I have a 98 GMC Jimmy leaking fluid, can u help?

[Pallee Girl]

It's leaking a fluid (possibly brake fluid) from the rear passenger tire. It's coming from inside & seeping down on the rim to the ground. About a pancake size spot on the ground now. My brake fluid isn't low & my brakes are working, but what do u think this is? I haven't driven it since i noticed it a week ago. Any advice is greatly appreciated.

It could be the axle seal leaking your differential fluid or the wheel cylinder or caliper leaking brake fluid.

If your not losing any brake fluid then there is a good chance that it's your axle seal. There should be a strong smell of oil from the wheel if it's the axle seal, at best there is nothing wrong and a dog calmed your jimmy's tire. LOL Be most likely it's your axle seal and any transmission shop can replace the wheel seal and have the axle bearing replaced too since it's right there and a worn bearing will cause the seals to fail. Good luck
