1st Gen Tacoma Rust Prevention for Older Trucks

Rust Prevention: Keeping Your 1st Gen Alive

First generation Tacomas are between 22 and 31 years old. Rust is the number one killer of these trucks, especially in salt-belt states. With the right approach, you can keep your 1st gen on the road for decades more.

Annual Rust Prevention Routine

1. Pressure wash the entire undercarriage in late fall before salt season
2. Apply Fluid Film or Woolwax to the frame, crossmembers, leaf springs, and body seams
3. Inspect bed mounting bolts, cab mounting bolts, and frame-to-body hardware
4. Check inner fenders, rocker panels, and the lower doors for bubbling paint
5. Treat any surface rust immediately — wire brush, rust converter, primer, and paint

Frame Inspection Points

• Rear frame sections near the spare tire carrier
• Front crossmember behind the front bumper
• Leaf spring mounting brackets and shackles
• Cab-to-frame mounting points

If you're in a rust-prone area and buying a used 1st gen, a thorough underbody inspection with a pick hammer is essential before purchase.
