How to Install Eccentric Bolts on a Car?
3 Answers
1. When installing eccentric bolts on a car, if the camber angle is large, the belly of the bolt should face inward; if the camber angle is small, the belly of the bolt should face inward. Adjust while measuring. 2. Toe-out indicates a negative camber angle, while toe-in indicates a positive camber angle. If the eccentric bolt is on the lower control arm and the camber angle is negative, the belly should face outward; if positive, it should face inward. 3. Additional Information: The purpose of eccentric bolts is to adjust angles during wheel alignment. For example, if the wheel camber angle exceeds the standard range, it can only be adjusted using eccentric bolts. Using eccentric bolts ensures proper wheel alignment, prevents tire wear, and maintains safety.
I've installed automotive eccentric bolts a few times, and it's quite interesting - somewhat complex but not too difficult. They're typically used for adjusting angles in wheel suspension to prevent excessive tire wear. I recommend preparing these tools first: a jack or lift to raise the vehicle and remove the wheel; then use a wrench or socket to loosen the original nuts and remove the old bolt. When installing the new eccentric bolt, make sure to align it properly with the hole, carefully rotate the eccentric part to the desired camber angle (you might need chalk marks for positioning). Tighten the nuts with a wrench, but avoid over-torquing to prevent thread stripping. Finally, a four-wheel alignment check is mandatory to ensure correct angles before driving - don't skip this safety step or your steering might pull dangerously. The whole process takes about half an hour; beginners can watch tutorial videos or get assistance.
From my experience in car repair, the key to installing eccentric bolts lies in precision and tool compatibility. First, stabilize the vehicle using a lift to raise it, then remove the wheel to expose the suspension bolt points. For tools, prepare a specialized socket and torque wrench to ensure no mistakes when loosening the nuts. After aligning the new bolt with the hole, adjust the eccentric angle—typically for adjusting wheel camber or toe—and tighten to the manufacturer's specifications, usually around 100Nm. After installation, check for any misalignment; it's best to have a friend confirm the angle or use a level for assistance. Once completed, a full suspension test is recommended to prevent accidents caused by loosening. Remember, having the right tools makes the job much easier—don't cut corners with a regular wrench, as details determine safety.
