Shocks
EFS Shock Absorber Bush, bonded rubber-to-steel, lower — for shock 38-5648
A worn shock bush puts a knock into every bump and lets the suspension move where it should not, even when the damper itself is still healthy. This EFS bonded rubber-to-steel bush measures 42/30 x 41 x 14 mm and fits the lower mount of shock 38-5648. The rubber is bonded to the steel sleeve, so the joint does not develop play after a couple of seasons.
EFS Shock Absorber Bush, bonded rubber-to-steel, lower — for shock 38-5648
A metallic knock over a kerb rarely means the damper is finished. Far more often the part that has given up is the thing connecting it to the vehicle: the rubber bush in the lower eye. Once the rubber cracks or separates from the steel, the shock works with play and vibration goes straight into the body.
This EFS bush is the replacement wear part for the lower mount of shock 38-5648. A steel sleeve is surrounded by hard-wearing rubber bonded to the metal rather than simply pressed against it, and that difference is what keeps the joint tight after thousands of rough kilometres.

Key benefits
- Rubber bonded to steel, so there is no play and the joint holds up in hard conditions.
- Damps vibration and cuts noise, which means fewer knocks reaching the cabin.
- Resistant to abrasion, oils and weather — this part lives under the vehicle, where salt, mud and grease are a given.
- Maintenance free: no greasing and no periodic retightening.
- Replacing a bush costs a fraction of a complete shock when the damper itself is still good.

Who it is for
For owners of vehicles running EFS shock 38-5648: Nissan Pathfinder R51 from 2005, Navara D40 from 2005 to 2015, Navara D23/NP300 on leaf springs from 2015, Mercedes X-Class 4Cyl from 2017 to May 2020 and Renault Alaskan from 2017 in the Thai-built version. If a knock has appeared at the lower mount after a season of hard use, the bush is where to start.
Fitting notes
The old bush is pressed out of the shock eye and the new one pressed in, which is easiest with a press. Check how many bushes your mount takes, and always replace them in pairs across an axle so the suspension works symmetrically.
Why buy it
- Defined dimensions and a defined application — no measuring and guessing.
- You fix the cause of the knock for a fraction of the cost of a new damper.
- Maintenance free construction built for life under the vehicle.
If your EFS shock carries part number 38-5648, this is the bush you are looking for.
