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 body bolts?
Why are torque specifications important for body bolts?
Incorrect torque on body bolts can lead to various issues, including potential structural weakness, premature failure of fasteners, and even safety hazards. Over-torquing can strip the threads or damage the bolt/nut, while under-torquing allows the fasteners to loosen and vibrate, leading to noise, rattles, and eventually, complete failure. Imagine a loose door handle that rattles; this is a real-world example of under-torquing.
Q2 What if I don't have the correct torque wrench?
What if I don't have the correct torque wrench?
Using a torque wrench is crucial for ensuring the proper tightening of body bolts. If you don't have the correct torque wrench, using a general tightening method is insufficient. Consult the official Hyundai service manual for the specific torque specifications.
Q3 How often should I check body bolt torque?
How often should I check body bolt torque?
Regular inspection and tightening of body bolts are recommended during routine maintenance, especially after any significant repairs or modifications to the vehicle's body. Check your owner's manual for suggested maintenance intervals. A common example is after suspension work, where body panel alignment and bolt stress can change.
Q4 What happens if a body bolt breaks?
What happens if a body bolt breaks?
A broken body bolt can compromise the structural integrity of the vehicle's body panels. This can lead to misalignment, causing rattles and potential safety issues. It is important to have a broken bolt repaired immediately by a qualified mechanic to restore the vehicle's structural integrity.
