Wind is a load, not weather
Kansas is among the windiest states and the wind is not seasonal. On open highway a car is being pushed sideways continuously and the driver is correcting for it continuously.
That is a genuine mechanical load and it is asymmetric.
- Tyres wear on one shoulder more than the pattern predicts, because the car is running at a small permanent slip angle.
- The steering rack and tie rod ends take constant small inputs under lateral load rather than the straight-then-turn pattern of city driving.
- Suspension bushings are loaded to one side for hours at a time.
- Fuel consumption rises, which is the part everyone notices and the least important.
It is why a Kansas highway car can need an alignment without ever having hit anything, and why checking alignment on a schedule is worth more here than in a state where it is only a post-impact repair.
Distance, and what it wears
Long sustained running at speed is gentle on brakes and hard on everything that rotates. Hours at load accumulate on wheel bearings, constant-velocity joints, tyres and the drivetrain.
The two noises worth learning:
- A hum or growl that rises with road speed and ignores engine speed. Change gear at a steady speed; if the noise tracks the speedometer it is rotational. Rotate the tyres front to back before condemning a bearing, because cupped tyres sound almost identical and the test is free.
- A rhythmic click on full lock at low speed, which is an outer constant-velocity joint.
Brakes, meanwhile, can corrode before they wear. A rotor with plenty of thickness left can still be pitted and scaled enough to need replacing, and caliper slides can seize without ever having worked hard.
Hail and severe storms
Kansas is well inside the region that gets the most damaging hail in the country. The panels get claimed; the parts that fail afterwards are the lenses and the fins.
Hail cracks a polycarbonate lamp lens without shattering it. Water gets in, the reflector corrodes, the connector oxidises, and the assembly fails properly weeks later when nobody connects it to the storm. It also flattens condenser and radiator fins, reducing the surface available to reject heat.
Look at the lenses in daylight with the lamps on, and look through the grille at the condenser, after any significant storm.
Gravel counties
Away from the interstates a large share of county roads are unpaved, and gravel adds abrasion to everything. Air filters load fast, grit is thrown at every boot, and washboard works dampers at high frequency for miles at a time — which fades them in a way a single impact never does.
A very wide temperature range
Kansas moves a long way between January and July and often a long way within one day. That works every seal and gasket in the vehicle, moves tyre pressures between morning and afternoon, and gives batteries the worst of both ends: summer heat runs the clock that destroys them, winter cold reveals the damage.
Replace a battery on age rather than on failure. Four summers here is a full life.
