When Should You Replace Your 4WD Suspension? Signs to Watch For

Your 4WD suspension works hard — whether it's loaded up for a trip or tackling daily bumps and corrugations. Over time, wear and tear takes a toll. But how do you know when it’s time to replace it?

Excessive Bouncing After Bumps

If your vehicle keeps bouncing after hitting a speed bump or pothole, your shocks are no longer controlling movement properly.

Nose Dives When Braking

A clear sign your front shocks are worn. Your 4WD dips forward too much when braking, especially under load.

Rear-End Sag or Uneven Stance

A sagging rear or uneven ride height can point to tired springs — especially if you're regularly carrying heavy loads.

Tyre Wear That Doesn’t Make Sense

Scalloping or inner-edge wear might not be a tyre issue — it’s often caused by worn shocks, poor alignment or bush deterioration.

Clunking, Knocking or Creaking Sounds

Noises when turning, braking or going over bumps could mean failing bushes, worn struts, or loose mounts.

For most 4WDs:

• Shocks: 80,000–100,000km (less if heavily loaded or off-road)
• Springs: Up to 150,000km depending on usage
• Bushes & mounts: Check every 30,000km or annually

If you’re replacing worn factory gear, consider upgrading to something stronger. Tough Dog shocks, coils, and GVM upgrades are designed to handle real-world conditions better than OE parts — and give you a longer lifespan, more comfort, and extra control.

Don’t wait for failure. If your ride feels rough, noisy or unbalanced — it’s time to inspect your suspension. Replacing or upgrading at the right time means better safety, smoother travel, and fewer surprises down the track.
