Rear-end seal?

any part store that sells the seal should be able to get it. also get some red lock tight and put that on the yoke before putting on the speedie sleve it will help in the installation and will hep fill the grove after the sleve is installed over it and it wont leak thru sleve where it meets the yoke please consult a book on pinion nut tightness. some have a rolling torque to set the pre load on pinion bearing witch is crusual and get a new crush sleve do not use the old one it has alredy been crushed so it is junk
