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 specification ensures that the body panels and components are securely fastened without being overstressed. Over-tightening can damage the bolts, threads, or the panels themselves, leading to cracks, deformation, or bolt failure. Under-tightening can cause the parts to loosen over time, leading to rattles, misalignments, and potential safety hazards. For example, a loose door hinge can cause the door to sag, making it difficult to close and potentially damaging the door latch.
Q2 What tools are needed to torque body bolts correctly?
What tools are needed to torque body bolts correctly?
You will need a calibrated torque wrench that measures in Newton-meters (Nm) or foot-pounds (lb-ft), depending on the specifications. You may also need sockets of the appropriate size for the bolts, and potentially extensions or swivels to reach bolts in difficult locations. Always ensure your torque wrench is in good working condition and within its calibration period. Using a non-calibrated or incorrect wrench will lead to incorrect torque values.
Q3 What if I don't have a torque wrench, can I just tighten the bolts by feel?
What if I don't have a torque wrench, can I just tighten the bolts by feel?
It's strongly discouraged to tighten body bolts by feel. 'Feel' is subjective and inconsistent, which can easily lead to over or under-tightening. Torque specifications are critical for the structural integrity and long-term reliability of the vehicle. For example, a bolt securing the fender might 'feel' tight, but actually be dangerously undertightened and vibrate loose later on. Renting or borrowing a torque wrench for this job is strongly recommended.
Q4 Are there any specific areas on the XTS body where torque is especially crucial?
Are there any specific areas on the XTS body where torque is especially crucial?
Yes, areas such as the door hinges, hood hinges, fender mounts, bumper brackets, and any structural body components are critical and require precise torque. These are areas where the fasteners must bear the weight of a component or maintain a proper alignment. For instance, incorrect torque on bumper bracket bolts can affect the integrity of the bumper cover and cause misalignment with other body panels.
Q5 Do I need to replace body bolts after removing them?
Do I need to replace body bolts after removing them?
While not always required, it's generally recommended to replace torque-to-yield (TTY) bolts. These bolts are designed to stretch upon tightening, and should not be reused. For other types of body bolts, always inspect them for damage, wear, or corrosion. It is always a good idea to replace any bolt that seems questionable. Also, it is very important to remove rust from bolts before reinstalling them, as rust can cause a false torque reading and lead to undertightening.
