Front bearing

[steve_000]

Right quick one, when i get to 40 there is a rumble from the front passenger side, then it goes at 45, then appears again about 75.

I have history to say the bearing has been replaced 2 years ago, possible for it to be the suspect?

Also a whine from the rear, more a mechanical noise, like, metal slightly touching metal to create a grinding noise. Nothing serious though, only happens on movement and gets slightly faster as car get faster.

Is that the diff?

Cheers for the help!
