Toyota 4Runner Crankshafts

A crankshaft is one of the fundamental components of the internal combustion engine. It is attached to the pistons utilizing connecting rods and is used to transform the reciprocating motion of the pistons into rotations. By design, the engine has only one crankshaft that is typically located in a lower section of the engine known as the crankcase. The crankshaft is held by means of the bearings, which number mainly depends on the engine power and the number of cylinders. The shaft is sealed inside the crankcase by special rings from both ends to prevent the oil from leaking. These seals, however, are comparably weak and are prone to deterioration over time. It is a common problem shared by many vehicles, including the Toyota 4Runner.

Whereas a worn-out seal only forces you to check the oil level after every trip and spend money on the oil to refill, an impaired crankshaft can cause severe damage to your SUV. Therefore, urgent measures should be taken with the use of high-quality replacement parts.
