The drive shaft is the most irreplaceable spare part of any all-wheel or rear-wheel drive car. The function of the drive shaft is considered the transmission of torque from one unit to another. Therefore, in the manufacture of drive shaft and the drive gear it is necessary to consider all the conditions of functioning. The design of the drive shaft comprises two hinges, which are connected with each other by a movable splined connection. Drive shafts and drive gears get often disbalanced. Disbalance is a quite dangerous phenomenon that affects all of the rotating mechanisms, as well as drive transmission.

The first sign of disbalance is considered the raising of vibrations, which can increase as well as decline. It can cause the auxiliary load on the transmission parts associated with the drive shaft, fact that can reduce their service life. The parts with the highest wear out possibilities are the bearing flange, the shank reduction gear and the variable gear box. The main causes of disbalance: the manufacturing inaccuracy of some parts of the drive shaft, the diversity of the part`s material and its non-uniform density, the presence of gaps in the joints of the parts and their assembly mismatch, inaccurate alignment of mating parts, shaft deformation under mechanical and thermal processing, and so on.

If you need to replace the drive shaft, do not waste time for shopping or repair shops; you will not only lose time, but also significantly overpay for the necessary part. It is better to go to our online store. We offer to our customers a wide range of drive shafts for any car brand. Order the necessary detail at an affordable price. And we will make sure that the delivery is carried out in a short time. Apart from drive shaft, you can also purchase other automobile parts, for example, power shaft or camshaft.

What you need to know about propshaft replacement: lifetime limits, common defects and their signs, tips and recommendations

Manufacturers don’t limit propshaft service life by certain terms. The component is replaced if necessary.

Component defects are its deformation, disbalance, fixations loosening and also abrasive wear, corrosion and mechanical damages of the universal-joint cross, movable splineways, bearing, bushing.

You can define that the propshaft requires diagnostics by its vibration during engine operation, by oil leakage stains in places of connection of the gearbox and front propshaft part, by rattling at gear shifting. Sometimes rattling sound also appears at accelerator pedal pressing.

Precise diagnostics of component condition is performed at a service station applying high-technology equipment. Moreover, the propshaft is inspected having set the car onto a lifting platform. Need of component replacement is pointed by deformation, dents, damaged or worn-out propshaft joint bearings, free movement of universal-joint crosses and center (hanger) bearing.

Rear propshaft replacement is performed only in service station conditions because it often takes complicated balancing adjustment after new detail installation. At a service station the car is set onto a lifting platform or a service pit. Then they mark the location of the elements relatively to one another and location of the rear universal joint yoke relatively to the final drive pinion flange. Then unscrew the nuts which fixate the shaft to the axle flange and nuts of the retainer of the rubber cushion of the center bearing, after that the shaft is removed from the gearbox splineways. A new component is installed and assembling is performed. Replacement of the front propshaft is performed in a similar manner.
