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?
Proper torque is crucial for maintaining suspension integrity and safety. Under-torqued bolts can loosen, leading to instability, component failure, and potential accidents. Over-torquing can stretch or break bolts, damage components, or cause preload issues, also compromising safety and performance. Correct torque ensures proper clamping force and load distribution.
Q2 What happens if I over-torque a suspension bolt?
What happens if I over-torque a suspension bolt?
Over-torquing can permanently damage bolts by stretching or weakening them, potentially leading to failure. This can also deform the mating surfaces or stress suspension components. For example, an over-torqued control arm bolt can cause binding, restrict suspension movement, and affect handling. Always use a calibrated torque wrench.
Q3 Can I reuse suspension bolts on my Prowler?
Can I reuse suspension bolts on my Prowler?
It is generally recommended to replace certain types of suspension bolts, especially those that are torque-to-yield (TTY) or designed for single use. These bolts are designed to stretch upon tightening, providing the correct clamping force. Reusing them can lead to improper torque and reduced clamping force, increasing the risk of loosening. Check the service manual for specific bolt replacement guidelines.
Q4 How often should I check the torque on my Prowler's suspension bolts?
How often should I check the torque on my Prowler's suspension bolts?
It's recommended to check the torque on suspension bolts after performing any suspension work or after the first 50-100 miles following any suspension service, as they may settle. A yearly check, or after major impacts like hitting potholes, is a good preventative measure. However, if you notice unusual noises or handling issues, check them more frequently.
Q5 What tools do I need for tightening suspension bolts?
What tools do I need for tightening suspension bolts?
You will need a torque wrench with appropriate range, correct size sockets, and possibly extension bars or adapters. Ensure your torque wrench is calibrated and accurate. A service manual containing torque specifications is also essential. Using an impact wrench is NOT recommended for final tightening of suspension bolts as it is impossible to accurately control the torque using this type of tool.
