As i browse the forum, i see someone is having an issue on his balljoint ,shim etc... well i had the same problem when i was installing my disc brakes, i tightented the dome with the lock tab (MINUS the shim) all the way down and it tightened perfectly. i asked someone and he said to put the shim,no matter what, so i put the shim then tightened all the way down, THEN it was loose. so my common sense told me that off course, without a shim it was tight all the way down , why would there be a need to put a shim?????? only to get loose?? NOW it's been almost a year and my balljoint is still tight and not loose, just perfect. I therefore conclude that : SHIMS comes with the kit but should NOT necessarily be used. it's just a back up in case there's a need. it's not a must to use it. it's not written in stones that it should always be used. some people even orders extra shims, i'm like really? but it it's a case to case basis. it's not that if you don't put shims you will get into an accident.. nope! it doesn't work that way.
..and i even read that one person even grind the bottom of his dome nut to accomodate the shims (????,,,,i'm like,, omgeeee!)
