Modified Pajero: 4×4 Vehicle Inspection Guide

4x4 vehicle inspection of a modified Pajero in Acacia Ridge by BPC Auto Inspect.

Thinking of picking up a modified Pajero from a specialist commercial dealer in Acacia Ridge? While a lifted Pajero looks ready for the Gibb River Road, heavy aftermarket modifications require an expert eye. Arranging a professional 4×4 vehicle inspection in Brisbane ensures you aren’t inheriting someone else’s dangerous mechanical nightmares or illegal structural modifications.

I recently performed a thorough Brisbane Southside mobile pre-purchase inspection on this Pajero along Beaudesert Road, followed by a detailed road test near Souths Sports Club. From verifying essential LM1 Mod Plates to assessing the health of the Pedders Air Assist suspension, here is what I look for during a comprehensive onsite used car inspection to ensure a modified 4WD is actually safe, reliable, and QLD transport compliant.

Pajero Suspension Upgrade: What to Look For Onsite

Pedders Air Assist Diagnostics

Adjustable air suspension has many benefits, such as improving load-carrying performance when towing. Who doesn’t want a little more height and stability after loading up to go travelling? Also, adding additional weight with upgrades like a long-range tank and dual-wheel carrier makes this Pajero suspension upgrade for towing essential.

Nolathane & Polyurethane Bush Component Wear

If the Pajero you own or choose to buy is for its intended purpose, you will see some premature wear. The good news is you should be able to find many workshops willing to give you a quote and also plenty of after-market replacement bushes like Nolathane or SuperPro.

While this Pajero is fitted with a heavy-duty lift kit, keep in mind that even the best setups rely on healthy rubber components.

While premium suspension modifications are excellent additions, they can occasionally mask underlying factory issues. Before committing to a purchase at an Acacia Ridge commercial dealership, make sure you are fully aware of the general common Mitsubishi Pajero issues that affect these models, including timing chain guide fatigue, intake carbon buildup, and DPF clogging.

Modified Pajero With Long Range Fuel Tank Compliance & Safety

Upgrading to a high-capacity long-range fuel tank significantly extends your driving range, making it one of the most practical additions for remote outback touring. However, ensuring it has been legally signed off is an indispensable step during local used car inspections. With the addition of a long-range auxiliary fuel setup, a certified LM1 modification plate is strictly required in QLD to keep the vehicle completely roadworthy and legally insured.

Auxiliary Tank Pros and Cons

Installing a long-range fuel tank offers several advantages. Primarily, it increases your vehicle’s range, allowing you to explore remote areas without running out of fuel. This added capacity can also be beneficial for those who frequently tow or carry heavy loads, which can increase fuel consumption. Additionally, it can save you time and money by reducing the number of refuelling stops.

However, there are some drawbacks to consider. A long-range tank can increase the overall weight of your vehicle, affecting its handling and fuel efficiency, especially in urban environments. Installation costs can also be high, and it’s essential to ensure the tank is properly fitted to avoid potential safety hazards.

Verifying the QLD LM1 Modification Plate

In Queensland, a long-range tank requires an LM1 plate. If you buy a Pajero in Brisbane without this plate, it’s technically unroadworthy, and your insurance may be void. I always check for the blue mod plate during my on-site inspections.

The LM1 modification plate is for fuel tank installation. A common modification and upgrade to any 4×4 is a long-range fuel tank. Here is a list of other vehicle modification codes.

Aftermarket Pricing & Popular Manufacturers

The cost of a long-range fuel tank varies depending on the vehicle’s make and model, tank capacity, and material. Generally, aftermarket tanks made from aluminium or steel are more expensive than plastic options. It’s essential to compare prices from different manufacturers and retailers to find the best deal. Keep in mind that installation costs can add to the overall expense.

Several reputable aftermarket manufacturers specialise in long-range fuel tanks. Some popular brands include the ARB long-range fuel tank, Brown Davis, and Long Ranger fuel tank. These companies offer a wide range of tanks to suit different vehicle models and budgets.

Consider reputable automotive aftermarket accessory stores or online retailers when purchasing a long-range fuel tank. Popular online platforms like eBay offer a variety of aftermarket tanks, but verify the product’s quality and authenticity before buying.

Note: Always consult with a qualified mechanic or installer to ensure the correct tank and installation process for your vehicle. Adhering to local regulations and safety standards is paramount.

By carefully considering the pros and cons, comparing prices, and choosing a reputable manufacturer or retailer, you can select the right long-range fuel tank to enhance your vehicle’s capabilities for your specific needs.

Swing-Away Rear Wheel Carrier Assessment

Twin rear wheel carriers can provide you with the ultimate rear-end protection, improve off-road abilities and give you the security of always having a spare tyre.

The swing-away rear wheel carrier, as you can see, is a smart idea. Quick and easy access to the rear, especially if you have a rear drawer storage system set up. They offer off-road stability, come equipped with durable steel construction, and make an excellent aftermarket off-road addition.
