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 2018-Present Volkswagen Atlas?

The torque specification for drivetrain bolts on a 2018-Present Volkswagen Atlas varies depending on the specific bolt and component. For example, the axle flange bolts typically require 90 Nm (66 lb-ft) + an additional 90° turn, while the driveshaft-to-differential bolts may require 40 Nm (30 lb-ft). Always refer to the official Volkswagen service manual for precise specifications.

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 significant drivetrain work. Additionally, inspect them if you notice unusual noises, vibrations, or leaks, as these could indicate loose bolts.

Q3

Can I reuse drivetrain bolts, or should they be replaced?

Some drivetrain bolts, such as stretch bolts, are designed for one-time use and must be replaced after removal. Reusing these bolts can compromise their integrity and lead to failure. Always check the manufacturer's guidelines to determine if a bolt is reusable or requires replacement.

Environmental Considerations
