my cav shakes around 65 please help

Have you had an accident lately, bumped a curb to hard. Shakes could be a lot of things but if none of the above applies to you I would look for a tire that has a slipped belt. You could have also lost a wheel weight. Take it to a tire shop and have them do a spin balance on your wheels just to be safe. You may also want to inspect your halfshaft for a worn out ujoint.

Hope this helps Let us know.

Welcome to AF:)

you probably just need your wheels balanced.
