I have recently been having quite a bit of vibration during hard acceleration and right around 70 mph. The vibration is not so much in the steering wheel but able to be felt in my legs. It almost seems like the wheels are skipping when accelerating. I just had new inner and outer tie rods and sway bar endlinks installed because im slowly working on rebuilding my front end to try to get rid of the shake. I have a 98 s70 glt with 126,000. I was wondering if it sounds like a problem with the struts or possibly control arms? I have had my tires rotated and balanced and it was just aligned. Any ideas? Also, was wondering if it could be the rebuilt drivers side axle that i installed a couple of months ago. The volvo dealer told me that they have a lot of problems with rebuilt or aftermarket axles.
