I had my car up on jack stands and was feeling around trying to find the fill plug to check the fluid level but couldn't. Where exactly is it on a Moser 9" (96 Z28)

 

Only place it could be, on the rear cover. standard location.

 

Yeah I know that, I'm a mechanic not an idiot. I didn't have enough clearance on the jack stands to see on top of the center section so I had to feel around blindly and could not find the plug for the life of me lol, I don't know I guess I'll give it another try.

 

dude it may not have one. sounds retarded but my moser 9" doesn't. got it off a guy and if i need to fill it then the center chunk has to come out.

 

I thought that might be the issue. That sucks owell, I'll tap one out when I get a chance.

 

yeah it sucks i did a ton of work makin the housing lik new said i need to make a fill bung and i fillled the rear put it together and in the car without ever doin it im kinda slow

 

check on the slug casing on the front side.

 

There should be a plug in the center section. If it's a standard Ford 9" center, look on the passenger side, above the reinforcement web. If it's a Moser center section, look to the front, above the pinion yoke, off-center towards the passenger side.

 

Moser charged me $100 extra for the fill cap...lol what a racket. It is opposite the third member on the right rear...silver cap..You would have seen it. It sounds ridiculous but you dont have one. The thing also holds 4 quarts of CONVENTIONAL ONLY gear oil. I guess they expect rear end removal for refilling if you dont pony up for the fill cap initially.

 

That's a Moser hoser job! But once you have to take stuff apart to change the oil, $100 probably would have seemed like a good investment. I guess the thing to do is make provisions for a drain/fill in the housing center before putting it all together in the first place.
