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 What are the torque specifications for the drivetrain bolts on a 2001 Hyundai XG300?
What are the torque specifications for the drivetrain bolts on a 2001 Hyundai XG300?
The torque specifications for the drivetrain bolts on a 2001 Hyundai XG300 vary depending on the specific component. For example, the axle nut typically requires 180-220 ft-lbs, while transmission-to-engine bolts may require 45-55 ft-lbs. Always refer to the manufacturer's service manual for precise values.
Q2 How often should I check the torque on drivetrain components?
How often should I check the torque on drivetrain components?
It is recommended to check the torque on drivetrain components during routine maintenance, such as oil changes or tire rotations, or after any work involving the drivetrain. For example, if you recently replaced a CV axle, recheck the axle nut torque after driving 50-100 miles to ensure it remains secure.
Q3 Can I reuse drivetrain bolts, or should they be replaced?
Can I reuse drivetrain bolts, or should they be replaced?
Some drivetrain bolts, such as axle nuts, are designed for one-time use and should be replaced after removal. Others, like transmission-to-engine bolts, can be reused if they are in good condition and not stretched or damaged. Always inspect bolts for wear and consult the service manual for guidance.
