Control Arm (Left Hand Side Front Upper) – Toyota LandCruiser 100 Series
Replace your worn, bent, clunking or rusted left-hand (driver's side) front upper control arm on your Toyota LandCruiser 100 Series (HDJ100, HZJ105, UZJ100, 1998-2007) with this heavy-duty replacement from Machter Auto Parts. Direct fit for the front upper lateral control arm – fixes steering play, knocking over bumps, poor handling, tyre rub or uneven wear after high mileage, towing, off-road abuse, corrosion or lift kits on these IFS Cruisers in Australia.
Key Features
- Single left-hand (LH/driver's side) front upper control arm – complete ready-to-install unit
- Direct bolt-on fit for 1998-2007 Toyota LandCruiser 100 Series (all variants: petrol & diesel)
- High-strength steel construction – thicker than factory for added rigidity and load capacity
- Matte black powder coat finish – rust-resistant and low-glare for off-road use
- Pre-installed high-density polyurethane or rubber bushings – greaseable, long-lasting and reduced deflection
- Precision-welded end fittings – maintains correct length and geometry
- Compatible with factory or aftermarket ball joints, shocks, coils and suspension kits
Benefits
- Eliminates clunks & front-end play – tighter, more precise steering and quieter ride
- Restores correct suspension geometry – reduces tyre wear, improves stability and handling
- Stronger than worn factory arm – handles heavy towing, rock crawling or high-speed dirt roads
- Prevents further damage – stops stress on ball joints, tie rods, bushings and diff
- Essential for roadworthy & safety – bent or rusted arms can fail inspection in NSW
- Great for high-mileage work rigs, off-road builds or resto projects – brings front suspension back to solid
Fitment Notes
- Suitable for Toyota LandCruiser 100 Series (1998-2007) – front upper control arm (left hand/driver's side)
- Professional installation recommended – torque bushings/bolts to spec, re-align vehicle (caster/camber/toe) and test drive
- Replace both sides together – worn arms cause uneven handling and wear
- Inspect lower arms, panhard rod, shocks, ball joints & diff mounts while replacing – common to do full front suspension refresh
- May require alignment after install – especially if lifted or running larger tyres

Frequently Asked Questions
What are the symptoms of a failing front upper control arm?
The most obvious signs are a metallic knocking or clunking sound when driving over bumps or turning the wheel, steering wheel vibration, and uneven tyre wear (particularly on the inner or outer edges). You might also experience a "wandering" sensation at highway speeds, where the front end feels loose or unresponsive.
Does this control arm include the ball joint and bushings?
Yes, this is a fully assembled unit that comes pre-fitted with high-quality inner pivot rubber bushings and a pre-greased upper ball joint. Replacing the complete arm assembly is significantly faster and more economical than attempting to press old bushings and ball joints out of a fatigued factory arm.
Can I use this left-hand side control arm on the right-hand side?
No, they are not interchangeable. Because the Independent Front Suspension (IFS) geometry is mirrored, the Left-Hand Side (LHS - passenger side in Australia) control arm has a distinct shape, brake line bracket location, and ball joint angle compared to the Right-Hand Side (RHS) arm. You must install the correct side for safe vehicle tracking.
Will this upper control arm fit a solid-axle 105 Series LandCruiser?
No, this item will not fit. The 105 Series utilizes a live/solid front axle layout with leading radius arms, meaning it does not have upper or lower control arms. This part is exclusively designed for the Independent Front Suspension (IFS) setup found on 100 Series models, such as the UZJ100 (V8 petrol) and HDJ100 (turbo-diesel).
Do I need a wheel alignment after fitting this control arm?
Yes, a professional wheel alignment is absolutely mandatory after replacement. The front upper control arm dictates your wheel's camber and caster angles. Even minor deviations between the old worn component and the new assembly can severely impact steering stability and cause rapid tyre scrub if not properly aligned.
