Also, these past 2 weeks or so I've been having issues with my starter. Sometimes it does nothing when I press start other times it starts right up. Not sure if this is related.

 

100% propshaft bolt.

 

Those that said it prop shaft bolt are correct. Not only did one fall out, but one was about halfway out and another one is completely gone. I retightened the five and ordered another one.

Can anyone with a manual mind checking what the proper torque to use for those guys. Though not sure how I can torque it as all I could fit was an L type allen wrench.

Again, thanks everyone for the help. Pointed me straight to the problem.

 

They should be torqued to 24 lbf-ft and the manual also says to replace them, not sure how important that is though.

 

Thanks for checking

 

No problem, as for reaching them with a torque wrench you should get a set of those ball head allen sockets.
These might be a bit long but you get the idea http://www.harborfreight.com/7-pc-38...set-67888.html
