How to Know If Your Power Steering Rack Is Leaking: Rack and Pinion Diagnosis

A leaking power steering rack announces itself through a combination of power steering fluid pooling near the front axle centerline, a groaning or whining noise when the steering wheel is turned at low speed or at full lock, and a steering wheel that feels increasingly heavy or slow to respond. The power steering rack and […]
Hissing Noise From Engine Bay Only on Cold Start: Every Cause, How to Find It, and What to Do

A hissing noise from the engine bay that occurs only on cold start and disappears as the engine warms up is most commonly caused by a vacuum hose or intake rubber component that has contracted in the cold and developed a small gap at a connection point, or a coolant system hose that seeps steam […]
Banging Noise Under the Car When Going Over Bumps in Rain: Why Wet Conditions Change What You Hear and What Is Actually Breaking

A banging noise under the car that appears specifically when going over bumps in rainy or wet conditions is most commonly caused by a loose splash shield, wheel well liner, or underbody plastic cover that water pressure or spray forces against the vehicle floor or suspension components: creating an impact that does not occur in […]
Can You Drive With a Cracked Radiator if the Leak Is Small? The Honest Answer and What You Risk

Yes, you can technically drive short distances with a small radiator crack that is leaking slowly, but the safe driving distance is not measured in miles: it is measured in how quickly the coolant level drops, and a crack that seems minor at idle can rapidly worsen under the pressure and thermal stress of highway […]

A clunking noise when shifting from park to drive in the morning is most commonly caused by worn drivetrain components: particularly a u-joint with excess play, a loose or failed engine or transmission mount, or a slip yoke that has dried out overnight: that produce a single impact sound when the drivetrain slack is taken […]
How Far Can You Drive With a Leaking Valve Cover Gasket: Oil Loss, Fire Risk, and What the Repair Actually Costs

A leaking valve cover gasket can typically be driven hundreds of miles if the leak is a minor seep with no oil reaching hot exhaust surfaces: however, a leak that allows oil to drip or run onto the exhaust manifold or catalytic converter creates a genuine fire risk and should be treated as an immediate […]
Why This Transmission Slipped Only When Hot: A Valve Body Wear Audit

Two shops told this Explorer owner the same thing: full transmission rebuild, $4,500, minimum. One shop said the clutch packs were “shot.” The other said the solenoids were failing. Neither shop had measured transmission line pressure. Neither shop had measured solenoid resistance hot versus cold. Neither shop had run the transmission at temperature long enough […]
Why We Rejected This Customer’s Transmission Flush Request: A Fluid Teardown

The customer wanted a transmission flush. He had read that flushing transmission fluid every 30,000 miles was standard maintenance and his 2012 Toyota Camry had 165,000 miles on its original factory fluid. The request was reasonable on its face. We declined it, and we explained exactly why. Flushing the transmission on this vehicle had a […]
What 10,000 Miles on a Torn CV Boot Does to a Wheel Joint: Teardown Log

The customer’s exact words were: “I noticed it was torn maybe six months ago, but it wasn’t clicking yet so I figured it was fine.” It was not fine. By the time he brought the 2016 Honda Civic Sport in, the outer CV joint on the right front axle had been operating without its full […]
