Rear Axle Assembly

What is a Rear axle?

The rear axle assembly is basically a large and heavy piece of steel and iron that receives rotational power through the drive shaft from the engine and transmission. It then uses this power to propel the vehicle by converting the said rotational force into linear motion by turning the axles, tires and wheels. In most cases, the rear axle rotates with the vehicle’s wheels. It generally comes in two halves known as half shafts which are connected by the differential.Not all rear axles are the same as they differ according to support and mounting methods.

There are generally considered to be three types of rear axle –

Semi-Floating Axle: These kinds of axles are mostly used for cars, SUVs and mid-size trucks. It connects the wheel to the flange on the axle shaft and holds it securely. One bearing goes inside the axle casing and the other supports the axle shaft. Since it has two bearings, semi-float axles tend to be larger than its counterparts so that it can produce the same amount of torque.

Three-Quarter Floating Axle : This Axle is more complex than the semi floating axle and also more reliable. It maintains the wheel alignment and handles side thrust and driving torque.

Full-Floating Axle: These axle types are generally used by larger vehicles such as heavy-duty trucks. As its name indicates, a full-floating axle typically floats in place and maintains its position with the help of its two bearings. It’s designed to transmit only the driving torque

Signs of a Failing Rear Axle Assembly–

There are majorly four easy signs which will help you identify a rear axle assembly that is about to fail –
 

1.Weird noises– The gears and bearings in the axle system will most likely create a cacophony of whining and growling noises if there are problems within the rear axle assembly. Noises are the most common warning sign that the rear axle is headed south. Excessive clearance between the gears can also cause possible clunking noises that in most cases are clearly evident only when the vehicle is put into gear.

2.Fluid leaks– If you notice fluid accumulation under the rear of your vehicle, you may have a leaking axle seal or gasket. In these cases, you need to immediately take your vehicle to the auto store and have it diagnosed and possibly repair or replace your axle.

3.Shuddering or vibrating car– A faulty rear axle may also cause shuddering or vibration felt throughout the vehicle. If these are accompanied along with the weird noises mentioned above, then it is a sign to call in the mechanic immediately.

4.Car doesn’t move– In case of an internal failure, power won’t be transferred to the drive wheels and the axle won’t spin the front or rear wheels. If this happen, the vehicle quite obviously won’t move at all and will need rear axle replacement before it will start functioning again.
