Hi

God, there's always something isn't there!

This has been getting louder for the last 500 miles, though still not really loud.

Is apparent at 50 + mph, at steady speeds, not when accelerating or de accelerating, even slightly.

Any ideas great please.

Thanks, Dave

There are numerous possible sources of humming noises. Wheel bearings are one, the diff is another. Something rubbing on the exhaust can make a very loud hum / whistle. If it's a steady, fairly quiet hum then it's likely something minor. If it's more of a throbbing, grinding hum then it probably wants fixing. I had that on a Mk1 Vitesse when the wheel bearing failed, and it was obvious from a brief inspection because the brake backplate was no longer parallel to the drum!

If it's load dependent (you say it's only at steady speed?) then I'm leaning away from severe bearing failure. Diffs definitely can behave that way and it's often not a problem, but check your oil level.

Thanks for that

Will have rear end up soon reg a brake issue.

Are rear wheel bearings more difficult to access while on car, due to prop/diff drag (fronts have always been obvious to me, as a notchy feeling when easily spun).

Cheers, Dave

at a steady speed have a think about tyre noise.   does it change if you  try adding  or removing  a good few PSI
