Upper Ball Joint For Front Upper Adjustable Control Arm – Control Arm Kit
Upgrade or replace the upper ball joint in your front adjustable control arm on your lifted or modified Toyota LandCruiser (80 Series, 105 Series, 70 Series solid axle, or compatible models) with this heavy-duty upper ball joint from Machter Auto Parts. Designed for high-angle adjustable upper control arms (aftermarket long-travel or lift kits), it provides stronger articulation, tighter steering feel and longer life – essential for off-road builds, rock crawling, towing or running larger tyres where factory ball joints bind, wear out fast or fail under extreme angles and loads in Australia.
Key Features
- Heavy-duty upper ball joint – greaseable with zerk fitting for easy service
- Direct fit for most aftermarket adjustable front upper control arms on Toyota LandCruiser 80/105/70 Series (solid axle or IFS)
- High-strength forged steel stud & housing – handles high-angle articulation and heavy loads
- Precision-machined taper & threads – secure fit in control arm with no play
- Reinforced boot – keeps grease in and contaminants out for long life in mud/dust/water
- High-temp grease pre-packed – smooth operation and reduced wear
- Compatible with factory or aftermarket upper control arms, knuckles and tie rods
Benefits
- High-angle capability – allows full suspension travel on lifted or long-travel setups without binding
- Eliminates steering play & clunks – tighter, more precise steering feel
- Longer life than stock ball joints – greaseable design handles off-road abuse & heavy towing
- Prevents premature wear – stronger construction reduces stress on knuckles & tie rods
- Essential for lifted 80/105/70 Series – fixes common ball joint failure on adjustable arms
- Great for off-road builds, work rigs or resto projects – keeps steering solid & safe
Fitment Notes
- Suitable for aftermarket adjustable front upper control arms on Toyota LandCruiser 80 Series (1990-1997), 105 Series (1998-2007) and 70 Series solid axle models
- Professional installation recommended – torque ball joint nut to spec (usually 100-150 Nm), grease joint and re-align steering
- Replace both sides together – worn ball joints cause uneven handling and wear
- Inspect lower arms, panhard rod, knuckles & tie rods while replacing – common to do full front suspension refresh
- Confirm your control arm type – designed for adjustable upper arms (not factory fixed arms)

Frequently Asked Questions
What are the symptoms of a worn front upper ball joint?
Common symptoms of a failing upper ball joint include a metallic clunking, popping, or knocking noise from the front suspension when traveling over bumps or turning. You may also notice steering wheel vibration, a drifting or wandering sensation to one side, and severe, uneven tyre wear on the inner or outer edges.
Is this ball joint compatible with factory-standard control arms?
No, this replacement upper ball joint is specifically designed to fit heavy-duty aftermarket adjustable upper control arms (UCAs). It features a threaded or specialized housing configuration meant for adjustable geometry arms used on lifted vehicles, and will not bolt or press into a standard factory-style stamped control arm.
Why do lifted vehicles require heavy-duty adjustable upper control arm ball joints?
When you lift an Independent Front Suspension (IFS) vehicle, the operating angle of the upper control arm drops drastically, pushing factory ball joints to their maximum physical limit. This causes binding and premature boot failure. Heavy-duty adjustable control arm ball joints are engineered with a greater range of motion and a revised angle to restore suspension travel and wheel alignment clearance.
Does this ball joint fit both the left and right sides of the vehicle?
Yes, this individual upper ball joint features a symmetrical non-directional design. This means it is fully interchangeable and can be installed into either the Front Left-Hand Side (LHS) or Front Right-Hand Side (RHS) aftermarket adjustable control arm housing.
Do I need an alignment after replacing an upper control arm ball joint?
Yes, a professional wheel alignment is absolutely essential following installation. Because this ball joint attaches to an adjustable control arm assembly that directly determines your vehicle's camber and caster angles, resetting or altering this pivot point will change your alignment metrics and can cause severe tyre scrubbing if left uncorrected.
