Front Engine Mounts – Toyota LandCruiser 70 Series (HZJ70 HZJ73 HZJ75 HZJ78R HZJ79R)
Eliminate engine clunks, excessive vibration, and harsh driveline feel on your Toyota LandCruiser 70 Series (HZJ70, HZJ73, HZJ75, HZJ78R, HZJ79R) with this set of front engine mounts. Designed specifically for these 1HZ/1HD-T diesel models, these heavy-duty replacements restore smooth power delivery, reduce cabin shake, and protect the gearbox and tailshaft from excessive movement – ideal for work utes, troop carriers, single/double cabs, or high-mileage rigs that have done years of towing, off-road work, or daily duties in Aussie conditions.
Key Features
- Sold as a pair (left + right front engine mounts) – complete set for the engine side
- Direct bolt-on fit for 70 Series models: HZJ70 / HZJ73 / HZJ75 / HZJ78R / HZJ79R (1990s–current, 4.2L 1HZ/1HD-T diesel)
- Heavy-duty rubber compound bonded to reinforced steel brackets – resists heat, oil, ozone, and cracking
- Upgraded design with higher load capacity – handles torque from towing or hard acceleration better than worn OEM
- Precision-moulded for exact OEM alignment – no shims or mods needed
- Compatible with factory or aftermarket transmission crossmembers and rear engine mounts
Benefits
- Stops clunks and vibrations – smoother gear shifts, quieter cabin, and less fatigue on long drives
- Reduces stress on driveline – protects gearbox mounts, tailshaft U-joints, and diff from premature wear
- Improves engine alignment & power transfer – better throttle response and stability under load
- Restores factory ride quality – especially noticeable after replacing all mounts (front + rear + trans)
- Essential for roadworthy & safety – collapsed or cracked mounts can fail inspection in NSW
- Perfect for work trucks, off-road builds, or resto projects – keeps your 70 Series solid and reliable
Fitment Notes
- Specially designed for 70 Series HZJ70 / HZJ73 / HZJ75 / HZJ78R / HZJ79R (1HZ/1HD-T diesel engines)
- Professional installation recommended – support engine/transmission during swap, torque bolts to spec (consult service manual)
- Replace all engine/transmission mounts at once for balanced damping and best results
- Inspect bellhousing bolts, crossmember, tailshaft, and exhaust hangers while mounts are off

Frequently Asked Questions
What are the symptoms of worn or collapsed front engine mounts on a 1HZ?
The most prominent warning sign is an excessive, uncomfortable vibration felt throughout the cabin floorboards and gear sticks, particularly when the engine is idling. You might also experience a distinct mechanical clunk or thud from the engine bay when taking off from a standstill or backing off the accelerator quickly, which happens when the engine block lifts and drops due to torn rubber insulators.
Which specific LandCruiser models and engine series does this mount pair suit?
This heavy-duty front engine mount set is specifically engineered to support Toyota’s iconic 4.2-litre 6-cylinder naturally aspirated 1HZ diesel engine. It is a direct replacement for the 70 Series workhorse family, including the leaf-sprung HZJ75 and the coil-sprung HZJ78 Troop Carrier and HZJ79 Cab-Chassis models.
Is this product supplied as a complete set for the front of the engine?
Yes, this listing is bundled as a 2-piece package containing both matching front engine insulators. Swapping both the Left-Hand Side and Right-Hand Side mounts at the same time is highly recommended because they share identical load stresses; replacing only one side places uneven twisting forces on the fresh rubber, causing it to fail prematurely.
Why do engine mounts fail on touring and off-road 4WD rigs?
The 1HZ is a heavy piece of cast iron that generates significant rotational torque. Continuous outback driving across rough corrugations, coupled with low-range engine braking on steep tracks, puts immense physical tension on the rubber blocks. Over time, engine oil leaks, road grime, and constant heat cycles degrade the vulcanized rubber bond, causing it to split, perish, or completely separate from the steel mounting plates.
What is the safest method for installing these replacement mounts?
Proper execution is critical to avoid cross-threading bolts or damaging the oil pan. Ensure the vehicle is parked safely on level ground. You must support the weight of the engine using a hydraulic trolley jack and a wide block of wood positioned under the structural lip of the oil sump. Carefully lift the engine just enough to relieve load tension, unbolt the old brackets, slide the new high-compliance insulators into position, thread all fasteners by hand first, and then torque them to factory metric specifications.
