"Clutch pedal squeak in your 1995-99 Toyota Tacoma? On inline Four models, replace the pedal bracket (PN 55107-04010). On V6s, clean the grease from the torsion spring, and then replace the pedal (PN 31310-35050) and U-bushing (PN 90389-05017) if the spring support is worn. Don't add more grease. TSB TC005-99."
A Toyota dealer replaced my bushing at about 35K miles but the squeak came back about a year later. They didn't replace the pedal, like the TSB says. I plan on having them try to fix it again when I get a chance.
