Differential Question

Does anyone know of a dff fliud which seals internally? For example, the oil additives which stop leaks.

why would you need it to seal something that uses diff fluid? and I don't think most of those additives truly do much, maybe a temporary fix

Where is it leaking? I don't know of any additives like that. Even if there was I wouldn't recommend doing that. The best thing to do is fix the leak. Don't let your diffs leak all the fluid out. That would be costly.

Unfortunately, the diffs were fixed about a month ago. The mechanic told me that due to the amount of mileage that his work was not gaurenteed. SO the dumb ass I am, I had him do the work anyway. He repaired the pinion leaks (he said it was not leaking from the pumkins) front and back. The back held but the front is still leaking. I am looking for a quick fix instead of taking it to a different mechanic and going through the same mess. I do plan on fixing the diff leak soon when I can save some money to do so. Thanks ahead for your replies.

Not leaking too bad. Counted about 3 -5 drops on my driveway per day

That mechanic's excuse to not warranty his work due to the age of the axles was one of the more lame things I have ever read here. It isn't difficult to seal the axle tubes or pinion shafts in a Jeep axle, you just have to know what you're doing.

But to answer your question and knowing the types of seals our axles use, there is no aftermarket stop-leak product for them like there is for things like radiators or power steering pumps.
