So I noticed a fluid running down my passenger side tire, found some inside wheel and down tire and discovered it was diff fluid, must be leaking out somewhere near brake drum Is there a seal that goes bad or something that would cause this? thanks in Advance,
Dave

 

Yes there is a deal inside and it is common for them to go. Never had to fix one myself so I couldnt tell you how hard it is to fix.

 

yes there is an axle seal at the end of the tube , pull the axle and you will
see it .

 

Could be a wheel cylinder leaking too. If it is the axle seal, take a real close look at the axle shaft where the bearing rides, if it is scarred or worn you need to replace the shaft and bearing.
