  Q: How to Remove and Install a Starter Motor on a Jeep Grand Cherokee?

  A: Disconnect the cable from the negative terminal of the battery. Raise the vehicle and support it securely on jackstands. Remove the lower splash shield and skid plates, if equipped. On 4WD models with certain transmissions, there's a support bracket between the front axle and the side of the transmission that blocks access to the lower starter mounting bolt. If your vehicle has this support bracket, remove the two support bracket bolts at the transmission, then pry the support bracket aside enough to gain access to the lower starter mounting bolt. Additionally, on some 4WD models the driveshaft will have to be detached from the front differential companion flange for access to the starter mounting bolts. Remove the heat shield, if equipped, from the starter motor. Remove the nut that secures the battery cable to the terminal stud on the starter solenoid, disconnect the cable from the terminal stud and disconnect the electrical connector from the spade terminal on the solenoid. Remove the two starter mounting bolts. Move the starter motor toward the front of the vehicle until the nose of the starter pinion housing clears the transmission bellhousing, then lift the nose down and, if you haven't already done so, lower the starter until you can disconnect the electrical connector and remove the nut that secures the battery cable to the terminal stud on the starter solenoid. Once everything is disconnected, remove the starter. Caution: The starter motor is fairly heavy, so be sure to support it while removing it. Do NOT allow it to hang by the wiring harness. Installation is the reverse of removal. For Hemi engines, loosen the lug nuts on the left front wheel. Raise the vehicle and place it securely on jackstands. Remove the wheel. Remove the splash shield from the left front wheel housing. Remove the starter heat shield and fasteners, if equipped. On some 4WD models with certain transmissions, there's a support bracket between the front axle and the side of the transmission that blocks access to the lower starter mounting bolt. If your vehicle has this support bracket, remove the two support bracket bolts at the transmission, then pry the support bracket aside enough to gain access to the lower starter mounting bolt. Disconnect the battery cable and electrical connector from the terminals on the starter motor solenoid. Remove the two starter motor mounting bolts and remove the starter motor assembly.

  Q: How to Check If a Malfunction Occurs in the Starting Circuit and Starter Motor?

  A: If a malfunction occurs in the starting circuit, check the Battery Cable clamps, battery cables, battery, starter motor wiring, and connections, starter motor mounting bolts, related fuses, ignition switch circuit, starter relay, and TR sensor. If the starter is receiving voltage but does not activate, remove and check the starter motor assembly on the bench. With the starter assembly mounted in a vise on the bench, install one jumper cable from the positive terminal of a test battery to the B+ terminal on the starter. Install another jumper cable from the negative terminal of the battery to the body of the starter. Install a starter switch and apply battery voltage to the solenoid S terminal and observe the solenoid plunger, shift lever, and overrunning clutch extend and rotate the pinion drive.
