Shock And Strut Replacement at Johnny's Automotive

Worn shocks and struts don't fail all at once. They let the car float, dive under braking and chew up tires. We measure the wear instead of guessing at it.

How do you know when shocks or struts are actually worn out?

Shocks and struts don't hold your car up. The springs do that. A damper's job is controlling what the spring does next, so the body settles once after a bump instead of bouncing three or four more times. A worn damper still lets the car sit at the correct height. It has just stopped managing the motion.

That's why this wear is so easy to miss. It shows up over years, never overnight. First the car floats a little on the highway. Then the nose dives further under braking than it used to. Then the tires start wearing in scallops or patches, because the wheel is bouncing on the road instead of staying pressed to it. Nobody notices any single day of that. You just adapt.

The old bounce test, where you push down on a fender and count the rebounds, catches the very worst ones and misses almost everything else. Plenty of dampers that pass it lost real control a long time ago. What actually tells the story is a body that's weeping or leaking oil, a mount that's broken down, how the strut behaves through its travel, and the tire wear on that same corner.

The difference in one sentence: a shock is a standalone damper mounted next to the spring, while a strut is a damper built into an assembly that also helps hold the wheel in position.

We replace dampers as a pair on the same axle. A fresh one on the left with a tired one on the right makes the car brake unevenly and loads the two tires differently, which is a strange way to spend money. And because struts help set wheel angles, strut work gets an alignment afterward. We say that up front so it's part of the number you agreed to, not a surprise at pickup.

Why us

Why choose Johnny's Automotive for shock and strut replacement

We are your trusted partner for all shock and strut replacement needs.

Measured wear beats it feels fine

Dampers wear too slowly for a seat-of-the-pants verdict to mean much. We inspect the damper, the mount and the tire wear on that corner, and you get photos of what we found sent to your phone.

ASE certified technicians on the job

Strut work involves spring compression and torque specs that matter, so the people doing it are ASE certified and they set fasteners at ride height where the vehicle calls for it.

Alignment in the same visit

Struts help hold your wheel angles, so replacing them moves the alignment. Ours is done here, right after the strut work, which is why we quote the two together instead of treating it as an extra.

FAQ

Shock And Strut Replacement questions, answered

Common questions about our shock and strut replacement services.

Is there a mileage where shocks and struts should be replaced?

There isn't an honest universal number, and we're not going to invent one for you. Road quality, how much weight the vehicle carries and how it's driven all change the answer. We judge it on condition: leakage, mount damage, how the strut behaves through its travel and what the tires on that corner look like.

Can I just replace the one that's leaking?

Physically yes, but we don't recommend it. The other side of that axle has the same miles and the same wear, so a new damper next to a tired one makes the car respond unevenly side to side. Doing the pair also means the labor gets done once.

What is a loaded or quick strut, and is it a good idea?

It's a preassembled unit with the strut, spring and mount already together. It usually costs a bit more in parts and less in labor, and it replaces the mount and spring that have been aging right alongside the strut. On some vehicles it's clearly the better value, on others it isn't, and we'll tell you which one you're looking at.

Will new struts fix my rough ride?

If the roughness comes from the car never settling, yes, that's exactly what dampers do. If it comes from overinflated tires, a stiff tire choice or a bent wheel, new struts won't touch it. We check those first so you're not buying parts for the wrong problem.
