How to Adjust an Off-Center Steering Wheel in a Truck?

Truck steering wheel misalignment can be adjusted by following these steps: 1. Turn the vehicle's steering wheel fully to the right to expose the rear of the left front wheel; 2. Loosen the nut, then rotate the left tie rod clockwise to shorten it or counterclockwise to lengthen it; 3. Turn the steering wheel fully to the left to expose the rear of the right front wheel; 4. Loosen the nut, then rotate the right tie rod clockwise to shorten it or counterclockwise to lengthen it. The vehicle steering wheel connects to the steering column via splines, converting the driver's applied force at the wheel rim into torque transmitted to the steering shaft. Common steering wheel buttons in passenger cars include: 1. SET for speed setting; 2. CNL for cruise control cancellation; 3. RES for cruise control resumption; 4. Up/Down for volume adjustment.
We truck drivers usually check the tire pressure first when we notice the steering pulling to one side. Insufficient air pressure on both sides can also cause the steering to drag. Park on level ground and observe how many degrees the steering wheel is off, then check if there's uneven wear on both tires. If the front tires show uneven wear, it's likely you'll need to adjust the tie rods. I usually loosen the dust boot clamp and slowly turn the tie rod screw with a wrench—half a turn to the left and half a turn back to the right—testing the alignment as I go. Be careful not to turn it too much at once. After adjusting, you'll need to get a wheel alignment done, or your new tires will be ruined in two months. Also, remember to check the steering gear bushing—if it's cracked, the steering wheel will wobble.
Last time I drove long-distance, I noticed the steering wheel was off by 15 degrees to the left, and it took me three days to find the issue. First, get under the car and check if the tie rod is bent or if the ball joint is leaking. Lift the car and shake the tires to listen for any clunking noise—if there is, the bearings are loose. If it's just a tie rod problem and you have the tools and experience, you can fix it yourself: straighten and lock the steering wheel, then measure the length of both tie rods with a tape measure. If the difference exceeds 3mm, an adjustment is needed. Also, tighten the universal joint screws on the steering column—play in that area is often overlooked. After adjustments, be sure to test on a gravel road; if the steering wheel kicks back, the toe-in is incorrect.
