* Suspension: This is the most likely place. Look for zerks on:
* Ball joints (upper and lower): Usually near the top and bottom of the control arms.
* Tie rod ends: Located at the ends of the tie rods.
* Pitman arm: Connects the steering box to the center link.
* Idler arm: Supports the center link.
* U-joints (drive shafts): On the ends of the driveshafts, usually two per u-joint.
* King pins (if equipped): These are less common on later model trucks, but some may still have them.
* Other Potential Locations:
* Leaf spring shackles (if applicable): Depending on the suspension setup.
* Steering linkage: Various parts of the steering linkage may have zerks.
* Wheel bearings (less common on later models): Wheel bearings on some older trucks had grease fittings, but this is less common on 1997 models. Most likely they are sealed units.
To find them, you'll need to:
1. Consult a repair manual: A factory service manual for your specific year and model Z71 will be the most accurate resource. It will have diagrams showing the locations of all grease fittings.
2. Visually inspect the truck: Carefully examine the suspension components, looking for small, nipple-like fittings. They are often metal and capped.
3. Use a flashlight: Make sure you can see into all the nooks and crannies.
4. Clean the area: Dirt and grime can obscure grease fittings, so cleaning the suspension components beforehand will help you spot them.
Caution: Don't force a grease gun into a fitting if you're unsure. You could damage the component. If you're not comfortable working on your truck, take it to a mechanic.
