Replace the control arms and go from there. Toe in/out will cause a drift. If your car is lowered and never aligned after, of course the toe will be off, along with the camber too.
