Report: Oil May Leak From AWD Differential Housing
Volvo XC90 Problem
Average Mileage: 91,285 mi (60,000 mi - 142,000 mi)
Oil leaks from the all-wheel drive differential housing have been reported.
first had to have seals replaced for an oil lead, a few months later another oil leak; had oil trap removed. Labor for this very expensive, first had to find the problem, so I paid that labor. Then they ordered the part and had to pay the labor for repair, nearly $1,000 in labor alone. Now, immediately after that repair, another oil leak. I am told it is probably head gasket and will cost approximately $4,200 including labor. Just can't do it.
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.
