Common Mistakes to Avoid
Common Mistakes to Avoid
Over-tightening
Exceeding the specified torque value can stretch or break fasteners, damage threads, or crack components.
Always use a calibrated torque wrench and follow specifications exactly.
Incorrect Torque Sequence
Tightening bolts in the wrong order can cause uneven pressure distribution and potential leaks or damage.
Follow the manufacturer's specified torque sequence pattern.
Dirty Threads
Dirt, rust, or old thread locker can affect torque readings and proper fastener tension.
Clean and inspect all threads before assembly. Use new thread locker if specified.
Reusing TTY Bolts
Torque-to-yield bolts are designed to stretch and must not be reused.
Always replace TTY bolts with new ones. They are single-use only.
Dry vs. Lubricated
Not accounting for whether torque specs are for dry or lubricated fasteners can lead to incorrect tension.
Check if specs are for dry or lubricated threads. Use specified lubricant when required.

Frequently Asked Questions
Find answers to common questions about torque specifications
Q1 Why are torque specifications important for suspension bolts?
Why are torque specifications important for suspension bolts?
Improper torque on suspension bolts can lead to premature failure. Under-torqued bolts can loosen, potentially causing the suspension to fail during operation, leading to a crash. Over-torqued bolts can damage the threads in the component, leading to the same potential failure. Precise torque ensures the bolts are sufficiently tight, preventing movement and maintaining proper suspension alignment and function.
Q2 What if I don't have the correct torque wrench?
What if I don't have the correct torque wrench?
Using a wrench that doesn't accurately measure torque is dangerous. A manual wrench can't provide the precise force needed. Contact a qualified mechanic for assistance if you lack the correct tools. Using the incorrect torque can damage the vehicle's suspension and potentially lead to safety issues.
Q3 How often should I check the torque on my suspension bolts?
How often should I check the torque on my suspension bolts?
Suspension bolts should be checked periodically, especially after any suspension work, major repairs, or significant driving events (like a collision or driving over a pothole). Recommended intervals vary based on driving conditions and mileage. Consult your owner's manual for specific maintenance schedules, but a good rule of thumb is at least annually or every 15,000 miles.
Q4 What happens if a suspension bolt comes loose?
What happens if a suspension bolt comes loose?
A loose suspension bolt can cause vibrations, a pull in one direction, and a grinding noise. It can lead to poor handling, unpredictable driving behavior, and potentially serious accidents. The vehicle might exhibit a noticeably lower ride height on one side.
