Mark Jackson Automotive
Potholes, speed humps and sandy beach tracks all take their toll on your car suspension. If your ride feels off, Mark Jackson Automotive can find out why and get it sorted.
From the Gold Coast Highway to the backroads out west, these roads throw a lot at your vehicle, and suspension components wear out quietly until suddenly they don’t. A clunk over speed humps, a car that pulls to one side, or a ride that’s gone bouncier than usual are all signs it’s time for a check. Our Southport workshop has been handling suspension repairs for Gold Coast drivers since 1989, and suspension checks are a key part of our car servicing.
Your car should settle within a bounce or two after a bump. If it keeps bobbing longer than that, your shocks are probably on the way out.
Bald patches and wavy, cupped tread — both point to suspension geometry that's shifted, leaving your tyres sitting unevenly on the road.
If your car drifts left or right on a straight, flat road, that's not something to ignore. It could be your suspension, or it could be your alignment. Either way, get it checked.
A clunk over speed humps. A knock through corners. A squeak at low speed. All of these usually trace back to worn bushings, ball joints or mounts.
Light braking shouldn't send the front of your car diving. If it does, your struts have likely had enough.
Stand behind the car and take a look. One side lower than the other usually means a sagging spring, and it won't fix itself.
Most suspension problems give you a clue before they become a safety issue. Here’s how common symptoms line up with the parts we usually find worn. A proper inspection is the only way to be sure.
What you notice | What’s usually worn |
Keeps bouncing after a bump | Shock absorbers or struts |
Front dips hard when you brake | Front struts or shock absorbers |
Clunk over speed humps | Sway bar links, bushings or strut top mounts |
Knock or creak when turning slowly | Ball joints or strut top mounts |
One corner sitting lower | Sagging or broken coil spring |
Cupped, scalloped tyre tread | Worn shock absorbers |
Tyres wearing on the inner or outer edge | Wheel alignment, often thrown out by worn bushings or ball joints |
Steering feels loose or vague | Ball joints, tie rod ends or control arm bushings |
Oily film on the shock body | Leaking shock absorber |
Springs carry the weight of your car and cushion the big hits such as potholes and speed humps. Over the years, they sag or crack, and when they do, ride height and comfort both suffer.
Shocks are what stop your car from bouncing after a bump. Once they wear out, every pothole turns into a longer, wobblier ride than it needs to be.
Struts do two jobs at once: absorbing shock and holding up part of the car’s structure. Most Gold Coast vehicles run struts on the front axle, where they’re doing a lot of the work in how the car steers and holds a line.
These parts connect your wheels to the rest of the suspension and let everything move the way it’s meant to. Wear here shows up as play in the steering, knocking noises, or handling that just feels loose.
Sway bars stop your car from leaning too far in corners. When the links wear out, you’ll usually hear it before you feel it, a clunk on rough roads or through tight turns.
Speed humps outside every shopping centre, sandy access roads near the beach, and winding routes through the hinterland — all put extra strain on suspension components. The heat doesn't help either; it dries out rubber bushings faster than a cooler climate would. None of this means your suspension is doomed, but it does mean regular checks matter more here than in most parts of the country.
Not everything worn needs replacing straight away. Sometimes a repair or adjustment is all it takes. Other times, replacement is the better call, especially if a part's likely to fail again soon regardless. We'll talk you through the options and let you decide what fits your budget and your car.
We work on hatchbacks, utes, 4WDs and family SUVs. Each of them carries weight differently and handles differently, so each suspension job gets set up around the actual vehicle, not a generic checklist.
Utes and 4WDs have the hardest life on the Gold Coast. Towing a boat or caravan, carrying a loaded tray, or running sand tracks along the coast all push springs and shocks harder than daily driving does. The usual signs are:
1. The rear sitting low when loaded.
2. A float or wallow at highway speed.
3. The front going light when towing
If that sounds familiar, we'll check whether your springs and shocks still suit how the vehicle is actually used, and recommend heavier-duty replacements if they don't. For servicing, steering and everything else your 4WD needs, see our 4WD mechanic Gold Coast page.
Replacing steering or suspension parts can change your wheel alignment. Worn suspension can also be why the alignment keeps drifting out in the first place. If your tyres are wearing unevenly or the car pulls after suspension work, ask about a wheel alignment while the car's already with us. It protects your new parts and your tyres.
Mark Jackson Automotive has industry experience dating back to 1973 and has been serving the Gold Coast from our Southport workshop since 1989. We'll only replace what's actually needed and explain everything clearly, so you know exactly what you're paying for. If your suspension needs work, we'll tell you straight, and we'll do the job right. Our supplier relationships go back more than 35 years, which helps us source quality suspension parts at a fair price.
If your car’s bouncier than a trampoline, pulls to one side, or clunks over bumps, your suspension’s trying to tell you something. Uneven tyre wear is another giveaway. When in doubt, bring it in — we’ll have a listen and a look.
It depends on what’s worn and what your car needs — a bushing swap is a different job from full struts. We’ll inspect first and give you a straight-up quote before we touch a thing. No surprises, no upsells.
As a rule of thumb, get it checked every 20,000km or once a year — sooner if you’ve been hitting potholes, sandy tracks, or speed humps as they owe you money.
Yes — worn suspension affects braking, handling and tyre grip, so it’s a genuine safety issue, not just a comfort one. It’s also checked as part of a roadworthy certificate in Gold Coast, so if you’re booking a RWC with us, we’ll flag it either way.
Yes. We inspect and repair suspension on 4WDs, utes and SUVs, including vehicles that tow or carry heavy loads regularly. We’ll check whether the springs and shocks still suit how you use the vehicle.
Often, yes. Replacing suspension or steering parts can change your alignment. We’ll let you know if yours needs it.
