i've got a front driveshaft that was siezed up from being compressed all the way. tried to pull it apart and it wouldn't budge so i ended up chaining it to a tree and hooking the winch onto the other end. it finally popped and flew apart. upon first inspection the splines looked fine and it was smooth until the last third of compression. i discovered that there is a blue teflon/plastic like sleeve that goes between the splines of the shaft and yoke and it had worn out and jammed/ bunched up at the end, causing the seizure. anyone know if that is a replaceable part? i finally got the ruined one out but now the joint has slop in it because of the gap where the sleeve used to be... i'd like to replace the sleeve instead of a whole new shaft since i recently put new u-joints and cv/ centering joint into this one.
Thanks!
