Raise the front of the vehicle and securely support it on jack stands. Drain the transaxle lubricant. Remove the right drive axle. Remove the exhaust pipe bracket and bearing support-to-engine block bolts, and slide the intermediate shaft out of the transaxle. Be careful not to damage the differential seal when pulling out the shaft. Check the support bearing for smooth operation by turning the shaft while holding the bearing. If it feels rough or sticky, it should be replaced. Take it to a dealer service department or other repair shop, as special tools are needed for this job. Lubricate the lips of the transaxle seal with multi-purpose grease. Carefully guide the intermediate shaft into the transaxle side gear, then install the mounting bolts through the bearing support. Tighten the bolts. Reinstall the drive axle. Refill the transaxle with the proper type and amount of lubricant.

Raise the rear of the vehicle, securely support it on jackstands, and block the front wheels. With the parking brake off and the transaxle in Neutral, inspect the driveshaft for dents or cracks. If dents or cracks are present, the driveshaft needs replacement. Examine for oil leakage at the driveshaft's front and rear; leakage at the transfer case suggests a faulty seal, while leakage at the differential suggests a defective pinion seal. Have an assistant rotate a rear wheel to check the driveshaft's movement. Listen for noise from the center bearing and inspect the rubber portion for cracks or separation. To check the universal joints' condition, twist them with your hands. If there's movement or noise, the driveshaft should be replaced. To measure driveshaft runout, use a dial indicator, and if the runout is beyond the allowable limit, replace the driveshaft. Ensure the driveshaft mounting bolts are tight. For removal and installation, after supporting the vehicle on jackstands and ensuring the transaxle is in Neutral, make reference marks on the driveshaft flanges, the differential pinion flange, and the transfer case pinion flange. This preserves the driveshaft balance during reinstallation. Next, remove the rear universal joint bolts, using a screwdriver to prevent shaft rotation while loosening the bolts. Detach the driveshaft safety loops and the center support bearing from the floorpan. Unbolt the driveshaft front from the transfer case flange and take out the driveshaft assembly. When reinstalling, follow the reverse procedure, aligning the marks on the flanges, and ensuring all fasteners are tightened.
