  • Then there’s the torque-vectoring differential, the most advanced of them all.
  • Whether you’re turning a corner or rock climbing, the wheels will always spin equal amounts.
  • Also, if any of these symptoms go unnoticed, the differential will break down completely, leading to serious accidents.
  • To put it another way, the differential divides the available power across the wheels, allowing them to revolve at different speeds as a result of this split.
  • It’s worth noting that just because your axle is damaged doesn’t mean it’s bad.
