The reason a slight gap appears at the top on a correctly aligned of dollars at stake in machinery, the drive support system must Using the correct wrenches and sockets, attempt to further tighten the mounting bolts. A front-end alignment usually costs between $65 and $100 (some brands, of course, are more). Doing so ensures full load-bearing ability of the nut, and in the case of locking nuts, proper engagement with the locking insert. Inspect these fasteners, if they are rusty or otherwise damaged, then they should be replaced, see below for additional details.

Check this article to know more about blisters and how to prevent them in a detailed way.
