You’ve got the stance, the clearance, and maybe even a bit of swagger in the driveway. The rig looks tough, sits proud, and you’re already planning your next off-road escape. But before you roll into the bush grinning ear to ear, take a breath.
There’s one more step that often gets skipped—a proper post-install suspension inspection. Ignore it, and your setup might go from weekend-ready to workshop-bound in no time. Imagine getting a DMax lift kit but not able to maximise its benefits due to improper installation.
1. Start with a Visual Walkaround—But Know What You’re Looking At
Before you hit the road, get under the rig and have a proper squiz. Check that everything is sitting where it should be and nothing looks out of place or under strain. Pay close attention to the following areas:
- Control arms, especially upper arms if changed
- Strut towers and coil seats
- Sway bar links and bushings
- Shock mounts, top and bottom
- Brake lines and brackets
Give every bolt a once-over. Are they snug? Anything that looks like they’ve had a lazy hand on the spanner should be flagged for torquing. Also, look for rubbing. If coils are touching, if shocks are sitting at weird angles, or if the sway bar’s out of whack, something’s not right.
Symmetry also matters. If one side’s got noticeably more clearance than the other, it could point to uneven preload or a poor install.
2. Torque It Like You Mean It
No one likes surprises mid-track, especially the kind that ends with recovery boards and a bruised ego. Every bolt that was touched during the install needs to be torqued to spec. After about 100–200 kilometres of driving, things settle. That’s when it’s time to grab the torque wrench and get cracking.
Check your lift kit manual or the manufacturer’s website for exact figures. If you’re ever unsure, call your installer or supplier. Key areas to re-torque include:
- Upper and lower control arms
- Shock absorber top and bottom mounts
- Leaf spring bolts (for the ute crowd)
- Sway bar brackets
3. Listen to Your Suspension—Literally
Silence is golden, but it’s also revealing. After your first proper drive, take five minutes to listen. Turn down the music, open a window, and roll slowly over uneven ground. If you hear clunks, squeaks, groans, or rubbing sounds, something needs attention. It might just be a bracket out of alignment or a dry bush. Or, it could be a loose mount that’s begging for a retorque. Either way, catch it now and save yourself the hassle later.
4. Double-Check Alignment and Steering Geometry
Once you’ve added height, your suspension geometry changes. The angle of the wheels, the tracking of your tyres, and how your steering wheel sits—it’s all affected. Even if it feels mostly okay, a minor misalignment can:
- Burn through tyres faster than you’d believe
- Make the steering wheel sit off-centre
- Cause the vehicle to wander or pull
Do a simple driveway check with these questions:
- Is the steering wheel straight when driving forward?
- Is there any noticeable pull to one side?
- Are your tyres showing early feathering?
If the answer to any of those is yes, it’s time for a proper 4-wheel alignment, ideally from a shop that understands lifted vehicles.
5. Suspension Travel Test—Articulate It Safely
This one’s a bit of fun but highly telling. Park one wheel on a rock, log, or ramp (nothing sketchy, yeah?) and check how the suspension flexes. You’re looking for smooth articulation without anything binding, overextending, or shifting oddly. Use this flex test to spot:
- Overstretched brake lines or ABS wires
- Dislodged or misaligned coils
- Shocks topping or bottoming out
- Bump stops doing their job evenly
6. Inspect Brake Lines, ABS Wires & Hoses
When you lift a rig, those brake lines and ABS wires now need to reach further, especially when the suspension droops. Check for:
- Enough slack in brake lines at full articulation
- ABS wires safely routed, not chafing or rubbing
- Hoses kept clear of heat—exhaust pipes are notorious culprits
If it’s tight now, imagine it when you’re flexed out mid-river crossing. If needed, install relocation brackets or braided lines to play it safe.
7. Suspension Bushing Check—They’re the Unsung Heroes
Often overlooked, bushings are what cushion your suspension parts. After a lift, the geometry changes, and the bushings might be taking extra strain they weren’t built for. Look for:
- Visible cracks or dry rot
- Too much movement when pushing/pulling control arms
- Annoying squeaks during low-speed travel
If they’re flogged out, it’s worth considering polyurethane upgrades. They’re tougher and they last longer, which is especially ideal under Aussie conditions.
8. Measure Ride Height and Track Your Settling
Your new suspension will settle—that’s just how springs work. But knowing how much it settles helps catch any early issues.
Measure from the centre of the wheel up to the edge of the guard, on flat ground, with equal tyre pressure. Write it down, both front and rear. Re-check after a couple of weeks. If one side sags more than the other, you might have:
- Uneven spring preload
- Misinstalled components
- Failing springs or shocks
9. Post-Install Maintenance Schedule—Set It and Don’t Forget It
You’re not done just because the lift’s in. Regular upkeep is what keeps your ride safe and your weekends worry-free. Here’s a basic maintenance rhythm to follow:
- Re-torque critical bolts after 200 km, then again after 1,000 km
- Monthly inspection of brackets, bushings, and mounts
- Check wheel alignment every 6 months or after a rough trip
- Inspect for leaks, sagging, or changes in ride quality
Lifted and Ready—But Don’t Skip the Homework
There’s nothing quite like the feeling of a freshly lifted rig. It’s like putting on a good pair of boots—you feel taller, stronger, and ready to take on the elements. But boots need breaking in, and so does a new suspension setup.
Inspect it properly, maintain it routinely, and pay attention to the little things before they turn into big ones. That’s how you turn a lift kit into a long-term upgrade, not just a weekend mod.
