Are Subaru u-joints serviceable?
Yes, Subaru u-joints are generally serviceable, meaning they can be repaired or replaced if they become worn or damaged. U-joints are an essential component of the driveline in Subaru vehicles, connecting the transmission to the rear differential and allowing for smooth power transfer and suspension movement.
Understanding Subaru U-Joints
U-joints, also known as universal joints, are mechanical couplings that allow the transmission of rotational motion between two shafts that are not perfectly aligned. In Subaru vehicles, u-joints are used in the driveline to connect the transmission output shaft to the rear differential input shaft, enabling the rear wheels to turn at different speeds when the vehicle is cornering.
Over time, the bearings and other components within a u-joint can wear out, leading to play, vibration, or even failure. This can cause driveline issues and potentially lead to more serious problems if not addressed.
Servicing Subaru U-Joints
Subaru u-joints are generally designed to be serviceable, meaning they can be replaced if necessary. The process typically involves the following steps:
- Removing the driveshaft from the vehicle
- Pressing out the old u-joint
- Pressing in a new u-joint
- Reinstalling the driveshaft and ensuring proper alignment and operation
It's important to note that the specific procedures may vary depending on the Subaru model and year, so it's always best to refer to the manufacturer's service manual or consult a qualified mechanic for guidance.
Preventive Maintenance
To help extend the life of Subaru u-joints, it's recommended to perform regular inspections and maintenance. This may include:
- Checking for any play or looseness in the u-joints
- Inspecting the driveshaft for signs of wear or damage
- Ensuring proper lubrication of the u-joint bearings
- Replacing u-joints at the recommended service intervals, typically every 60,000 to 100,000 miles
By staying on top of u-joint maintenance, Subaru owners can help prevent costly driveline issues and ensure their vehicle continues to perform reliably.
How much does it cost to repair a u-joint?
The average cost for an U-Joint Replacement is between $388 and $432. Labor costs are estimated between $111 and $140 while parts are priced between $277 and $292. This range does not include taxes and fees, and does not factor in your unique location. Related repairs may also be needed.
Should you replace both u-joints at the same time?
So when you need to replace a u-joint, always replace the other one too. If you don't, the other one will fail sooner or later. The failure of that u-joint will cause damage to the new u-joint (that replaced the first one). It's always better to replace both u-joints at once.
How do I know if my universal joint needs replacing?
A common symptom of a failing u-joint is a loud clunking sound when putting the car into drive or reverse.
What are the 3 common symptoms of a bad u-joint?
Common Signs of Bad U Joints
- Unusual noises. You might hear new noises from under the vehicle.
- Vibration or shaking. Feeling an unusual vibration, especially at higher speeds, could be an indication that your U joints are wearing out.
- Difficulty steering.
- Visual inspection.
How much does it cost to replace 2 u-joints?
The average cost for an U-Joint Replacement is between $388 and $432. Labor costs are estimated between $111 and $140 while parts are priced between $277 and $292. This range does not include taxes and fees, and does not factor in your unique location. Related repairs may also be needed.
How often should you grease your u-joints?
Grease universal joints at every oil change. Wipe the grease gun coupler and grease fitting before connecting them so the bearings aren't contaminated by the dirt being pushed into them. Slowly add grease until clean; fresh grease extrudes from all four cup seals.
How many miles do u-joints last?
U-joints last a long time, normally something you'd check after you've turned over 100,000 miles. The rubber seals go bad allowing dirt to get into the bearings, and as they wear down, the U-joint gets sloppy.
What causes a u-joint to fail?
Torsional backlash is one of the most common universal joint problems. Heavy loads, shocks, vibrations due to misalignment, and material wear can lead to loose play (backlash) within the bearings which can ultimately lead to joint failure.
Is it OK to drive with a bad u-joint?
A car with a faulty U-joint will not run for long. Coupled with transmission fluid leakage, a broken U-joint can cause damage to the driveshaft, brake line, transmission line, and many other parts of the vehicle.
What is the life expectancy of a u-joint?
U-joints should last forever – or at least the life of the vehicle. “Should” is the operative word here. U-joints aren't supposed to wear out, but it happens. Also, u-joints can break.
