Common Mistakes to Avoid
Common Mistakes to Avoid
Over-tightening
Exceeding the specified torque value can stretch or break fasteners, damage threads, or crack components.
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.
Follow the manufacturer's specified torque sequence pattern.
Dirty Threads
Dirt, rust, or old thread locker can affect torque readings and proper fastener tension.
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.
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.
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 is it important to use the correct torque specifications for suspension bolts?
Why is it important to use the correct torque specifications for suspension bolts?
Using the correct torque specifications ensures proper clamping force, preventing bolts from loosening during driving, which could lead to component failure, premature wear, or loss of vehicle control. Overtightening can damage the bolt or the components, and under-tightening will cause movement, impacting stability.
Q2 What happens if I overtighten a suspension bolt?
What happens if I overtighten a suspension bolt?
Overtightening can stretch or break the bolt, strip the threads in the receiving component, or damage bushings and mounting points. This can lead to compromised structural integrity and potentially require costly repairs. For example, overtightening a lower control arm bolt can damage the bushing, needing early replacement.
Q3 Can I reuse old suspension bolts?
Can I reuse old suspension bolts?
It's generally not recommended to reuse torque-to-yield (TTY) bolts, as they stretch when tightened and may not provide the correct clamping force the second time. Standard bolts can sometimes be reused if they are not damaged or corroded. However, it is always best practice to use new fasteners whenever performing suspension work. If reusing, carefully inspect bolts for signs of wear, corrosion, or damage.
Q4 Should I use a torque wrench when working on my suspension?
Should I use a torque wrench when working on my suspension?
Absolutely. Using a torque wrench is essential to achieving the specified torque accurately. Relying on feel alone can lead to overtightening or under-tightening, compromising the suspension's integrity. For example, tightening the upper control arm mounting bolts to 'hand tight' is never recommended.
Q5 Do I need to torque bolts with the vehicle on the ground or in the air?
Do I need to torque bolts with the vehicle on the ground or in the air?
Some suspension bolts, especially those securing bushings, should be tightened with the vehicle at its normal ride height (on the ground or on ramps). This prevents preloading the bushings and ensures proper function and longevity. For example, lower control arm mounting bolts are typically torqued when the suspension is loaded.
Q6 What happens if I lose my torque spec sheet?
What happens if I lose my torque spec sheet?
If you lose your torque specifications, consult a reliable service manual specific to your 2007-2014 Cadillac Escalade. Additionally, online reputable forums can assist, however, always try to verify from multiple sources. Another good resource can be the manufacturer.
