I was redoing my rear shaft and the bolt and washer that holds that shaft to the output shaft on the engine side is broken off inside. Im gonna drill and use an easy out for that. Everything going well there.

Because of that i took a look at the front shaft. I was able to just pull it right off by hand no tools. I discovered that the bolt that holds the front shaft to the engine is missing. Its not broken off inside, just entirely absent.

I bought my bike used a week ago so i ordered the bolt to fix the font too before the play causes damage to the front.

My question is this. I had the bike in 2×4 when i took it apart and didnt realise that i would be able to pull the front shaft off so easily. The service manual says to make sure the bike is in 4×4 when u remove the front shaft. That ship has sailed. How is this going to affect me when i reassemble? What precautions should i take?
