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 important for suspension bolts?
Why are torque specifications important for suspension bolts?
Incorrect torque can lead to premature failure of the suspension components. Too little torque means the bolts might loosen, potentially causing a loss of control during driving. Too much torque can strip the threads on the bolts or damage the surrounding metal, leading to a catastrophic failure. Proper torque ensures the bolts maintain the correct tension and alignment, crucial for vehicle stability and handling.
Q2 What if I don't have the correct torque wrench?
What if I don't have the correct torque wrench?
Using an inaccurate tool can lead to incorrect torque settings, potentially compromising the suspension's integrity. If you do not have a torque wrench capable of measuring the specified torque values, consult a qualified mechanic for proper installation or repair.
Q3 How often should I check the torque on my suspension bolts?
How often should I check the torque on my suspension bolts?
Regular inspections are recommended. While specific intervals depend on driving conditions and mileage, it is wise to check the torque on suspension bolts during routine maintenance, such as after major repairs or when experiencing unusual handling issues (pulling to one side, vibrations). A professional inspection is advisable every 25,000-50,000 miles or as recommended by your vehicle's maintenance schedule.
Q4 What happens if a suspension bolt breaks?
What happens if a suspension bolt breaks?
A broken suspension bolt can lead to significant handling problems, potentially causing a loss of control. This can be especially dangerous at high speeds or during turns. Immediate attention from a qualified mechanic is necessary to replace the broken bolt and ensure proper functionality of the suspension system.
