Did you twist one or snap one? Front or rear?

Best I have managed was a 24-spline non genuine rear - and countless 10-spliners.

1 rear twisted early EN26, 2 110 CV's never a stock early RR:eek: one that's with KAM 4.1's

COuntless front and rear 10 spline axles and centres:D

Tyres keep changing.. principally 235/85/16s Goodyear Armours for touring holidays, & 315/75/16s Claws for weekend play stuff. Around town or open road blacktop I run ProComp All Terrains in the same 315/75/16.

Did have 35" Simexes as the weekend tyre.

Gearing.. 4.11 CW&Ps & D2 1.2Qs in the t/case, so they offset, but oh so much quieter on the highway. Lo range has the 49% MD gears, so coupled with the 4.11s that gives me about 78:1 in lo/lo from memory.

Geez, the way he talked on LR 4x4 it sounded like he was using Maxi's :rolleyes:

EN 26 has a little more carbon than EN25. This gives is a little higher tensile and yield strength, but is not as tough (izod impact energy is lower).

The discussion on yield strength in some posts above could be missleading.

When a sample piece of mild steel is stretched in a tensile testing machine, it reaches a stage where elongation continues with no increase in tension (tensile load actually decreases). This is called yield, and the stress (load divided by cross section area) at yield is called the yield strength.

Alloy steels don't have a yield point as such, but at about 2% elongation the rate of elongation increases. So 2% elongation (often called 2% offset) is taken to be a yeild point for engineering purposes.

The real benefit from waisting axles is that it increases the strain energy that the axle can absorb before failure. The energy from shock loads is converted to strain energy in the axle. For our use, shock loads and the cumulative damage from shock loads is usually what causes a 4x4 axle to fail. This is why it is more frequent to break short side axles (their strain energy capacity is less because of their lower volume).

Thanks for clearing up my Gibberish... :D

Cheers John,
I was trying to find the corresponding terms to see how tensiled/shear strenghts are correlated in order to get an idea of different axles properties given the alloy used...

I hope it makes sense :D

Many, mechanical properties of steels are derived from the tensile properties determined by testing standard specimens in a tensile testing machine. It is not usual to test shear properties.

Torsion, as in an axle, creates shear stress in the axle (varying from zero at the centre to maximum at the surface.

Tensile loads in 1, 2 or 3 dimensions also create shear stresses and failure theories such as MSS (maximum shear stress) or Von Mises is used for 2 and 3 dimensional loads. Interestingly lead, which is normally very ductile will fail with a brittle fracture under 3 dimensional stress
