(STICKIE) ST1100/ST1300 Wheel Bearing R&R Tools
This is a fabulous kit complete with written and video instructions, and the tools to make the job easy. I used for rear wheel bearings (not flange) on ST1300. I had purchased a "blind bearing removal" tool kit from Harbor Freight that looked like it should work - with a slide hammer to yank the bearing(s) out. Didn't work, no matter how hard I worked. Thankfully, they took it back for refund.
This kit makes it easy - knocking bearings out with a drift. Mine took some pretty hard whacks, but out it came - rust and all (no wonder it was so hard to remove). New bearings went straight from freezer into wheel with the help of the driver in the kit. My reminder to next person using it is: as you drive 2nd bearing, stop frequently to check the distance collar - once bearing just touches collar, STOP. It's easy to go too far, and restrict the bearings' movement. But if it doesn't touch, torquing the axle nut may well deform bearing as it tightens, making it too tight after you've reinstalled wheel (not a job you would choose to repeat).
All in all a successful job, thanks to this kit - SUPER - I can't recommend it more highly!
