Buying a Cat Eye Truck: What to Look For and How to Evaluate

Purchasing a used Cat Eye Truck can be an excellent investment, but like any used vehicle, careful inspection is paramount. Knowing what common issues to look for can save you significant headaches and expenses down the road.

Common Issues to Inspect:

• Rust: This is perhaps the most significant concern, especially in areas where road salt is used. Pay close attention to the rocker panels, cab corners, wheel wells, bed supports, and the frame itself. Surface rust on the frame is often manageable, but extensive rot is a red flag.
• Transmission (4L60E/4L80E): The 4L60E automatic transmission, common in 1/2-ton models, can be a weak point, particularly at higher mileages or if subjected to heavy towing without proper maintenance. Check for delayed shifts, slipping, hard shifts, or any unusual noises. The 4L80E (often found in 3/4-ton trucks or those with the 6.0L engine) is generally more robust.
• Fuel Pump: Failure of the in-tank fuel pump is a common issue, often leading to no-start conditions or intermittent stalling. Listen for the pump priming when the key is turned to the "on" position.
• Steering and Suspension Components: Worn ball joints, tie rod ends, and idler/pitman arms are common due to age and mileage. Listen for clunks or pops when turning or going over bumps.
• Engine Leaks: Check for oil leaks from the valve covers, oil pan, or rear main seal. Exhaust manifold bolts breaking or leaking gaskets are also common, leading to ticking noises, especially on startup.
• Brakes: Ensure the brakes feel firm and responsive, with no pulsing or grinding.
• Electrical Issues: Test all power windows, locks, lights, and dashboard gauges.
• Interior Wear: Examine the dashboard for cracks, and check the seats for rips or excessive wear, especially on the driver’s side.

Inspection Checklist and Tips:

1. Bring a Friend: A second set of eyes can catch things you might miss.
2. Cold Start: Always try to see the truck started from cold to identify engine noises (e.g., piston slap, exhaust leaks) that might disappear once warm.
3. Test Drive: Drive the truck at various speeds, including highway speeds. Pay attention to steering feel, brake performance, transmission shifts, and any unusual vibrations or noises. Engage 4WD (if equipped) to ensure it works properly.
4. Service Records: Ask for any available maintenance history. A well-documented history is a good sign.
5. Pre-Purchase Inspection (PPI): If you’re serious about a truck, consider having an independent mechanic perform a PPI. This professional assessment can uncover hidden issues and provide peace of mind.
