Tools You'll Need:
* Jack and jack stands: Essential for safety. Never work under a vehicle supported only by a jack.
* Wheel chocks: To secure the vehicle.
* Socket set (metric): Various sizes will be needed.
* Wrench set (metric): Again, various sizes.
* Transmission jack (highly recommended): This will make the job significantly easier and safer. Otherwise, you'll be relying on sturdy jack stands and potentially some creativity.
* Clutch alignment tool: Crucial for reinstalling the clutch properly.
* Torque wrench: To tighten bolts to the manufacturer's specifications.
* Drain pan: For collecting transmission fluid.
* Rags or shop towels: To clean up spills.
* Penetrating oil (PB Blaster or similar): To help loosen rusted bolts.
* New clutch slave cylinder: Make sure you get the correct one for your vehicle.
Procedure:
1. Safety First: Engage the parking brake, chock the wheels, and raise the vehicle securely using the jack and jack stands.
2. Drain Transmission Fluid (if necessary): Depending on your access to the slave cylinder, you might need to drain some or all of the transmission fluid. This usually requires removing the transmission fill plug. Have your drain pan ready!
3. Access the Slave Cylinder: This is the most variable part of the process. The slave cylinder is typically located on the transmission, near the clutch fork. You'll likely need to remove some components to access it. This *could* involve:
* Removing the transmission inspection cover (if applicable): This will give you a better view and easier access.
* Removing the starter: Often necessary for better access.
* Removing parts of the exhaust system: In some cases, parts of the exhaust may obstruct access to the slave cylinder.
* Possibly removing the bellhousing: This is the more difficult option, but depending on your ranger's year and build, it may be the only option.
4. Disconnect the Slave Cylinder:
* Disconnect the hydraulic line: Carefully disconnect the hydraulic line from the slave cylinder. You'll likely need to use a wrench to loosen a fitting. Have rags ready to absorb any spilled fluid.
* Remove the slave cylinder mounting bolts: Carefully remove the bolts securing the slave cylinder to the transmission.
5. Install the New Slave Cylinder:
* Install the new slave cylinder: Carefully install the new slave cylinder, making sure it's properly aligned.
* Reconnect the hydraulic line: Carefully reconnect the hydraulic line.
* Tighten the mounting bolts: Tighten the mounting bolts to the manufacturer's specified torque.
6. Reassembly: Reinstall any components you removed to access the slave cylinder (starter, exhaust components, etc.).
7. Bleed the Clutch Hydraulic System: This is crucial. Air in the lines will make the clutch pedal feel spongy or not engage properly. You'll need to bleed the system using a bleeder screw located on the slave cylinder. Two people are recommended for this: one to pump the clutch pedal and one to open and close the bleeder screw.
Important Considerations:
* Consult a Repair Manual: A repair manual specific to your 1999 Ford Ranger 3.0L will provide detailed instructions and diagrams. This is highly recommended.
* Transmission Fluid: Be prepared to top off the transmission fluid after the repair.
* Clutch Alignment Tool: Absolutely essential for reinstalling the clutch fork correctly if you removed the transmission.
* Professional Help: If you're not comfortable with any part of this process, take your vehicle to a qualified mechanic. Improper repair can lead to damage to your transmission or clutch.
Remember, this is a simplified overview. The exact procedure will vary based on your specific vehicle. Always consult a repair manual for detailed instructions and torque specifications. Safety should be your top priority when working under a vehicle.
