How to remove and install a front differential on BMW 328i?

This is a difficult procedure for the home mechanic, as it requires an engine lifting device and a transmission jack. Disconnect the negative battery cable. Block the rear wheels. Raise the front of the vehicle and securely support it on jackstands. Remove the fasteners, engine splash shield, and the shield below the radiator. Remove the cabin air filter housing. Remove the engine air filter housing. Open the hood to the most upright position and attach an engine lift or engine support assembly to lifting points on the engine. The engine only needs to be raised enough to remove the weight from the engine mounts. On the left side, disconnect the tie-rod end, tension strut, control arm, and the strut-to-steering knuckle pinch-bolt. Remove the driveaxles. Remove the bolts and the front subframe reinforcement panel, if equipped. Disconnect the vent hose from the differential case. Make match-marks on the front differential flange and the front of the driveshaft, as well as the rear of the driveshaft and the flange at the transfer case. Remove the bolts securing the driveshaft front yoke to the differential flange. Remove the bolts securing the driveshaft rear flange to the transfer case, and remove the driveshaft from the vehicle. Remove one subframe mounting bolt and purchase new bolts that are 2.5 inches longer. With a suitable support under the subframe, replace each of the subframe mounting bolts with the longer bolts. Lower the subframe two inches to access the differential-to-oil pan mounting bolts. Remove the differential from the vehicle. Installation is the reverse of removal, noting the following points: This is a good time to replace the driveaxle oil seals while the differential is out of the vehicle. Use a new O-ring between the oil pan and the differential. Use the original subframe bolts or new bolts of the same length as the original. Check and top-off the lubricant in the differential.

What steps should be taken if the differential produces a low pitched rumbling noise or a howling noise on BMW M3?

What if the differential results in a low pitched rumbling sound, the first way is to examine the fluid level, type and quality, the second way is to drain the fluid and replace it with a recommended lubricant. Also, check the differential bearings and remove it to check the drive and the driven gears, other components should also be replaced if damaged. For howling noise from the differential also check the level of, kind of and quantity of lubricant, replace with recommended lubricant for the differential, Examine the differential drive and driven gears for signs of wear or damages replace with the new as advised.

What is the configuration and function of the front axle differential, right side bearing pedestal, and related components on BMW X5?

The front axle differential and the right side bearing pedestal are bolted to each side of a modified oil pan. Power is transmitted to the front differential from the transfer case via a driveshaft, and out to front drive hubs through two drive axles. The right drive axle inner constant velocity (CV) joint shaft extends through the oil pan into the front differential.

BMW Differential

The BMW differential is a device couples the drive to the haft-shafts that connect to the rear drive wheels and splits the engine torque two ways, allowing the wheels to spin at different speeds. Most importantly, differential enables the outer drive wheel to rotate faster than the inner drive. This is necessary because when the vehicle turns, the wheel on the outside of the turning curve needs to roll farther and faster than the other.

Q: How to remove and install a front differential on BMW 328i?
A:
This is a difficult procedure for the home mechanic, as it requires an engine lifting device and a transmission jack. Disconnect the negative battery cable. Block the rear wheels. Raise the front of the vehicle and securely support it on jackstands. Remove the fasteners, engine splash shield, and the shield below the radiator. Remove the cabin air filter housing. Remove the engine air filter housing. Open the hood to the most upright position and attach an engine lift or engine support assembly to lifting points on the engine. The engine only needs to be raised enough to remove the weight from the engine mounts. On the left side, disconnect the tie-rod end, tension strut, control arm, and the strut-to-steering knuckle pinch-bolt. Remove the driveaxles. Remove the bolts and the front subframe reinforcement panel, if equipped. Disconnect the vent hose from the differential case. Make match-marks on the front differential flange and the front of the driveshaft, as well as the rear of the driveshaft and the flange at the transfer case. Remove the bolts securing the driveshaft front yoke to the differential flange. Remove the bolts securing the driveshaft rear flange to the transfer case, and remove the driveshaft from the vehicle. Remove one subframe mounting bolt and purchase new bolts that are 2.5 inches longer. With a suitable support under the subframe, replace each of the subframe mounting bolts with the longer bolts. Lower the subframe two inches to access the differential-to-oil pan mounting bolts. Remove the differential from the vehicle. Installation is the reverse of removal, noting the following points: This is a good time to replace the driveaxle oil seals while the differential is out of the vehicle. Use a new O-ring between the oil pan and the differential. Use the original subframe bolts or new bolts of the same length as the original. Check and top-off the lubricant in the differential.

Q: What steps should be taken if the differential produces a low pitched rumbling noise or a howling noise on BMW M3?
A:
What if the differential results in a low pitched rumbling sound, the first way is to examine the fluid level, type and quality, the second way is to drain the fluid and replace it with a recommended lubricant. Also, check the differential bearings and remove it to check the drive and the driven gears, other components should also be replaced if damaged. For howling noise from the differential also check the level of, kind of and quantity of lubricant, replace with recommended lubricant for the differential, Examine the differential drive and driven gears for signs of wear or damages replace with the new as advised.

Q: What is the configuration and function of the front axle differential, right side bearing pedestal, and related components on BMW X5?
A:
The front axle differential and the right side bearing pedestal are bolted to each side of a modified oil pan. Power is transmitted to the front differential from the transfer case via a driveshaft, and out to front drive hubs through two drive axles. The right drive axle inner constant velocity (CV) joint shaft extends through the oil pan into the front differential.
