Sierra wheel bearing play normal?
Quick question - If I pull hard outwards on my rear wheels I can feel a certain amount of play ..... is this normal? It seems the same both sides
which makes me think it is.
Sierra abs hubs btw

The thing is I can only feel the play with the weight of the car on the wheels. No detectable play if I take the wheel off.
Maybe I should check the tightness of the bloomin great hub nut - what torque should it be set to?

You shouldn't feel any freeplay in the rear wheels
The torque required is very high, I think 250 ft/lb ( someone will tell you if i'm wrong).

I went with put the breaker bar on and jump up and down on it till it was tight enough

Ahhhh you must mean 'FT' 
200-220ft/lb sounds about right after doing a search.
So are these bearings preloaded in some way? it is just strange that I can only get them to wobble with a real hard yank

Are you sure it's the wheel bearings and not the top hub carrier or camber adjuster loose?

I thought it was more like 350Nm from memory...

250-290nm or 185-214 lbf ft says Mr Haynes

Think I'd be checking the hub carrier bushes.

as above, the sierra bearings are preloaded by the tolerance stack up at manufacture, the huge torque is nowt to do with loading the bearings up, it
is to actually elastically deform that huge "bolt" that is the sierra hub. It obviously has to be elastically deformed in order for the
nut to stay tight.

Just had another look - hub nuts are definitely FT and everything else looks ok. I still have the free play but it feels like its 'behind'
a very strong spring, hense my preload queation. I really need someone else to have a look while I wiggle as its not possible on my own.

something amiss I'm afraid, you never really get play in sierra bearings, they just get noisy and then fall apart, but they very rarely fail
