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 recommended torque specification for the suspension bolts on a 2008-2014 Dodge Avenger?

The recommended torque specification for the suspension bolts on a 2008-2014 Dodge Avenger is 70-80 ft-lbs for the upper control arm bolts, 80-90 ft-lbs for the lower control arm bolts, and 100-110 ft-lbs for the strut mount bolts. However, it's always best to consult the owner's manual or a repair manual for specific torque specifications.

Q2

Why is it important to follow the recommended torque specifications for suspension bolts?

Following the recommended torque specifications for suspension bolts is crucial to ensure the safety and stability of the vehicle. Over-torquing can damage the threads or strip the bolts, while under-torquing can lead to loose bolts and compromised suspension performance. This can result in uneven tire wear, reduced handling, and increased risk of accidents.

Q3

How often should I check and maintain the suspension bolts on my 2008-2014 Dodge Avenger?

It's recommended to check the suspension bolts every 12,000 to 15,000 miles or during routine maintenance. Look for signs of wear, corrosion, or damage, and tighten or replace the bolts as needed. Additionally, if you notice any unusual noises, vibrations, or handling issues, have the suspension system inspected and maintained by a qualified mechanic.

Environmental Considerations

  • Use temperature-resistant thread lockers
  • Consider re-torquing after heat cycles

Humidity and Corrosion

Covers: Rust Prevention, Salt Exposure, Moisture Control

Moisture and corrosion can affect fastener integrity and torque values

High Humidity

Effects:
  • Accelerated corrosion formation
  • Reduced friction coefficient
  • Potential thread seizing
Prevention:
  • Use corrosion-resistant fasteners
