The Importance of a Detailed Inspection

Alright, now that you're getting acquainted with your FJ40, it's time for the first major step: a thorough inspection. This isn't just a quick once-over; we're talking about a meticulous, detail-oriented assessment of every single component. Begin by documenting everything. Take photos, videos, and make notes of the condition of each part. This documentation will be a lifesaver later on when you're ordering parts, tracking your progress, and comparing your work.

Start with the body. Look for rust, dents, and any signs of previous repairs. Rust is the FJ40's worst enemy, so pay close attention to the floorboards, wheel wells, rocker panels, and the frame. The cabrio top, being exposed to the elements, is especially prone to corrosion. Inspect the condition of the top, its mechanisms, and the surrounding body panels. Check the alignment of the doors, hood, and tailgate. Do they fit properly? Are there any gaps or misalignments that need addressing? Then, move on to the frame. The frame is the backbone of your FJ40, so its structural integrity is paramount. Inspect it for rust, cracks, and any signs of damage. Pay special attention to the areas around the suspension mounts, steering box, and engine mounts. Check for any previous welding or repairs and assess their quality. Next, inspect the engine. Does it turn over? Does it have good compression? Look for leaks, both oil and coolant. Check the condition of the belts, hoses, and wiring. A visual inspection can reveal a lot, so use your eyes and your hands! Examine the transmission and transfer case for leaks and unusual noises. Test the clutch (if applicable) and shifter. Investigate the suspension, including the shocks, springs, bushings, and steering components. Check for wear and tear, and make sure everything moves freely. Finally, examine the interior. Check the condition of the seats, dashboard, and gauges. Look for any signs of water damage or rodent infestation. Test all the electrical components, including the lights, wipers, and horn. Note down which parts need to be replaced, repaired, or restored. Be honest with yourself, and don't skip anything. The more detailed your inspection, the better prepared you'll be for the restoration journey.

Disassembly and Preparation

Alright, after your comprehensive inspection, it's time to get your hands dirty and begin the disassembly process. This part of the restoration can feel daunting, but it's also incredibly rewarding. The key is to be organized, patient, and methodical.

First things first: Safety first, always! Wear appropriate safety gear, including eye protection, gloves, and a mask. Make sure you have a well-ventilated workspace. Begin by disconnecting the battery and draining all fluids (oil, coolant, fuel, etc.). Label everything! As you remove parts, label them clearly with their location and purpose. Use masking tape and a permanent marker. Take photos and videos throughout the disassembly process. These will serve as a visual reference when it comes time to reassemble your FJ40. If possible, organize the parts by system (engine, transmission, body, etc.). This will make it easier to manage and keep track of everything. Consider using plastic bins or labeled boxes to store parts. Start with the body panels. Carefully remove the doors, hood, fenders, and cabrio top. Take note of any shims or adjustments needed for proper fitment. Next, remove the interior components, including the seats, dashboard, carpets, and trim. Be extremely cautious when removing fragile parts, such as the gauges and wiring. Now, move on to the engine, transmission, and transfer case. Disconnect all the wiring, hoses, and linkages. Carefully remove the engine and transmission from the frame. If you're not comfortable with this step, consider having a professional mechanic assist you. Once you have the frame stripped, clean and inspect it thoroughly. Check for rust, cracks, and any other damage. Depending on the condition, you may need to repair or replace the frame. Now, remove the suspension components, including the springs, shocks, axles, and steering components. Disassemble these components and inspect them for wear and tear. You'll likely need to replace bushings, seals, and other worn-out parts. At this stage, it's also a good time to strip the body panels of paint. This can be done by media blasting, chemical stripping, or sanding. Make sure to take all safety precautions when removing paint, especially if it contains lead. This is where your detailed documentation from the inspection phase comes into play. Now is when you will start ordering your replacement parts.

Bodywork and Rust Repair

Ah, the dreaded rust! It's the nemesis of all classic car owners, and the FJ40 is no exception. However, fear not, because with the right tools, knowledge, and patience, you can tackle even the most severe rust issues. This is where your metalworking skills will be put to the test.

First, assess the extent of the rust damage. Determine which panels need to be replaced, which can be repaired, and which are salvageable. It's often more cost-effective to replace heavily rusted panels, but smaller areas can be repaired. Before you start cutting or welding, make sure you have the necessary safety equipment, including a welding helmet, gloves, and a fire extinguisher. Start by removing the rust. You can use various methods, including media blasting, wire brushing, or grinding. Make sure to remove all the rust down to bare metal. If you're removing rust from the frame, consider taking it to a professional media blaster to ensure complete removal. Next, cut out the rusted sections. Use a cutting wheel or a plasma cutter to remove the damaged metal. When cutting, make sure to leave enough overlap for welding. Fabricate or purchase replacement panels. You can often find replacement panels for the FJ40 from various aftermarket suppliers. If you need to fabricate your own, use sheet metal of the appropriate gauge. When welding, make sure to use the correct welding technique and settings. Practice your welding skills on scrap metal before tackling the FJ40. After welding, grind down the welds and smooth the surface. Use body filler to smooth out any imperfections. Once the bodywork is complete, it's time to move on to the paintwork. This is a crucial step that will determine the final appearance of your FJ40. Start by preparing the surface. This involves sanding, priming, and applying a sealer coat. Choose a high-quality primer and sealer coat. Apply several coats of paint, allowing each coat to dry properly before applying the next one. Use a high-quality paint, such as enamel or polyurethane. Consider hiring a professional painter. Painting a car is a skill that takes years to master, and a professional painter can often achieve a better finish. Don't forget about the cabrio top. Inspect the top for any damage, such as tears or cracks. If the top is damaged, you may need to repair or replace it. Clean and restore the top's mechanism. This may involve replacing worn-out parts and lubricating the moving components.

Engine and Mechanical Restoration

Now, let's turn our attention to the heart of your FJ40: the engine. Whether you're planning a complete engine rebuild or a more straightforward tune-up, this is an important part of the restoration.

If you're planning a complete rebuild, remove the engine from the frame. Disassemble the engine completely. Take detailed notes and photos as you disassemble the engine. Send the engine block, cylinder head, crankshaft, and connecting rods to a machine shop. Have the machine shop inspect the components and perform any necessary machining work, such as boring, honing, and resurfacing. Replace all worn-out parts, including the pistons, rings, bearings, gaskets, and seals. Assemble the engine according to the manufacturer's specifications. Make sure to use the correct torque specifications. After the engine rebuild, move on to the mechanicals. Inspect the transmission and transfer case. Replace any worn-out parts, such as gears, bearings, and seals. Rebuild the axles. This may involve replacing bearings, seals, and gears. Inspect the brakes, including the master cylinder, brake lines, and calipers. Replace any worn-out parts. Check the steering components, including the steering box, tie rods, and idler arm. Replace any worn-out parts. Also, install the suspension components, including the springs, shocks, and bushings. Make sure that you have the right components for the year of your FJ40. You can also upgrade to improve ride quality. Lastly, prepare the interior, including the seats, dashboard, and carpets. You will want to replace any worn-out parts or repair any damage. Now is also a good time to go ahead and begin with the wiring. Ensure all wires are correctly connected and that you have all the original wiring components.
