Drive Shaft Repair

The drive shaft is an important element of the transmission. It is responsible for transmitting torque from the gearbox to the axle, so the stability of its operation directly affects the functioning of the chassis.

Signs of a malfunction that require you to contact a repair shop

Knock when driving
Grinding noise when the car is moving
Vibrations in the car body while driving
Sounds like humming and whistling.

Repairing a driveshaft is a fairly complex process, so it should only be done by professionals.

Work that is possible after diagnostics

Replacing crosspieces, changing the method of fastening crosspieces, replacing forks for installing crosspieces.
Changing the length of the driveshaft. Possible shortening or lengthening. When extended, the pipe changes completely.
Replacement of outboard bearings.
Replacement of spline connections.
Restoration of mounting holes for bearings. The work is carried out using welding or using a polymer coating of worked surfaces.
Straightening of deformed pipes using a hydraulic press. They are necessarily tested for their ability to maintain a given torque.
Cardan calibration. It is necessary to eliminate the imbalance not only after dismantling and installing a new part; this may be necessary when the plate is torn off or after hitting an obstacle.

After installing all the parts, it is necessary to test drive the car and check the functionality of the driveshaft. If everything works properly, then you can carry out maintenance on the propeller shaft and continue to operate the vehicle.

In order to extend the life of the shaft it is necessary:

systematically check the bolts of flange connections for immobility;
tighten connections as necessary;
periodically check whether the bearing cups are secured with retaining rings;
check the condition of the grease fittings necessary for lubrication of the crosspieces;
regularly check the driveshaft for damage to the coating, wear of the polymer coating, and malfunctions of the outboard bearing.

Burning Rubber Smell

The most common reason for a car making a burning rubber smell is because of a serpentine belt that slipped. The slipped belt commonly starts touching a hot component, and since it's made of rubber, it causes a burning rubber smell.

Overheating internal components: Overheating internal components can cause a burning rubber smell due to the breakdown of rubber hoses and belts. When the engine or other components become too hot, it can cause rubber hoses and belts to deteriorate, releasing a strong odor.
Slipping serpentine belt: A slipping serpentine belt can cause a burning rubber smell in a car due to friction and overheating. If the belt is loose, and slips, it can generate heat and friction, leading to a burning rubber smell as the belt deteriorates.
Failed tensioner: A failed tensioner can cause a burning rubber smell in a car due to the increased friction and heat generated by a loose or misaligned serpentine belt. The tensioner maintains the proper tension of the serpentine belt, if it fails, it'll generate extra friction, causing the burning smell.
Bent suspension components: Bent suspension components can cause a burning rubber smell in a car due to the misalignment and increased friction between the tires and the road. This can lead to a burning rubber smell as the tires deteriorate.
Friction on the timing cover: Friction on the timing cover can cause a burning rubber smell in a car due to the rubbing of the timing belt or chain against the cover. This friction can generate heat and cause the belt or chain to deteriorate, emitting a burning rubber smell.
Faulty drive shaft center support bearing: The drive shaft center support bearing supports the drive shaft in its housing and allows it to rotate smoothly. If the bearing is faulty, it can cause the drive shaft to vibrate or wobble, leading to friction between the drive shaft and surrounding components.

It's common to notice a burnt rubber smell coming from your car. Often, it is not tire-related; the odor might come from rubber contact with a hot engine or exhaust pipe instead. Hence, many of your car's rubber parts, such as coolant hoses, steering hoses, timing belts, and accessory drive belts, might have something to do with it.

Acting early is crucial since rubber can deteriorate under high heat and affect related parts.
