[s-cars] I'm finally studly... (long)

Wed Jun 25 20:52:42 EDT 2003

Well, ....
Where to start.
Personally I don't find it a problem to hoist a wheel up and put it on the
hub and line everything up.
Either on the floor jack or hoist doesn't matter. I can see some advantages
to studs, but not what this is all made out to be.
I have never had a bolt that I haven't been able to remove, but I have had
many a stud (GM typically) that spun with-in the hub.
Now that sucks. It is a tragic waste of time farting around with a spun
stud. Has even cost me a steel rim many moons ago.
So, I will keep my bolts. I will also ** Antisieze** some rims. There I said
it...
Let the games begin :-)
