Symptoms
- Ratchet spins freely without turning the socket
- No clicking sound when switching direction
- Ratchet works in one direction but not the other
- Handle feels loose or gritty when turning
Likely causes
- CommonDirt, grease buildup, or metal debris jamming the internal pawlThe small pawl and gear teeth that engage the socket can get gummed up over time.
- CommonDirectional switch not fully engagedA switch left between settings can prevent proper engagement in either direction.
- PossibleWorn or broken pawl and springThe small spring-loaded pawl inside can wear out or break after years of heavy use.
- Less commonWater intrusion causing internal corrosionRust on the internal gear teeth can prevent proper engagement.
What to do
- Confirm the directional switch is fully set to one side, not stuck in the middle.
- Spray the head of the ratchet with a degreaser to flush out old grease and debris, then work the mechanism by hand several times.
- Apply a few drops of light machine oil into the head after cleaning and work it in by ratcheting back and forth.
- Check the socket drive for any visible wear or looseness at the square drive connection.
- If it still freewheels or won't click after cleaning, the internal pawl or spring is likely worn or broken and typically isn't user-repairable on sealed ratchets.
- Replace the ratchet if it's a sealed, non-serviceable model, since parts and repair often cost more than a new one.
- For a repairable model, some manufacturers sell internal rebuild kits with new pawls and springs.

When to call a pro
Not typically a professional job; higher-end ratchets from major brands often have a lifetime warranty covering exactly this kind of internal failure.
