No worries - I figured that was the case, however thought the failure torque figures may be able to narrow it down to a few likely options.

So - we can all call our axles Aerospace then???

I have "AEROSPACE" (AMS-6418) axles front and rear!!!
Ashcroft make "AEROSPACE" (AMS 6414/6415) axles as well!!!
I also have some Longfield CVs made from "AEROSPACE" AMS6257!!!

Hmmmm, but I can't find the same for McNamara EN25 is listed as "aerospace" steel S97 - but I can't find an AMS number???

Still not sure which way to go with axles.Welded stripped flange to axle for time being. Other axle has abit of play at flange, suppose its on way out as well.

How long have you run em so far ?
And did you keep to the rangie hub seal or revert that to the standard defender item ??

Ben, the Aerospace material that kam uses could be something basic but heat treated to its highest UTS......performs well on a slow whind up torque test....but how will it handle the 1000's of cycles offroad???

only time will tell

Indeed.

They are the only axle manufacturer I am aware of who won't tell you what steel they use, so I looked elsewhere when buying axles recently.

A Q for the OP, could I hazard a guess and say that you weren't using an 'X' axle set ?

The 'X' axles used a longer spline snout on the drive flange and a corresponding longer splined axle compared to the stock length axle/flange assy and the 'standard' MDE 1724/1725 axles.

Can't recall how much longer they are and the catalogue I have doesn't say, but it's significant.

10mm longer I believe Rick My HI-Tough rear X ones are anyway

what did you weld them with? what was your welding procedure?
