We'll follow my channel's format for common problems broken into sections.

First we'll cover some common issues with the engine. The 4Runner in this generation had 2 possible engine options in most markets. The 4.0L 1GR-FE V6 and the 4.7L 2UZ-FE V8 engine. Although those engines are solid options they do have some issues that are common.

Then the Transmission of the 4Runner. 2 Possible options, The 4 speed and the 5 speed. Both are very solid transmissions with very few minor issues. Make sure you replace your 4th generation 4Runner transmission fluid every 60,000 miles or 6 years so you won't have to worry about the transmission filter.

I'll also cover common issues with the 4WD system. Make sure you use your 4WD frequently as instructed by the owner's manual. This alone will prevent many of the issues.

I'll also cover items on Chassis, Body and Electrical. Including issues with suspension and a common knocking noise that is very simple and inexpensive to fix. Brakes are generally good on this truck however rust does affect them which is a theme with this truck.

Lastly we'll have the frame rust conversation. This is possibly the biggest problem with this truck. One that can basically mechanically total this truck. Be very careful when shopping for one. Do NOT buy a 4runner that's rusty. And always under coat the frame to protect it from rust.
