There’s a range of sizes as you use them to set the end float of the CV joint.

End play should be between 0.08 to 0.25mm

Ohh this is a new learning experience for me. Sounds like a need to use a set of feelers or a dial gauge.

And they're only fitted at the front.

Which is how it is. Ok, I won’t be adding them to the back after all. Why the slack at the back? 1951 80" S1 2.0

Because it doesn't matter at all if there is float on the rear shafts since there is a linear spline at each end, They are fitted at the front because the centre of 'flex' of the front CV needs to aligned with the axis of the swivel pins, which occurs when the stub shaft is pulled fully into the hub. The shims are provided to take up manufacturing tolerances and small differences in position of the hub etc.
The shims were, as far as I know, not fitted on later vehicles and I think it highly improbably that LR sharpened up on tolerances, so I presume in the end they either decided it didn't really matter or decided that if the CVs wore at an accelerated rate it didn't matter, it would just result in a bit more dosh from the customer. |

Wow.... it's a strange world. I posted a thread about these shims only yesterday, after a search, but this didn't come up. I don't know how this thread passed me by.
Like familymad, this is relatively new to me. I'd puzzled over the lack of shims on the rear - and here's my answer! But wouldn't/doesn't float here cause issues with rear disc brakes? Too much float contributing to pads being pushed back, and a longer pedal? Caliper attachded to axle; hub 'floats' on axle; too much float = pads get pushed back = poor pedal? On the other hand I think I'm missing something, and that properly adjusted bearings will keep float here to an absolute minimum. Every day is a school day. I assume by "later vehicles" not having them, we're not talking about a 1994 Tdi...? On the front, I've sat back and visualised the plane/axis of the swivel pins, and the CV flex and I can see that. Then I thought - what if the shims weren't there? It seems to me that would see the CV joint either wearing/chafing on the inside of the hub; or by the action of the CV joint being pulled millimetrically back and forward, lead to wear on the diff end of the halfshaft?

It's not the hub that floats, it's the halfshaft.
Wear at the diff end isn't usually a problem since the lubrication is good. |
