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 is using the correct torque specification so important for suspension bolts?
Why is using the correct torque specification so important for suspension bolts?
Correct torque ensures proper clamping force. Over-tightening can damage threads, stretch bolts beyond their yield point, and even distort suspension components. Under-tightening can lead to loosening, component failure, and dangerous loss of control. For example, a wheel bearing bolt torqued incorrectly can result in premature bearing failure.
Q2 What happens if I don't have a torque wrench?
What happens if I don't have a torque wrench?
While it's possible to tighten bolts without one, it's strongly discouraged for suspension components. A torque wrench is the only accurate way to achieve proper clamping force. Without one, you're guessing, which is unsafe. Incorrectly tightened bolts can lead to component failure and increase the risk of an accident. If you don't have one, borrowing or renting one is highly recommended.
Q3 Should I use new bolts when working on the suspension?
Should I use new bolts when working on the suspension?
It's highly recommended to replace torque-to-yield bolts. These bolts are designed to stretch when tightened and should not be reused. Using a used torque-to-yield bolt can lead to improper clamping force and compromise safety. For other bolts, inspect them for damage or stretching and replace as necessary.
Q4 Do I need to re-torque the suspension bolts after driving?
Do I need to re-torque the suspension bolts after driving?
Yes, it's a good practice to re-torque suspension bolts after approximately 50-100 miles of driving, especially after a major component replacement. This is because the components settle, and the bolts may loosen slightly. Re-torquing helps ensure they remain secure, maintaining proper handling and safety.
Q5 Can I use threadlocker on suspension bolts?
Can I use threadlocker on suspension bolts?
Use threadlocker only when specified in the vehicle's service manual. Certain components may require threadlocker to prevent loosening, but using it where not specified can lead to incorrect torque readings or make future removal difficult. Always consult the manufacturer's recommendations for specific torque and threadlocker requirements.
