1998 Toyota 4runner — Known Issues & Recalls

Your 4Runner's frame has developed rust that is causing the trailing arms (suspension parts that support your wheels) to detach while driving normally. This is a serious structural problem that could affect your vehicle's handling and safety.

The welded bracket that connects your rear control arm to the frame on the driver's side has rusted through and broken off completely. This happened while you were accelerating from a stop, causing a loud pop and making the rear end of your vehicle feel unstable and difficult to control. You'll likely need frame repair or replacement of the mounting bracket, which may require welding.

Your 4Runner's frame has rusted completely through in at least one spot, creating a hole. This structural damage prevents you from selling, registering, or using the vehicle, even though the engine and mechanical systems still run well. Repairing a rusted-through frame typically requires professional welding or frame replacement, which is a major repair on older vehicles.

Your vehicle's frame is rusting severely and has become unsafe, despite having only 68,000 miles. Specifically, the rear trailing arm bracket has developed a hole through it due to rust damage. Addressing this will likely require professional frame repair or replacement of the affected structural components.

Your 4Runner's frame has rusted so severely that you cannot pass vehicle inspection. This is a structural integrity issue that prevents you from getting your vehicle legally inspected. Frame rust repair typically involves removing the corroded sections and welding new metal in place, or in severe cases, replacing the entire frame.

Your vehicle failed a safety inspection due to severe rust on the frame. Frame rust can compromise your vehicle's structural integrity and safety. The frame will likely need professional inspection and repair or replacement of rusted sections.

Your 4Runner's rear suspension is sagging, and there is an active safety recall (NHTSA Campaign 02V021000) for 1998 4Runners that involves replacing rear suspension parts. Under heavy loading combined with sharp steering, this condition could cause loss of control and increase crash risk. You should contact Toyota at 1-800-331-4331 to schedule the free recall repair at an authorized dealer, even though your vehicle was imported from Japan to Canada.

Your 4Runner is swaying side to side while driving, and you've discovered that the rear axle support frame has rusted completely through the hollow structural tube. This structural rust is compromising the integrity of your vehicle's suspension support system. Addressing this will likely require welding repairs or replacement of the affected frame sections.

Severe rust on your frame caused the rear driver-side control arm mount to completely rust away and detach from the frame while your daughter was driving at low speed into a parking lot. This is a structural failure that compromises suspension integrity and vehicle control. The repair will require frame inspection, rust treatment, and replacement or reinforcement of the control arm mount.

Your 4Runner feels unstable while driving and makes noises from the body. When inspected, the frame has rusted completely through in multiple spots. This frame rust will need to be professionally assessed and repaired to restore vehicle stability and safety.

Your 4Runner's frame is severely rusted and has begun breaking apart while driving. You experienced violent rear-end swinging, which you managed to control before crashing. The frame deterioration poses a serious risk since it can fail suddenly and cause loss of vehicle control at any time.

While accelerating on a city street, your vehicle's rear end started to fishtail (slide sideways). A Toyota dealership discovered that the frame had rusted through and broken at the point where the rear control arm connects to the driver's side rear axle. This structural failure caused the loss of rear suspension control, creating a dangerous handling issue despite the vehicle being well-maintained with no accident history.

Your steering system failed when the driver's side front lower ball joint completely broke off while driving at about 15 mph, causing the wheel and tire to separate from the vehicle. This loss of a wheel creates an immediate loss of control and stability. The ball joint will need to be replaced, and the wheel assembly should be inspected for damage.

Your 4Runner was involved in a front-driver-side crash at 30 mph. The front driver-side airbag deployed, but the side airbag did not deploy during the collision. The vehicle was declared a total loss and was not inspected by Toyota to determine why the side airbag failed to activate. Diagnosis would require inspection of the airbag control module and side airbag wiring harness to identify the failure point.

Your 4Runner's rear sway bar attachment on the passenger side has rusted through and broken away from the frame, and the sway bar link on the other side has also snapped. The frame near these areas is rotting away, which caused noticeable swaying while driving. Additionally, your driver's side seat belt occasionally unlatches while you're driving. This will require replacing the rusted sway bar components, repairing the frame, and servicing the seat belt mechanism.

While driving, your truck suddenly swayed wildly and swerved into the opposing lane. After pulling over to investigate, you discovered the frame is severely rusted and rotted away. This structural damage is a serious safety issue that affects your vehicle's stability and handling, and you're concerned about liability and repair costs given reports of frame rust problems in Toyota trucks.

Your 1998 Toyota 4Runner's frame has severe rust damage that makes the vehicle unsafe to drive. The body is rocking on the frame, indicating structural failure. The vehicle has been taken off the road due to safety concerns. Addressing this will likely require professional frame repair or replacement, which is a major undertaking.

Your 4Runner's frame has developed rust damage, and the sway bar has come loose from the frame as a result. This can affect your vehicle's stability and handling, especially during turns or uneven driving conditions. The repair will likely involve inspecting the frame for rust damage, treating or replacing corroded sections, and re-securing or replacing the sway bar.

When you brake from 20 mph, your seat rocks forward and then backward as you come to a stop, creating an unsafe feeling like the seat mount might break away from the floor. This suggests the seat mounting hardware may be loose or worn and needs to be inspected and secured.

Your 4Runner's frame is experiencing severe rust, and this rust continues to develop even after attempts to prevent it. Frame rust can compromise the structural integrity of your vehicle over time. Addressing this typically involves rust removal, treatment, and protective coatings to prevent further deterioration.
