Yep, keep a few of em around (1.80 audi ea) for those times when... The adj
is no big deal and requires just wheel removal.... I found that the trick is
to get the allen bolt to go back where the circle is on the mounting tab,
regardless of the wipers... The abs does a continuous ck of the system and
it defaults to deactivated if there is any sensor problem..... Any shop that
plays with the bearings/hubs/struts and the abs lite comes on, shouldn't
freak, and a cheap fix....
