Some car has separate components – springs and shock – while others is combined to become part of a unit that is called the strut. When referring to strut, the portion with a shock is called the strut cartridge.

The strut works the same as when the two main components are separated. The spring on the strut is the one that absorbed the irregularities of the road – uneven surface. The strut cartridge is the one that limits the contraction or expansion of the springs and keeps the spring from excessive bouncing. When you drive your car over the dip the weight of the entire rear end will absorbed by the rear suspension, in this case the strut, when the strut cartridge is faulty it will compressed to its maximum because of the weight of the rear end that it handles, and this will result to a loud thump that you heard coming from rear end.
