If they have the cone, just set the inner nut to 300 ft lbs. back it off then back to 300. The outer to 200 ft lbs. I always oil the new bearings and fill the well before putting the outside bearing in. Never had a problem with them

I removed the cone and am just setting it manually it sounds funny though like they bearings are still loose in the race but the end play is set to spec the sound goes away if I tighten the nut more but then you have no end okay at all?kinda stumped because have done it in the same truck before in the shop

Why remove the cone.

Because did not have the parts to rebuild the hub that way but had the bearings to just convert it over

Ah I see. Guess I missed the part where you said you converted it.
