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 correct torque specifications important for drivetrain bolts?
Why are correct torque specifications important for drivetrain bolts?
Correct torque is crucial to ensure proper clamping force between components, preventing loosening, vibration, and potential component failure. Over-tightening can damage threads or bolts, while under-tightening can lead to slippage and premature wear. For example, insufficiently torqued driveshaft bolts might cause vibrations, leading to damage to the transmission or differential.
Q2 What happens if I over-tighten a drivetrain bolt?
What happens if I over-tighten a drivetrain bolt?
Over-tightening can stretch or break the bolt, damage threads in the mating component (like the transmission housing), or crush the gasket/seal. This can lead to leaks, component failure, and potentially expensive repairs. Imagine over-tightening the bolts holding the differential; you could crack the housing or strip the threads, requiring a complete replacement.
Q3 What happens if I under-tighten a drivetrain bolt?
What happens if I under-tighten a drivetrain bolt?
Under-tightening can lead to parts coming loose, causing vibrations, noises, and ultimately component failure. For example, loose guibo bolts can lead to severe vibrations and stress on the driveshaft and surrounding components. It can also create play in the drivetrain, leading to accelerated wear.
Q4 Do I need to use new bolts when working on the drivetrain?
Do I need to use new bolts when working on the drivetrain?
While not always mandatory, it is highly recommended to replace stretch bolts, self-locking nuts, and fasteners that have been torqued to yield. These fasteners lose their clamping force after being used and are not designed for reuse. For example, some driveshaft bolts and flywheel bolts are one-time use only. Using new fasteners ensures proper clamping force and safety.
Q5 Should I use thread locker on drivetrain bolts?
Should I use thread locker on drivetrain bolts?
Thread locker (like Loctite) is recommended on certain drivetrain fasteners, particularly those subject to vibration and high loads. Refer to the repair manual for specific recommendations. For example, thread locker is often recommended for bolts securing the transmission to the engine, or the flex disc to the output flange.
