I have a 2001 S60 2.4T. It's always had a slight vibration at 60+ MPH when accelerating. Let off the acceleration, and it goes away. It recently got worse and started vibration at lower speeds, accelerating or not. The dealer replaced the passenger side front axle for $546 parts and $98 labor. There is still a slight vibration but much better than before when it was barely noticeable. The dealer recommends replacing the driver side axle shaft.

Can I get this done cheaper? If I'm looking at right part online, I think I can get it for around $300?

 

The labor sounds OK but the part is way high. You should be able to get one for around $200 rebuilt.

 

I just looked it up on Ebay and those axles are seling starting at $80.
