4-Lug Inner Spindle Nut Socket

This 1/2-in drive socket removes spindle nuts on heavy-duty Ford and GM trucks. It fits Ford F250 and F350 models from 1985 onward with Dana 50 or 60 axles. Chevrolet and GMC 30 Series from 1987 and Dana-equipped front suspensions are also covered. The 2-1/2-in inner diameter matches the specified lug pattern.

Installation and Common Mistakes

Attach the socket to a standard 1/2-in ratchet or breaker bar for hand-turning only. The manufacturer highlights that this tool is not for impact wrench use; power tools can damage the socket or the spindle nut. Magnetic latches on the storage case keep the socket secure when not in use. Applying steady force prevents rounding the four lugs.

Compatibility Check Before Ordering

Verify your truck matches the listed applications: Ford F250/F350 1985 and newer with heavy-duty axles, or GM 30 Series 1987 with Dana 50 or 60 configurations. Confirm the spindle nut uses a 4-lug pattern with a 2-1/2-in inner diameter. Ensure you have a 1/2-in drive hand tool available, as impact use is prohibited.

Questions about this item

How can I confirm the 1/2-in drive spindle nut socket is seated correctly on a 2-1/2-in inner diameter nut?

The socket engages fully when all four lugs sit flush against the nut face and the 1/2-in drive square mates without wobble on your breaker bar or ratchet.

What does the purchase include and is an impact wrench required?

The box contains only the 4-lug inner spindle nut socket; an impact wrench is not required and the tool is marked not for impact wrench use.

Which vehicle applications match the 4-lug 2-1/2-in specification?

It fits Ford F250/350 heavy-duty axles 1985 and newer, late-model F350 with Dana 50 or 60 axle, 1987 Chevrolet/GMC 30 Series, and Dana 50 IFS or Dana 60 monobeam front suspensions.
