Term

level ride system

A level ride system is meant to keep the car sitting level. If it breaks or acts up, the car can end up higher or lower on one end—sometimes a lot.

Term

air suspension

Air suspension is a system that uses air pressure to raise or lower the car. It can automatically keep the car level when you have extra weight in the back.

Term

ride height

Ride height is how high the car sits from the ground. When it changes, the car can look/handle different—especially when you load up the trunk or back seat.

Term

bladders

Bladders are the air-filled parts of the suspension. When they get filled with air, they expand and help lift the car.

Term

air compressor

The air compressor is the pump that makes the air pressure for the suspension system. When the car needs to sit higher, it runs and fills the air parts.

Term

tire wear

Tire wear is how fast your tires get worn down. If the suspension height is wrong, the tires can be forced to scrub or wear unevenly.

Term

sensors

Here, “sensors” are the car’s measuring devices. They tell the suspension system things like how heavy the car thinks it is, and if they’re wrong, the car can adjust itself at the wrong time.

Brand

Lincoln Mercury dealer

A Lincoln Mercury dealer is an official car service shop for those brands. If a problem is confusing, the dealer may have the right computer diagnostics and repair instructions.

Car

fully restored classic Volkswagen 1965 21-window deluxe micro bus

They’re talking about a classic 1965 Volkswagen van with lots of windows—specifically the 21-window “deluxe” version. It’s been restored so it looks and feels like a well-kept vintage vehicle, not a worn-out one.

Term

heavy-duty shocks

Shocks are parts that help your vehicle settle after hitting bumps. Heavy-duty shocks are stronger versions meant for heavier use, like carrying lots of passengers.

Term

axle

An axle is the shaft and assembly that transmits power and/or supports the wheels, depending on the vehicle layout. In this context, the host is talking about diagnosing a noise by checking along the axle and then identifying it as coming from the front axle.

Term

stethoscope

A mechanic can use a stethoscope to listen for where a weird noise is coming from. It helps them narrow down the problem area without guessing.

Term

bearing

A bearing is a small part that helps moving parts rotate smoothly. If a bearing wears out, it can make loud squeaks or grinding noises.

Term

torsion bars

Torsion bars are like a spring made from a thick metal bar. When the wheel goes up and down, the bar twists to help support the car.

Term

upper control arm

A control arm is a metal link that holds the wheel in the right position. The upper one is the link higher up that helps the wheel move smoothly.

Term

lower control arm

The lower control arm is another metal link that supports the wheel from below. Together with the upper arm, it helps the wheel move without losing alignment.

Term

ball joint

A ball joint is a joint that lets the suspension move while still holding the wheel in place. Some ball joints have a grease fitting so they stay lubricated.

Term

grease fitting

A grease fitting is a small nipple where you pump grease into a moving part. It’s there so the part can be lubricated during maintenance.

Part

control arms

Control arms are parts in the suspension that help hold the wheel in the right position. If the joints get dry, they can make annoying noises. Greasing them can quiet the sound if that’s where the noise is coming from.

Term

36 horsepower

Horsepower is how much power the engine makes. “36 horsepower” is pretty low, so the vehicle won’t feel strong on hills or at higher speeds. That’s why they say it only works well on flat ground and slow driving.

Place

Coronado

Coronado is a place they’re talking about, and they’re pointing out that it has hills. Since this bus has low power, hills would make it struggle. So it only makes sense if you’re driving on flatter routes.

1997 Honda Civic EX
Car

1997 Honda Civic EX

This is a 1997 Honda Civic in the EX trim. It’s a common, everyday compact car from the late 1990s, and people often pick it because it’s generally simple to maintain and parts are easy to find.

Ferrari 328 Gts
Term

reverse gear

Reverse gear is the part of the car’s gearbox that lets you drive backward. When you shift into reverse, the transmission has to line up the right gears so the car can move back.

Term

gear crunch

A gear crunch is the harsh grinding/cracking sound (and feel) that happens when gears try to engage without proper speed matching. It often points to worn synchronizer parts or incorrect shift timing/speed when selecting a gear.

Term

synchronizer

A synchronizer is like a timing helper inside the gearbox. It makes sure the gears spin at the right speed before they click together—so you don’t get grinding or a harsh crunch when shifting.

Term

transmission rebuilt

A transmission rebuild is when a shop takes the gearbox apart and fixes or replaces the worn parts inside. It’s a bigger job than just adjusting something.

Term

clutch disengaging

When you press the clutch pedal, it should fully separate the engine from the gearbox. If it doesn’t, shifting can feel rough or grind because the gears aren’t fully released.

Term

friction point

The friction point is the spot on the clutch pedal where the car starts to “grab” and move power to the transmission. If that spot is wrong, the clutch may be worn or misadjusted.

Term

clutch free play

Clutch free play is the little “slack” you feel at the top of the pedal before it starts doing anything. If there’s essentially none, it can mean the clutch isn’t set up correctly.

Part

clutch master cylinder

The clutch master cylinder is a hydraulic part that helps move the clutch mechanism. If it’s not working right, the clutch won’t release or engage correctly.

Part

slave cylinder

The slave cylinder is the part that actually pushes the clutch to release it. It can sometimes be fixed by replacing just that part instead of the whole system.

Part

clutch itself

If the clutch parts themselves are worn out or damaged, you may need to replace the clutch. The host is saying this is usually the next step if the hydraulic parts don’t solve it.

Part

rebuild the transmission

Rebuilding the transmission is a big repair where they take the gearbox apart and fix internal parts. The host is saying you only get to this step if the simpler clutch-hydraulics and clutch replacement don’t work.

Car

Subaru wagon

They’re saying their 1989 Subaru wagon did the same turn-signal blinking behavior. That helps show it’s likely a common electrical problem that can show up on different cars.
