What is the installation method for automotive eccentric bolts?

Eccentric bolt installation method: First, align the protruding part of the copper piece outward, with the shorter side tightly against the inside of the eccentric bolt, then tighten it. Detailed explanations about the functions of eccentric bolts are as follows: 1. Eccentric bolts are commonly used in automobiles, and their installation does not increase the stress on the lower bolts. 2. Eccentric bolts are primarily used to adjust the camber angle of the wheels and the height difference between the left and right wheels. 3. Eccentric bolts mainly adjust the four-wheel alignment, utilizing the physical principles of inclined circular rotation and friction to secure mechanical components. 4. If the wheel camber angle exceeds the standard usage range, adjustment using eccentric bolts is necessary to ensure normal wheel data, effectively avoiding tire wear.

I've installed eccentric bolts several times before, the kind used for adjusting the suspension system. The necessary tools include a jack, wrenches, and a torque wrench. After lifting the car and removing the wheel, locate the installation position. The bolt is eccentric, so extra care is needed to align the holes properly—don't force it. Clean any grease or dirt around the bolt holes to prevent dust from affecting the adjustment and causing loosening. After installation, hand-tighten to initially secure the position, then use a wrench to adjust to the precise angle. It usually takes several attempts to align the center correctly. Once the position is confirmed, fully tighten the nut with the specified torque wrench. Don’t forget to lower the car afterward to measure the wheel track and take a short drive to check for balance, avoiding severe tire wear or steering wheel vibration later. Regular maintenance of the front wheels is recommended, and when replacing bolts, inspect surrounding components like bushings for signs of aging. It’s not difficult but does take time.

Installing eccentric bolts? As someone who frequently handles such car repairs, I emphasize a meticulous process: lift the car, remove the wheel, and clean the mounting surface to remove rust and oil. Ensure all tools are ready, including a universal wrench, eccentric adjustment tool, and torque wrench. The steps involve loosening the old part, replacing it with a new bolt, paying attention to the precise orientation of the eccentric part, manually screwing it in for alignment, and avoiding excessive force to prevent thread damage. Then, fine-tune the position to ensure accurate suspension geometry, and tighten the nut to the manufacturer's specified torque value, typically 20-40 Nm, to prevent loosening and unstable handling. Afterward, a road test is essential—if any abnormal noise occurs, rework is needed. Also, remind to use high-quality bolts, as inferior ones can easily lead to safety issues, and inspect the condition of the chassis components as well.

I'm just an ordinary car owner. Last time, I asked a friend to help replace the eccentric bolts on the front wheels. The method isn't complicated: first, use a jack to lift the car and remove the wheel. A wrench is all you need for the tools, and clean the bolt holes. When installing, align the eccentric position of the bolt head, gently screw it into the hole, adjust a few times to the correct angle, and then tighten the fixing nut. My experience is not to force it yourself, as misalignment can easily cause steering issues. After installation, take a test drive to see if the steering pulls to one side or if there's abnormal tire wear. If there's a problem, get it fixed quickly. During regular maintenance, remember to check if the bolts are loose, which can extend their service life.
