Worth getting checked soon

• Brake pads are wearing thin — most pads have a little metal tab that squeals on purpose to tell you so.
• Pads have glazed over from heat or built up brake dust, which makes them sing without being worn out.
• Surface rust on the rotors after a rainy night — this kind squeals for the first few stops, then goes quiet.

We pull a wheel and measure how much pad is left. If it’s the wear tab, it’s a pad replacement — usually a same-day job. If the pads are fine, cleaning and re-greasing the hardware often settles it down.

Get this looked at right away

• The pads have worn all the way through and metal is now riding on metal.
• A stone or bit of road debris is wedged between the pad and the rotor.
• A stuck caliper is holding one pad against the rotor all the time.

Grinding means the parts are damaging each other every mile you drive, so this gets looked at first. Expect pads at minimum, and often rotors too, since the metal contact scores them.

Worth getting checked soon

• Worn caliper mounting hardware letting the pads shift when they grab.
• A tired sway bar link or control arm bushing taking up slack as weight moves forward.
• Loose or worn engine and transmission mounts letting the drivetrain rock.

This one is a hands-on check — we get it on the lift and work through the front end looking for play. The fix is usually a small part; finding which small part is the actual work.

Worth getting checked soon

• Rotors have worn unevenly, so the pads grab harder in some spots than others.
• Uneven pad material transferred onto the rotor surface, often after hard braking down a hill.
• A sticking caliper heating one corner more than the rest.

We measure the rotors for thickness variation. Sometimes they can be resurfaced; if they’re below spec, they get replaced in pairs so the car stops evenly.

Worth getting checked soon

• A hole rusted through the muffler or a pipe — common on Iowa cars that see winter salt.
• A cracked or leaking exhaust manifold gasket up at the engine.
• A broken exhaust hanger letting a joint pull apart.

We put it on the lift and trace the leak by ear and by eye. Worth not sitting on — an exhaust leak ahead of the cabin can let fumes work their way inside. Small holes can sometimes be patched; rusted-through sections get replaced.

Worth getting checked soon

• Transmission fluid is low or past its life, so the pump is working hard.
• A worn bearing inside the transmission or the torque converter.
• On some cars, a failing power steering or supercharger belt-driven pump making noise under load.

First stop is checking fluid level and condition — that’s quick and rules a lot out. If the fluid looks good, we road test with you along so you can point out exactly when it happens.

Worth getting checked soon

• Engine oil is low, so the top of the engine isn’t getting enough of it.
• A small exhaust leak at the manifold, which ticks in time with the engine.
• Normal valvetrain or fuel injector noise on some engines — a few just tick.

Check the oil level yourself first; if it’s low, top it up and see if the tick quiets down. Either way we’ll want a look, because a low reading means oil is going somewhere it shouldn’t.

Worth getting checked soon

• Fuel octane lower than the engine wants — worth trying a tank of the next grade up.
• Carbon built up in the combustion chambers making hot spots.
• A knock sensor or ignition timing problem the engine can’t compensate for.

We scan for stored codes and check what the engine is doing with its timing. Often it’s a fuel or carbon issue with a straightforward fix; ignoring a steady knock is what turns it into something bigger.

Worth getting checked soon

• The serpentine belt is glazed, cracked, or loose and slipping on the pulleys.
• A worn belt tensioner that isn’t holding the right pressure anymore.
• A pulley or accessory — alternator, water pump, A/C — starting to seize.

Quick visual check of the belt for cracks and glazing. Belts are an inexpensive part and a short job; the reason not to wait is that the same belt turns your alternator and water pump.

• Low oil level letting the valvetrain run noisy.
• Fuel injectors clicking — completely normal on plenty of engines, especially diesels and direct-injection.
• A small exhaust manifold leak that ticks with each cylinder firing.

Check your oil on level ground when the engine is cool. If it’s where it should be and the tick isn’t getting louder, it’s often just the engine’s personality — but let us listen at your next visit.

• A rusted heat shield vibrating against the exhaust pipe — the single most common cause.
• The honeycomb inside the catalytic converter breaking apart.
• A loose exhaust hanger or clamp letting a section knock against the underbody.

Heat shields are the usual culprit and often just need re-securing — a cheap fix and a big improvement in your quality of life. We’ll confirm it isn’t the converter while it’s on the lift.

Worth getting checked soon

• A cracked vacuum hose leaking air — often paired with a rough or hunting idle.
• Coolant dripping onto something hot and steaming off.
• A small exhaust leak escaping under pressure.

Vacuum leaks we find with a smoke test, which makes the leak visible in a couple of minutes. If it’s coolant, that’s worth catching early — overheating is the expensive version of this problem.

Worth getting checked soon

• A misfire from a worn spark plug or a failing ignition coil.
• A dirty throttle body or idle air passage.
• A vacuum leak letting in unmetered air.

We start with a scan — a misfire almost always leaves a code telling us which cylinder. Plugs and coils are routine work. Running on a misfire for long can damage the catalytic converter, which is the part you’d rather not buy.

Worth getting checked soon

• A worn CV joint — the flexible joint that lets the front wheels steer and drive at the same time.
• A torn CV boot that let the grease out and the road grit in.
• Less often, a worn wheel bearing that shows up under cornering load.

Easy to confirm on the lift by looking for a split boot and grease flung around the inside of the wheel. Caught early it can be a boot; left alone the joint wears out and the axle gets replaced.

Worth getting checked soon

• Power steering fluid is low, often because a hose or seal is seeping.
• The power steering pump is wearing out.
• On electric-assist steering, the assist motor or its mounting getting noisy.

We check the fluid and look for where it’s going. Topping it up quiets things down but doesn’t solve a leak — losing assist entirely while you’re turning is the outcome worth avoiding.

• Dry or cracked suspension bushings, common as rubber ages.
• A worn strut mount — the bearing the whole strut pivots on when you steer.
• Ball joints that have lost their grease.

Mostly a comfort issue at first, but these parts hold your wheels where they belong, so we like to lay eyes on them. Some bushings can be lubricated; worn joints get replaced.

Worth getting checked soon

• Worn sway bar end links — the most common cause by a wide margin, and an inexpensive part.
• A worn strut or shock that’s stopped controlling the wheel properly.
• A loose exhaust hanger letting the pipe tap the floor.

We check for play with the car on the lift, which usually finds it in a few minutes. Sway bar links are a quick job; struts are a bigger one, so it’s worth knowing which you’re dealing with.

• A broken exhaust hanger letting the system swing.
• A rusted heat shield hanging loose.
• A loose splash shield or piece of underbody trim.

Almost always found on sight from the lift, and often fixed with a new hanger or clamp. Cheap to sort out, and it stops the noise that’s been driving you up the wall.

• Dry suspension bushings — very common on older cars and after a cold snap.
• Worn shocks or struts.
• Dry sway bar bushings, which squeak more in cold weather.

Not a safety worry on its own. We can often quiet it with the right lubricant on the bushings; if the shocks are worn out, you’ll feel it in the ride as well as hear it.

Get this looked at right away

• On a manual: the clutch isn’t fully releasing, so the gears are still spinning when you ask for the shift.
• On a manual: worn synchros, usually one gear worse than the rest.
• On an automatic: low or burnt transmission fluid.

Grinding is metal wearing away every time it happens, so this one moves to the front of the line. We check clutch adjustment and fluid first — both are far cheaper than what happens if it’s left.

Worth getting checked soon

• Transmission fluid low, old, or the wrong type.
• A worn transmission or engine mount letting the whole drivetrain shift.
• A worn U-joint or driveshaft component taking up slack.

Fluid check and a scan first — modern transmissions report a lot about themselves. Mounts are a straightforward replacement. Fluid problems caught early are the difference between a service and a rebuild.

Worth getting checked soon

• A worn wheel bearing — the classic sign is that the noise changes as you sway the car left and right.
• Uneven tire wear, especially the sawtooth pattern that makes tires roar.
• Aggressive tread on a newer set of tires — some are just loud.

A road test usually tells us which corner, and a spin on the lift confirms it. Bearings are a normal wear item and a routine replacement — but a badly worn one is not something to keep driving on.

• A failing muffler or resonator that’s lost its internal baffling.
• A small exhaust leak that only resonates at certain engine speeds.
• A worn driveline component making a low-frequency hum that carries into the cabin.

We’ll want to hear it, so a short road test at the speed where it happens saves a lot of guessing. Exhaust work is usually straightforward once we know which section is the offender.
