However, if you're determined to do it yourself, here's a general outline. Remember this is a general guide, and your specific truck's configuration might vary slightly. Always consult a repair manual specific to your year and model GMC 1-ton pickup. A Haynes or Chilton manual would be extremely helpful.
Tools You'll Likely Need:
* Jack and jack stands: Securely support the truck. Never work under a vehicle supported only by a jack.
* Wheel chocks: To prevent the truck from rolling.
* Lug wrench: To remove the wheels.
* Socket set and wrenches: Various sizes will be needed. Metric and SAE sizes are common on these trucks.
* Tie rod end separator/pickle fork: To separate the tie rod end from the steering knuckle. A ball joint separator might also be necessary.
* Tie rod end wrench: This specialized wrench helps prevent damage to the tie rod end while loosening it.
* Torque wrench: Essential for tightening components to the manufacturer's specifications.
* Wheel alignment tools: After replacing the tie rods, a wheel alignment is absolutely crucial. This usually requires specialized equipment.
* Penetrating oil (PB Blaster, etc.): To help loosen rusted or seized fasteners.
* Safety glasses and gloves: Always protect yourself.
General Steps (Consult your repair manual for specifics):
1. Safety First: Engage the parking brake, chock the wheels, and disconnect the negative battery terminal.
2. Raise and Support the Truck: Safely raise the front of the truck and secure it on jack stands.
3. Remove the Wheel: Remove the wheel from the affected side.
4. Disconnect the Tie Rod End: This is the most challenging part. You'll need to use the tie rod end separator/pickle fork to separate the tie rod end from the steering knuckle. Apply penetrating oil generously beforehand and work carefully to avoid damaging the knuckle.
5. Disconnect the Tie Rod: Depending on the design, you might need to loosen a jam nut before unscrewing the tie rod from the steering rack. Use the appropriate wrench to prevent rounding off the nut.
6. Install the New Tie Rod End: Install the new tie rod end, making sure it's properly seated. Tighten the jam nut and the tie rod connection according to the manufacturer's specifications using a torque wrench.
7. Reconnect the Tie Rod End: Carefully connect the new tie rod end to the steering knuckle.
8. Lower the Truck: Carefully lower the truck.
9. Reconnect the Wheel: Install the wheel and tighten the lug nuts securely.
10. Wheel Alignment: This is critical. Take your truck to a professional alignment shop to have the wheels properly aligned. Driving with improperly aligned wheels is dangerous.
Important Considerations:
* Marking: Before disconnecting anything, make marks to indicate the original position of the tie rod ends. This helps with reassembly and alignment.
* Thread Direction: Pay close attention to the thread direction when disconnecting and connecting the tie rod.
* Torque Specs: Always consult your repair manual for the correct torque specifications for all fasteners. Over-tightening can cause damage.
This is a simplified overview. A detailed repair manual for your specific vehicle is crucial for success. Again, if you're not experienced in this type of repair, have a professional mechanic do it. The cost of a professional alignment is far less than the cost of an accident caused by improperly installed tie rods.
