Tools you'll likely need:
* Jack and jack stands
* Wheel chocks
* Socket wrench set (including metric sizes)
* Torque wrench
* Hammer
* Pry bar (possibly)
* Penetrating oil (like PB Blaster)
* Drain pan (for any residual fluid)
* Safety glasses and gloves
Steps (general):
1. Safety First: Secure the S-10 on level ground using jack stands under the frame after raising it with a jack. Chock the wheels. Disconnect the negative battery terminal.
2. Locate the Driveshaft: Identify the driveshaft you need to remove (rear driveshaft for most S-10s).
3. Support the Differential (Rear): If removing the rear driveshaft, you'll need to support the differential to prevent it from dropping. This might involve using a jack under the differential.
4. Disconnect the Driveshaft: This usually involves these steps:
* Exhaust System: The exhaust system may be in the way. You might need to loosen or remove some exhaust components to gain access.
* U-joints: The driveshaft connects to the transmission (or transfer case in 4WD) and the differential via U-joints. You'll need to remove the bolts holding the yoke to the U-joint on both ends of the driveshaft. Apply penetrating oil to these bolts beforehand to help break them loose.
* Slip Yoke (if applicable): Some driveshafts have a slip yoke at one end. This allows for changes in driveshaft length during suspension travel. You may need to separate this before removing the driveshaft completely. A pry bar might be helpful here.
5. Remove the Driveshaft: Once the bolts are removed, carefully lower the driveshaft. It may be heavy.
6. Clean and Inspect: Inspect the driveshaft for any damage or wear.
7. Reassembly (Reverse Order): When reinstalling, be sure to torque the bolts to the manufacturer's specifications (found in a repair manual).
Important Considerations:
* 4WD vs. 2WD: The process is different for 4WD S-10s due to the presence of a transfer case. A 4WD S-10 will have a front and a rear driveshaft.
* Transmission Fluid: Removing the driveshaft might cause some transmission fluid leakage. Have a drain pan ready.
* Repair Manual: This is crucial. A repair manual specific to your 1998 Chevy S-10 will provide detailed, illustrated instructions and torque specifications. This will avoid damage and ensure proper reassembly.
