Frequently Asked Questions

Find answers to common questions about torque specifications

Q1

Why are proper torque specifications important for body bolts?

Proper torque ensures the body panels and components are securely attached to the frame or body structure. Under-torquing can lead to loosening, rattling, and premature wear. Over-torquing can damage the bolt, the threads in the body, or even distort the panel, leading to alignment issues or potential structural weakness. For example, a bumper improperly torqued might detach in a minor collision.

Q2

What tool is best to use for torquing body bolts?

A calibrated torque wrench is essential for achieving the correct torque. While a regular wrench can tighten a bolt, it cannot accurately measure the force applied. Using a torque wrench ensures the bolts are tightened to the manufacturer's specifications, preventing both over-tightening and under-tightening. Remember to use the correct sized socket for the bolt to ensure a proper fit.

Q3

Can I reuse body bolts? What about locknuts?

It's generally recommended to replace any torque-to-yield bolts. However, many body bolts are standard and can be reused if they're in good condition with undamaged threads. Locknuts, particularly nylon lock nuts, should always be replaced as their locking function degrades with use. For example, a single-use torque-to-yield bumper bolt should never be reused because it's been stretched during the initial tightening and will not provide consistent clamping force upon re-use.

Q4

How often should I check the torque on body bolts?

While not part of routine maintenance, it's good practice to check body bolt torque after a major repair or collision, or when you notice a rattling noise. These are signs that bolts might need re-tightening. If you have been disassembling components that contain a large number of bolts, it may also be wise to re-torque these after some driving to make sure everything has settled correctly.
