Most drivers notice bad shock absorbers as a comfort issue first, but the real cost is what worn shocks do to everything else on the truck. Failed or leaking shock absorbers allow excessive suspension movement that accelerates tire wear, puts added stress on leaf springs and bushings, reduces braking effectiveness on rough road surfaces, and makes loaded trailers significantly harder to control. Capital Diesel provides mobile shock absorber inspection, maintenance, and replacement throughout Sacramento and the surrounding area within a 50-mile radius, diagnosing the problem at your location and resolving it onsite without a shop visit.
Our technicians perform a full shock absorber inspection that covers oil leakage from the shock body, physical damage to the shock housing and mounting points, worn or cracked shock mounts and bushings, excessive travel or bottoming out under load, and uneven bounce across axles. On commercial trucks carrying heavy loads across Sacramento-area roads and highways, shock absorber condition directly affects cargo stability, tire contact with the road surface, and the overall handling envelope of the vehicle. We identify exactly which shocks are failing and replace only what needs replacing, with high-quality components rated for the load capacity and operating conditions of your specific truck.
We service shock absorbers on all major commercial truck brands including Kenworth, Peterbilt, Freightliner, Western Star, Volvo, International, Mack, Hino, and Isuzu, covering both steer axle and drive axle positions. Our mobile units carry common shock absorber components and mounting hardware so most replacements are completed on the first visit at your location. We cover Sacramento and the surrounding area within a 50-mile radius, including West Sacramento, Elk Grove, Roseville, Rocklin, Folsom, Davis, Woodland, Citrus Heights, Rancho Cordova, and North Highlands.
If your truck is bouncing excessively, wearing tires unevenly, or handling poorly under load, do not put off the inspection. Call (916) 949-4882 Monday through Friday, 8am to 5pm, and we will send a diesel mechanic to your location to assess and repair your shock absorbers onsite.
We Inspect the Full Suspension Picture, Not Just the Shocks: Worn shock absorbers rarely fail in isolation. Our technicians inspect the related mounts, bushings, and spring components at the same time to make sure replacing the shocks actually resolves the handling issue and does not leave an underlying problem behind.
High-Quality Replacement Shocks Rated for Your Load: We use commercial-grade shock absorbers rated for the weight class and operating conditions of your specific truck, not generic aftermarket parts that wear out prematurely under heavy loads.
Parts on the Truck for Most Common Replacements: We stock shock absorbers and mounting hardware for common commercial truck configurations on our mobile units so most replacements are completed at your location on the first visit without a parts delay.
Onsite Service Across Sacramento's 50-Mile Radius: Whether your truck is at a yard, a job site, a loading dock, or a truck stop anywhere within 50 miles of Sacramento, we come to you and handle the repair right where the truck sits.
Clear Diagnosis Before Any Work Starts: We inspect both shock positions on each axle, document the findings, and explain exactly what is failing and why before recommending a repair. You know what you are paying for before any parts come off the truck.
All Major Brands and Axle Positions Covered: Our technicians are experienced with shock absorber service on steer axles and drive axles across Kenworth, Peterbilt, Freightliner, Western Star, Volvo, International, Mack, Hino, and Isuzu trucks throughout the Sacramento area.

How do I know if my truck's shock absorbers are failing and need to be replaced?
The most common signs are excessive bouncing or oscillation after hitting a bump, a rough or unstable ride under load, uneven or cupped tire wear patterns, the truck pulling or wandering during braking, and visible oil leakage from the shock body. If you are seeing any of these symptoms on your Sacramento-area route, call (916) 949-4882 and we will inspect the shocks onsite.
Can worn shock absorbers actually damage my tires and brakes?
Yes. Worn shocks allow the suspension to bounce excessively, which reduces the time each tire spends in firm contact with the road surface. This causes cupped or scalloped wear patterns that shorten tire life significantly. It also reduces braking effectiveness on uneven road surfaces because the tires are not consistently contacting the pavement during a stop.
How often should commercial truck shock absorbers be inspected?
Most manufacturers recommend inspecting shock absorbers every 30,000 to 50,000 miles or during each scheduled preventive maintenance visit. Trucks that run heavily loaded routes, off-road job sites, or rough Sacramento-area roads may need more frequent checks due to the increased stress on suspension components.
Do you carry replacement shocks on your mobile unit?
Yes. We stock shock absorbers and related mounting hardware for common commercial truck makes and configurations on our mobile service vehicles. Most replacements are completed at your location on the first visit without waiting on a parts order.
Will replacing the shocks fix my uneven tire wear?
If worn shock absorbers are the primary cause of the uneven wear, replacing them will stop the wear pattern from progressing. However, tires that have already developed cupped or scalloped wear from prolonged shock failure may need to be rotated, balanced, or replaced depending on how severe the damage is. Our technician will assess the tire condition during the shock inspection and let you know what is needed.
