Just noticed this today. Is this an age thing or was there something that broke the seal?
I had an alignment done this morning on one of those hawk eye machines. I noticed the plates that the tires sat on moved in like they were under tension pulling out when they were unlocked.
Maybe could those plates have pulled outwards when they were locked in place and broke the seal?

If you had a shop do the alignment, I'd be calling them. Sounds like they did something wrong. If you did the alignment yourself, then that last part is irrelevant. Maybe someone with more knowledge can chime in about axle seals, but that definitely is not normal. Looks like the seal is bad to me

Certainly looks like a bad seal but I think it's probably a coincidence that it happened at the same time as your alignment. I can't imagine how an alignment would tweak your inner seal unless they broke the axle shaft somehow.

That's not a seal you're looking at, the front axle isn't sealed at the outside of the axle tube. That is just a plastic barrier that serves to keep rocks & debris out of the axle tube. The front axle is only sealed inside the differential so lube doesn't make its way down the axle tube.

Regardless, the alignment rack plates only serve to allow the front tires to be steered left/right & wouldn't break the inner seal. Those drops on the tire could be from nearly anything, the seal inside the differential pumpkin wasn't damaged by the alignment process.

That's what I was trying to say...doubt the alignment broke the inner seal. If you look at post one though, you can see a large pool of gear oil on the inner C, so I would still think the inner seal is the culprit.

I know that's a little plastic piece...it's loose, doesn't do anything for sealing. It is coming from the axle and has pooled in the part of the knuckle there, then overflowed down the tire. That's all the same stuff, same freshness.
