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 on suspension bolts?
Why is it important to use the correct torque specifications on suspension bolts?
Using the correct torque specifications is critical for suspension safety and performance. Over-tightening can damage bolts, threads, and suspension components, potentially leading to failure. Under-tightening can cause components to loosen, resulting in instability, premature wear, and a loss of control of the vehicle. Correct torque ensures proper clamping force for secure and safe operation.
Q2 What happens if I don't have a torque wrench?
What happens if I don't have a torque wrench?
While it’s strongly recommended to use a torque wrench, if you absolutely must proceed without one, you should seek help from a professional. Guessing or relying on 'feel' is extremely risky. You risk either over or under-tightening bolts, with serious safety implications. If you continue to proceed without the proper equipment, tighten the bolt by hand until snug then turn the bolt another 1/8 to 1/4 turn. If you do this, you *must* get the bolts torqued properly by a professional as soon as possible.
Q3 How often should I check the torque on my suspension bolts?
How often should I check the torque on my suspension bolts?
Generally, it's good practice to check suspension bolt torques after any suspension work is performed, including replacing parts or after any major impact event (e.g., hitting a large pothole). You should also check the torque on suspension bolts after the first 50-100 miles after suspension work has been completed. In most scenarios, annual checks are sufficient for normal driving conditions. If you frequently drive in harsh conditions, check your bolts every 6 months.
Q4 Can I reuse suspension bolts?
Can I reuse suspension bolts?
Generally, it's recommended to replace bolts that are considered 'torque-to-yield' or stretch bolts. These bolts are designed to stretch upon tightening, and re-using them can lead to weakened clamping force. When in doubt, always consult the service manual or consider replacing bolts.
Q5 Where can I find the specific torque specifications for my 2020+ Chrysler Voyager suspension?
Where can I find the specific torque specifications for my 2020+ Chrysler Voyager suspension?
Always refer to the official Chrysler service manual for your specific model year. This information can usually be found online through subscription services, local libraries or repair shops. Additionally, some reputable aftermarket repair data providers may have this information. Be certain you are working with the correct specification for the component and year of your vehicle.
