Redrilling 5 lug axle for 4 lug

Post #1 by 62Cometman » Fri Jul 21, 2017 12:25 pm

Hi all, i was looking at finally getting around to swapping the 7.25 rear in my comet with an 8inch ive had tucked away in the corner of my garage for the past 3 years however its vastly too wide and a 5 lug pattern now this wouldnt normally be an issue and i could do a swap on the front except I have quite literally just finished installing the scarebird 4 lug kit on the front of my car so now i am wanting to try and keep it all 4 lug to also save myself from having to buy new wheels. I have the lovely pleasure of working for speedway motors so parts are always at my finger tips to check fitment and what not, the wonderful folks at currie enterpries make 28 spline axle ment for small bearing 8" and 9" inch fords however these axles are drilled for the standard 5x4.5 ford bolt pattern but i have ascertained that if i use one of the exsisiting bolt holes i could redrill these axles to a four lug pattern and keep my 4 lug wheels and keep a very stealth look. My only hesitation is that redrilling the holes would put 2 of the other 3 in centers between the exsiting 5 lug pattern and the 4 would only be at most 1/4 inch from another exsisting hole.

My question is do you think that will still be strong enough, does anyone have experience with this kind of modification?

You could probably weld up any existing holes that are too close, but it says in the description that Curry can customize an axle any way you want so why not order it with the pattern you want?

I took my 5 lug rear axles and drums to a machine shop and had them drill them for 4 lug.
It's easy to redrill from 5 lug to 4 lug when it's the same bolt circle, 4.5".

I know I could custom order the axles from currie but I could buy and modify 2 axles cheaper than I could get them direct from currie. To me a little bit of extra effort on my part to save myself some money is well worth it

:hmmm: You can have them re drilled to match the fronts,BUT you will still have to narrow them and have them resplined.If that is possible,as some axels are smaller after the splines.That gets expensive real quick.It would be much less costly to narrow the housing and get Curry to make a custom set of axels.
Good luck.Have fun.Be safe.

I had this done to my front brakes.
I'll be putting V8 spindles and disc brakes onto my '65 Mustang. I also want to keep the 4 lugs "look" and had them drilled from five lug to four. Easy peasy !

You could hunt for the early 1970's Maverick / Comet 8 inch housing or just the pair of axel's they would be real close to the width you need and they have 4 lugs. Good luck :nod:
