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.
Prevention:
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.
Prevention:
Follow the manufacturer's specified torque sequence pattern.
Dirty Threads
Dirt, rust, or old thread locker can affect torque readings and proper fastener tension.
Prevention:
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.
Prevention:
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.
Prevention:
Check if specs are for dry or lubricated threads. Use specified lubricant when required.

Q1 What are the recommended torque specs for lug nuts on the 2010-2018 Ram 3500?
Q1
What are the recommended torque specs for lug nuts on the 2010-2018 Ram 3500?
The recommended torque for lug nuts on a 2010-2018 Ram 3500 IS 140 ft-lbs. This value must be strictly adhered to to ensure proper wheel attachment and safety.
Q2 What IS the correct torque sequence for tightening cylinder head bolts on a 2014 Ram 3500 6.7L Cummins engine?
Q2
What IS the correct torque sequence for tightening cylinder head bolts on a 2014 Ram 3500 6.7L Cummins engine?
Follow this sequence: Tighten bolts to 50 ft-lbs. in the following order: 13, 7, 1, 9, 15, 3, 11, 5, 17, 2, 10, 6, 18, 4, 12, 8, 16, 14. Then, tighten bolts to 75 ft-lbs. in the same order. Finally, tighten bolts to 90 ft-lbs. in the same order.
Q3 How often should I check and tighten the torque on my Ram 3500's suspension components?
Q3
How often should I check and tighten the torque on my Ram 3500's suspension components?
Suspension components, including bolts, nuts, and linkages, should be inspected and torqued to specifications during every tire rotation or oil change, or at least every 5,000 miles.
Q4 What type of torque wrench should I use for critical components on my Ram 3500?
Q4
What type of torque wrench should I use for critical components on my Ram 3500?
For critical components, such as cylinder head bolts or suspension components, a high-quality, calibrated digital torque wrench that meets industry standards, such as ISO 6789, should be used.
Q5 Can I use a torque multiplier to increase the torque applied to a bolt beyond the capacity of my torque wrench?
Q5
Can I use a torque multiplier to increase the torque applied to a bolt beyond the capacity of my torque wrench?
Yes, torque multipliers can be used to increase torque output. However, they should be used with caution and in accordance with the manufacturer's instructions. Misuse can lead to over-torquing and component damage.
Q6 What precautions should I take when using power tools for tightening bolts?
Q6
What precautions should I take when using power tools for tightening bolts?
When using power tools, apply controlled force and avoid over-tightening. Always follow the manufacturer's recommended settings and tighten bolts gradually, checking the torque value regularly.
