I just changed my seals over the weekend and was running through my head wtf i could use to pound in these seals. I seen in another thread someone used pvc pipe and had to dremel off a good portion of it to make it work. If you are changing your seals go to your local auto parts store and get i believe it was either 18 or 24 inch exhaust pipe. 1 7/8inch and it will do the trick. Just pound it in with a rubber malet. Just an fyi i figured i would share if anyone was thinking about this diy...
