Suspension components, including springs and shock absorbers take a pounding daily from potholes, gravel and all manner of dirt and grime, and the occasional piece of debris that drivers see too late to avoid.
Suspension components can be damaged or worn out from years of abuse and if your car is showing any of the following telltale signs it may be time to bring your car into Nolan Motors and we can see if there is a problem
Poor wheel alignment:
The wheels have to be pointed in the right direction (literally) and aligned for toe-in, camber and caster. If they aren’t, your steering won’t be centred when you’re going straight and tire wear will increase. Wheels get knocked out of alignment by potholes and curbs, but getting the wheels aligned won’t fix damaged springs, controls arms or other parts that affect alignment. When you buy new tires, it’s a good idea to have the alignment checked so suspension issues don’t shorten tread life.
When they wear out, you should notice more bouncing after a bump and a whole lot of shaking going on over rough roads because they can’t keep the tires planted on the pavement. Shocks contain fluid that dampens the bouncing, and once they start to leak, performance will deteriorate.
These are what hold the weight of the car, and as they wear they can sag or break. If your car is on level ground but one corner is lower than the others, that’s a sign of a damaged spring. You can measure the height of the corners to confirm your visual cue. You might also hear clunking noises over bumps, and the car may not corner with confidence because a damaged spring can’t control the weight it’s supporting.
These are pivot points that attach the suspension to the wheels, and they absorb some of the shock from up-down movement and rotate as the steering angle changes. You’ll know they need replacing when you can hear them squeaking and creaking, especially when turning. You’ll know you waited too long if a ball joint breaks and suspension parts are dragging on the pavement. A mechanic can tell if they need replacing by the amount of wheel movement they can force by hand or, in some cases, by wear indicators on the ball joints.
These are hinges that hold the wheels to the frame and connect the steering to the wheels, so when you turn one, the other responds. Lower control arm bushings are more prone to wear out on front-wheel-drive cars than on rear-wheel-drive cars. Bushings are rubber and/or metal parts that help absorb shock, and when they wear, they can cause ride and handling problems and accelerate tire wear. So can a bent control arm. Signs of wear include clunks or rattles — because the wheels move back and forth in acceleration and braking — and loose, imprecise steering.
