story (not important, but the bold part might be helpful in identifying the bolt):

it definitely looks like it could be part of my truck, but I couldn't find anything missing.. help would be GREATLY appreciated

a few pics here: what is this for? - Imgur
it's about 1.75" long.

THANK YOU FOR READING

 

Ill have to go out and check but that really looks like the crank pulley bolt, what size socket fits on it?

 

Indeed that is the bolt that holds the harmonic balancer on the front of the engine.

 

as soon as i seen it i was thinking cam sprocket bolt, but would be difficult to jump outta the engine lol

 

cam bolt is just a normal long bolt, Im in the middle of a new timing chain

 

wow, thanks for the quick responses everyone.
oldschool64bus and White Trash are right, it was that bolt.. wow.
I guess whatever felt like wheel hopping was caused by something else? lol sigh

would threadlocker help keep this bolt in? not sure how much stress this bolt receives. thought I got it in really tight last time..

thanks again!!

 

You don't need thread locker.thread it in and whack your ratchet with a hammer a couple times to tighten it down and it should be good.

 

done and done. thanks. hopefully it'll stay in!
