How can the differential final drive unit be efficiently serviced and checked for oil level on Mercedes-Benz 190E?

This operation is much quicker and more efficient if the car is first taken on a journey of sufficient length to warm the final drive unit up to normal operating temperature. Park the car on level ground, switch off the ignition, and apply the parking brake firmly. For improved access, jack up the rear of the car and support it securely on axle stands, ensuring the car is lowered to the ground and level for accuracy when refilling and checking the oil level. Wipe clean the area around the filler/level plug on the left-hand side of the final drive unit and unscrew it. Position a suitable container under the drain plug and unscrew the plug from the right-hand side of the housing, allowing the oil to drain completely into the container while taking precautions against scalding if the oil is hot. Clean both the filler/level and drain plugs, being especially careful to wipe any metallic particles off the magnetic inserts. Once the oil has finished draining, clean the drain plug threads and those of the transmission casing, then refit the drain plug. If the car was raised for the draining operation, lower it to the ground. Refilling the final drive unit is an extremely awkward operation, so allow plenty of time for the oil level to settle properly before checking it, ensuring the car is parked on flat level ground. Refill the final drive unit with the exact amount of the specified type of oil, then check the oil level; if the correct amount was poured in and a large amount flows out when checking the level, refit the filler/level plug and take the car on a short journey to distribute the new oil fully around the final drive components, then check the level again upon return.

How to assemble the rear and front differentials on Mercedes-Benz C230?

So to assemble the rear differential, you should first re-raise the rear of the car and firmly hold it using jackstands, keeping the transaxle in Neutral with the parking brake off and the front wheels obstructed to keep it still. Drain the differential lubricant, and take off the driveaxles. Use a mark to locate how the driveshaft connects to the pinion flange and then unbolt and finally suspend the driveshaft using a piece of wire without reinforcing the center support bearing. Prop a floor jack under the differential, unscrew all mounting bolts and gradually remove the jack to lift the differential out beneath the car. To install, simply repeat the opposite procedure of removal, making sure that all fittings are tightened to the recommended torque value and ensuring that you put in the correct lubricant in the differential. With AWD models, you can start with the removal of the right side intake air duct, along with the fasteners holding the upper half of the exhaust shielding plate. Lift the front of the car and put jackstands beneath the frame not below the suspension components. Take off the front wheels, driveaxles, intermediate shaft, and then the front driveshaft. Unplug the steering gear return line at the bottom of the differential and remove the front stabilizer bar pivot point off the link rods. Destroy the fasteners that hold the heat shield on the steering gear above the right boot, and then a mounting at the base of the differential. Take away steering gear retaining plate and partially withdraw steering gear. Truss the back section of the subframe with a transmission jack and tie-down using ratchet type straps and have an extra floor jack underneath the rear part of the subframe central rather than underneath the front before lowering. Disassemble the differential lower mount to remove its fasteners that hold the differential to the subframe and take the differential out. To make installation, preferably the reverse of the removal operation, be performed taking precaution not to overlook any of the fasteners, which must always be maintain all tied with the recommended load, and the lubricant commissioned into the differential of lubricant.

Mercedes-Benz Differential

Mercedes-Benz Differential facilitates both rear wheels to rotate at the speed they need to ensure smooth turns and happy tires. The brand itself has a heritage that dates back to 1926 and today shines with sleek design, advanced safety aids and digital brains such as MBUX that listens to natural speech, guides navigation and provides entertainment streaming. Its forward plan, powered by the new MB.OS platform, the software that connects batteries, driver assist features and artificial intelligence to one smart network that grows smarter over time. Energy recovery in the hybrid and electric models demonstrates the commitment to efficiency while timeless styling makes each car stand out in any parking lot. All these qualities highlight the importance of a second mention of Mercedes-Benz immediately suggesting prestige, innovation and everyday usability. Turning back to the drivetrain, the second and last Differential reference addresses the primary function, which is to divide engine torque between the left and right axles to ensure each tire is gripping its portion of the road, avoiding any scrubbing, reducing wear on the tires and providing the driver with stable handling whether raining, snowing or basking in bright sunshine. An open gear set helps with the quiet distribution of power for daily commutes, while optional limited slip hardware assists in sending extra twist to the wheel with traction, augmenting launch and exit speed from corners. Quiet operation, rugged materials and proper lubrication allow this small package of gears to serve the entire line of vehicles with equal reliability and poise.

Mercedes-Benz Differential Parts and Q&A

Differential Case
124-350-63-23
Q: How can the differential final drive unit be efficiently serviced and checked for oil level on Mercedes-Benz 190E?
A:
This operation is much quicker and more efficient if the car is first taken on a journey of sufficient length to warm the final drive unit up to normal operating temperature. Park the car on level ground, switch off the ignition, and apply the parking brake firmly. For improved access, jack up the rear of the car and support it securely on axle stands, ensuring the car is lowered to the ground and level for accuracy when refilling and checking the oil level. Wipe clean the area around the filler/level plug on the left-hand side of the final drive unit and unscrew it. Position a suitable container under the drain plug and unscrew the plug from the right-hand side of the housing, allowing the oil to drain completely into the container while taking precautions against scalding if the oil is hot. Clean both the filler/level and drain plugs, being especially careful to wipe any metallic particles off the magnetic inserts. Once the oil has finished draining, clean the drain plug threads and those of the transmission casing, then refit the drain plug. If the car was raised for the draining operation, lower it to the ground. Refilling the final drive unit is an extremely awkward operation, so allow plenty of time for the oil level to settle properly before checking it, ensuring the car is parked on flat level ground. Refill the final drive unit with the exact amount of the specified type of oil, then check the oil level; if the correct amount was poured in and a large amount flows out when checking the level, refit the filler/level plug and take the car on a short journey to distribute the new oil fully around the final drive components, then check the level again upon return.
Differential Assembly
171-350-04-14-80
Q: How to assemble the rear and front differentials on Mercedes-Benz C230?
A:
So to assemble the rear differential, you should first re-raise the rear of the car and firmly hold it using jackstands, keeping the transaxle in Neutral with the parking brake off and the front wheels obstructed to keep it still. Drain the differential lubricant, and take off the driveaxles. Use a mark to locate how the driveshaft connects to the pinion flange and then unbolt and finally suspend the driveshaft using a piece of wire without reinforcing the center support bearing. Prop a floor jack under the differential, unscrew all mounting bolts and gradually remove the jack to lift the differential out beneath the car. To install, simply repeat the opposite procedure of removal, making sure that all fittings are tightened to the recommended torque value and ensuring that you put in the correct lubricant in the differential. With AWD models, you can start with the removal of the right side intake air duct, along with the fasteners holding the upper half of the exhaust shielding plate. Lift the front of the car and put jackstands beneath the frame not below the suspension components. Take off the front wheels, driveaxles, intermediate shaft, and then the front driveshaft. Unplug the steering gear return line at the bottom of the differential and remove the front stabilizer bar pivot point off the link rods. Destroy the fasteners that hold the heat shield on the steering gear above the right boot, and then a mounting at the base of the differential. Take away steering gear retaining plate and partially withdraw steering gear. Truss the back section of the subframe with a transmission jack and tie-down using ratchet type straps and have an extra floor jack underneath the rear part of the subframe central rather than underneath the front before lowering. Disassemble the differential lower mount to remove its fasteners that hold the differential to the subframe and take the differential out. To make installation, preferably the reverse of the removal operation, be performed taking precaution not to overlook any of the fasteners, which must always be maintain all tied with the recommended load, and the lubricant commissioned into the differential of lubricant.
