Vibration/shuddering after half-shaft replacement
 

Hi,
I just had the front passenger side cv axle assembly replaced on my 1999 Mazda 626 LX.
As soon as I drove away from the mechanic's business I noticed a vibration/shuddering when I accelerated! Actually alot worse then the old bad axle that came out if you can believe that. The old axle had a boot that broke open and the joint went bad, and would clunk and grind when turning. Why would the new axle vibrate or shudder when accelerating?

Anyone ever had a front axle assembly replaced and encountered the same problem? I was thinking at first that maybe I ordered the wrong axle, but I rechecked just to make sure it was the right one and it is. I have a 2.0 4cyl. without abs.

I will be taking it back to the mechanic Monday morning to figure it out. It just bugs me that I spent money on a new part and labor cost only to have a problem still. Could the axle just not be aligned right or can it be adjusted some how? Anyone with any idea out there?

thanks a bunch...Lanny
