I found these two guys in the trunk with my spare tire when I originally bought my car (see attached poorly photographed, fuzzy image). Not sure what they do, but they both looked a bit corroded. Part #s on them were 62147 and 45313.
Also, I was never able to locate my wheel alignment tool (the long thin rod that you use to line up the wheels when tightening the lug bolts back on). Where can I find one of these? I've removed and remounted the wheels before with no trouble, but I'd like to be doing things the proper way.
