Every Used T.S.S. sled I've bought the Knuckles and steel bushing are almost frozen or completely locked up and pivoting on the bolts ! I've bought sleds that the locked up joints won't even allow the springs to return let, alone the struts to work when hitting a bump. The T.S.S sleds have always gotten a bad rap for slop developing when the ungreased steel bushing's freeze up they grind away on the nylon washers ! I have sleds that are 15+ years old that have never had a bushing kit and are almost as tight as new. Just take the knuckles apart every 2-3 years and the ski mount every year and grease !
