Are you talking about the large female hex on the axle? I jerry-rigged a tool on the spot with a large nut (SAE of all things, it may have been a 5/8", 15/16" wrench size, can't remember off hand, sorry). I sandwiched it on either a 3/8" or 1/2" bolt and nut and torqued it all together tight...too lazy to hook up the welder...and just use a wrench. It now stays in my toolbox as my special axle nut tool. I suppose in a pinch you could find a similar bolt, use the head as the insert and clamp some vice grips in the threads to leverage it.
If you have a "normal" spark plug socket tool (with a ¾" hexagon drive at its top), I read that you can use it backward to remove the front wheel. I mean insert your ratchet extension from the inside on the socket and insert the ¾" drive into the wheel retaining bolt. Let us know if it works; I never tried it as mine is a C model and this is supposed to work only on D model...
If your front axle is 17, 19, 22, or 24mm a Motion Pro T6 axle tool is great to have.... I've seen them for 30 bux and makes the job easy. Maybe try calling some local shops cux it's not an uncommon tool, or just google til you find it for $29.99.
Thanks guys for info...Claude I tryed that plug socket..it goes in ok but you cant get the extension in thru the other way because my socket goes from round to the 3/8" size if you know what i mean..Gonna give it a go with flymyways idea with the bolts and stuff if I can find em around here if i cant just gonna go buy the right tools..lol
I found a set of hex head/ allen head type sockets at AutoZone. They were sold as tools for metric trannys in Euro trash cars. It came in a 3 pack and one of them was the right size for my '90 ZX11 front axle. I don't remember the cost but it was cheap enough. Might check that out.
