CV Joint/Boot or wheel bearing?

[sargey]

Ok, going down the motorway or over 65, the steering wheel has speed wobble (its not traction or tyres or balancing, had them all done)
also when breaking at that speed(hard ish), the steering wheel wobbles

could this be a wheel bearing problem or cv joint/boot problem or something else maybe?

Thanks

warped brake discs m8 by the sounds of it

Could also be a bent wheel - not that i have any experience of that

As above, check to see how many weights there are on the alloys to balance it. If its anywhere near 100g then points toward bent wheel. Most likely to be warped discs as above

It would be unusual for warped discs to cause wheel wobble when not braking

Could be brake discs warped if you're sure it's not wheel balance.

definately not the balancin as i got it done the day before i went on a long journey up the motorway and it was still happenin
warped discs surely would give bad braking? i had to break hard the other night and the braking was fine

try swapping front and rear wheels.
i had a wobble issue for ages, wheels were re-balanced twice, tyres changed, lots of checks done and still had it.
Swapping of wheels solved it.
