TOM: In our experience, Subaru axle clamps do tend to seep grease.
RAY: Kind of like we do when we get home from work at night.
TOM: I don’t know why this happens on Subarus. It may be the unique angle created by their higher-mounted differentials that makes the CV boots hard to seal well against the CV joint housing.
RAY: But we’ve also noticed that the minor seepage usually does not lead to imminent, disastrous axle failure.
TOM: But without seeing your car, it’s impossible for us to know how badly yours are leaking. If it’s really minimal seepage, the dealer may be right.
RAY: On the other hand, if it looks like grease has been slung all over the place, like after my brother tries to make lunch, that indicates a more serious leak, and then the answer to your question is yes, that could eventually lead to costly repairs when your CV joints fail.
TOM: The problem is, do you trust a couple of oil-change guys who might not be Subaru experts or a Subaru dealer who may have an interest in not fixing your car for free.
RAY: So my recommendation is to find an independent repair shop that specializes in Subarus, and ask them to take a look and tell you what they think you should do. That will give you peace of mind.
