I had my oil changed about a week ago on my 2016 Forester with ~45K miles. The tech toped off all the fluids and all that and said that the rear differential was leaking and that I should get it into a shop sooner rather than later. I haven't been underneath, but there doesn't seem to be any evidence of a leak on my driveway. Similarly, no weird noises or anything. Could the tech have been mistaken? Is this a better-safe-than-sorry kind of thing where i should bring it in anyway?
Not sure if this would be relevant or not, but ~5,000 miles ago, the car was hit from the back driver side while parked. The damage was mostly cosmetic with the exception of rear suspension and exhaust.
Any thoughts, wisdom or insight would be greatly appreciated.
even if there are no drops on the ground under it, there may be evidence on the axle itself- gotcha. That pretty much answers my question of whether or not it warrants a trip to the mechanic. Thanks!
