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 2011-2014 Volkswagen Passat?
What are the torque specifications for the suspension bolts on a 2011-2014 Volkswagen Passat?
The torque specifications vary depending on the specific suspension component. For example, the front strut-to-knuckle bolts should be torqued to 70 Nm (52 lb-ft) plus an additional 90° turn, while the rear shock absorber lower mounting bolt requires 90 Nm (66 lb-ft). Always refer to the official Volkswagen repair manual for precise values.
Q2 Can I reuse suspension bolts after removal?
Can I reuse suspension bolts after removal?
No, suspension bolts are often designed as stretch bolts and should not be reused. Reusing them can compromise the structural integrity of the suspension system. Always replace them with new, OEM-specified bolts to ensure safety and proper torque application.
Q3 What happens if I under-torque or over-torque suspension bolts?
What happens if I under-torque or over-torque suspension bolts?
Under-torquing can lead to loose components, causing noise, vibration, and potential failure. Over-torquing can strip threads, damage components, or cause stress fractures. Both scenarios can compromise vehicle safety and handling. Always use a calibrated torque wrench and follow manufacturer specifications.
