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?
Correct torque is crucial for drivetrain bolts to ensure proper clamping force. Under-tightening can lead to loosening, component failure, and vibrations. Over-tightening can damage bolts, threads, or components and can cause premature wear or failure. For example, an improperly torqued CV axle bolt could lead to axle separation while driving, causing a loss of power and control.
Q2 What happens if I don't use a torque wrench?
What happens if I don't use a torque wrench?
Without a torque wrench, it's very difficult to achieve the correct torque. You risk under- or over-tightening, which can lead to the issues mentioned previously. Relying on feel alone is not accurate enough for critical drivetrain components. For example, overtightening the differential case bolts can crush the case and destroy the internal bearings.
Q3 Where can I find the specific torque specs for my 2022-present Acura ILX drivetrain components?
Where can I find the specific torque specs for my 2022-present Acura ILX drivetrain components?
The most reliable source for accurate torque specifications is the official Acura ILX service manual. These specs can vary slightly depending on specific models or sub-systems. You can purchase a service manual online or access some specifications through subscription services like ALLDATA. Some online forums may share information, but always double-check against the official manual before use. Always be specific when searching for the specs, such as '2022 Acura ILX transmission mounting bolts torque' vs simply 'Acura ILX torque specifications'.
Q4 Do I need to replace the bolts every time I remove them when working on the drivetrain?
Do I need to replace the bolts every time I remove them when working on the drivetrain?
While not always required, some bolts, particularly those subject to high stress or torque-to-yield (TTY) designs, are recommended for replacement after removal. Check your service manual for specific replacement recommendations for each bolt you are working with in the drivetrain. For example, some axle shaft bolts or differential carrier bolts are single-use.
