Just installed 4 new kybs in my 05 legacy sedan and now have a shimmy/vibration when going over 60. Could it need an alingment,It didn't have shimmy before. I made sure to mark the camber bolt and put back in orignal position.Could the new struts make the worn components be more felt ie balljoints/tierods/bushings. Thanks

Usually a shimmy over 60 is a wheel balance issue, and yes it can just happen. Does it go away at 70-75?

 

Rotate the tires to see if it moves.

Can also be sway bar links.

Agreed with Nipper, usually a tire balance/tire pressure issue. Loose inner tie rod ends will make themselves evident at that speed also.

Problem finally fixed.Front drivers side wheel bearing bit the dust.Now drives like new.
