Before you start wrenching, take the time to properly diagnose the issue. This will save you time and effort in the long run.

* **Squeaking:**
* **Listen Carefully:** Identify the source of the squeak. Is it coming from the pedal threads, the bearings, or the pedal body?
* **Inspect Pedal Threads:** Check for dirt, rust, or damage on the pedal threads. Clean and lubricate them if necessary.
* **Check Bearings:** Spin the pedal by hand. If it feels rough or gritty, the bearings may be worn or dry.
* **Sticking/Binding:**
* **Spin the Pedal:** Observe how the pedal rotates. Does it spin freely, or does it stick or bind at certain points?
* **Inspect for Dirt and Grime:** Check for dirt, grime, or debris around the axle and bearings.
* **Check for Damage:** Look for any signs of damage to the pedal body, axle, or bearings.
* **Loose Pedals:**
* **Check Pedal Tightness:** Try to wiggle the pedal on the crank arm. If it feels loose, it needs to be tightened.
* **Inspect Pedal Threads:** Check for damaged or stripped threads on the pedal or crank arm.
* **Worn Bearings:**
* **Feel for Play:** Grab the pedal body and try to move it side to side. If there’s noticeable play, the bearings are likely worn.
* **Listen for Noise:** Spin the pedal and listen for grinding or clicking noises, which can indicate worn bearings.
* **Bent Axle:**
* **Visual Inspection:** Look for any visible bends or kinks in the axle.
* **Spin the Pedal:** Observe how the pedal rotates. If it wobbles excessively, the axle may be bent.

2. Removing the Pedals

Removing the pedals is a crucial step in fixing a bike pedal. Remember that pedals have reverse threads – the left pedal tightens counter-clockwise, and the right pedal tightens clockwise.

* **Position the Crank Arms:** Rotate the crank arms so that the pedal you want to remove is facing forward and parallel to the ground.
* **Apply Penetrating Oil (If Necessary):** If the pedals are stuck or rusted, apply penetrating oil to the pedal threads and let it sit for a few minutes.
* **Use a Pedal Wrench:** Place the pedal wrench on the pedal axle flats. Make sure the wrench is fully engaged and secure.
* **Apply Force:** Push down on the wrench with steady, even pressure. Remember the reverse threads: turn the left pedal clockwise to loosen it, and turn the right pedal counter-clockwise.
* **Remove the Pedal:** Once the pedal starts to loosen, continue turning the wrench until it’s completely removed.
* **Repeat for the Other Pedal:** Repeat the process for the other pedal, remembering the reverse threads.

3. Cleaning and Inspecting the Pedals

Once the pedals are removed, thoroughly clean and inspect them for damage.

* **Clean the Pedal Body:** Use a degreaser and a brush to clean the pedal body, removing dirt, grime, and old grease.
* **Clean the Axle:** Clean the axle with a degreaser and a rag. Inspect the axle for any signs of damage, such as bends or cracks.
* **Inspect the Bearings:** If possible, remove the bearings and inspect them for wear or damage. Clean the bearing races (the surfaces the bearings roll on) as well.
* **Check the Threads:** Inspect the pedal threads for damage or stripping. If the threads are damaged, you may need to replace the pedal.

4. Repairing or Replacing the Bearings

If the bearings are worn or damaged, you’ll need to repair or replace them. This process varies depending on the type of pedal.

* **Sealed Bearings:** Some pedals have sealed bearings that cannot be serviced. If these bearings are worn, you’ll need to replace the entire pedal.
* **Loose Ball Bearings:** Other pedals have loose ball bearings that can be cleaned, greased, and reinstalled. To do this:
* **Remove the Old Grease:** Clean the bearing races and ball bearings with a degreaser.
* **Inspect the Bearings:** Check the ball bearings for wear or damage. Replace any damaged bearings.
* **Apply Fresh Grease:** Apply a generous amount of bearing grease to the bearing races.
* **Reinstall the Bearings:** Place the ball bearings back into the bearing races. The number of bearings will vary depending on the pedal.
* **Adjust the Bearing Tension:** Adjust the bearing tension according to the manufacturer’s instructions. The goal is to have the bearings tight enough to prevent play but loose enough to allow smooth rotation.

5. Reinstalling the Pedals

Once you’ve cleaned, repaired, or replaced the bearings, it’s time to reinstall the pedals.

* **Apply Grease to the Threads:** Apply a thin layer of grease to the pedal threads. This will prevent the pedals from seizing and make them easier to remove in the future.
* **Thread the Pedals into the Crank Arms:** Start threading the pedals into the crank arms by hand. Make sure you’re using the correct pedal for each side (the right pedal is usually marked with an “R,” and the left pedal is marked with an “L”).
* **Tighten the Pedals:** Use a pedal wrench to tighten the pedals to the correct torque specification. Consult your bike’s manual or the pedal manufacturer’s instructions for the correct torque value. A typical torque range is 30-40 Nm.
