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 my 2016-Present Ram 5500?

The recommended torque specification for the suspension bolts on your 2016-Present Ram 5500 is 120 ft-lbs (163 Nm) for the upper control arm bolts, 100 ft-lbs (136 Nm) for the lower control arm bolts, and 80 ft-lbs (109 Nm) for the shock absorber bolts. It's essential to consult your owner's manual or a trusted repair manual for specific torque values, as they may vary depending on the specific suspension component and configuration.

Q2

How often should I check and maintain the suspension bolts on my Ram 5500?

It's recommended to check the suspension bolts every 12,000 to 15,000 miles (19,312 to 24,140 km) or as specified in your owner's manual. Regular maintenance includes inspecting the bolts for signs of wear, corrosion, or damage, and tightening them to the recommended torque specification. Failure to maintain the suspension bolts can lead to reduced vehicle stability, uneven tire wear, and increased risk of component failure.

Q3

Can I use a impact wrench to tighten the suspension bolts on my Ram 5500?

While an impact wrench can be convenient, it's not recommended for tightening suspension bolts. Impact wrenches can apply excessive force, which can damage the threads or strip the bolts. Instead, use a torque wrench to ensure accurate and controlled tightening. This will help prevent damage to the suspension components and ensure proper torque values are achieved.

Environmental Considerations

  • 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
  • Potential thread seizing
Prevention:
  • Use corrosion-resistant fasteners
  • Apply appropriate anti-seize compounds
  • Maintain proper protective coatings

Salt Exposure

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

Seasonal Maintenance

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
