Shimming CVD Axles - does anyone bother?

I have a RS4 3 Type SS with MIP CVDs. I just picked-up a set of clamping style hex adaptors for wheel mounting. When these are installed with the wheels, I see about .020 in-out play in the axles (when I push/pull on the wheel). Is there any reason that I should shim the axles to reduce this play to improve handling?

The dogbones are well into the transmission output shafts, so I'm not really worried about one of them coming out. The hex hubs do not touch the outer bearings, there is a paper thin gap when I push in on the wheel hub.

If shimming is recommended, would you shim the axle on the inside of the hub bearings (CVD side), or on the outside (axle-pin side) to remove the slop?

Am I just being way too critical here?

TIA,

Dan
 
I think that if you were to life the arm up (compressing the shock) and check for play, you should see there be virtually none.

Check it out and let me know.

Otherwise, you can drop an extra O ring inside the outdrive coming off of the diff (where the dogbone sits inside of) to absord the .020.

I really dont see much of a need to shim it, especially at .020, but, if you are dropping dogbones while running, then yes.
 
Excellent point - I never thought about the changing geometry of the suspension and drivetrain under compression. A quick check shows that the slop doesn't change much under compression, so I'll try an o-ring in the transmission output shafts. Do you think silicone fuel line would suffice? I could cut it to more closely prescribed dimensions.
 
Sure. It may come apart quicker, but it should work.

The O rings I'm describing are orange in color and sometimes reddish brown. Associated sells a bunch in a pack. They have MANY uses and would be handy in the parts box over time. Ultimately, that would be my choice. They hold up VERY well.
 
I've seen 'em. In fact, my RS4 type ss kit used them in the front only. My buddie's new RS4 EVO kit has them front and rear. Last time my LHS was out and Tower was also out when I ordered.

Thanks for your help.
