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 What are the torque specifications for the suspension bolts on a 2019-Present Volkswagen Touareg?
What are the torque specifications for the suspension bolts on a 2019-Present Volkswagen Touareg?
The torque specifications for the suspension bolts vary depending on the specific component. For example, the front suspension strut-to-steering knuckle bolt typically requires 90 Nm + 90° (torque-to-yield), while the rear suspension lower control arm bolt may require 120 Nm + 90°. Always refer to the official Volkswagen repair manual for precise specifications.
Q2 How often should suspension bolts be checked for proper torque?
How often should suspension bolts be checked for proper torque?
Suspension bolts should be checked during routine maintenance, such as tire rotations or suspension inspections, or after any suspension-related repairs. It is also recommended to check them if you notice unusual noises, vibrations, or handling issues while driving.
Q3 Can I reuse suspension bolts after removal?
Can I reuse suspension bolts after removal?
Some suspension bolts, especially torque-to-yield bolts, are designed for one-time use and must be replaced after removal. Reusing these bolts can compromise the structural integrity of the suspension system. Always consult the repair manual to determine if a bolt is reusable.
