One more does anyone know the weight distriburtution of the 4Runner? 40/60 30/70? Any help would be great assitance. Thanks again guys

knuckle and spindle hub and bearings is around 35 pounds

4runner    um about 60-40  for a runner

about how much extra would the 31" A/t tire with a steel rim weigh along with the brake caliper? or is the 35 lbf including the brake caliper?

How much does the entire rear axel weigh?

Instead of starting a new post for each question, why not ask all questions in one research link. Fill us in, tell us what ur doing. Keep it in one link so that it is easier to search and quick for all to learn from???
