Axle Seal Leak Question

I had a leak and took my Sahara (auto transmission) to 4Wheel Parts.


They put in a new seal into the differential. Next day I look and it was still leaking a little bit.


There was probably two weeks of driving between when I noticed the leak and when I had it repaired.


I called 4Wheel to let them know it was still leaking.


They said I could have potentially bent my axel due to heat from lack of diff. fluid because of the leak.


Does this sound correct ? Just wondering if they may have done something wrong or if I indeed bent an axel. Would they not have checked my axel from the start ?

Axles don't generally bend due to heat.

Unlikely you bent the axles due to heat. If you generated that much heat you would think the carrier and axle bearings would be toast.

I had to replace all the seals on my stock axle within 30k miles. Dealership warrantied the work but obviously something wasn't right. I started poking around and found my front axle breather was clogged with mud. Replaced and relocated all three breathers (both axles and TC) and haven't had a problem since.

This might not be your issue but it's a good thing to check.

That doesn't sound right at all. A lack of gear oil is not going to bend an axle, it will tear up the ring, pinion and spider gears and possibly the carrier bearings before the axle bends.

Which axle? if it was a front, they probably nicked the seal reinstalling the axle. That happens all too frequently (yes, I know this as a fact).

Did they damage the seal damage the seal when they put the axle back in?

Could be left over oil in the tube if they didn't clean it out properly before replacing seal.
