Axle lengths

[JohnnyJ]

Hello,
      I am trying to find out if both passenger & drivers side axles in my differential are the same           length & interchangeable.
      I have a 1976 SWB van with a very heavy differential & the axles have 21 tooth spline.
      I have seen pictures of the differential on the forum & I think "Ben" has a picture of the axle.
      The ratio is 4.45:1.
      Also, what is the ratio of a highway diff, or is it variable?
      Any information would be greatly appreciated.

Most diffs have different lenghts about 100mm that is to have the driveshaft in the centre of the vehicle That 4.45:1 sounds like it might be a highway diff not sure I thought most beddie diffs were in the 5s I think a good diff ratio would be about 3.08 :1 That's what I run & it's great for highway crusing Most Holden & Ford run 3.08 diffs so are easy to get Where are you at because I have a 76 diff that I took out of mine that you are welcome too if you can pick it up cheers Reid

  Thanks for the offer & the info Resteroid, but you too far away for me to pickup.
  I am trying to have a pair of axles made new, as over the years I have broken several axles & replaced several expensive rear bearings, & I can only replace them with axles 30 odd years old,so I thought new axles would alleviate the problem,but I am having trouble getting the passenger side axle out to measure the length. Has anyone got a passenger side axle (21 tooth spline, 35mm bearing journal, 6 hole backing plate) laying around they could measure for me?
  I considered putting a different diff in but it appears to me that it is very labour intensive & I am not too mechanically minded, unless there is one that is relatively "easy" to fit.

Hi,
   Ben was unable to get the measurements (thanks anyway Ben). Does anybody else know how long the passenger side axle is?

I take it, it is off the 10' drum ( to have the 6 hole), have 2 sitting in the back of the van, don't know what is the left and right, but can measure both and post in the morning.

Thanks Vandee, the length of both sides would be great.
