Alright, let’s talk wheel bearings. Not the flashiest part of your car, but when they go bad, you’ll know about it. Had a Mazda Axela in last week, owner reckoned it was just a tyre noise. Turned out the front left bearing was cooked. Sounded like a freight train once we got it up on the hoist.
Wheel bearings cop a hiding in everyday NZ driving, especially around Hamilton. Between all the potholes on the back roads, those big kerbs in town, and the constant stop-start traffic near The Base or over at Chartwell, it’s no wonder they wear out quicker than you’d think.
What Do Wheel Bearings Actually Do?
In simple terms, they help your wheels spin freely while supporting the car’s weight. They’re tucked in behind your brake discs and need to stay properly greased and sealed. If that seal breaks, from water, dirt or just old age, the bearing dries out and wears down.
And once they start to go, they don’t get better on their own. You’ll get humming, growling, maybe a bit of play in the steering, and over time it can even affect your brakes or tyres.
Tips to Keep Them Going
1. Avoid Hard Knocks
Potholes, speed bumps, and smashing up steep driveways at pace, all of that rattles your suspension and bearings. Seen plenty of older Subarus and Honda Fits with worn bearings just from rough commutes down uneven roads. Take it easy, especially if your driveway’s got a sharp lip or you live in a hilly area like Dinsdale or Flagstaff.
2. Don’t Overload Your Car
Loading up the back of your Toyota Estima for a family holiday? That extra weight adds pressure to your bearings. Same goes for utes carting heavy gear without upgraded suspension. If your car’s dragging lower than usual, your bearings are probably taking more strain than they should.
3. Listen for Noises
You know your car better than anyone. If it starts sounding like a dull roar or you hear a rhythmic hum that changes with speed, get it checked. We had a bloke with a Nissan X-Trail reckon it was just tyre wear, but the rear wheel bearing was on its last legs. Left too long, and it would’ve needed a hub replacement too. Bit more costly than just swapping the bearing.
4. Get Regular Checks During a WOF or Service
Honestly, most drivers don’t even realise they’ve got a bearing issue until it fails a WOF. At Grimmer Motors, we check them as part of your regular car service in Hamilton. Better to catch it early than have it leave you stranded out in the middle of nowhere or halfway to Taupo.
How NZ Weather Plays a Part
Wet winters and hot, dry summers in the Waikato? Not great for rubber seals. Water gets in during soggy months, then everything bakes dry and brittle in summer. That mix is brutal on bearings, especially on older vehicles or imports where the seals are already a bit tired.
