I just went to change my rear end fluid for the first time since I bought my camaro and there is no fill hole. Am I missing it, or is there no fill hole. I found a plug on the front of the 10 bolt but there are no hex marks to take it off with my ratchet. Did GM make it so you have to drill a hole in the bolt cover? I've changed 9 in fords and 12 bolts, this is bugging me.

 

Should be on the passenger side.

 

I feel it, How do I take it off. I am used to taking off a bolt.

 

Now I feel like an idiot, just found the hex plug. I was looking at another plug that doesn't come off.

 

mine was on the passenger side and was a square drive, 3/8" IIRC

 

majority of the time on fords and chevys.

the fill plug is next to the pinion gear. and its almost always 3/8 drive.
use a 3/8 extension and a ratchet of course. and you get it out no prob
