Steering & Suspension Repair in Longmont, CO
When your vehicle starts clunking over bumps, pulling to one side, or riding rougher than it should, the steering and suspension system is almost always involved. At Stonum Automotive, our technicians diagnose and repair every component of the steering and suspension system, shocks, struts, ball joints, tie rods, control arms, sway bar links, wheel bearings, and power steering, across all makes and models. This is not a wait-and-see repair category. The steering and suspension system controls how your vehicle handles, steers, and stops, and problems here grow more dangerous and more expensive the longer you ignore them.
Stonum has been serving Longmont and the surrounding Front Range communities since 2004. Every repair starts with a thorough diagnosis and a written estimate you approve before we begin any work.

Complete Steering & Suspension Repair Services
Stonum covers the full steering and suspension system, every component category, all makes and models, domestic and import.
Shocks & Struts
Shocks and struts are the primary ride-control components. Struts are structural; on most modern vehicles, they also anchor the steering knuckle and directly affect alignment geometry. Worn shocks and struts produce a bouncy ride, nose-dive under braking, and excessive body sway in corners. For an in-depth look at this service, see our dedicated shocks and struts page.
Ball Joints
Ball joints are the pivot points that connect the control arms to the steering knuckles, allowing the wheels to move up and down while also steering side to side. Worn ball joints produce clunking noises and looseness in the wheel. In severe cases, a ball joint can separate, a catastrophic failure that removes steering control. Inspect for suspension play in the correct loaded position.
Tie Rods (Inner and Outer)
Tie rods connect the steering rack to the wheels and transmit steering input. Worn inner or outer tie rods cause loose, vague steering, a tendency to wander, and rapid or uneven tire wear-often flagged first when a wheel alignment shows significant toe misalignment.
Control Arms & Bushings
Control arms connect the suspension to the vehicle frame and guide wheel travel. Rubber bushings at each mounting point isolate vibration and allow controlled movement. Cracked or collapsed bushings produce clunking sounds, poor handling, and accelerated tire wear as wheel geometry shifts out of spec.
Sway Bar Links & Bushings
Sway bar links connect the sway bar to the suspension and limit body roll during cornering. Worn links or bushings are among the most common sources of a rattling or knocking noise over bumps, and they allow excessive lean in turns.
Wheel Bearings
Wheel bearings allow the wheels to rotate smoothly. A failing wheel bearing typically produces a humming or growling noise that changes with vehicle speed and often worsens on turns as load shifts to one side. Left unaddressed, a failed wheel bearing can result in wheel separation.
Power Steering Service
Stonum inspects and services both hydraulic and electric power steering systems, including fluid level and condition, hoses, the pump, and the steering rack. Heavy, stiff, or noisy steering at low speeds is the most common indicator of a power steering problem.
Springs (Coil & Leaf)
Springs support the vehicle’s weight and determine ride height. A broken or sagging spring can make one corner of the vehicle sit noticeably lower than the others and compromise ride quality and handling stability.

Signs Your Steering or Suspension Needs Attention
Clunking, Knocking, or Rattling Noises Over Bumps
The most common suspension complaint. Worn ball joints, sway bar links, control arm bushings, or strut mounts are typical culprits. The noise location- front, rear, left, or right- helps narrow the component.
Vehicle Pulling to One Side
A consistent pull while driving can indicate a worn tie rod, ball joint, or control arm affecting wheel alignment. It can also point to brake issues, so a mechanic should diagnose it rather than assume it.
Rough, Bouncy, or Floaty Ride
Excessive bounce after hitting a bump, or a floating sensation at highway speeds, typically means worn shocks or struts that are no longer dampening road input correctly.
Steering Feels Loose, Vague, or Wandering
If the vehicle needs constant small steering corrections to stay straight, worn tie rods, loose steering rack mounts, or a failing wheel bearing are common causes.
Recognizing any of these symptoms? Steering and suspension problems don’t fix themselves, and they get more expensive the longer you ignore them. Contact Stonum to book your inspection.
How Stonum Diagnoses and Repairs Steering & Suspension Problems
Stonum’s repair process is diagnostic-first. The goal is to identify what is actually wrong before recommending anything-not to replace parts and hope it resolves it.
Step 1: Symptom Review. The technician starts by listening to the driver. Where is the noise? Under what conditions does it appear? Symptom location and conditions narrow the diagnostic focus before the vehicle goes on the lift.
Step 2: Visual Inspection on the Lift, Full undercar inspection covering all suspension components. Technicians check for leaking shocks or struts, cracked or collapsed bushings, broken ball joint and tie rod boots, corrosion, impact damage, and spring sag.
Step 3: Component-by-Component Physical Check. Check each load-bearing component for play and looseness using the correct method. For example, check ball joint play with the suspension loaded, not just with the wheel hanging free. This distinction matters for an accurate diagnosis.
Step 4: Test Drive. A road test confirms the physical findings against the symptoms the driver reported. Some noises appear only under specific conditions, a turn at low speed, a bump at highway speed—and must be verified dynamically before making a repair recommendation.
Step 5: Written Estimate. The customer receives a clear, itemized explanation of what was found and what needs repair, prioritized by safety impact. No work begins without customer authorization. Per Stonum’s commitment to honest service, we don’t recommend repairs that aren’t needed.
Step 6: Repair with Quality Parts. Replacement parts meet or exceed OEM specifications. Stonum’s NAPA affiliation supports consistent parts quality and access.
Step 7: Wheel Alignment After Repair. Any suspension repair that changes wheel geometry- strut replacement, ball joints, tie rods, control arms- is followed by a wheel alignment. Skipping the alignment after a suspension repair leads to rapid tire wear and compromised handling, and Stonum does not skip it.
Step 8: Post-Repair Test Drive. A final road test confirms the repair resolved the symptom, ride quality is correct, and no new issues are present before we return the vehicle.
