Do them both now. I figured mine would just be the stator side, but when i pulled them both out, they were dry and cracking.
Its a pain in th azz to pull them out. Just let us know when you get to that point, as some of us have experience in it I:I
I will never do this again lol. I am not one to be doing work like this. I totally jacked my quad up. I pulled the old seal out, got the new one in (or so I think) an got everything put back together...added some fluid and decided I best check the kicker...NO PRESSURE...so I took the cover off again, finally got everything lined up for the kicker..once again got everything back on, added some more fluid...started it up, smoked like crazy (maybe even worse than before) and also NO CLUTCH...what in the world did I do!!!!
