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 drivetrain bolts on a 2009-2014 Volkswagen Routan?

The torque specifications for drivetrain bolts vary depending on the specific component. For example, the axle flange bolts typically require 70-80 ft-lbs, while transmission mounting bolts may require 40-50 ft-lbs. Always refer to the official service manual for precise values.

Q2

How often should I check the torque on drivetrain bolts?

It is recommended to check the torque on drivetrain bolts during routine maintenance, such as every 30,000 miles or after any major drivetrain repair. Loose bolts can lead to vibrations, noise, or even component failure.

Q3

Can I reuse drivetrain bolts after removal?

Reusing drivetrain bolts is generally not recommended, as they are often torque-to-yield bolts designed for one-time use. Reusing them can compromise their integrity and lead to failure. Always replace with new bolts as specified by the manufacturer.

Environmental Considerations

  • Maintain proper protective coatings

Salt Exposure

Effects:
  • Rapid corrosion development
  • Thread damage
  • Seized fasteners
Prevention:
  • Regular underbody washing
  • Use of sacrificial anodes where appropriate
