    stud bolts bottom of forks

    Anyone know how difficult it is to remove the threaded studs on the bottom of the forks. PO stripped one and I need to replace. See pic attached. Punch is pointing to it. This is the good one.

    Better to show the bad one! But I'd say, "oh-oh! " I've always had to drill these out...(and too many times wish I hadn't tried....) I'd consider taking it to a machinist .

      They're held in with factory thread locker and come out pretty easily if you hear them up first.

        There you go! A decent picture would,ve been nice...Mr.Sunny and Mr.Darkness ! I assume the worst with snapped off stud on corroded barn bike but if just the threads are stripped...still, Mr.Darkness can still see you breaking it off with a pair of vice grips...tiny turns in-out as you try to turn it out...

          I've replaced a couple of those with no issues. Bunch of spray before hand and a pair of vice grips if I remember right. There might have been a bit of heat to one of them but never had any real issues getting them out.

            I haven't found them to hard to get out either.Like Rob said a vice grip usually suffices.My GPz fork is wearing one taken off a GS fork.

              Yep. Common job, since Suzuki made the studs out of cheddar cheese.

              A little heat helps -- no need to get it red hot or anything -- then grab 'em with locking pliers and twist 'em out. You can get 8mm studs at a decent auto or hardware store. (Notice I said "decent" -- the teenagers and drifters running the register at the big box stores won't have the slightest idea what you're looking for.)

                Thanks to all. I let it sit for a few days with PJ Blast penetrating oil on it and it came out just fine. Local auto shop had a 8mm stud. All is good. Thanks again.
