Can anyone tell me please, the diameter of the drifts I need to remove the front and back bushes on wishbone? I have a decent press, just need the drifts.
Thanks in advance for any help.

You'll need a big press just to get the wishbone in for the front bush; they don't physically fit in my 10ton floor press.
This is how I do them; I can measure the drive tool if it would help:

The rears are simple, and an appropriately sized socket will do the job.

Removal is easy. Relatively...
Fronts: burn out the cores, then cut a slot in the casings with a hacksaw and drift the remains out with a cold chisel.
Rears are a bit more of a faf, think I used to use a suitable socket and a large G clamp.
Mercedes and BMW both use a dedicated tool...

I've yet to invest in the bush tool, but the ball joint one works a treat. There is a master set which would probably cover the Omega sizes.

That looks far too small for the Omega bushes, although the design is good.
Mine uses the tubes from a wheel bearing kit, but needs an adapter to fit on the wishbone.
The drive cups need to be relieved to accommodate the raised centre of the bushes.
Burning bushes out is frequently mentioned; I can still taste the one we tried, and that was in the last century. This sort of rubber is very hard to set alight.
Cutting out the old front bush requires few tools, and is OK if you're fitting polys. It doesn't help much if replacing them with stock. Although that is a very odd thing to do.
The rears are easy enough for anyone who has owned a press for more than a couple of jobs - everyone I've seen has a pile of improvised spacers and packers nearby.

If you dont want the stench of burning rubber, drill a lot of holes in the rubber part of the bush then whatever means of brute force and ignorance to knock the rubber part out.
Then hacksaw the outer metal ring until its almost cut through then knock it out with a small chisel.
As mentioned, always best to fit polybushes in the front, once the old bushes are out.

This ^^^^ for fronts,
Poly fronts, std rubber for rear.
I had the advantage of a 30tonne press, to push rears in,
If your doing rear suspension donuts I think there's a guide, they aren't to difficult with common hammers and pry bars to remove, and washing up liquid to replace

I use KY jelly, slips straight in :y

KY is good as it's water based, and oil or grease might allow it to continue moving once fitted.

Is it not oil based? Being a mix of mineral oil and wax. That it's called petroleum jelly should be a giveaway.
I give the rear donuts a squirt of silicone spray before tapping them in with a BFH, wind in the bolt as far as it will go then use the weight of the car to get them in the rest of the way.

KY is definitely water based. You are thinking of Vasoline, which is oil based.
Given the main use of KY, I'd prefer it wasn't a petrol based product.
