Im new to this site so i hape this is the right place to post this. so when i am in reverse with the clutch engaged there is a rubber sounding ,rythmic squeak squeak squeak squeek, that accelorates as i do. then as soon as i let off the clutch, its gone. it sounds like its coming from the rear end some where. the seal where the drive shaft enters the differential is going bad because there is a small amount of oil around that area that is semi fresh. idk if that has any relation but thought id throw it out there.
