Thread: Defender 110 front diff pinion angle

Hi Tony

Not looking for a rock crawler but it is (hopefully engineer dependent) going onto air suspension so, if I have to get all 3 shafts made, I want to do it correctly.

The front diff up pinion angle seemed unusual to me as I'm used to series that have parallel flanges everywhere and I wanted to check if the 17 degrees is a problem. But going by some replies it may be standard (have just been offered a DC shaft).

As an aside does anyone have a Defender extreme? I wonder if they could send me an image of the tyre placard? Just more evidence for the engineer.

another Q. Which Disco had the rubber donut and where? Just one of the shafts I've acquired during the build.

Not using the donut, but the cardan and shaft may be useful for modifying.

Both D1 and 2, diff end of the rear shaft.

I don't know either way for the later RRC

Took a 6x6 into melbourne driveshafts and the local hardies,

Both advise the same, dont run CV's for the propshafts, they will be at angle all the time, rotating at higher than their normal speed and will heat up, cooking the grease and causing premature failure of the CV.

According to the engineering dude who was on the call while I was at melbourne driveshafts, yes the CV's are stronger at straighter angles and lower speed but the amount of movement between the balls, race and outer shell at the angles they run on a 6x6 Ujs and DC joints are the way to go providing they are correctly greased. The only position worth considering a CV for is the one for the rear output on the back of the gearbox.

yes converting the rear carrier bearing to a greasable one is a good idea... So next service time.....

When you say CV's, do you mean CV or double cardan? I'm thinking you meant the double cardan?

As regards strength I have no idea, but even if they are weaker, there are obvious reasons that many vehicles have them, it might be a trade off I guess... Like everything in life!

Neither my 2 door or 4 door MY85 RRc had donuts

No, I mean a Constant Velocity joint, not a Double carden, those are just a glorified pair of UJS with a spigot alignment bearing assembly.

Yeah ok, what vehicles use a CV there?

Not really familiar with anything else much, maybe patrols and LandCruisers..a bit.

Or am I misunderstanding something?
