Fix That Click
My car runs fine, but it has a click in the drivetrain that’s driving me nuts. ;ere’s nothing in the
axles or driveshafts, and the gears aren’t worn. Any ideas?
Bad bearings can sometimes click, but the most likely culprit of your frustrating noisemaker
is the spur gear. All it takes is a tiny piece of grit to get stuck between the teeth to make you
the mayor of click city.
First, let’s rule out any other sources of the o;ending sound. Remove the pinion gear, and
roll the car: If the click is gone, then the sound is definitely being generated by the pinion or
spur gear. Inspect both slowly and carefully for any debris stuck between the gear teeth—a
magnifying glass helps. All it takes is a grain of sand, so you really have to look. Pick out any
o;ending matter and your car should be click-free.
A tiny bit of grit can
make a lot of noise.
