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?
Incorrect torque settings can lead to premature loosening, potentially causing catastrophic failures in the drivetrain. Over-torquing can damage threads and components, while under-torquing leaves bolts vulnerable to vibration and movement, which can cause noise, leaks, and ultimately, failure. Proper torque ensures the correct clamping force, preventing these issues and extending the lifespan of the drivetrain.
Q2 What if I don't have a torque wrench?
What if I don't have a torque wrench?
Using a regular wrench to tighten bolts to a *feeling* is insufficient. It's highly recommended to use a torque wrench for all drivetrain bolts. Improper tightening can lead to significant damage and safety risks. If you do not own a torque wrench, consult a qualified mechanic for assistance.
Q3 How often should I check the torque on drivetrain bolts?
How often should I check the torque on drivetrain bolts?
Regular inspections of drivetrain bolt torque are crucial, especially after any significant work done on the vehicle, such as engine or transmission repairs, or after extended periods of operation in harsh conditions (e.g., towing, off-road driving). A general recommendation is to check them every 10,000 miles or as outlined in the owner's manual. Significant vibrations or unusual noises should also prompt a check.
Q4 What are the different types of torque wrenches available, and which is best for the Hyundai Accent?
What are the different types of torque wrenches available, and which is best for the Hyundai Accent?
There are various types of torque wrenches, including dial, digital, and beam-type. A digital torque wrench is generally recommended for its accuracy and ease of use. Refer to your specific Hyundai Accent's torque specifications for the recommended specifications and range.
