We operate a Hyundai authorized service department at Happy Hyundai in Oak Lawn, IL offering a rear differential service that your vehicle will eventually need. No matter if you need an inspection due to troubling symptoms of a defective differential, gear oil change, bearing repair, or total replacement service, rest assured that our certified technicians know your rear differential and its services professionally. We will only install the highest quality genuine Hyundai OEM parts and synthetic gear oil.
The rear differential sends drive power into the rear wheels while adjusting for the difference in rotation as your Hyundai corners. Most drivers do not even consider how important this part is for driving comfort and safety. The differential has internal gears and bearings bathed in a lubricating gear oil that can break down over time. This means that every so often, your Hyundai will need to replace the old gear oil with fresh oil. Without changing the internal oil, you could experience damage to the gears, rings, and pinion. If we find that a rear differential is damaged, a gear oil change will not fix the problem, and it will need to be replaced.
Hyundai recommends that the rear differential oil gets inspected and serviced every 30,000 miles. However, if you notice any of the warning signs of a faulty differential, it is wise to have it inspected and serviced promptly no matter what the mileage.
If you have any of the warning signs of a faulty rear differential, it is important for driving comfort and safety to get an inspection quickly and corrective maintenance or repairs as needed:
Service begins when our certified technician removes the differential cover. We will then remove the old oil and clean away any lingering fluid or metal shavings from within the case. The cover will then be placed back on to reseal the differential before adding fresh oil to specifications.
If the inspection finds that a bearing is damaged or gear has missing teeth, it could be possible to repair the component and escape replacement. If the side and pinion bearings are damaged, we can repair these components with a bearing overhaul.
If the differential is damaged beyond repair, it will need to be replaced to restore specifications. Our rear differential replacement service features a certified technician and a genuine OEM part. This will include the housing, gears, bearings, seals, and oil.
