Hi there,
I feel that they may be referring to excessive wheel bearing play, (with the wheel jacked up there should be no movement of the wheel rocking it top to bottom) this is a big job and there are special tools required, this is best left to a qualified mechanic, as for the coolant leak, there are about 6-8 different hoses on the engine, so with out seeing it I can't tell you which one it is.
