Interesting - and worth checking for. 

I had the right-side axle rebuilt with new CV joints in December or so - it just wasn't practically doable for me to R&R them myself and get the quality of new joints that I wanted - and I suspected, when the first odd symptoms appeared, that it may be a result of something that was done incorrectly on that job. Like inadvertent damage to the wheel speed sensor - or, indeed, a slippin ring. Thanks for the suggestion.
