🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Disconnect the battery

• Use a 10mm socket and 3/8" drive ratchet to loosen the negative battery terminal clamp.
• Lift the negative cable off and tuck it aside so it cannot spring back to the post.
• Tip: Negative off first, on last.

Step 2: Raise and support the Cherokee

• Lift the front using a floor jack (rated 3-ton minimum).
• Set it down securely on jack stands (rated 3-ton minimum).
• Give the vehicle a gentle push to confirm it is stable.

Step 3: Remove the lower splash shield (if equipped)

• Use a trim clip remover and flathead screwdriver to pop out push-clips.
• Use an 8mm socket with a 3/8" drive ratchet to remove any small bolts/screws.
• Set the shield and fasteners aside in a small pile so nothing gets lost.

Step 4: Locate the starter

• Use a flashlight to find the starter where the engine meets the transmission (bellhousing area).
• You’ll see a small cylinder-shaped motor with a larger battery cable attached to it.

Step 5: Disconnect the starter wiring

• Remove the protective rubber boot from the large starter power terminal by hand.
• Use a 13mm socket and 3/8" drive ratchet to remove the nut on the large battery cable terminal.
• Pull the cable off and move it aside so it cannot touch metal.
• Disconnect the small control connector (signal wire) by pressing the tab; use needle-nose pliers gently if needed.
• Tip: Don’t pull wires—pull connectors.

Step 6: Remove the starter mounting bolts

• Support the starter with one hand.
• Use a 15mm socket, 3/8" drive ratchet, and a 3/8" drive extension set to remove the starter mounting bolts.
• If access is tight, use a universal joint adapter (it helps the socket bend to reach angled bolts).
• Lower the starter out carefully once the bolts are out.

Step 7: Prep the connections

• Use a small wire brush to clean the large cable ring terminal and the starter’s mating electrical surface if dirty.
• Apply a small amount of dielectric grease to the connector seals (not on the metal contact faces).
• Tip: Clean metal helps prevent future no-starts.

Step 8: Install the new starter

• Position the starter into place by hand.
• Start the mounting bolts by hand first to avoid cross-threading.
• Tighten the bolts using a 15mm socket and 3/8" drive ratchet, then finish with a torque wrench.
• Torque to 61 Nm (45 ft-lbs) for starter mounting bolts.

Step 9: Reconnect the starter wiring

• Reconnect the small control connector until it clicks.
• Install the large battery cable onto the starter terminal and install a new nut if supplied.
• Tighten using a 13mm socket and torque wrench.
• Torque to 13 Nm (115 in-lbs) for the large terminal nut.
• Reinstall the rubber protective boot over the terminal.

Step 10: Reinstall the splash shield and lower the vehicle

• Reinstall the splash shield using the 8mm socket and the push-clips with the trim clip remover.
• Raise slightly with the floor jack, remove jack stands, and lower the Cherokee.

Step 11: Reconnect the battery

• Reinstall the negative battery cable using a 10mm socket.
• Make sure the terminal is snug and does not rotate by hand.

✅ After Repair

• Start the engine and confirm it cranks strongly without clicking.
• Turn the engine off and re-check underneath for any loose wiring near the starter.
