Problem Reports

My XC90 experienced the exact same issue, though the leakage was minor when I caught it in time. As with many other like-units, the seals within the angle gear drive assembly began to fail, allowing for a slow weeping of oil out of its gearbox. to remedy the problem, I had a certified Volvo mechanic change out the seals with new ones. Unfortunately, those began leaking right away, so I had them replaced again (at no charge) with great success. The AWD systems on these cars are prone to such anomalies, so best to keep an eye on yours and have it repaired as soon as you spot the problem so it doesn't lead to a more serious failure later. Some common signs that system failure is coming is hearing a rattling, or fluttering noise coming from the angle drive or front axle assemblies (which tie into the angle drive box where these seals are located). Some owners have also reported a sound akin to that made by baseball cards clipped onto the front spokes of a kids' bicycle with clothes pins, or a sound like marbles rolling around in a barrel. Those sounds are common for an AWD system that is failing and needs attention, and can occur as a result of those leaking seals, or from a failure of the CV joints / axle assembly, or even from cracked boots on the CV joint that have let all the grease out causing joint failure. Short answer, best to have that whole system checked over by a certified Volvo mechanic whenever an oil leak is discovered in this area. An early catch can save a lot of grief later.

I had an oil leak and had it fixed now have another one.!
