* Front and Rear Drive Shafts: These are crucial. Look for them near the ends of the drive shafts where they connect to the axles and transfer case.
* Steering Linkage: Several grease fittings are usually found on the tie rod ends, drag link, and other components of the steering linkage.
* Suspension: Check the ball joints (upper and lower control arms), and the leaf springs (if equipped) for zerks.
* U-Joints (Universal Joints): These are found on the driveshafts. Each U-joint usually has one or two zerks.
* Leaf Spring Shackles (if applicable): If your Wrangler has leaf springs, there may be grease fittings on the shackles.
* Track Bar: The track bar connects the axle to the frame; it might have a zerk.
To find them effectively:
1. Consult your owner's manual: This is the best resource as it will show the specific locations for your exact model and trim level.
2. Use a flashlight: Grease fittings are small and can be difficult to spot, especially in dark or hard-to-reach areas.
3. Look carefully: Inspect all suspension and drivetrain components thoroughly.
4. Online resources: Search online for "2009 Jeep Wrangler grease fitting diagram" – you might find pictures or videos showing their location. Be aware though that variations exist between models.
Important Note: Failure to regularly lubricate these fittings can lead to premature wear and failure of components, potentially causing serious damage or accidents. If you are unsure about locating or lubricating these fittings, take your Jeep to a qualified mechanic.
