Stop rear-end clunks, loose handling, axle wrap, vibration and vague rear feel on your Toyota LandCruiser 80 Series (FZJ80/HDJ80/HZJ80/HDJ81 1990-1997) or 105 Series (FZJ105/HZJ105 1998-2007) with these upper rear trailing arm bushes from Machter Auto Parts. Replaces the cracked, perished or collapsed factory rubber bushes in the upper trailing arms – restores tight axle location, reduces driveline slop and improves stability for work rigs, lifted trucks, tourers or daily drivers that feel noisy or sloppy on corrugations, gravel or highways in Australia.

- Greaseable design – serviceable with zerk fittings for easy maintenance
- Precision-machined – exact OEM shape and thickness for leak-free fit and alignment
- Compatible with factory or aftermarket trailing arms and suspension setups
Benefits
- Kills clunks & vibrations – quieter rear suspension over bumps & rough roads
- Reduces axle wrap & driveline play – better power transfer and less U-joint stress
- Improved handling & stability – less squirm when loaded, towing or cornering
- Longer life than factory rubber – polyurethane won't squash or degrade over time
- Essential for high-mileage or lifted 80/105 Series – fixes common bush failure symptoms

Fitment Notes
- Suitable for Toyota LandCruiser 80 Series (FZJ80/HDJ80/HZJ80/HDJ81 1990-1997) and 105 Series (FZJ105/HZJ105 1998-2007) rear upper trailing arms
- Professional installation recommended – press bushes in/out (use bushing press or tool), grease during assembly and torque arm bolts to spec

Frequently Asked Questions
What role do the upper trailing arm bushes play?
The upper trailing arms (or control arms) are critical for maintaining the pinion angle and preventing the axle housing from rotating during acceleration and braking. Worn upper bushes allow the axle to "wind up," which can cause significant driveline vibrations, clunking during gear changes, and a "slop" in the drivetrain feel.
How can I tell if my upper trailing arm bushes are failing?
A key symptom is a "clunk" when you transition from accelerating to coasting, or vice versa. If you jack up the rear of the vehicle safely, you can often physically wiggle the upper arms to check for play in the rubber bushings. If you feel any movement or see visible cracking/tearing of the rubber, they are due for replacement.
Do I need to replace all four upper bushes at the same time?
Yes, it is highly recommended. The upper trailing arm system relies on balanced tension across both arms. If one bush has failed, the others are likely near the end of their service life as well. Replacing the set ensures that the axle is held firmly and evenly, preventing uneven strain on your remaining healthy bushings.
Are these rubber or polyurethane bushings?
These are premium rubber replacements. Rubber is the preferred choice for most 80/105 Series owners because it excels at absorbing road noise and high-frequency vibrations, maintaining that plush, factory-standard ride quality that many aftermarket polyurethane bushings tend to compromise.
Is this installation different from the lower trailing arm bushes?
The process is similar in principle—requiring the removal of the arms and the use of a press—but the upper arms are often in a tighter space, making removal slightly more fiddly. Always ensure the axle is supported properly with stands before removing the arms, as the axle housing can rotate when the arms are unbolted.
