Do I need to get new gaskets? I know some can be reused like my other car but is it that way on the dodge. Im going to be doing front and rear. Also what type gear oil is the best. Thanks

 

I used mobli 1 synthetic. The gaskets are reuseable. Just wipe them down and put them back on.

 

Royal Purple is in mine. About 8 bucks a quart

 

Ok so how many quarts does each one take?

 

The rear is almost 4 and the front 3 quarts. I also went with 75w 140 as that was what the dealer told me they were doing on all that came in for changes.

 

thanks. I also remember someone on here talking about the bolts breaking off? Should I buy a few spares before? What is the torque? I think it was 25

 

I guess i was lucky, no problems with any of mine. Cant remember the exact torque specs but that sounds about right. I also used a little bit of thread locker as there was some on there from the factory.

 

No problem with the fastners on mine either. I think the recommended torque was 30 or 35ft/lbs. I torqued it to 25 because I was scared of the bolts breaking. Put 75-90 in mine and yes the gaskets are reusable

 

Yes be careful when you torque the bolts back down, the alloy they are made out of is junk. It doesn't take a whole lot to twist them in half. I had to use easy-outs to remove mine when I broke a couple of them off. I couldn't believe how easy they broke.

 

Thanks for all the help. It was 4 in the rear and 3 in the front. Also I drained all the fluid from the fill ports on the front and rear diff. I know a friend at a dodge dealer and he says when they change the customers front and rear they dont take off the cover. They use a pump and pump it out so thats why they never have broken diff bolts. I did the same and measured how much came out.

 

I always pull the diff covers. Yes it takes extra time to take out 16 bolts rear and 14 front, but I want to see the gears and also to get all of the old oil out of it. I just did mine and the rear took 4.55 qt's & 3 front.

 

What pump did you use?

 

I hand pimp i bought from home depot. It was like 10 dollars or something like that,

 

Does anyone know for sure what size bolt they are?

Figure I'll order up some from McMaster Carr in a good stainless.
