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 using the correct torque specifications so important for suspension bolts?
Why is using the correct torque specifications so important for suspension bolts?
Using the correct torque specifications is crucial for suspension bolt integrity and safety. Under-torqued bolts can loosen over time, leading to component failure and loss of control. Over-torqued bolts can stretch, weaken, or even break, also leading to failure. Proper torque ensures that the bolts provide the designed clamping force, securing components and maintaining proper suspension geometry and operation.
Q2 What happens if I don't have a torque wrench?
What happens if I don't have a torque wrench?
While a torque wrench is highly recommended, if you don't have one, you should tighten the bolt with a standard wrench to a 'snug' point. Avoid over-tightening. Once you obtain a torque wrench, loosen the bolt and then re-torque to the specified value. 'Snug' is not precise and can vary; it should be considered a temporary fix only until a torque wrench can be used to finalize installation. Going to a local parts store or mechanic shop to re-torque is highly advisable in this scenario.
Q3 Can I reuse suspension bolts?
Can I reuse suspension bolts?
It's generally not recommended to reuse suspension bolts, especially torque-to-yield bolts (which are often used in suspension components). These bolts are designed to stretch slightly when torqued, and reusing them can compromise their integrity and clamping force. Reusing these bolts may lead to premature bolt failure or loosening. Always check the specific bolt type and the vehicle's service manual for recommendations. In most cases, it's best practice to replace the bolt with a new one.
Q4 How do I handle rusted or seized suspension bolts?
How do I handle rusted or seized suspension bolts?
Rusted or seized suspension bolts can be difficult to remove. Before attempting removal, apply a penetrating lubricant and allow it to soak for some time, sometimes overnight. Gentle tapping or heat may also be helpful. Avoid excessive force, which could break the bolt or damage surrounding components. If the bolt is severely seized, consider seeking help from a professional mechanic to avoid damaging the suspension. Never attempt to re-use a corroded bolt even if you do manage to remove it.
Q5 What is 'torque-to-yield' (TTY) and how does it affect suspension work?
What is 'torque-to-yield' (TTY) and how does it affect suspension work?
Torque-to-yield (TTY) bolts are designed to stretch a specific amount when tightened. This stretching provides the desired clamping force. These bolts should NEVER be reused, as they lose their elasticity. When replacing a TTY bolt, the torque specification often includes an angle tightening procedure (e.g., torque to 50 ft-lbs and then turn 90 degrees). It is essential to consult your vehicle's service manual for the proper procedure, using a torque wrench and angle protractor as necessary. Do not attempt to use these parts without following the procedure, as this may result in a catastrophic failure of the component.
