Chevy truck questions we answer every week
Straight answers from our techs
What is AFM lifter failure on a Chevy Silverado?
Many GM V8s use Active Fuel Management (AFM, also called DOD) to shut off cylinders for fuel economy. The special lifters it uses can fail, causing a tick, a misfire and a bent or worn camshaft if it's ignored.
Warning signs
Ticking or tapping · Misfire · Check engine light · Rough running
What we do
We replace the failed lifters and, if you want it gone for good, do the permanent fix: non-AFM hardware plus a PCM recalibration so the computer matches. AFM is a fuel-economy system, not emissions equipment.
Colorado Springs: A lifter tick that gets worse on cold mornings needs attention before it takes the camshaft.
Why are the gauges on my Silverado stuck or wrong?
On 1999–2006 Silverados, gauges that stick, read wrong or sweep erratically are almost always failed stepper motors inside the instrument cluster.
Common signs
Speedometer stuck · Fuel gauge wrong · Gauges sweeping · Needles dead
What we do
We repair the cluster with new stepper motors instead of replacing the whole unit.
Why does my Silverado shudder at highway speed?
On many 2007-and-newer Silverados, a shudder like driving over rumble strips — often around 25–50 mph — is torque converter shudder, frequently tied to transmission fluid condition.
Warning signs
Shudder on light throttle · Rumble-strip feeling · Vibration when cruising
What we do
We scan the transmission, check the fluid, and service it with the correct fluid — or repair the converter if it's gone too far.
Why does my Chevy truck clunk when I turn the wheel?
On 1999–2006 Silverados, a clunk you can feel through the steering wheel at low speed is usually the intermediate steering shaft.
Warning signs
Clunk when turning · Clunk over bumps · Felt through the wheel
What we do
We confirm it's the shaft — not a ball joint or tie rod — and replace or service it.
Why won't my Chevy truck shift into 4WD?
On many Chevy trucks, 4WD that won't engage is a failed transfer case encoder motor, not a failed transfer case.
Warning signs
4WD light flashing · Won't shift into 4WD · Service 4WD message
What we do
We scan the 4WD system, test the encoder motor and actuator, and service the transfer case.
Colorado Springs: Find out before the first snow — not on the first snowy morning.
Why are my Chevy truck's brake lines rusting?
Steel brake lines on many Chevy trucks corrode from road salt and de-icers until they leak — sometimes with little warning.
Warning signs
Soft brake pedal · Brake fluid leak · Brake warning light · Visible rust
What we do
We inspect the lines, replace the corroded sections or full runs, and bleed the system.
