when i put new 32x12.50R16 wheels it had a play ..
after working on that i changed the Caster Bushes (iron man) as my Rig was 2" uplifted and front angle was not correct.
next step was correct alignment (toe/camber), bushes replaced and check the steering damper too .. may be need replacement.
all checked aboved & replaced with new items.
and then BABA Jun Jun KA CAMATKAR Huwa & play was gone
