Study Notes
- A driveshaft transmits engine torque from transmission to rear axle or drive wheels.
- Most driveshafts are made of hollow steel tubing, but some use aluminum or composite materials.
- Driveshafts are balanced and must have working angles of 1/2 to 3 degrees for optimal performance.
- Universal joints are used at both ends of a driveshaft to allow flexibility and torque transfer.
- Double-Cardan U-joints are used to reduce driveline-induced vibrations.
- Constant velocity joints (CV joints) are designed to rotate without changing speed.
- Rzeppa joint is a type of CV joint that can function at angles up to 40 degrees.
- Outer CV joints are fixed joints that allow up to 40 degrees of movement and transmit engine torque to front wheels.
- The protective outer flexible boot of outer CV joints can be easily damaged by road hazards.
- Replacement driveshafts are usually identified by series of U-joints and center-to-center distance between U-joints.
- CV joints connect the transaxle to the drive axle shaft.
- Inner CV joints allow for up and down movement and changing length during suspension travel.
- Unequal-length half shafts can cause torque steer.
- CV joint boots must be flexible and strong to avoid damage.
- There are four types of boot materials used over CV joints.
- Boot seals should be inspected regularly and replaced if damaged.
- CV joints require special moly grease.
- The exact grease to use depends on the type of joint, location, and boot material.
- Inner CV boots can be damaged by high temperatures and engine oil leaks.
- Dampener weights are used to dampen out certain drive line vibrations.
