So i noticed saturday that my rear axle seals were leaking. The truck has 165k on it, I have a diff breather extension so i do not think thats a problem but i still need to check it, its buried in the gas filler tube near the body. But i replaces my seals yesterday along with new brakes. This morning i went out to the truck and they are leaking again..........great. This is after i just did the same project on my sisters 4runner so im really good at it now. So now what do i need to do? i need to get this fixed asap. Do i need to have new baring installed along with the outer oil seal? Is that what is leaking? Any input is great. thanks.

 

Get the upgraded seals right from toyota...

 

Def. check the breather. If it is clogged, it'll let pressure build up inside the axle, forcing oil out past the weakest seal. Could also be the seal was damaged while putting things back together.

 

turns out the baring is shot. getting replaced tomorrow. $410 parts and labor.......

 

verify the outer axle seal part number ends with digit 6-be sure the inner axle seal also done at same time- it better be while it is all apart....

 

could be there is still fluid between the bearing and the outer seal and this is the issue at the moment and you will have to at least get the bearing retainer to do the outer seal!!
