6 lug to 5 lug rear
Hi everyone I have a 86 c10 and i have a 86 12 bolt posi laying around but it has the 6 lug bolt patter. I have a 10 bolt non-posi under the truck right now, what is involved on maiking the rear end a 5 lug? Can I just swap the axles out? Or is it more complicated than that? Thanks!

Re: 6 lug to 5 lug rear
if you can find a 5 lug 12 bolt at the junk yard the axle will bolt right in where the 6 lugs are. you will nead the drums for the 5 lug brakes and make sure the drum diamiter is the same

Re: 6 lug to 5 lug rear
As far as I know, you can swap the axels. 12 bolts were available to 82.

Re: 6 lug to 5 lug rear
Ok, here's what I've heard. Swapping 5 lug axles into a 6 lug axle won't work, I think because of the length of the axle, but this is messing with a 60-72 12 bolt. The 73+ may be different. However I've been told that you can swap the carriers around.
Now, what I would do is grab a complete 5 lug axle and figure out which parts to mix and match.

Re: 6 lug to 5 lug rear
Any 8.5" 10 bolt or 12 bolt have interchangeble axels. Including the back plates for the brakes. The pinion and ring won't interchange. Same for a posi or gov-lock.

Re: 6 lug to 5 lug rear
The axel shaft interchangebility is for any 10 or 12 bolt after '70. Older models won't interchange like sailed2japan states.

Re: 6 lug to 5 lug rear
Is it possible to just change the front brake rotors to six lug using the existing brake caliper?
I see sets of OEM six lug 16" GM alum wheels on CL going cheap.

Re: 6 lug to 5 lug rear
I was reading on the 67-72 board that someone makes a specialty rotor that works with the hevy duty 1/2 brakes to convert to 6 lug. It only works if you have the 1.25" rotors, though.
