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 drivetrain bolts?
Why is using the correct torque specification so important for drivetrain bolts?
Using the correct torque specification is crucial for several reasons. Under-tightening can lead to bolts loosening over time, causing component failure, noise, and vibrations, which can be dangerous, especially in the drivetrain. Over-tightening can stretch or break bolts, damage threads in components, or distort housings, resulting in expensive repairs and potential safety issues. Proper torque ensures the correct clamping force, preventing movement between connected parts and ensuring reliable performance.
Q2 What happens if I don't have a torque wrench?
What happens if I don't have a torque wrench?
While it’s highly recommended to use a torque wrench for accurate tightening, if one is not available, extreme caution is required. You can try tightening to 'snug', but never overtighten. It is better to err on the side of less torque. However, you MUST verify the torque with a properly calibrated torque wrench as soon as possible. Driving the vehicle with improperly torqued bolts can lead to serious issues. You should aim to borrow or rent a torque wrench before any significant driving.
Q3 How often should I check the torque on my drivetrain bolts?
How often should I check the torque on my drivetrain bolts?
Generally, it's a good practice to re-check the torque on drivetrain bolts after any service that involves their removal or loosening. Additionally, for critical components, check after the first 50-100 miles of driving, then again at your next scheduled oil change. This is particularly relevant for new installations or after significant vibration. Regular visual inspection for loose fasteners or leaks can also help identify potential issues.
Q4 Can I reuse drivetrain bolts?
Can I reuse drivetrain bolts?
Whether you can reuse drivetrain bolts depends on the bolt type and its condition. Some bolts, particularly those used for critical applications or those with a stretch-to-yield design, should be replaced every time they are loosened. For less critical areas, carefully inspect bolts for any damage, including stretched threads, corrosion, or head deformities. When in doubt, it's always best to replace the bolt with a new one that meets manufacturer specifications. Consult your vehicle's service manual or a trusted source for information regarding your specific bolts.
