I got my Riddler covers all painted and got my new gear oil ready to go.

Before I swap these babys, I had the thought that the Riddler diff covers are larger than the stock ones. So when I put new gear oil in, do I need to put in more than the factory recommended volume? If so how do I tell what the new capacity should be? I thought about making myself a makeshift dip stick and jamming it to the bottom of the diff and recording the fluid level on the stock diff, then using that as a guide for the new level but wondered if anyone had a better method or could tell me if I am just over thinking it?

 

I believe its very slightly less than stock. Proper level for diff fluid and 1/2 way up the axle tube. I use a small zip tie.

 

I used the amounts listed in the manual for my D30 and D44. None came out of the breather.

They definitely do not increase the amount.

 

Yes, it will make a difference but it now takes more fluid than stock not less. look at the depth difference when you take the covers off the Ridler one is deeper.

That's incorrect. Because the cover is bigger does not mean it requires more fluid.

Use the amounts listed in the manual.

 

OK.....run low on fluid if you want not my jeep so I give a $hit.....

But it does have a larger capacity and to get the fluid to proper level you need to put in more fluid than the stock covers. Look here>>>>>>

Your response in that thread which is asking how much fluid to put in the diff.

Have you changed your way of thinking since then? I'm being sincere because I did a lot of the same searching when installing my Riddlers and I came up with the stock fluid levels. Even WOL's write up is using 2 quarts on the SOLID covers which are also larger than stock.

 

Read a few posts down from that one....I was posting the stock amounts but yes I still believe the riddlers take a little more. The fluid level should be about 1/2 way up the axel tubes. The inner workings of the gears rely on the level being up at a certain level for proper lubrication. If you get them too full you will see them puke but if you have them too low you will not know until you have pre-mature gear wear. In that post it says factory level for the front is 3. something depending the type of axel you have D44, D30 etc but with the Riddlers it was recomended to go to 4.0 pints.

I would rather put in a little too much and have it puke for a day or so than have too little and wear out my gears.

 

Cool, half way up the tubes! Thanks Everyone! About 4 pints for the front D30. Any idea about the Rear D44 with Limited Slip? Also, where is the best place to get the friction modifier for the LS? That's the only thing I still need to find.

 

Just did the front. It took just under 4 pints to fill halfway up the tubes just like you guys said. Here are the pre-install pics. When I get the rear done I will post some after install pics.
