 shocks are weak on the 4runner SR5. pushing down on rear and front ends causes continuos bouncing, as doeslittle hills on the road. My rear passenger had gotten motion sickness from the bouncing . The truck front end dips on braking and any fast emergency braking causes the front end dip to be so excessive that the rear end lifts the tires up enough to cause the automatic braking to kick in. This has happened to me 3 times and is very scary since the abs brakes stay engaged for a min.I almost crashed into car in front of me . I showed the dealer service dept the problem, but was advised that if they exchanged the shocks for Bilstein shocks, toyota would charge them for the ones removed
