Drivetrain Services and Repairs
The drivetrain serves two functions: it transfers power evenly from the engine to all drive wheels and it varies the amount of torque. The drivetrain may include the differential, a transfer case (in four-wheel and all-wheel drive cars) and the transmission.
Drivetrain Service and Repair – Differential Services
Why Your Differential Is Important?
An axle connects the two wheels on opposite sides of the vehicle. The differential is a component of your drivetrain, it’s special gear box located between the drive wheels of your vehicle. The differential is comprised of the gears and bearings either inside the transmission or the housing of the axle. It allows the drive wheels to turn at different speeds, as they must when turning a corner. The differential lubrication level should be checked with every oil change. Over time, high operating temperatures can cause the lubricating fluid in the differential to break down, developing a gummy texture that doesn’t properly lubricate the gears. Some differentials require periodic cleaning and repacking of wheel bearings. If you drive an SUV or light truck, and especially if you pull a boat (meaning these components may get submerged in water), axle lube should be changed every year. Please refer to your owner’s manual for factory recommended maintenance intervals for your specific vehicle. Replacing the fluid can help you avoid premature wear on the gears in the differential, help reduce wear on drive-wheel tires, and maximize the life of your differential.
What DNA Automotive will For Your Drivetrain and Differential
DNA Automotive technicians are experts in differentials and axles. Drivetrain or differential problems should be checked out as soon as possible. Symptoms include clunking when you accelerate or shift between drive and reverse, or a high-pitched howling type of noise. We will remove your old differential fluid and replace it with new lubricating fluid based on your vehicle manufacturer’s recommendations.
Drivetrain Service and Repair – Drive Shaft and U Joints
A. drive shaft and universal joints (U-joints), also components of your drivetrain, connect the transmission to the rear axle on most rear wheel drive vehicles. Four wheel drives also use drive shafts and U-joints. U-joints should be inspected at every oil change (and are inspected as part of DNA Automotive’s Comprehensive Maintenance Check. SUVs and light trucks often have drive shaft slip joints that require lubrication. Please refer to your owner’s manual for factory recommended maintenance intervals for your specific vehicle. Bad U-joints often squeak when accelerating from a stop, exhibit a clunking noise when shifting between drive and reverse, or a shuddering when accelerating or driving. Bad U-joints can cause the drive shaft to separate from the vehicle-causing damage to the vehicle and requiring potentially expensive repairs. Bring your vehicle in to the experts at DNA Automotive if you notice any of these symptoms.
Drivetrain Service and Repair – Transfer Case Services (4WD/AWD only)
Why Servicing Your Transfer Case Is Important
The transfer case is a special gear box found in four-wheel and all-wheel-drive vehicles. It is an important component of your drivetrain and connects to both the front and real axes on a four wheel drive vehicle sending drive power from the engine to the front and rear axles. In all-wheel-drive vehicles, the transfer case helps to shift power from one axle to another, depending upon traction conditions. Lubricant fluid in the transfer case helps to keep its gears cool and turning smoothly. Replacing this fluid at appropriate intervals (those suggested by your vehicle’s manufacturer) can help prevent premature wear and damage caused by contaminated or broken-down lubricant. The transfer case should be checked at every oil change for adequate lubrication. Many transfer cases require a regular, periodic change of oil or fluids. Check your owner’s manual for the manufacturer’s recommended maintenance intervals for your specific vehicle.
What Can Happen If You Don’t Regularly Service Your Vehicle’s Transfer Case?
Transfer case problems include a complete loss of four wheel drive operation and the inability to switch between modes when you want to.
What DNA Automotive Will Do For Your Vehicle’s Transfer Case
We use a special fluid is used to lubricate, cool and clean the gears in the transfer case. We will remove the old transfer case fluid and replace it with new fluid that conforms to your vehicle manufacturer’s recommendation. Our technicians are experts in the service and repair of transfer cases and four wheel drive vehicles.
Constant Velocity Shafts And Boots
Constant Velocity (CV) shaft, boot and joints are used on front-wheel drive and many four-wheel drive vehicles. CV boots should be inspected with every oil change. CV boots can be torn or cracked over time, allowing dirt into the joint. Unless such damage is discovered and addressed quickly, both the boot and the joint can become so damaged that they need replacement. In this case, a replacement axle may be your best option. How can you tell if you have a problem with your CV joint? You may hear a clicking noise or a clunk while turning. Or you may experience a shudder. Inspection of your CV Shaft and Boots is a part of our comprehensive maintenance package.
Bearings in the wheels are about the only bearings requiring routine maintenance, common in rear wheel drive vehicles. These bearings should be cleaned, inspected and repacked with grease about every two years or 24,000 miles. Please refer to your owner’s manual for factory recommended maintenance intervals for your specific vehicle. Metal-to-metal noise in the wheels, or steering that veers in one direction or the other, are typical symptoms of a malfunctioning wheel bearing. Bring your vehicle to the experts at George’s Transmission and Auto Repair if you notice either of these symptoms.
