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 What are the torque specifications for my 2021-Present Hyundai Elantra suspension bolts?
What are the torque specifications for my 2021-Present Hyundai Elantra suspension bolts?
Unfortunately, a single, universally applicable torque specification does not exist for all 2021-Present Hyundai Elantra suspension bolts. Torque specifications vary based on the specific bolt location (e.g., control arm, strut, sway bar), the type of bolt (e.g., grade 8 fastener), and the vehicle's specific trim level. Refer to your vehicle's owner's manual or a reputable online service manual for your specific vehicle year and model to determine the correct torque specifications. Failure to use the correct torque value can lead to premature failure of the suspension components or unintended damage to the vehicle.
Q2 Why is precise torque important when tightening suspension bolts?
Why is precise torque important when tightening suspension bolts?
Proper torque ensures the suspension components are fastened securely without over-tightening. Over-tightening can damage threads, distort components, or lead to premature failure. Under-tightening can lead to the bolts loosening, causing the suspension to malfunction during operation, potentially leading to an accident. This is crucial for maintaining the structural integrity and proper alignment of the vehicle.
Q3 How often should I check and re-torque suspension bolts?
How often should I check and re-torque suspension bolts?
Suspension bolts should be checked and re-torqued during scheduled maintenance intervals. Regular inspection is recommended, especially after significant impacts or driving conditions like off-roading or extreme driving conditions. Consult your vehicle's maintenance schedule for specific intervals. In extreme cases, like after a collision or suspension repair, re-torquing should be performed by a qualified mechanic.
Q4 What should I do if I suspect a suspension bolt has loosened?
What should I do if I suspect a suspension bolt has loosened?
If you suspect a suspension bolt has loosened, do not drive the vehicle. Immediately seek professional assistance from a qualified mechanic for inspection and repair. Driving on a loose suspension bolt can lead to serious safety issues and potential vehicle damage.
