Cant seem to find anything of value http://www.pirate4x4.com/forum/sear...arch.php?action=showresults&searchid=81006&sortby=lastpost&sortorder=descending

So I'll ask. I need to redrill my yota axle from 6 on 5.5 to 5 on 4.5 to make it work with my jeep rims. I know I will have to turn down the hub ridge but that is no big deal, I also know that the 4.5 pattern will be .5" inside and offset within the 5.5 pattern.

Any special tricks to doing this, or do i jsut line up the holes and go?

I have full access to a machine shop (i work there), but do the holds need to be tappered from the inside out or no? is hte lug itself the part that is tappered?

Any help would be great. I am piccking hte axle up this weekend, need to get the shaftsand perches ready next week and am peiceing it all together the following week.

I had mine rear shafts' bolt pattern changed by Dutchman, went from 5x4.5 to 6x5.5.:D
I can tell you what they told me, maybe it'll be of help...

My shafts are Currie HD shafts, therefore they couldn'tn plug weld the old holes. They cut the old lugs inside their holes, then redrilled for the new lugs. They did a kickass job, you can't hardly tell where the old lugs were.
I had a choice of splined or threaded lugs, I went with threaded; makes life easier if/when a lug breaks (says Dutchman; no cost diff, so I went with that).

HTH,

If you do this you will have to change to something else if you ever upgrade your front rear. But if you must, I just take mine to the local place and let them do it. Only cost $50 and they even do the rotors, or drums to, and put studs in them. I'm not sure about the latest toy rears, but my 86, and 87 have a very large center on the axle. Make sure your jeep wheels have a large enough hole in them to fit over the axle. The last jeep wheel I saw that used the 5 on 4.5 bolt pattern, would never fit over the toy axle.

Edit: I see that you can turn the center down. However you should take a good look at the other side to make sure you can cut that side down to. I have no idea what this will do to the strength of the axle.

? for ya. Is that toy axle with 4.56s in NJ? for $500. You do know that you can get a commanche 44 and put 4.56 in it for that much?

I can do all the work in the shop. It is a full flegde machine shop.

I just wanted to make sure i was doing it right.

Yes it is the toy with 4.56's How fo you figure i can get a com 44 for that? Gears cost $150 + install kit cost $75 + thats $225, plus $200 for gear install that is $425 where am igonna get a d44 for $75??? All the places that i have looked for 44's (xj scout ect) were from $200 - $500.


I dont follow you on the q about turning them down?

isn't the "1ton" 2wd toy a 8 in toy rear axle with 5 on 4.5 bolt pattern? Anyway yeah you just drill the holes, sometimes it is hard to fixture the axle shaft if you have a horizontal milling machine it is very easy, if not you have to hang the axle shaft off the edge of the mill table. the normal press in studs are knurled so the diameter of the holes has a pretty wide tolerance, usually you can pick a stud that will work with a standard reamer size that you have in your shop.

EMS - I thought thats what you ment but was not 100% sure.
I would set up my gears, but I have yet to do it and would want to play with a few first. Eventaully Ill do that

Thats what i firgured. Just drill then get some studs.
