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 are proper torque specifications important for suspension bolts?
Why are proper torque specifications important for suspension bolts?
Correct torque is crucial for the safety and performance of your Cadillac Escalade's suspension. Under-torqued bolts can loosen over time, leading to component failure, noise, and instability. Over-torqued bolts can stretch or break, damaging the bolt and potentially the mating components. Both situations can compromise handling and increase the risk of accidents. Proper torque ensures the correct clamping force, keeping components securely fastened and functioning as designed.
Q2 What happens if I reuse torque-to-yield (TTY) bolts?
What happens if I reuse torque-to-yield (TTY) bolts?
Torque-to-yield (TTY) bolts are designed to stretch upon tightening and should *never* be reused. Reusing them will compromise their strength and clamping ability, potentially leading to failure. The threads can become deformed and not hold proper torque. Always replace TTY bolts with new ones to ensure a safe and proper repair. A common example is many control arm bolts, and these must always be replaced.
Q3 Do I need to use thread locker on suspension bolts?
Do I need to use thread locker on suspension bolts?
The need for thread locker varies by bolt location. Some suspension bolts are designed to be used with thread locker from the factory. Always consult the service manual for your specific Escalade year to verify the proper use of thread locker. Generally, bolts that are particularly prone to loosening, such as those in areas with high vibration, may require thread locker. If a bolt calls for threadlocker from the factory, it is essential to follow that procedure.
Q4 Should I torque suspension bolts with the vehicle on the ground or in the air?
Should I torque suspension bolts with the vehicle on the ground or in the air?
Generally, it's recommended to torque suspension bolts with the vehicle's weight on the suspension (i.e., on the ground, or with a weight equal to the vehicles resting weight on the suspension). When the suspension is hanging (i.e. in the air), the control arm bushings can be twisted and will be under pre-load when the vehicle is on the ground again, which can damage them and lead to premature wear or noise. This is because when the suspension is loaded, it settles into its operational position, and torquing in this position ensures proper alignment. Certain components, however, may require a raised torque procedure, so always consult the manual for instructions and requirements.
Q5 Are the torque specs in this document comprehensive for all suspension parts?
Are the torque specs in this document comprehensive for all suspension parts?
This document provides torque specifications for common suspension components, but it is *not* exhaustive. Consult the official Cadillac service manual for your specific model year and trim for the complete and accurate torque specifications. There are other bolts not explicitly mentioned here, and it is your responsibility to verify correct torque specifications before assembly.
