2005 GMC Yukon XL Denali Q&A
2005 GMC Yukon XL Denali Question: leaking power steering between the master brake & brake power booster ?
is your pedal spongy if so you probably need a master cyl - goodguy
if your leaking p/s fluid it must be a hydraboost system. poss hydraboost rear seals are bad - globalhelper
