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 it important to use the correct torque specifications for body bolts?
Why is it important to use the correct torque specifications for body bolts?
Using the correct torque ensures that body panels and components are securely fastened without being over-tightened (which can damage threads or panels) or under-tightened (which can lead to loosening, rattles, or potential safety issues). Proper torque ensures consistent clamping force, preventing movement and maintaining structural integrity. For example, an improperly torqued bumper could detach during an impact.
Q2 What happens if I over-torque a body bolt?
What happens if I over-torque a body bolt?
Over-torquing can stretch or break bolts, damage the threads in the body panels, and potentially distort the panel itself. This can lead to leaks, rust, and require costly repairs, such as drilling out broken bolts or replacing body panels. A common sign is if the panel is visibly deformed or if the bolt spins without tightening.
Q3 What happens if I under-torque a body bolt?
What happens if I under-torque a body bolt?
Under-torquing a bolt can lead to the bolt loosening over time due to vibration, causing rattles, misaligned panels, water leaks, or even panel detachment. This can create unsafe conditions, especially for components like bumpers or fenders. You might notice a loose panel or a rattling noise originating from the affected area.
Q4 Do I need to replace body bolts every time I remove them?
Do I need to replace body bolts every time I remove them?
While not always necessary, it's recommended to inspect body bolts for damage (stripped threads, corrosion, or stretching) after removal. If any damage is found, replace them. Also, some manufacturers may recommend replacing specific bolts if they are designed for one-time use. Typically, self-tapping bolts or bolts showing signs of excessive wear should be replaced. When in doubt, err on the side of caution and replace.
Q5 Do torque specs change based on whether the bolt is going into metal or plastic?
Do torque specs change based on whether the bolt is going into metal or plastic?
Yes, torque specifications can differ. Bolts going into metal typically have higher torque values than bolts going into plastic or composite materials. When attaching parts to plastic, over-torquing can crack or damage the plastic. Always consult the specific torque specifications for each location. You might find lower torque values when attaching side mirrors or grilles which use plastic mounts.

Technical Service Bulletins
Body Panel Alignment Issues
1998-04-15Some models may experience slight body panel alignment issues due to variations in manufacturing. This often occurs at high-stress points.
Resolution: Inspect all mounting bolts, paying close attention to body panel overlap. Ensure proper torque is achieved to minimize misalignment. If misalignment persists, consider adding shims or adjusting the panel slightly within the mounting holes.
Radiator Support Bracket Corrosion
1999-11-01Corrosion may occur at radiator support mounting points due to exposure to the elements, leading to loosen bolts.
Resolution: Inspect radiator support brackets and surrounding areas for corrosion. Clean and apply anti-corrosion coating as needed. Replace heavily corroded brackets. Ensure radiator support bolts are torqued to the specified values (30-40 Nm).
Bumper Cover Fastener Loosening
2000-07-20Bumper cover fasteners may loosen due to road vibration, and/or impact, particularly after impacts. This leads to improper fit or rattling.
Resolution: Check the torque on all bumper mounting bolts and any clips and fasteners that attach the cover. Tighten to the specified values (35-45 Nm). Check these more frequently after a minor accident.
