i just changed the drivers side axel.found out real fast why the axel was bad. because the inner cup has a peice in the bottom of if that came out and the tranny shot fluid into the axel through the sleeve that goes over the shaft .so i replaced the shaft and made sure the peice was in place but i couldnt get it to lock into postiton so i thought and put the retaining clip into the axel side inside the grove and put the axel on butv could not get theaxel past the clip to set it into place.anyway the axel is in and i took a test run and im still hearing a thumping noise comming from the front sounds like the drivers side. dont know what else it could be.i did notice that the output shaft on the drivers side had some play in it while i had the axel out. how much play should it have.should i check the hub on that side. i replaced the hub about 2 years ago. my abs and trac controll lights are on.i know that i should get it scanned and i will soon just asking if im in the right area of thinking. thanks for the responces and hope to help someone else soon.jeff
