5 lug axle swap
I'm sure this has already been discussed but I wasnt able to find the info I'm looking for. My question is has anybody tried swapping a axles with like a '73 or newer to keep the same rear end and make it a 5 lug? I have a rear end out of an '86 burb I'm thinking about using if possible. Thanks in advance.

We had a local machine shop do ours, converted one to 5 x 5 and one to 5 x 4.75" because we ran into a deal on some cragars.....they just weld up the old holes and redrill the new 5 lug pattern then install the appropriate new studs. One also has to turn the center of the axle shaft down to accommodate the later model rear drums. cost was about $100.00 for the machine work plus the studs and new rear drums. Kieth |

Re: 5 lug axle swap
I think the 73+ axles are longer

Re: 5 lug axle swap
I had mine re drilled on my pickup bed trailer like Keith said, I believe it was Peyton Performance that did mine in Waxahachie. Cost was about what Keith stated.

Re: 5 lug axle swap
They are longer and I think the 67-72 axles are longer also.......I have swapped some around off other 64-66 trucks but ran into the fact that trucks with leaf spring suspensions had longer axles also (64-66) ???not 100% sure about that but be sure and check before you trade or buy other axles.......Kieth

Re: 5 lug axle swap
Thanks for all the info. I'm going to check around to find a machine shop to redo my axles.

Re: 5 lug axle swap
In '71, when GM went to the 5x5 bolt pattern, the width of the rear ends increased by 1.5". This measurement stayed all the way until 1988, when they changed the body style.
Unfortunately. there are no direct-swap factory axles to convert a 6-lug to a 5-lug. You either have to fill/drill your 6-lug axles, or order a new set of 5-lug axles from Moser, Strange, Mark Williams, etc.

Re: 5 lug axle swap
Yep, I think nearly everybody hits that decision at some time during their build. That's exactly why I went a bought a new set of Strange axles when I narrowed my 12-bolt in the '64. Buy 'em once, never worry about 'em again.

Re: 5 lug axle swap
Well after everyone's input and a lot of thought, think I'm going to switch them out with new ones. Especially considering I'm putting a stout big block in it.
