  1. Remove the exhaust system. Remove the crossbrace under the driveshaft. Remove the heat shields. Mark the relationship of the driveshaft flange to the transmission output flange for installation.
  2.  
  3. Use Tool No. 26 1 040 or equivalent to loosen the spline locking ring behind the center bearing.
  4.  
  5. Support the transmission and remove the transmission crossmember, if blocking the access to the coupling. Remove the bolts holding the flex coupling to the transmission output flange. If equipped with a vibration damper, rotate the damper and pull off with the flex coupling.
  6.  
  7. Fill the opening of the bearing with grease. Use a tool the same diameter as the bore in the bearing and drive in. The hydraulic force developed will drive the bearing out from the back side.
  8.  

To install:

  1. Clean the grease from the bore and fill with 2 grams of moly-lubricant grease. Drive the new bearing in until so it protrudes 0.177 inch (4.5mm).
  2.  
  3. Install the front flex coupling and vibration damper. The arrows must face the flange arms. Torque the M10-8.8 bolts to 35 ft. lbs. (48 Nm) and the M10-10.9 bolts to 52 ft. lbs. (72 Nm).
  4.  
  5. Install the transmission crossmember. Torque the spline locking ring to 12 ft. lbs. (17 Nm) for 2 wheel drive and 16 ft. lbs. (22 Nm) for 4 wheel drive.
  6.  
  7. Install the heat shields and crossmember. Install the exhaust system.

Fig. Mounting bolts for the front driveshaft joint (Guibo) disc

  1. Raise and safely support the vehicle.
  2.  
  3. Support the transmission from underneath with the special tools and a floor jack. Remove the nuts and washers from the transmission mounts on top of the rear transmission mounting crossmember. Loosen but do not remove the nuts located underneath which fasten the crossmember to the body. Then, slide this crossmember as far to the rear as it will go.
  4.  
  5. Unscrew the fastening nuts on the forward end of the CV-joint and then discard them.
  6.  
  7. Using a prybar to keep the driveshaft from turning, remove the self-locking nuts and bolts fastening the rear of the driveshaft to the final drive.
  8.  
  9. Remove the bolts fastening the center mount to the body. Bend the driveshaft down and pull the CV-joint off the transmission flange. Cover the joint to keep it clean.
  10.  

To install:

  1. Replace the gasket that fits between the joint bolts.
  2.  
  3. The remaining components are installed in the reverse order from which they were removed. Make sure to replace the self-locking nuts used at either end of the shaft. Preload the center mount forward by forcing the bracket 0.157-0.197 in. (3.98-5.00mm) forward from the neutral position.
  4.  
  5. Reposition the rear transmission mounting crossmember, install the mounting bolts until tight, then secure the transmission to the rear crossmember.
  6.  
  7. Lower the vehicle.

E30 Models



  1. Remove the exhaust system. Remove the crossbrace under the driveshaft. Remove the heat shields. Mark the relationship of the driveshaft flanges to the differential flange and the transmission output flange for installation.
  2.  
  3. Use Tool No. 26 1 040 or equivalent to loosen the spline locking ring behind the center bearing.
  4.  
  5. Support the transmission and remove the transmission crossmember. Remove the bolts holding the flex coupling to the transmission output flange. If equipped with a vibration damper, rotate the damper and pull off with the flex coupling.
  6.  
  7. Remove the bolts at the driveshaft to differential flange.
  8.  
  9. Remove the center bearing bolts and pull the driveshaft down and out. Avoid catching the fuel tank connector pipe at the rear. Avoid severe angles at the joints.
  10.  

To install:

  1. Install the driveshaft and loosely install the center bearing to the body. Connect the rear joint to the differential. If equipped with U-joints, torque to 52 ft. lbs. (72 Nm). If equipped with a constant velocity joint, torque the M8 bolts to 23 ft. lbs. (32 Nm) and the M10 bolts to 46 ft. lbs. (64 Nm).
  2.  
  3. Install the front flex coupling and vibration damper. Torque the M10-8.8 bolts to 35 ft. lbs. (48 Nm) and the M10-10.9 bolts to 52 ft. lbs. (72 Nm).
  4.  
  5. Install the transmission crossmember. Preload the center bearing forward 0.157-0.236 inch (4-6mm) and tighten. Torque the spline locking ring to 12 ft. lbs. (17 Nm).
  6.  
  7. Install the heat shields and crossmember. Install the exhaust system.
