Has anyone DIY'd either or both of these? I was just going to do the seals, but figured while I'm in there I might as well do the rattle repair kit as well. Both look relatively easy, just time consuming. Is it really as easy as it looks in the Beisan DIY? I'm going to do it in the next couple weeks, just want to see if there's anything I should know before hand? Any issues or problem areas I should know to look out for? And if there's anything else I should replace (other than the VCG) while I'm in there?
