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.
Prevention:
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.
Prevention:
Follow the manufacturer's specified torque sequence pattern.
Dirty Threads
Dirt, rust, or old thread locker can affect torque readings and proper fastener tension.
Prevention:
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.
Prevention:
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.
Prevention:
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 IS the torque specification for the wheel lug nuts on a 2006-2010 Volkswagen Passat?
Q1
What IS the torque specification for the wheel lug nuts on a 2006-2010 Volkswagen Passat?
110 ft-lbs (150 Nm)
Q2 What IS the recommended tightening sequence for the wheel lug nuts?
Q2
What IS the recommended tightening sequence for the wheel lug nuts?
Tighten the lug nuts in a star pattern, starting with the lug nut opposite the valve stem. Tighten each lug nut to 50 ft-lbs (68 Nm) in this pattern, then return and tighten each lug nut to the final specification of 110 ft-lbs (150 Nm).
Q3 What type of torque wrench should I use to tighten the wheel lug nuts?
Q3
What type of torque wrench should I use to tighten the wheel lug nuts?
Use a calibrated torque wrench with a range that covers the specified torque value (110 ft-lbs or 150 Nm). Ensure the torque wrench IS properly maintained and calibrated according to the manufacturer's instructions.
Q4 IS it acceptable to use an impact wrench to tighten the wheel lug nuts?
Q4
IS it acceptable to use an impact wrench to tighten the wheel lug nuts?
No, it IS not recommended to use an impact wrench to tighten wheel lug nuts as it can over-tighten the nuts, potentially leading to damage or stripping of the threads.
Q5 Should I lubricate the threads of the wheel lug nuts before tightening them?
Q5
Should I lubricate the threads of the wheel lug nuts before tightening them?
No, it IS not recommended to lubricate the threads of the wheel lug nuts. Lubrication can reduce the friction between the nut and the wheel, potentially leading to inaccurate torque readings and a risk of under-tightening the nuts.
Q6 How often should I check the torque of the wheel lug nuts?
Q6
How often should I check the torque of the wheel lug nuts?
Check the torque of the wheel lug nuts after every tire rotation or tire change. Regularly check the torque, especially if the vehicle has been driven in rough or off-road conditions.
