If you’ve driven a Nissan Primastar, Renault Trafic, or Vauxhall Vivaro X83 for any length of time, you’ll know they’re solid, dependable vans… but they do start to feel tired at the rear axle once the original rubber bushes wear out. (we also make the front Subframe Bushes – Here)
It’s one of those jobs that creeps up gradually. A bit of rear-end movement here, a vague feeling on the motorway there, maybe even a knock over sharp bumps. Most owners don’t immediately suspect the rear axle bushes – but they’re often the culprit.
That’s exactly what the Polybush 47H rear axle bush kit is designed to address.
The rear axle bushes sit between the axle beam and the vehicle chassis. Their job is simple in theory: control movement while isolating vibration.
Over time, the factory rubber bushes degrade due to:
Once that happens, the axle can shift more than it should. That leads to:
On a fully loaded commercial van or camper conversion, the symptoms can feel even more pronounced.
The Polybush 47H bush set replaces the original rubber bushes with a precision-engineered polyurethane alternative designed specifically for this X83 platform.
Unlike standard rubber, polyurethane is far more resistant to deformation under load, which means the axle stays better controlled without introducing harshness.
Key benefits include:
It’s a proper “fit and forget” upgrade, which is exactly what most van owners are after.
This set (Part Number 47H) fits:
OEM cross references include:
91165701, 93856473, 4412907, 4417121, 8200431675, 8200039132, 55466-00QAA
In the accompanying fitting video, we walk through the installation of the Polybush 47H rear axle bushes on the X83 platform.
The focus is on:
Even if you’re not doing the job yourself, the video is useful for understanding what’s involved and what a proper installation should look like.
This isn’t a “performance mod” – it’s a practical upgrade for real-world vehicles.
It’s especially relevant for:
If your van feels like it’s not quite as tight as it used to be, this is one of the first areas worth inspecting.
Rear axle bushes are often overlooked, but they play a massive role in how stable and controlled a van feels on the road.
The Polybush 47H offers a long-term solution that restores control without sacrificing comfort – making it a smart upgrade for anyone running the X83 platform seriously, whether for work or travel.
If you want to improve handling, reduce rear-end movement, and avoid replacing worn rubber again in a few years, this is one of the most effective upgrades you can make.
