Front Diff Leaking/Overfilled at the same time?
Swartlkk, thanks for the advice. I found the real source of the leak. It isn't coming from the center where the cable attaches to. It is coming from the lower bolt hole. I loosened the 3 bolts and found the gear oil coming out of the lowest bolt hole and dripping all over the place. I tried putting some RTV around the hole, but the oil wouldn't stay off long enough to put it on a clean surface before I put it back together. I called the auto parts store and they recommended liquid thread sealer or teflon tape or even JB Weld if I never plan on taking it off again (which I am not going to use). They also suggested rubber washers or O-Rings, but wouldn't that make the assembly crooked or leave an opening between the 2 assemblies? Any other way of sealing that bolt in, but making it so it can be removed and reassembled? I already have oil resistant RTV. Could I just put it all over the bolt? Thanks again for the tip.
EDIT: I tried putting RTV on the bolt. No luck, especially since it comes off once I put it back in. Maybe I should scrape it off and put some Permatex Thread Sealant with PTFE on there? Maybe High Temperature sealant?

Jack up the passenger side as high as you can leaving the driver side as low as you can. This should keep the diff lube away from the area you are working on. Then clean all of the surfaces really well with brake cleaner and allow them to try sufficiently before attempting to seal them up. I would use Loctite High Temp Thread Sealant on the bolts (all of them) and RTV on the faces. That should seal it up nicely. Don't let it down off the jacks until everything has properly cured.
Thanks for the tip. I will do the High Temp sealant, but I got another idea that might help seal it. RTV seems to thin for doing this without taking it apart, but what if I get some high temp epoxy putty, put a long and thin piece of it on the end of the bolt and then using the bolt, pack it in the hole to form a plug at the end of it and then take the bolt out to let it set for the 4 minutes and then put the bolt back in? I honestly cannot afford having someone pull the axle shaft off for a quarter size leak per night, but I would like to try less expensive means to stop it from dripping.
