hi can some one shed some light on my problem ? when driving my zafira at speedsa over 30mph i get a loudish humming noise from the front end. the car has been jacked up and checked for any play in the wheels but there isnt any ! removed both c.v boots back to check for grease and it has plenty ! there is a slight leak of gearbox fluid on the end of the drive shaft gearbox side but other than that im baffled as to what it could be
wheel bearing / driveshaft / c.v joint / maybe low gearbox fluid
anyone had the same kind of problem am more than capable of replacing the parts myself but if i put it in a garage they try to rip u off so would rather save my money and do it myself. any help would be aprreciated its a 1.6 16v 1999 model. thanks.
