This Apex Chassis tie rod adjusting sleeve is beefed up to prevent deflection under hard steering inputs in rough road conditions. Adjusting sleeves are a common weak spot, and as the lower quality units wear, they distort the vehicle alignment causing greater tire wear, odd steering feel and lower fuel economy as the front tires 'fight' each other. Another common issue is they get stuck in place from dirt and corrosion, which inevitably leads to distortion as a person tries to heat it and beat it into submission. If you run into any of these problems, it's time for a new tie rod adjusting sleeve from Apex Chassis.
