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 suspension bolts?
Why are torque specifications important for suspension bolts?
Torque specifications are crucial to ensure proper clamping force. Overtightening can stretch or break bolts, while undertightening can lead to component loosening, resulting in poor handling, noise, and potential suspension failure. Using the correct torque creates a secure and safe assembly.
Q2 Do I need to replace bolts after loosening them?
Do I need to replace bolts after loosening them?
While not always necessary, it's good practice to replace any torque-to-yield bolts (TTY) after they've been loosened, as they are designed for single use. Many suspension bolts on the 2004-2008 TSX are not TTY but if they appear damaged, stretched, or corroded, replacement is highly recommended for safety and to achieve proper torque.
Q3 What type of torque wrench should I use?
What type of torque wrench should I use?
A click-type torque wrench is generally recommended for most suspension work. It provides an audible and tactile click when the desired torque is reached. Digital torque wrenches are also acceptable but are more expensive. Ensure the wrench is properly calibrated.
Q4 Should I apply any lubrication to the threads before tightening?
Should I apply any lubrication to the threads before tightening?
Generally, you should avoid adding lubrication to dry bolts because most torque specifications are for dry threads. Applying lubricant can result in overtightening and damage. However, some components, like sway bar bushings, may require specific lubricant. If you apply anti-seize to threads, the torque spec needs to be adjusted (typically lower).
Q5 What are the most common suspension bolts that get neglected on the TSX?
What are the most common suspension bolts that get neglected on the TSX?
The lower control arm bolts, the strut mounting bolts, and the rear trailing arm bolts are some of the most commonly neglected. They are often difficult to access and may be overlooked during inspections, leading to failure if not torqued properly.
