CV Joints: The Most Abused Part You Never Think About
NaTasha Brand • June 9, 2025
The Heroes (and Victims) of Your Drivetrain
Your car’s CV (constant velocity) joints are like the hardworking stagehands of a theater production—no one notices them until something goes horribly wrong. These crucial components transfer power from your transmission to your wheels while allowing for smooth steering and suspension movement. Yet, despite their importance, CV joints are often ignored until they fail catastrophically.
At Ric Henry’s Auto Service, we’ve seen too many drivers wait until their CV joints are clicking, clunking, or even spewing grease before addressing the problem. In this post, we’ll break down:
✔ What CV joints do (and why they matter)
✔ The warning signs of failure
✔ Why DIY fixes often make things worse
✔ How proper maintenance extends their lifespan
What Do CV Joints Actually Do?
CV joints are the flexible pivot points between your axles and wheels. They allow:
✅ Power transfer from the engine to the wheels
✅ Smooth steering while maintaining torque
✅ Up-and-down suspension movement without binding
There are two types:
Outer CV joints (connect to the wheels)
Inner CV joints (connect to the transmission/differential)
Both are packed with grease and sealed in a rubber boot—which is usually the first thing to fail.
Symptoms of a Failing CV Joint
1. The Telltale Clicking on Turns
A loud, rhythmic clicking when turning (especially at low speeds)
Means the joint’s bearings are worn out
2. Grease Everywhere (Boot Failure)
A torn boot flings grease onto your wheel, brakes, or undercarriage
Once the grease leaks out, dirt gets in, and the joint fails quickly
3. Vibration Under Acceleration
Worn CV joints cause shuddering or shaking when you press the gas
Often mistaken for wheel balance issues
4. Clunking When Shifting Gears
A loud "clunk" when switching from Drive to Reverse (or vice versa)
Indicates excessive play in the joint
5. Steering Wheel Wobble
If the CV joint is severely worn, it can cause steering instability
Why CV Joints Fail (And How to Make Them Last)
Common Causes of Failure
Torn boots (letting grease out and dirt in)
Lack of lubrication (dry joints wear out fast)
Aggressive driving (hard launches, off-roading)
Age/mileage (most last 80,000–150,000 miles)
Maintenance Tips
✔ Inspect boots regularly (look for cracks/leaks)
✔ Replace torn boots immediately (before the joint fails)
✔ Avoid harsh acceleration (especially on lifted trucks)
Why You Should Leave CV Joint Repairs to the Pros
1. Specialized Tools & Presses Are Required
Removing/installing CV axles often requires hydraulic presses
DIY attempts can damage the axle or transmission
2. Proper Greasing & Sealing Matters
Cheap aftermarket boots often fail prematurely
Incorrect grease leads to early wear
3. Alignment Must Be Checked Afterward
Improperly installed axles can cause vibration or premature wear
At Ric Henry’s Auto Service, we:
🔧 Use OEM-quality CV axles & boots
🔧 Press-fit joints properly (no cheap clamps)
🔧 Check alignment post-repair
🔧 Back our work with a 3-year/36,000-mile warranty
Don’t Wait Until Your CV Joint Sounds Like a Maraca
A failing CV joint won’t heal itself—it’ll just leave you stranded at the worst possible moment. If you hear clicking, see grease leaks, or feel vibrations, bring your car to Ric Henry’s Auto Service before it turns into a much more expensive problem.

Let’s talk about one of your car's most dramatic performers: the brake caliper. This unsung hero doesn’t get the glamour of a shiny new paint job or the roar of a powerful engine, but when it decides to throw a tantrum, you’ll know all about it. Especially when you’re cruising down the Houston Harte or trying to beat the light on Bryant Blvd., a sticking brake caliper isn’t just an annoyance, it’s a safety hazard and a wallet-drainer. Today, we’re diving deep into the world of the sticky caliper. We’ll cover what it is, how to spot its cry for attention, and what to do when it happens here in San Angelo. The Unlikely Hero: What Does a Brake Caliper Actually Do? Think of your brake system as a symphony. You press the pedal (the conductor), and a series of events unfold. Hydraulic fluid (the music) travels through the lines, and its pressure commands the brake caliper to act. The caliper itself is a relatively simple but crucial clamp. It straddles your brake rotor (that shiny, silver disc you can sometimes see behind your wheel) and contains two key components: 1. The Piston: Forced out by the brake fluid pressure when you press the pedal. 2. The Brake Pads: The friction material the piston squeezes against the rotor. When you hit the brake, the piston pushes the brake pads onto the spinning rotor, creating immense friction and converting your car’s kinetic energy into heat, thereby slowing you down. It’s a brilliant, violent, and essential process. The Tantrum: Tell-Tale Signs Your Caliper is Sticking A "sticking" caliper is one that either doesn’t fully release the brake pad from the rotor when you let off the pedal, or it fails to apply pressure evenly. Here’s how it announces its presence: 1. The Car Pulls to One Side: This is the #1 giveaway. When braking, if your car consistently veers sharply to the left or right, it’s a strong indicator that the caliper on that side is sticking and applying more braking force than its counterpart. It’s like your car has a favorite side of the road. 2. The Distinctive Hot & Smelly Aroma: A sticking caliper is constantly creating friction, which means it’s constantly generating heat. After a normal drive, if you smell a sharp, acrid burning odor from one wheel (and we’re not talking about the scent of mesquite from the food trucks), that’s a red flag. Carefully approach the wheel and feel for intense radiant heat. Caution: Don't touch the wheel or rotor! 3. Unusual Grumbling or Dragging Noises: You might hear a constant, low-frequency grinding or rubbing sound that changes with your speed, even when your foot is off the brake. It’s the sound of your brake pad having an unwanted, permanent playdate with your rotor. 4. Your Fuel Economy Takes a Nosedive: Is your gas gauge dropping faster than usual? A stuck caliper is essentially like driving with your foot lightly on the brake all the time. Your engine has to work much harder to overcome that constant drag, burning more fuel in the process. 5. Uneven Brake Pad Wear or Excessive Dust: During a tire rotation or when you just happen to look, you might notice that the inner brake pad on one wheel is significantly more worn than the outer pad, or more worn than the pads on the other side of the car. You might also see more black brake dust on one wheel compared to the others. The Fix: From a Simple Slide to a Full Replacement So, your caliper is staging a sit-in. What now? • The Simple Fix (The Clean and Lube): Sometimes, the issue is just a stuck or corroded slide pin. These pins allow the caliper to float back and forth. A technician can clean and re-lubricate them with high-temperature grease, which often solves the problem. It’s the equivalent of giving the caliper a good talking-to. • The Common Fix (The Rebuild/Replacement): More often, the piston seal inside the caliper has deteriorated, or the piston itself is corroded. In this case, the caliper either needs to be rebuilt with a new seal and piston boot or, more commonly and reliably, replaced entirely with a new or quality remanufactured unit. This is almost always a job for a professional, as it involves the critical hydraulic brake system. Why Trust Ric Henry's Auto Service With Your Brakes in San Angelo?

Here in San Angelo, we know a thing or two about rhythm. There's the two-step at the local dance hall, the steady beat of the Concho River, and the satisfying hum of a perfectly tuned engine cruising down Chadbourne Street. But what happens when that smooth hum turns into a jarring shudder? Before you blame our West Texas roads, you might want to meet one of your engine’s most misunderstood components: the harmonic balancer. This unassuming piece of pulley-laden metal is the little hero keeping your engine from literally shaking itself to pieces. So, let's pop the hood and demystify this crucial part. What in the World Does a Harmonic Balancer Actually Do? Its name sounds like something from a zen garden, but its job is pure automotive grit. Bolted to the front of your engine's crankshaft, the harmonic balancer has one critical mission: to cancel out destructive vibrations. Think of your engine’s crankshaft. It’s spinning at thousands of revolutions per minute, enduring incredible forces from the pistons firing in sequence. These forces create tiny, twisting vibrations known as "harmonics" or "crankshaft whip." Left unchecked, these vibrations can resonate through the engine like a tuning fork, leading to catastrophic failure, think broken crankshafts, wiped-out main bearings, and a repair bill that'll make you sweat even in a San Angelo breeze. The harmonic balancer is the clever countermeasure. It’s a two-part device: a heavy inner hub and an outer ring, separated by a layer of specialized rubber. The outer ring, which drives your accessory belts, is designed to move slightly out of phase with the harmful vibrations, effectively "balancing" them out. It’s the engine’s personal shock absorber, a dampener that keeps the dark, destructive pulse of internal combustion in check. Where Did It Get That Fancy Name? The name is perfectly literal, if a bit scientific. "Harmonic" refers to the damaging vibrational frequencies it fights. "Balancer" describes its function of neutralizing those forces. Some folks call it a "crankshaft damper," which is equally accurate. It’s not balancing weight like a tire; it’s balancing energy. It’s the calm, collected bouncer at the engine’s nightclub, ensuring the chaotic party inside doesn’t tear the building down. Is Your Balancer Waving the White Flag? Symptoms of Failure. That rubber layer is the balancer's heart, and like anything, it ages. Heat from the engine, oil leaks, and just the passage of time can cause the rubber to dry out, crack, and separate. When it fails, it’s not subtle. Here’s what to watch for: • The Engine Shimmy: A noticeable vibration, especially at idle, that feels like the whole car is trembling. It’s not your imagination. • Squealing or Knocking Noises: A worn balancer can cause misalignment of your serpentine belt, leading to an annoying squeal. In severe cases, you might hear a clunking or knocking from the front of the engine. • Visible Damage: Pop the hood and take a look. If you see the outer ring misaligned, the rubber bulging out, or even deep grooves worn into it, it’s time for a replacement. • Accessory Failure: Since it drives your alternator, power steering pump, and A/C compressor, a failing balancer can lead to a dead battery, stiff steering, or a warm cabin on a hot San Angelo afternoon.
