Outer Limits 4x4 Board

Stuck my head under a D2 the other day and noticed a proper CV joint with a boot, and everything.

Bit different to my D1 and earlier Rangies.

Anyone know if the later set up is better?

Why are any of the other CV joints not "proper" . Only difference is the CV joint is exposed - which is really a bad thing because it is grease lubricated not oil (which is better), and it is easy to damage the boot and lose the grease.

AFAIK the D2 CV is no stronger than the usual defender/rr CV (definitely weaker than the strongest factory CV - the 110 AEU2522).

There are pics on here somewhere of slunnies Maxi-Drive front shafts and CV's for his D2. I think mal fits a ring to the CV to add some strength.

By 'proper' I mean the same as cars and exposed, as opposed to the older style (and what I was more familiar with, except for Jeeps that use an exposed uni instead) which are covered under the CV joint/swivel bearing housing.

Didn't mean they were made of alien intestines!

You actually answered my question after the went in, so thanks!


Now I think of it, the manufacturing process would be a whole lot cheaper using a sealed CV joint and not bothering with the housing and seal assembly. This should be both from a materials and definitely from a labour/assembly line perspective. I guess this is why they changed.

So ISUZUROVER you are saying the oil covered CV's system is better. I am currently changing to this system. Could you tell me the reasons it is better some drawback that I can think of is if water gets in it contaminates everything including the diff.

Sorry for Hijack. Thanks from Shane

Oil is (almost always) a much better lubricant than grease - so an oil lubricated CV should last longer (long term wear not breakage) than a grease lubricated CV. Of course that is providing that you keep enough oil in the swivel and don't let oil in there.

If you want to be really serious you can fit separate breathers to each swivel. I check mine for water after each trip where I drive through deep water - as long as the wiper seals are good then the water usually stays out.

its probably fairly irrelevant if D2 cvs are better, because the work to fit D2 cvs to anything else is fairly huge - involves swapping complete diffs over, and rewelding brackets for radius arms, either on the chassis (to retain D2 radius arms, possibly a bit better due to the way they're hinged at chassis), or on the diff.

Overall, unless you had some specific reason to fit a D2 diff, be easier to spring for upgraded cvs.

I dont think the D2 CV is anything special though. The ones that Mal uses are a little bigger that standard and run a ring around the bell in them. He reckons they will snap the (alloy) axle before the CV, though at lock the bell may still break.
