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 between components. Overtightening can stretch or break bolts, damage threads, and potentially cause premature failure or binding. Undertightening can lead to loose components, excessive play, and dangerous handling issues. For example, a loose lower control arm bolt could cause severe instability and loss of control while driving.
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 the preferred method, it is not recommended to perform critical suspension work without one. If you absolutely must, make sure bolts are snug with a standard wrench and bring the car to a professional mechanic as soon as possible to have the torques verified and tightened. Failure to do so could be extremely dangerous. 'Snug' means hand tight with a reasonable amount of force. Do not over tighten without a torque wrench.
Q3 Do I need to replace suspension bolts after loosening them?
Do I need to replace suspension bolts after loosening them?
It's generally recommended to replace 'torque-to-yield' bolts, but for most suspension bolts on the 1996-1998 Acura TL, it's acceptable to reuse them if they are in good condition and haven't been excessively stressed. Visually inspect bolts for any signs of stretching, necking down, damage or corrosion and replace if any of these are present. If in doubt, always replace the bolt. Especially replace the bolts if previously torqued incorrectly. Use new nuts where applicable for proper clamping.
Q4 Should I use anti-seize or threadlocker on suspension bolts?
Should I use anti-seize or threadlocker on suspension bolts?
Generally, a small amount of anti-seize compound on the threads of suspension bolts is acceptable, especially in areas prone to corrosion. However, avoid using threadlocker unless explicitly specified by the manufacturer. If you have a question regarding using a particular compound, consult a professional mechanic. For example, using threadlocker on a bolt that requires a specific torque spec could throw off the tightening process.
Q5 How often should I check the torque on my suspension bolts?
How often should I check the torque on my suspension bolts?
It's a good practice to check suspension bolt torque after any major suspension work, such as replacing components or doing repairs. It is also recommended that they be checked after approximately 1000 miles after the repairs. During regular maintenance, a quick visual inspection of the suspension components should be performed which can highlight any potential problems. A full torque check should be done every 2 years or after driving in harsh conditions or hitting a large bump, which may stress the suspension system.
