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 drivetrain bolts?
Why are torque specifications important for drivetrain bolts?
Correct torque ensures proper clamping force, preventing bolts from loosening due to vibration and stress, and avoids damage to threads and components. Under-torquing can lead to parts coming loose, while over-torquing can stretch or break bolts or damage components. For example, over-tightening the driveshaft bolts can deform the mounting flanges or damage the threads in the differential.
Q2 What happens if I don't have a torque wrench?
What happens if I don't have a torque wrench?
While using a torque wrench is highly recommended, you can estimate torque by 'feeling', but this is not precise and risky. A torque wrench ensures accuracy, preventing damage and ensures proper fastening. Borrowing or renting a torque wrench is crucial for safety. Using improper torque can result in premature failure of the component or even a safety hazard.
Q3 Do I need to replace bolts after removing them?
Do I need to replace bolts after removing them?
It's often recommended to replace torque-to-yield (TTY) bolts, especially those on critical components like the driveshaft or transmission mounts, as they stretch when tightened to a specific torque. Reusing TTY bolts can result in inaccurate clamping and failure. For standard bolts, inspect for damage and replace if necessary. Check your service manual.
Q4 Should I use thread locker on drivetrain bolts?
Should I use thread locker on drivetrain bolts?
Thread locker (e.g., Loctite) is recommended on some drivetrain bolts, particularly those prone to vibration, such as driveshaft bolts and transmission mounting bolts. Check your service manual for recommendations and use the correct type (e.g., medium strength for most applications, high strength for components that should never loosen). Apply thread locker sparingly on clean, dry threads.
Q5 What should I do if I strip a bolt or damage threads?
What should I do if I strip a bolt or damage threads?
If a bolt is stripped or threads are damaged, stop immediately. Attempting to force the bolt further can cause more damage. Repairing threads requires specialized tools like taps and dies. Use correct size and type tools to avoid further damage. If the stripped bolt is in the transmission or differential case consider professional help.
