Hey guys so today while driving my '98 Mercury Grand Marquis home I noticed a leak was coming from behind the rear right tire… Or I’m guessing it’s a leak ? But it’s kinda like a grease substance and it sure does smell bad! It’s all over the backside of the tire and muffler (probably why it smells).
While driving it there is a low humming sound? Best way I know how to describe it and if I go over 60mph it gets increasingly louder… After looking up some forums online I came across that it could be a possible wheel bearing or maybe a bad axel problem? Any idea what a rough estimate is on a job such as those ?
