Hi Suresh,
Do Prado needs a Spindle reinforcement, since most of the part of the FJ's are identical to Prado's?
Good question. Thought they share many common components, I am not sure if the Prado also requires a spindle reinforcement. Have not come across them, t be honest.
But, since both vehicles have similar setup and engines, I would rather have the spindle reinforced, rather than risk it.
Reckon those with Prado will be able to provide better details. This is just a unstudied opinion of mine.
