Hey guys,
My ball bearings need to be replaced. Whenever i would reach 80MPH, a loud VHOOMING noise would come from the bearings in one of my rear tires. After alot of highway driving, the sounds starts a 40MPH now.
I took it to the mechanic and he said "Yeah, its the ball bearings."
My dad's telling me that I don't need to fix it till it breaks.
So i wanna know, are the ball bearings one of those parts that need to be repaired as soon as there are signs of rupture or can i wait till thy're broken????
