🔧 Wrangler - Engine Mount Replacement
On your Wrangler, the engine mounts support the engine and control vibration. Replacing them requires safely supporting the engine, unbolting the mount(s), and installing new mounts without stressing hoses, wiring, or the exhaust.
Difficulty Level: Advanced | Estimated Time: 2-5 hours
⚠️ Safety & Precautions
- ⚠️ Support the engine correctly before removing any mount bolts.
- ⚠️ Never get under the Jeep with only a jack; use jack stands.
- ⚠️ Use a wood block on the jack to avoid cracking the oil pan.
- ⚠️ Keep hands clear when lifting/settling the engine; pinch risk.
- ⚠️ Work on a cool engine/exhaust to avoid burns.
- ⚠️ Battery disconnect is recommended if working near the starter/alternator wiring.

🔨 Step-by-Step Instructions
Follow these steps in order:
To give you the exact, factory-correct bolt locations and torque specs (they vary by transmission and which mount you’re doing), I need two quick details:
- Are we talking about your Wrangler with an automatic or manual transmission?
- Are you replacing both engine mounts or only left / right?
Once you confirm, I’ll lay out the full numbered procedure.
✅ After Repair
- Inspect for any stretched hoses/wiring and verify nothing is rubbing (fan shroud, exhaust, steering shaft area).
- Start the engine and check for abnormal vibration or clunks in Drive/Reverse (foot on brake).
- Recheck fasteners after a short test drive.
