1982-1991 Montero (generation 1) OEM Idler Arm Assembly

Kit contains:

Two machined brass bushings and a shim pack. You will need to provide the OEM idler, this rebuilds it with superior components, wheel bearing grease of your choosing is required for the rebuild, a factory service manual is suggested. Images showing complete units are merely to depict the final installation.

The Basic Info:

The idler arm works to support the pitman arm in the steering system. While your steering box and pitman arm do all of the actual hydraulic to mechanical work; moving the front wheels from left to right, the tie rod ends and drag link carry the force applied from the steering box. The idler arm’s job is to be a passive participant in the steering system, it’s there to support the pitman arm’s movements. The more support it provides, the firmer and more precise the steering is. The bushings the Kingpin shaft ride on are plastic from the factory. Other brands of 4×4’s use a similar style of steering and already have upgraded bushings and idler arms available to them, now the montero does too.

The problem(s):

- The idler arm is mounted outboard of the frame in front of the axle center line, this means that road dirt, salt, water and debris will come into contact with it every day.  The factory bushings for the idler arms are made of plastic and break down over time.

-Worn idler arm bushings result in steering slop and wander, premature tire wear, outer or inner cupping on the tires and most importantly, an unsafe vehicle to operate at 75 MPH.  A worn system will cause the vehicle to follow the cracks in the road, making things unpredictable and requiring extra effort on behalf of the driver.

The solution:

These brass bushings are superior in strength to the factory units in terms of durability and tensile strength, the stock bushings wear out and give your rig that ‘big truck’ loose steering feeling. The new bushings are made of brass alloy and they’re made to last. So get yourself some bushings, firm that steering back up and remind yourself of the handling that helped Mitsubishi rock the Dakar in these trucks.


This kit rebuilds the idler housing - You must have a Mitsubishi factory housing - At current time no aftermarket idler arm housings are confirmed to work. You'll be re-using your housing, clips, washers and arm with ball joint (can be replaced with a 555 or moog arm. However, purchase at your own risk, we're not responsible for their product variations, if any exist)
