Re: grease leak toyota 4runner 1996
You need to disconnect the rear wheel cylinder brake line and pull off the rear backing plate, via the 4 bolts that are visible after you remove the brake shoes. One the backing plate is loose, take it down, out of the way, and pull the axle shaft straight out. You will need several parts from a Toyota Dealer, and a machine shop to press off the old bearings and seals, and to press on the new bearings and seals. Go to the dealer & tell them your problem, we do this job once-twice a week; a common issue. The only seal that you can change yourself is the axle tube "outer" seal, you will see it when you pull out the shaft. But, this seal is not the cause of your leak. The inner seal on the shaft is worn. You will also need to replace the oily brake shoes, too. Hope this helps. A FIxYa rating would be appreciated.

Each side has a wheel cylinder with a hydraulic line connected to it,when you push brake pedal,they push the brake shoes against the drum to stop,yours,may be leaking,to see,you need to remove drums,they are at the top with 2 screws holding it on.Here's a link on how to replace them.
Since you were just working in the general area. I would check all wiring connections underneath, and around the axle! It's a common happening, bump a connector without realising and things happen! Good luck
Leaking oil at the rear wheels can be one of two things, Easy fix is brake fluid, this would be the rear brake wheel cylinder leaking. Check your brake fluid tank under the hood for low fluid. If that is ok. Your leak may be your rear axle shaft seal. You need to remove the tire/wheel ether way. Jack up the car to pull the wheel, take your lugs loose while the tire is still on the ground, it is easy to take them loose this way. Take the EM: brake off, and jack up this side of the car. Your car could have disk or drums as both are offered on some Dodges. Once the tire is off you will see if you have disk or drums brakes. If drums you will need to pull the drum off at access the brake cylinder to see if that is leaking or not. If drums you have to back off the brake shoes by the adjusting wheel thru a small access window in the back plate. If you have disk brakes the caliper is right there and will be easy to see if it is leaking. If you have determined it is the rear axle seal leaking, this may be best done by a shop, due to needing a few special tools to remove the axle and then reinstall a seal. You will need a slide hammer. If drum brakes you will have to remove the brake backing plate, this means shoes and all hardware, please take pictures and get as good focus as you can to see how everything goes back together. Once down to the axle mounting, remove the 4 bolts and attach the slide hammer and pop out the axle, catch any fluid that will leak out, once out you can determine which type of seal set up you have as some have press fit collars that may have to be cut off. . Hope this helps FixYa up.

Section 04-02: Suspension and Wheel Hubs, Rear
1996 Escort, Tracer Workshop Manual
REMOVAL AND INSTALLATION
Wheel Bearing and Hub Assembly
NOTE: Wheel bearings are not serviceable and should therefore be replaced as an assembly with the wheel hub (1104).
Raise and support the vehicle.
Remove the wheel and tire assembly.
Remove the hub grease cap (1131) from the wheel hub.
If equipped with disc brakes, remove the rear disc brake caliper (2552) and rear disc brake rotor (2C026). Refer to Section 06-04 for the removal procedure.
If equipped with drum brakes, remove the two brake drum screws and the brake drum (1126).
Unstake the rear axle wheel hub retainer (4B477) securing the wheel hub to the rear wheel spindle (4A013). Remove and discard the rear axle wheel hub retainer.
Looks like you have a bad wheel speed sensor. I would pull the rear wheels off, and the brake drums. Look for grease leaking inside the drums, at the center. If so, your rear axle seals are bad...common issue.
It appears the rear axle shaft seal is leaking. You will need to pull the axle and replace the seal. Then check the rear end for adequate gear oil. The iron filings I am not to sure about. It sounds as if something came loose from the brakes or brake hardware and got chewed up in the drum. You will need to replace the brake shoes and maybe the brake hardware kit. Always change the shoes or pads on both sides when working on brakes, rear or front. If the inside of the drum is not perfectly smooth it will need to be turned or replaced. If this were brake fluid leaking from the wheel cylinder the master cylinder would be low on fluid and your brake pedal would go down much further than normal.
soft(low) brake pedal has 5 possible cause
1 air in system
2master cylinder bypass
4rear brake shoes out of adjusmet(too far from drum)
5spongy brake pads
if there is no leak and the fluid is at level I would adjust rear brakes and bleed system.If that did not work replace master cylinder.
If no oil on the driver side, you have a locked up parking brake pivot. Follow the park brake cable to the inside plate of the rear wheels. on the outside, where the cable connects, look to see the position of the visible mechanism connected to the cable. It probably will not match the side that is not locked up. This is a very common problem; you need to replace the park brake pivot. Additionally, you are going to need to remove the other side axle shaft and get the leaking oil seal replaced. Replace the brake shoes if they have oil on them.
