For static loading
static loading on one wheel on the front axle will be = 8358.12N
For braking
The load on one wheel at the front axle = 11249.79 N
For cornering
during cornering the loading on one wheel on the front axle is around = 20814.619 N ( inner wheel)
For down hill travel
The loading on one wheel during down hill travel will be = 9029.1

Calculations
for dynamics:
modulus of resilience= 491504.8544 J/m3
Strain
Energy Limit for (Lower/upper) Wishbone = Modulus of resilience × Volume of part
For lower=268.58 J/m3
For upper=134.67 J/m3
............values are lower
