I currently have one inner and outer cv boot linking on the same axle(or driveshaft - not sure what the correct terms is). Mechanic looked and it and told me it hasn't progressed too far to damage the joint and so all I needed to do was change the cv boots.
I forgot to mention to him that I also have a rolling ball sound(like marble rolling in a box) under the car which comes over uneven roads and maybe when taking turns. Having googled it, seems some suggest this rolling ball sound is commonly due to a damaged cv joint. If so this would mean there's no point repairing the boots as I'll have to change the joints so in order to avoid two consecutive repairs I may as well repair the whole axle anyway.
Can the described noise come when the cv boots are leaking or does it only come when the joints have become faulty and will need replacing? If the visual inspection suggest the boots only need replacing should I do that only as the mechanic advised, or since the sound is there should I change the whole axle instead? It could also be that the the ball sound is due a third issue but the inspection only reveals an inner and outer leaking cv boot at the moment.
