Re:brake job
sounds like to me they busted a seal inside of the axle tube. Check to see if you are leaking gear oil out of the axle tube by the "u" joints, if so then it is a seal. <br>Someone else will jump in and they can give you more detail<br>

Re:brake job
Are you sure it is gear lube and not Brake fluid? Also is it just one wheel or both of them. <br><br>ANY TYPE OF OIL OR GREASE on the rotors can cause immediate brake failure. At best they will hang up with a small amount or worse case fail completely.<br><br>The axle seal on the passenger side is internal near the CAD vacumm shift motor toward the center of the front differential housing. If it leaks it should not be reaching the rotors but rather running out the axle jousing down the knuckle and lower ball joint. <br><br>These particular seals are bad for going out and are a real bear to fix. Unless you are really good with difficult wrenching work. You need to have it done.<br><br>Check the level of your brake fluid and determine if you are leaking brake fluid. If you are DON'T DRIVE THE VEHICLE!. Improperly repaired or damaged calipers can leak and cause you to lose braking ability. Call for the tow truck and get it to a reputable shop.<br><br> You should be able to tell the difference by the smell between the fluid and grease. Both have very distinct aromas. Take note to be very careful and wipe the lid on brake fluid reservoir clean before removing it. Any foreign material entering can damage the system. Also Brake fluid is corrosive to paint and other materials so don't spill it.<br><br>That is the best I can do without more information Good luck!<br>

Re:brake job
If you determine it is gear lube, just be patient it should stop in 2-3 weeks. If the seal is not damaged. Jack up the truck on 1 side and let it sit for a couple hours and then do the other side. If they pulled the axle out and the truck was tipped the gear oil spills over the seal and fills the tube. the seal is right next to the pumpkin so the axel tube can hold a lot of gear oil. good luck.jd

If the seal is not damaged. {...}<br>[/quote]<br>IFF he's lucky and it's just overflow past the seal(s). If someone went to the trouble to pull the axle(s) out, they should've cleaned the axle bore before putting back together. Not necessary to pull the axle in most cases. so many people leave them hanging. Problem is (especially on the CAD side) by letting the axle droop to the bottom of the bore, you are using the seal as a fulcrum to try to hold up the axle shaft in the housing. That deforms the seal, probably permanently, and allows it to start leaking especially when the oil is hot. It may take a while for this to happen. When I pull my rotor/hubs, I always stuff a rag or some foam rubber in the axle tube (under the axle shaft) to support the axle in the MIDDLE of the tube. This way, the seal is not put under undue stress. I discovered this the hard way, so know from experience!!<br><br>I don't see how gear oil got onto the rotor though, unless it was just pouring. I've had mine leak for months before, and never even came close to getting it on the brakes (just dribbles down on the lower ball joint). <br><br>-Scott A.
