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 torque specifications so important when working on the suspension?
Why are torque specifications so important when working on the suspension?
Using the correct torque specifications ensures that suspension components are held together securely without being over-tightened, which can lead to bolt failure, component damage, and compromised handling. Under-torquing can cause components to loosen, leading to instability and potential accidents. Proper torque promotes consistent performance and safety.
Q2 What tools do I need to properly torque suspension bolts?
What tools do I need to properly torque suspension bolts?
You will need a torque wrench that can accurately measure the specified torque range for the suspension bolts on a 1993-1997 Chrysler Concorde. A selection of sockets, extensions, and possibly universal joints will also be necessary to reach the various bolts. A quality torque wrench that has been calibrated should always be used.
Q3 What happens if I overtighten a suspension bolt?
What happens if I overtighten a suspension bolt?
Overtightening can stretch or break the bolt, damage the threads in the component, or cause premature failure of the suspension part. It can also distort the component leading to incorrect alignment and handling issues. In severe cases, an overtightened bolt could shear off, requiring costly repairs and creating a dangerous situation.
Q4 Do I need to use threadlocker on suspension bolts?
Do I need to use threadlocker on suspension bolts?
Threadlocker (like Loctite) is often recommended on specific suspension bolts, especially those that could loosen due to vibration. Consult your service manual or specific torque specifications for your vehicle to determine which bolts require threadlocker. Generally, lower control arm bolts and steering components often require it.
Q5 Should I replace suspension bolts after removal?
Should I replace suspension bolts after removal?
It's generally good practice to replace bolts that have been exposed to high stress or torque, especially if they appear corroded or worn. Some bolts are designed as torque-to-yield, making them one-time-use. Refer to the service manual for specific recommendations, as some suspension bolts are designed to be reused multiple times, while others should always be replaced after loosening.
