The major unit on front part of the motor vehicle is front axle. It takes the weight of the front portion of the automobile. It gives steering facility and absorbs shocks. The weight of the front part of the vehicle is transmitted to the road surface through front wheels by the front axle of a vehic…...

Rear-axle transmits power from the differential to the wheels so that vehicle may move. Rear-axle is not a single piece but it is in two parts that are connected by the differential.  Each part of the rear axle is called the half shaft. The outer end of the rear axle carries the whee…...

The construction of the shaft bearings is important, as this holds the complete weight of the propeller shafts. There are two main types of bearings- the full case bearing located at the stern, and the half case bearing located at the other positions. The full casing provides a complete bea…...

The marine propeller shaft is divided into three main components-the thrust shaft, intermediate shaft(s), and tail shaft. The thrust shaft is the primary shaft emerging out of the engine. It directly receives the rotational motion from the crankshaft and rotates at the maximum velocity in high-speed…...

Stern tube arrangement refers to the manner in which the tail shaft is borne by the stern tube that is located at the aft of the vessel. The stern tube is a hollow, horizontal tube that serves as the primary connection between the propeller shaft and the rest of the vessel. Attached to the…...

Today’s vehicles feature a front suspension system that use upper and lower control arms to attach the wheel hub to your vehicle, or else use a MacPherson strut and one control arm to mount the wheel hub. The wheel hubs, on which your wheels and tires are mounted, are attached to the outer ends of e…...

A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. Couplings do not normally allow disconnection of shafts during operation, however there are torque limiting couplings which can slip or disconnect when some torque limit is exceed…...

Couplings fall in two main categories: Rigid Couplings and flexible Couplings. we are going to make a comparison of the main differences between the rigid and flexible couplings. Rigid couplings These types of couplings provide a solid connection between two shafts, high precision and torqu…...

A gear is a rotating machine part having cut teeth, which mesh with another toothed part in order to transmit torque, in most cases with teeth on the one gear being of identical shape, and often also with that shape on the other gear.  Two or more gears working in tandem are called a t…...

The ball joints allow your car's front end to move up and down and left to right as well as turn for steering. Ball joints usually last a long time, but they can wear down over time or from extreme driving conditions. Here's how to check your ball joints: Listen to the suspension Listen to …...

Universal joint connects two rotating shaft allowing freedom of movement in all direction. They are widely used in drive shaft applications and situations where shaft force needs to be transmitted through various angles.  Multiple universal joints can be employed to provide relatively …...

Understanding U and CV joints are essential for off-roading vehicles. They are the main way any significant ground clearance can be achieved on a vehicle since they allow for greater driveline angles than any other form of torque transference.  There are several places you can find U o…...

A vehicle's drive shaft--the rotating object located between the differentials and gear box--helps it switch from idle to drive; without it, a vehicle would never move.  Usually, a drive shaft does not fail instantaneously, and deterioration happens over time. Accordingly, if drive sha…...

what U-joint should you go with? And what, exactly, is the job of a U-joint? Well, a U-joint is designed to not only allow the driveshaft to move in its arc without binding, but it is also the weak link.  Most likely your Jeep came factory with a U-joint in your driveshaft. Right away,…...

Drive shaft inspection should be carried out at regular intervals and it would be reasonable to co-ordinate this with the maintenance work on other Vehicle parts.  The maintenance intervals mentioned in the following section are only recommendations because maintenance intervals genera…...

While the driveline is designed for the life of a truck, due to harsh environments and often severe duty cycles, there are instances where drivelines need to be serviced and worn components replaced. It is imperative to follow inspection procedures to check splines and joints for possible …...

To measure driveshaft angles and U-joint angles, start by lifting the vehicle either on a drive on style vehicle lift, or an axle contact style. This will keep the suspension under load and allow for correct measurement. On your U-joints, the working angles may differ no more than 0.5° of e…...

Drive shafts and U-joints provide an efficient and durable means of transferring engine torque to the drive axles. U-joints allow drive axles to move up and down with the suspension while the shaft is rotating so power can be transmitted even when a drive shaft is not at the same angle as its connec…...

Since most technicians today opt to replace the entire shaft rather than individual CV joints, here are some suggestions that can help avoid problems later: Make sure you have the right replacement CV joint or shaft for the vehicle. Chrysler FWD and Honda use CV joints from various supplier…...

Disassembling a constant velocity joint is not difficult if you know how. The first trick is getting the CV joint off the end of the prop shafts. Some joints just pull off while others are held with a snap ring or lock ring which must first be released. Once the joint is off, it can be d…...
