Rack Boots on the 2016 Subaru Impreza: What You Need to Know

The 2016 Subaru Impreza, like many modern vehicles, features a rack and pinion steering system designed to provide responsive and precise handling. One question that often comes up when servicing or inspecting the steering system is whether this particular model uses rack boots, and if so, what purpose they serve and how to maintain them.

To clear things up, rack boots are indeed fitted to the 2016 Subaru Impreza. They are an important component of the steering rack assembly. These flexible rubber or thermoplastic covers are located on either end of the steering rack, surrounding the inner tie rods. Their primary purpose is to protect the internal components of the steering rack from dirt, water, grease, and other contaminants that could accelerate wear or cause damage.

The steering rack in the 2016 Impreza is a tightly engineered assembly made up of the rack bar, pinion gear, inner tie rods, and seals. The rack boots serve as a barrier to keep debris out while also retaining lubrication inside the rack housing. Without them, the rack would be exposed to all sorts of contaminants that would quickly degrade the seals and bearings. This could lead to steering issues such as increased play, noise, or even failure of the rack unit.

Given the crucial role of the rack boots in protecting the steering system, regular inspection and maintenance as part of routine servicing is highly recommended. Over time, rack boots can suffer from wear, cracking, or tearing due to exposure to harsh road conditions, varying temperatures, and constant movement of the steering mechanism.

When maintaining the 2016 Subaru Impreza, mechanics will typically check the condition of the rack boots while the car is on a hoist or during wheel alignment procedures. Visible cracks, splits, or grease leakage on the outside of the boots indicate that they're compromised and should be replaced without delay. Failure to replace damaged boots can lead to grease loss and contamination that ultimately harms the steering rack, which can be a more costly repair.

Replacing rack boots on the 2016 Impreza usually involves removing the front wheels and disconnecting the inner tie rods from the steering rack. The old boots are carefully cut off, and the rack ends cleaned thoroughly to remove dirt and old grease. New boots are then slid into position and secured using clamps or bands that keep them firmly in place. Once refitted, fresh grease is applied inside the boots to lubricate the inner tie rods and rack assembly. This replacement process restores protection to the steering rack and helps maintain smooth and precise steering feel.

It is worth noting that when the rack boots are replaced, it may be a good opportunity to check the overall condition of the steering rack, tie rod ends, and ball joints. Sometimes a worn or loose component elsewhere in the steering system can accelerate rack boot wear, so addressing these areas as part of a comprehensive service can help extend the life of the rack boots and steering assembly.

Owners of the 2016 Subaru Impreza who regularly drive on rough or gravel roads, or frequently encounter wet and salty conditions, should pay special attention to the rack boots during servicing. Harsh environments increase the risk of damage through stone chips, abrasion, or water infiltration underneath the boots. Checking rack boots every 20,000 to 30,000 kilometres is generally a good guideline, or sooner if signs of grease leakage or boot damage appear.

In the end, taking care of rack boots on the 2016 Subaru Impreza is a smart move to protect the steering system, maintain safe handling, and avoid costly repairs down the track. While not the most glamorous part of the car, these humble rubber covers play a significant role in keeping your ride smooth and reliable.
