Suspension, Shocks & Struts

A clunk over bumps that was not there six months ago. The vehicle drifts right on Highway 97 even though the road is flat. Front tires wearing on the inside edge at twice the rate of the outside. These are suspension problems, and they get worse the longer you wait.

We replaced the front struts on a 2015 Outback last month that the owner had been putting off for two years. By the time he brought it in, both front tires had cupped so badly they needed replacing too. The struts alone would have been $780 installed. Adding two tires brought the bill to $1,340. Had he come in when the bounce first started, he would have saved the tires entirely.

Shock absorbers and struts wear gradually enough that most drivers adapt without realizing it. The vehicle bounces a little more. Body lean in turns increases by a degree or two each year. Braking distances grow longer. None of it happens overnight, so the change feels normal until you ride in someone else's car and realize how far off yours has drifted. We test damper performance on the hoist and during a road test. Oil weeping from the shock body is an obvious sign, but reduced damping happens well before any visible leak.

Ball joints matter more than most drivers realize. A ball joint connects the wheel carrier to the control arm and allows the wheel to pivot when you steer. When a ball joint develops play, you get a clunk over bumps and vague steering feel. When one fails completely, the wheel folds under the vehicle. That is not an exaggeration. We see photos from tow truck drivers showing exactly that scenario, and it happens on vehicles that passed a quick visual inspection at a tire shop three months earlier. Proper ball joint testing requires loading and unloading the suspension to measure actual play with a dial indicator. A wiggle test by hand is not enough on most modern designs.

Tie rod ends transmit your steering input from the rack to the wheels. Worn tie rods add dead play to the steering and throw alignment angles off, which eats tires. Control arm bushings crack and separate over time, especially the rubber types exposed to Kelowna's temperature swings between summer heat and winter cold. Sway bar end links are one of the most common clunk sources we see. They are inexpensive to replace ($120 to $180 per pair installed on most vehicles) and eliminating that annoying knock over every bump makes a noticeable difference in how the vehicle feels.

Kelowna roads are harder on suspension than flat-terrain cities. The hills, the frost heaves that show up every spring on Lakeshore and Gordon, the potholes along the Connector, and the gravel logging roads if you head into the backcountry. Trucks and SUVs that tow boats to the lake all summer wear rear shocks and leaf spring bushings faster than the factory service interval suggests. We see it regularly and adjust our inspection focus based on how the vehicle is actually used.

Alignment ties directly into suspension condition. Worn ball joints, tie rod ends, or control arm bushings shift the wheel angles beyond what an alignment machine can correct. We check alignment after any suspension component replacement and recommend an annual alignment check as general practice. Our four-wheel computerized alignment measures camber, caster, and toe on all four wheels and compares to manufacturer specs for your exact model.

If your vehicle clunks, wanders, bounces, or wears tires unevenly, call (250) 861-4354. We will put it on the hoist and tell you exactly what is worn and what it costs to fix.
