After reading all the posts recommending NOT to try and rebuild or take apart a Freewheel, I decided to do it anyway. Well, I completly rebuilt my Suntour (Perfect) Freewheel and it works beautifuly. I have no idea what all the fuss is about in regards to taking one apart? I took mine apart and replaced the Pawls, Spring Pins, Springs, and Bearings. Lubed everthing with Super Lube (with Teflon) and reassembled it with zero issues. I now have a like new Freewheel and enjoyed the rebuild. If you have been thinking of rebuilding your freewheel and have hesitated due to everyone saying it's too difficult go for it! It is easy and you end up with a great (like new) Freewheel.
