Since a lot of the 50th Annv. cars are being released and a question was brought up about redline Wheels I thought I’d show off the evaluations of the basic hot wheels axels

The Redline era axels

USA made car with 4 separate axels for each wheel in an odd straight Z pattern crimped into place.
Hong Kong made car 1 axel for each set of wheels in a U shape and clipped in with a bracket.
Late redline era capped wheel axel. Straight axel as puke be seen on all future Hot Wheels cars but held into place with a plastic strip to still give it that shock suspension was found on late USA casting and conmen for Hong Hong castings.

Late redline/early Black walls plastic/metal base

The straight held in place by a J hook where the wheel was popped into place. These hooks will break from over time due to play wear and plastic breaking down. I’m oddly this J hook can also be found on some metal base cars but not often since it was more difficult to get the axels in place with out them getting bent.

The crimped style with 2 long prongs to hold the axels in place from the 80’s well into the 90’s and some 2000’s cars that still used old toolings. This design style is still used today but with slightly changes to use less metal.

The modern era that is currently being used

The 3 prong crimp design used in almost every basic casting with both metal and plastic bases excluding some lifted vehicles that use the interior to help hold the wheels once the space is too narrow to crimp the wheels in place.

Thanks for looking. This isn’t every example of how the axels are held in place there where casting that had crimps that were more closer to the wheels to help hold them in place or just used part of the interior (like the off road trucks). This just a basic over view of them for the basic line not digging into the higher end like NEO Classics that use a mix of USA and Hong Kong early redline axels.
