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.

Q1 What is the recommended torque specification for the body bolts on a 1981-1993 Dodge RAM-3500?
What is the recommended torque specification for the body bolts on a 1981-1993 Dodge RAM-3500?
The recommended torque specification for the body bolts on a 1981-1993 Dodge RAM-3500 is typically between 50-70 ft-lbs. However, this can vary depending on the specific bolt location and whether the vehicle has been modified. Always refer to the manufacturer's service manual for precise values.
Q2 Can I reuse body bolts, or should they be replaced?
Can I reuse body bolts, or should they be replaced?
Body bolts can often be reused if they are in good condition and show no signs of wear, corrosion, or stretching. However, it is generally recommended to replace them if they are damaged or if the vehicle has been exposed to harsh conditions, such as salt or moisture, which can weaken the bolts over time.
Q3 What happens if I over-torque the body bolts?
What happens if I over-torque the body bolts?
Over-torquing body bolts can lead to stripped threads, cracked mounting points, or deformation of the body panels. This can compromise the structural integrity of the vehicle and lead to alignment issues or rattling noises. Always use a calibrated torque wrench to ensure proper tightening.
Q4 How often should I check the torque on body bolts?
How often should I check the torque on body bolts?
It is a good practice to check the torque on body bolts during routine maintenance, especially after off-roading, towing heavy loads, or if you notice unusual noises or vibrations. For most drivers, checking every 12,000-15,000 miles or annually is sufficient.
