Play in swivel?

Jacked up the wheel and I can move it side to side with the play
(as in the motion the wheel makes if the steering wheel is
moved). There is no up and down movement so isnt't the wheel
bearing. The movement also reduces slightly when the brakes are
applied.
To get rid of the play, do you just adjust the preload with the
shims and checking with the spring balance?
Its a new timken bearing I put in last year and im assuming its
just bed in now meaning the preload setting's too low

hi
if it is bearing and railco bush that are needing load
adjustment or road wheel bearings you should have movement along
the vertical axis (pushing the tire in from top and pulling it
out from bottom)
usually such movement (as if steering is applied) is associated
with ball joint wear.

But if it was ball joint, why would the play reduce when the
brakes are applied?

Movement that stops with hard application of the brakes is wheel
bearing Or worn stub axles allowing the bearing race to move on
the stub axle.
Push and pull the top of the tyre. If you have in and out of the
top of the tyre it is the top railco bush worn. heck with brakes
applied to stop bearing movement. Adjustment is useless it just
needs more power than your arm to move it but the car will
easily do it when driving.
Push and pull the front and rear of the tyre. (try and turn the
steering one way then the other) This checks steering ball
joints just the same as rocking the steering wheel under load.
A large bar under a jacked up tyre and use the lever to try and
lift the wheel. if you have up and down movement then your
railco bush can be adjusted to re set the pre load and thus
remove up and down movement. if this was set up properly they
never need adjusting so somethinghas worn or broken, often the
bottom bearing has collapsed.

Something wears in the swivel pin/Railko bush over time. I
rebuilt the swivels on FMW over 10 years ago and they've needed
shims removing a couple of times in that period. The first time
wasn't long after they were done so bedding in does occur. As
has been said if it's that you should have movement at the
top/botton of the tyre. Checking steering joint play is easiest
if you have an assistant rocking the steering back and forth
whilst you look at each joint.

There is a fibre shim thrust washer in the bottom of the top
railco bush and pin. Wear in this will allow the preload
adjustment to need adjustment. It should be said however that
with oil lubrication and properly fitted and set up in the first
place the railco bush complete should wear at the same rate as
the thrust washer. And seeing as adjusting the pre load does not
remove play in the sides of the railco bush it is hard to see
why shims would ever need adjustment unless fitting a new railco
bush complete.
On vehicles not fitted with a steering damper this railco bush,
thrust washer and correct preload, IS the damper and stops front
axle/steering tramp.

The swivels and things wont be worn, they were both completely
overhauled last year with OEM bits and have only done light
driving since

New bits or not. The only test it to get pushing, pulling,
levering and jacking. You will find it easier to have a mate
rock the steering and use the brakes whilst you are checking.
There is a reason your MOT examiner uses a helper! Telling your
MOT examiner it has had a new this or that, does not stop him
from checking it properly himself!!!

I know that :) i was merely saying to eliminate worn swivel
bushes and bearings out of the equation :)
Will stick the front on stands over the weekend

And I would suggest you take nothing for granted. If a railco
bush was not seated properly when it was installed then your
preload will be too light or you might even have some play in it
and need reshimming properly. Same goes for wheel bearings.
