**TLDR:** Shocks **only damp**; they do not hold weight. Worn ones **lengthen braking** and cup tires. We replace them **in axle pairs** and road-test.

Shock absorbers control how fast your springs move, keeping the tires pressed to the road after bumps. When they wear, the car floats, bounces and dives, and stopping distances grow. Route 66 Auto Repair in Upland checks each shock for leaks, damage and weak damping, replaces them in axle pairs after written approval, and road-tests the ride. Many trucks and SUVs use shocks at the rear and struts up front. If your car uses struts instead, see [strut repair](https://route66autorepairshop.com/suspension-and-steering-services/strut-repair).

## How do worn shocks show up?

- The body keeps moving after a dip instead of settling
- The nose dives hard under braking or squats when accelerating
- Tires develop scalloped, cupped wear
- A loaded truck wallows on the freeway
- Oil wetting the shock body, or a bent or rusted shaft

## Do shocks matter more when you haul or tow?

Yes. A loaded pickup or a car towing a trailer puts more energy into the springs, and worn shocks let that energy bounce around. Wallowing and trailer sway get worse. If you are planning a move, pair new shocks with a hookup check from our [free towing inspection](https://route66autorepairshop.com/u-haul-rentals/free-towing-inspection), which checks the trailer connection itself.

For work trucks, heavier-duty shocks may be an option. We explain the trade-offs in ride comfort before you choose.

## Our shock replacement process

1. **Road test:** We feel for float, dive and bounce on real streets.
2. **Inspect:** Each shock is checked for leaks, shaft damage, and worn mounting bushings.
3. **Quote in pairs:** The estimate lists shocks by axle and any worn mounts or hardware.
4. **Replace and road test:** New shocks are installed and torqued, and we road-test the ride.

## What's included in shock absorber replacement

- Before-and-after road test
- Leak, shaft and mount inspection
- Shocks replaced as an axle pair
- New mounting hardware where supplied
- Tire wear pattern noted

## Need-now or need-later?

**Need now:**
- A leaking or broken shock
- A detached shock mount
- Severe bounce that affects braking

**Need later:**
- Gradual softening with no leaks
- Minor cupping on tires with good tread

## How pricing and timing work

Shocks usually take less time than struts and normally do not require an alignment. Price depends on the vehicle and the shock type you choose. AAA members get 10% off parts and labor, up to $75. Many shock jobs finish the same day when the board allows.

## Aftercare

The car should feel more settled right away. If your tires already have cupped wear, that noise may linger until they are replaced; our [tire services](https://route66autorepairshop.com/tire-services) team can mount new ones when you are ready.

## Frequently asked questions

### How long do shock absorbers last?

It depends on the vehicle, load and roads. Instead of a fixed number, we look for leaks, damage and how the car behaves on a road test.

### Does the bounce test work?

Pushing down on a corner can reveal a badly worn shock, but it misses many. A road test and visual inspection are more reliable.

### Can I replace just one shock?

It is best to replace them as a pair on the same axle so both sides damp equally.
