Ford Lug Nut Tightening Sequence Diagram - 5, 8 & 10 Lug Wheels (1978 Bronco)
Diagram showing the numbered lug nut tightening sequence for 5-lug, 8-lug and 10-lug F-Super Duty P40/P45 wheels.
This document is a wheel lug nut tightening sequence diagram from a Ford service reference. It shows three circular wheel hub illustrations, each depicting the lug stud positions with numbered tightening order. The first diagram covers a 5-lug wheel, showing the star-pattern order in which the five lug nuts should be tightened (1, 3, 4, 5, 2 around the hub). The second diagram covers an 8-lug wheel, common on heavier-duty trucks, with its cross-pattern tightening order numbered 1 through 8. The third diagram shows a 10-lug wheel specifically labeled for the F-Super Duty P40/P45 chassis, with its ten lug positions numbered 1 through 10 in the proper crisscross sequence. The central instruction reads 'TIGHTEN LUG NUTS IN THIS SEQUENCE.' A reader can learn the correct alternating (star/cross) pattern for torquing lug nuts on 5-, 8-, and 10-lug Ford wheels, which helps seat the wheel evenly against the hub and prevents brake rotor or drum distortion. No torque values, part numbers, or model years are given in the document itself; it is purely a graphical sequence reference. It was uploaded to a 1978 Ford Bronco gallery as part of a larger set of service diagrams.

Frequently asked questions
- What is the correct lug nut tightening sequence for a 5-lug Ford wheel?
- Per the diagram, tighten the five lug nuts in a star pattern following the numbered order shown: positions 1, 2, 3, 4, 5 arranged in a crisscross sequence around the hub rather than in a circle.
- Does this diagram cover 8-lug wheels?
- Yes. The 8-lug wheel diagram shows the eight lug positions numbered 1 through 8 in an alternating cross pattern to be followed when tightening the lug nuts.
- Which vehicles does the 10-lug wheel pattern apply to?
- The 10-lug wheel diagram is labeled 'F-SUPER DUTY (P40/P45)', indicating it applies to Ford F-Super Duty P40/P45 chassis with 10-lug wheels.
- Does the document specify lug nut torque values?
- No. The document only shows the tightening sequence patterns ('TIGHTEN LUG NUTS IN THIS SEQUENCE'); no torque specifications are given.
