P38A Rhythmic Thrumming at 50-60

Took herself out for some shopping to a nearby town some 4 miles away.
The road between the 2 towns is 3 and 4-lane with some unrestricted bits, but most of it is 50.
On the way home I noticed a rhythmic beat like a thrumming within the drive train.
All new (<3k miles tyres) and all seem ok. Noise changed depending on coasting or under-power.
Could this be the 20YO UJ's complaining that their grease has dried out (its only done 18k miles in total)?

I will try and get some grease for my gun tomorrow and give them a squirt I think.
