OK, I thought gimbal was just a term for the type of mount and they could be knife edge ball etc.
Just took this from Google
Basically tonearm pivots are either gimbaled, knife-edge or unipivot. Gimbalpivot. Gimbaled designs are the most common. With gimbaled arms the vertical and horizontal pivots use a needle point in contact with bearings, which allows the arm to move freely at the axis points .
On the Helius,it has 4 threaded cups and each one holds the 3 ball bearings.You can adjust each one with a slotted screwdriver
Hopefully the bloke j7 put you onto can sort it cheapish.
His minimum charge is £180.
Ouch
Can you not return it?
Well the problem is I collected it from Swansea which is a 6 hour round trip, he showed it working he asked if I wanted to remove the arm (I have the packaging) and I declined. Basically I think it’s my fault.
Did you take the counterweight off & secure the arm before moving it all?
I secured the arm but didn’t remove the counterweight, I realise that I should know better 
It’s no guarantee but removing the weight does reduce the likelihood of a nasty jolt damaging the bearings.
