If you drive a Ford Fiesta Mk7 (CB1, CCN 2008–2017), Fiesta Mk7 ST (2013–2017), Ford B-Max (2012–2017), Ford EcoSport CBW (2014-on), or Mazda 2 DE/DH (2007–2015), you may have noticed rear-end instability, uneven tyre wear, or excessive axle movement.
Our 40BR Rear Beam Bush is engineered to replace OEM part numbers: 1535296, 1751679, 1805815, 1805866, 1871475, 8V51-5K653-AA, AY11-5K653-AA, D65128460, Delphi TD1629W, and Febi 34748. It’s designed for everyday driving while providing long-lasting stability.
Original rubber bushes degrade with heat, moisture, road salt, and ozone exposure. Over time, they soften, crack, and detach from the sleeve, causing unwanted rear movement.
OEM bushes are soft to maximise comfort, but this leads to rear axle steer, unstable cornering, and increased tyre wear — especially noticeable in European driving conditions like winding Alpine roads or urban cobblestones.
Many OEM bushes are voided to allow flex. Once the rubber fatigues, these voids concentrate stress and accelerate failure.
The rear beam must:
Support lateral forces
Control braking loads
Maintain rear toe alignment
Isolate vibrations
Rubber loses integrity under prolonged load, resulting in geometry shifts and unpredictable handling — something no European driver wants on highways, mountain passes, or city streets.
Polyurethane resists oil, salt, ozone, and heat. It maintains performance for years, unlike rubber.
The 40BR bush is engineered to allow exactly the right movement — stabilising the rear axle without making the ride harsh.
From German Autobahns to French country roads, Italian autostrade to Spanish urban streets, the 40BR bush delivers predictable, safe handling without sacrificing comfort.
Reduced rear-end “thud” over bumps
Improved straight-line stability
Sharper, more predictable cornering
Our polyurethane bush minimises vibrations and noise, keeping your daily commute comfortable while your rear axle remains perfectly aligned.
The 40BR bush is a direct replacement, fitting without modification. Suitable for professional mechanics and knowledgeable DIYers alike.
During suspension overhauls
Rear brake replacement
Technical inspections or MOT advisories
European drivers face the same rear beam bush issues as UK drivers, often worsened by winter road salt and rough surfaces. Polyurethane is perfectly suited to these conditions.
The 40BR bush stabilises your rear axle, reduces repeat repairs, and maintains geometry for safer, more predictable handling.
