Everything You Need to Know About the CV Joint on the 2007 Subaru Impreza

The 2007 Subaru Impreza is a popular car known for its reliable performance and the iconic all-wheel-drive system that Subaru is famous for. One key component that plays an important role in the smooth running of the vehicle's drivetrain is the CV joint, or constant velocity joint. For anyone interested in keeping their Impreza in top shape, understanding what a CV joint does and how to maintain or replace it is pretty handy knowledge.

First off, the 2007 Subaru Impreza definitely comes fitted with CV joints. This is especially true because the Impreza uses a front-engine, all-wheel-drive layout which requires efficient transmission of power to the front wheels even as they turn and move up and down over bumps. CV joints are specifically designed to handle this kind of complex motion.

So, what exactly does a CV joint do on the 2007 Subaru Impreza? The purpose of the CV joint is to transfer torque from the transmission to the drive wheels at a constant rotational speed, without any significant increase in friction or play. Traditional universal joints (U-joints) can transfer power when the wheels turn, but they do so less smoothly and can cause vibrations, especially at sharper angles. CV joints solve this problem by allowing for a flexible connection that can bend in multiple directions without changing wheel speed.

On the 2007 Impreza, there are typically two types of CV joints used - the inner and outer CV joints. The outer CV joints connect the drive shafts directly to the front wheel hubs and have to accommodate a lot of movement as the wheels steer and bounce on the road. The inner CV joints connect the drive shafts to the differential and mainly handle changes in length caused by suspension movement. Both joints work together to ensure smooth and reliable power delivery to the front wheels, plus the rear wheels in AWD setups through the centre differential.

Now, looking at the maintenance side of things, the CV joint on the 2007 Subaru Impreza is designed to be relatively low maintenance but it is not completely worry-free. Each CV joint is protected by a rubber or plastic boot, known as the CV boot, which keeps grease in and dirt, water, and debris out. These boots are critical because if they get damaged or crack, the grease will leak out and contamination will creep in. This leads to premature wear or failure of the joint.

Owners of the 2007 Impreza should routinely inspect the CV boots during servicing or even occasionally while doing other maintenance tasks like an oil change or tyre rotation. Checking for cracks, tears or leaks around the CV boots is an easy way to catch potential problems early. If the boot is damaged, it's important to replace it as soon as possible and repack the joint with fresh grease if the joint itself is still in good shape.

Eventually, with enough wear or if neglected, the CV joint itself will start to show signs of failure. Common symptoms include clicking or popping noises when turning, vibrations during acceleration, or grease splattered inside the wheel arch. Ignoring these signs can lead to a completely failed CV joint which often means the vehicle won't move and can result in a costly repair.

When it comes to replacement, swapping out a worn or damaged CV joint on the 2007 Subaru Impreza is usually quite straightforward for a skilled mechanic. Most of the time, the entire drive shaft assembly is replaced rather than just the joint, mainly because it saves time and ensures reliability. Replacement parts are widely available due to the popularity of the Impreza, which helps keep repair costs reasonable.

Some handy pointers for owners include addressing any CV joint issues sooner rather than later. The longer a damaged joint or boot is left unattended, the more expensive the repair will get. During routine servicing, having the CV boots checked should be part of the standard inspection checklist, especially given Australian road conditions which can be rough and expose boots to wear and tear.

In terms of driving style, avoiding aggressive driving and rough off-road use can extend the life of CV joints. While the Impreza is well-suited to all sorts of Australian conditions, being gentle on acceleration and taking care when driving over potholes or rocky surfaces can reduce stress on the drivetrain components including the CV joints.

All in all, the CV joint is a vital part of the 2007 Subaru Impreza's drivetrain. It allows the car's all-wheel-drive system to function smoothly, coping with the tough job of transmitting power reliably to the wheels no matter the angle or suspension movement. Paying attention to CV boot condition and addressing any issues early will keep the CV joints healthy and ensure many trouble-free kilometres ahead. Whether it's a routine service inspection or a bit of DIY care, keeping the CV joints in good nick is a smart move for any Impreza owner aiming to keep their car running like a champ.
