Stabilizer link replacement
Anti-roll-bar links are a common cause of suspension knocking.
Symptoms
- A dull knock over small bumps and in turns that disappears on a smooth road.
What's included
- These slender parts carry loads whenever the body rolls, so they wear before other components. A characteristic symptom is a dull knock over small bumps and in turns that disappears on smooth roads. We check links on a play detector, where a worn joint is immediately apparent. Replacement is relatively simple and inexpensive, but delaying it lets a worn link transmit impacts to the bar and bushes, increasing the repair scope. We replace links in axle pairs and inspect the bushes at the same time. Kyiv roads wear this assembly particularly quickly, so we check links at every suspension inspection.
Additional checks
- Checking the links on a play detector
- Replacement in axle pairs with a check of the anti-roll-bar bushes
Why it matters
Sway bar links are the thinnest part in the assembly, so they wear out before other suspension parts. A broken link passes shocks onto the sway bar itself and its bushings.
More details
Sway bar links are the most common cause of suspension knocking. They're the thinnest part in the design and take the load with every body roll, so they wear out before other parts. The symptom is characteristic: a dull knock over small bumps and in corners that disappears on smooth roads. We check the links on a play detector — a worn ball joint connection is visible right away. Replacement is simple and inexpensive compared to the rest of the suspension, but it shouldn't be put off: a worn link transmits impacts to the sway bar itself and its bushings, which is a different scope of work. We replace them in pairs on the axle and inspect the sway bar bushings at the same time. On Kyiv's roads this part wears out especially fast, so we check the links at every suspension inspection.
