Axles
Know this is an old subject, but im having my 69 12 bolt rearend worked on. The problem is both axles from Summit seem to be the same size, no right or left thus my drum overhangs on the right(passenger side) backing plate. Thought it was because I changed carriers. Has anyone else had this problem while doing a 5 lug conversion?

Re: Axles
All I can tell you is that the axles are supposed to be the same length.

Re: Axles
Axles should be same length, only thing it could be then is mis-matched brake drums. Are the drums exactly the same ?

Re: Axles
Are your backing plates the same? I know for sure that 4x4 backing plates are different than 2wd backing plates. When i swapped a 2wd rear into my 4x4 i had to swap the backing plates along with the axles. My 4x4 ones had 2 1/2" brakes and the 2wd one had 2" brakes, thus making the difference. You may check your brake drums also. Make sure they are the same. Other than that, your axles should be the same size along with the tube length of your housing.

Re: Axles
My rearend is the same one that came with the truck. Due to the bolt breaking that holds the pin in where the axles meet. I had to change carriers and ring gears due to me destroying my old carrier.

See I was told that one side was supposed to be longer then the other. Also my left (driverside) axle has at least 2 inches of space between the axle backing plate and the rear wheel cylinder while the right axle backing plate sits on the wheel cylinder. |

Re: Axles
Measure your axle tubes and make sure they are the same length. Measure your old axles too. Just make sure everything is the same. That'll give you a reference as to where to start.

Re: Axles
Double check & make sure the axles seated completely into the carrier for the c-clips. When I got my first axles from Moser, the splines were not cut @ the same degree as the factory axles & they would not slide all the way in place.
I took several tries getting it right.

Like mentioned, the axles (L & R) should be the same length. How do they compare vs. your original axles? Same length?

Yes both axles match my old ones. Im still betting its the carrier. I know all carriers are not alike due to casting. This one came out of a 6cyl 67-70 truck because of the gears (either 3:55 or 3:73's). The 6cyl carrier and my old one have the same numbers on them. My axle tube on the right side appears to be shorter then the left. But if it is, then how could I have the same size axles? |

Re: Axles
Regarding your most recent question, personally I'd sand/media blast it, then prime and paint it. If you do sandblast, make sure you cover/tape up everything. That sand and dust gets into absolutely everything.
Regarding a posi 12 bolt, I think $350 is in the ball park "IF": It's the right gear ratio you need, The posi clutches aren't all worn out All bearings are in decent shape Shows a good wear pattern indicating the setup is correct. It's an exact bolt-in and you don't have to do any other mods to get it to fit It solves the original problem of off-centered tires and drums Otherwise, I'd think it's worth a lot less depending on its condition. Good luck.

Re: Axles
I found another one for $150. This one was converted to leaf spring for a 56 truck. How hard would it be to turn it back to coil springs? Also its a posi with 3:55's in it.

Re: Axles
Ok this rearend is out of a 72 C-10. I was told that it would not fit under my 69. Also my new axles will not fit because they're too short. Help!!!!!!

Re: Axles
It was converted from coil to leaf spring to fit a 56 truck and it has 6 lugs. Is there anyway to tell what year it is just in case the guy has the wrong infomation?
