Your suspension does two jobs. It keeps the tyres pressed against the road, and it keeps the cabin comfortable over bumps. When it wears out, both jobs suffer. The car does not stop as well, and it does not hold a line in the wet the way it used to.
Suspension wear happens slowly, so most drivers adapt to it without noticing. The car feels a bit softer, a bit floatier, a bit noisier over the bumps. Then you get into a car with good suspension and the difference is obvious. The good news is that worn suspension gives clear signs once you know what to look for.
The suspension is made up of springs, shock absorbers or struts, and a set of bushes and joints that connect everything to the wheel and the chassis. The springs hold the car up and absorb the big hits. The shock absorbers control the springs, stopping them from bouncing the car up and down after a bump. The bushes and joints let the suspension move while keeping the wheel pointing the right way.
If the nose of the car dives down when you brake, the body leans over in corners, or the back squats under acceleration, the shock absorbers are likely worn. A good shock keeps the body level through all of that. When they are gone, the body moves around more, and that extra movement adds to the stopping distance and makes the car feel unstable. It is one of the clearest signs the suspension needs attention.
Push down on a corner of the car and let go. It should come back up and settle. If it bounces more than once, the shock absorber has lost its damping. On the road, that shows up as a floaty feeling, where the car keeps moving after the bump has passed. It is uncomfortable, and it keeps the tyres in less contact with the road, which is the real problem.
A knock or a clunk over bumps or when you turn usually means a worn joint or bush. The suspension has rubber bushes that absorb the small movements and keep things quiet. They crack and perish with age, and once they are gone the metal parts knock against each other. Common culprits are control arm bushes, sway bar links, and ball joints. We cover all of these in our steering and suspension service.
Worn suspension changes how the tyre sits on the road, and the tyre wears to match. If the inside or outside edge of the tyre is wearing faster than the rest, the alignment is out, and a worn suspension part is often the reason. A tyre that wears out quickly on one side is a sign worth investigating before you fit a new set, because the new set will wear the same way. Read our guide on when to replace your tyres for what else to look for.
If the car pulls to one side, or the steering feels vague and wanders across the lane, the suspension or the steering is not holding the wheel where it should. A worn ball joint or tie rod end lets the wheel move around more than it should. It can also be a sign the wheel alignment is out, which often follows a suspension repair.
Worn suspension is not only a ride quality issue. The shock absorbers are what keep the tyre pressed against the road. If the tyre is bouncing instead of holding contact, the brakes have less grip and the car takes longer to stop. In the wet, a tyre that is not planted on the road is a tyre that aquaplanes sooner. Good suspension is a safety item.
We put the car on the hoist and check the shock absorbers for leaks, the bushes for cracks, and the joints for play. We look at the springs, the strut mounts, and the sway bar links. If the tyres show uneven wear, we check the alignment as well. Once we know what is worn, we give you a written quote before any work starts. If you are in Moorabbin or nearby, bring it in.
Yes. Replacing one shock absorber on an axle and leaving the other leaves the car unbalanced, because the new one is much stiffer than the worn one. It affects the handling and the braking. We replace them in pairs across an axle, and we use parts matched to your car. A suspension job often ends with a wheel alignment, because the new parts change the geometry.
There is no fixed interval, because it depends on the roads you drive and how the car is used. Shock absorbers often need attention somewhere past 80,000 kilometres, and bushes and joints last longer but do perish with age. An older car that has never had suspension work is the one most likely to need it. We can look at the history and tell you what is due.
If your car feels different over bumps or you have noticed any of these signs, call 0481 797 861 or send us your details. We will check the suspension and give you a quote before any work starts.
Our Moorabbin workshop is open to talk through your service or repair and give you a quote before any work starts.
