Advice Blog

If you own a Mazda 2 (DE, DH) (2007-2015), Ford B-Max (JK) (2012-On), Ecosport (CBW) (2014-On), or a Fiesta Mk7 (CB1, CCN) – be it Non ST (2008-2017) or ST (2013-2017), you’ll know the frustration when your rear beam or rear axle bushes start to fail.

The OEM part numbers 1535296, 1751679, 1805815, 1805866, 1871475, 8V51-5K653-AA, AY11-5K653-AA are notorious for not living up to expectations, leaving many drivers dealing with constant repairs and a noticeably compromised ride.

The Dreaded Symptoms of Failing Rear Axle Bushes

Imagine driving your Fiesta, only to notice an unsettling looseness during the cornering. When the original rubber bushes fail, you typically experience symptoms such as excessive vibration, imprecise handling, and a general loss of feedback. The harsh reality is that your rubber bushes undergo stress daily – the plastic shell develops cracks, the rubber debonds from the tube, and the housing deteriorates. More than a mere inconvenience, a failing bush can lead to additional wear on other components, meaning more money is spent on repairs in the long run.

Why Polybush 40BR is the Best Choice

Now, imagine the transformation with the installation of the Polybush 40BR. Manufactured from premium polyurethane, this bush is engineered to withstand deflection and resist the natural wear and tear that plagues standard rubber. Here’s what you can expect:

  • Enhanced Driving Precision: With the voids removed from the original bush design, the 40BR offers a firmer connection between your chassis and axle. This means more precise handling through corners, improved grip, and overall better control of your Fiesta.

  • Retained Comfort: Despite its stiffer build, the design ensures that you still experience the original ride comfort of your car. Whether you’re just popping to the shops or pushing your Fiesta on the track, the upgrade benefits all driving styles.

  • Improved Tyre Life and Braking: By reducing unwanted deflection, your tyres experience less wear, and your braking system performs more reliably, making every journey feel secure and enjoyable.

A Hassle-Free Installation

Mechanics – and even those of us who aren’t professional mechanics – appreciate the ease of installing the Polybush 40BR. One of its standout benefits is that there is no need to remove the axle from your Fiesta. A straightforward, hassle-free installation means you’re back on the road in no time, enjoying the improved handling and ride quality that your car deserves.

Simple, hassle-free installation that gets you back on the road quickly.

A Final Word

For those who value comfort, reliability, and longevity, switching to polyurethane is a no-brainer. With failing rear axle bushes causing all sorts of headaches on models like the Mazda 2, Ford B-Max, Ecosport, and Fiesta Mk7, why settle for a temporary fix with rubber? Instead, opt for a solution that lasts. As we like to say, “Fit it once, fit Polybush.”

So, if you’re ready to put an end to the recurring failures and the mounting repair bills, give the 40BR a try. It’s a godsend for both garages and vehicle owners alike—a true upgrade for your ride that combines expert engineering with the simplicity of a perfect fit.
