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 front suspension upper control arm bolts on a 2010-2018 Dodge RAM-3500?

The torque specification for the front suspension upper control arm bolts is typically 125 ft-lbs (169 Nm). Always refer to the vehicle’s service manual for the exact specifications, as they may vary depending on the model year and specific suspension configuration.

Q2

How often should I check the torque on my suspension bolts?

It is recommended to check the torque on suspension bolts every 15,000 miles or after any significant impact, such as hitting a pothole or curb. Regular inspections ensure the bolts remain secure and prevent potential suspension component failure.
