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

Why are correct torque specifications important for suspension bolts?

Correct torque is crucial for suspension component integrity and safety. Under-tightening can lead to bolts loosening, causing instability, component failure, and potentially accidents. Over-tightening can stretch or break bolts, damage threads, and distort components, leading to premature wear or failure. Using a torque wrench ensures consistent and accurate bolt tension for reliable performance.

Q2

What happens if I overtighten a suspension bolt?

Overtightening a suspension bolt can cause several issues. It can stretch the bolt beyond its yield strength, weakening it permanently. This can lead to bolt failure over time. Overtightening can also crush bushings or distort mounting points, affecting suspension geometry and causing uneven tire wear. In extreme cases, the bolt can snap immediately. For example, over-tightening a lower control arm bolt could distort the bushing, leading to premature wear and changes in handling characteristics.

Q3

What happens if I undertighten a suspension bolt?

Undertightened suspension bolts can work themselves loose due to vibrations and loads experienced during driving. This can lead to clunking noises, steering issues, instability, and accelerated wear on suspension components. A loose bolt can shear off or fall out completely, which could cause significant safety issues and a loss of vehicle control. For instance, an under-tightened strut bolt can result in a knocking sound while driving and compromise the shock absorber's effectiveness.

Q4

Should I use new bolts when replacing suspension components?

It is generally recommended to use new bolts when replacing suspension components, especially critical ones. Many suspension bolts are torque-to-yield (TTY) or stretch bolts, which are designed for one-time use. These bolts deform slightly when tightened to their specified torque and are not intended for reuse. Reusing TTY bolts can lead to insufficient clamping force and potential failure. Even if a bolt isn't TTY, it can be beneficial to replace with new for the peace of mind.

Q5

Should I apply threadlocker to suspension bolts?

Threadlocker is typically not required for most suspension bolts on the RSX. However, if specified in the service manual or recommended by the manufacturer, it should be applied as directed. Always follow the service manual guidance. Applying threadlocker without proper cause could cause more issues than it solves. If no service manual is available, then the general practice for suspension should be no thread locker applied.

Environmental Considerations

Temperature, humidity, and seasonal effects on torque specifications

Temperature Effects

Includes: High Heat, Cold Weather, Thermal Cycling

Temperature can significantly impact torque values and fastener behavior

Cold Weather

Effects:
  • Increased material brittleness
  • Higher torque required due to thread contraction
  • Reduced thread lubricant effectiveness
Recommendations:
  • Allow components to warm to room temperature when possible
  • Consider using winter-grade thread lubricants
  • Check torque values more frequently during winter months

Hot Weather

Effects:
  • Thermal expansion of components
  • Decreased friction in threads
  • Accelerated lubricant breakdown
Recommendations:
  • Check torque when components are at normal operating temperature
  • 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

Spring

  • Inspect for winter damage
  • Clean and protect exposed fasteners
  • Check torque on critical components

Summer

  • Monitor heat-affected components
  • Check expansion-related loosening
  • Inspect cooling system mounts

Fall

  • Prepare for winter conditions
  • Apply corrosion protection
