I know it seems like a lot of taking apart but just cause somebody says they just rebuilt the top end with all new gaskets and seals everythings good to go.. Technically that don't mean **** cause what if they didn't do it right? Didn't put the bearings in correct or what if the inserts are super worn, gasket areas are all tore up? What i'm sayin is ya never know whats on the inside!! Gotta open her up to see for yourself!! Shop manual will help a ton and take pics with your phone to help put back together!! Also zip lock baggies and a marker help a ton!! Label everything in regards to the manual on your baggies!! Also ask for help if you can and if you need quick response just pm me. I get the response to my phone.
