i've got some steering play when i turn, not much but enough to annoy me

what could cause this ? Power Steering pump or pitman arm ?

also for rear shackles, top part it has a bushing, will the moog sb335 leaf spring bushing replace that bushing so i can remove the rust welded bolt in there so i can insert my lift shackles ?

Thanks

 

I am not sure on the moog part...maybe check synergyoffroad.com they sell bushing kits for the leafs
I would check your idler arm first...however if the idler arm is bad and has been for awhile it could have worn your pitman arm as well
