msmithmmx Posted August 10, 2016 Share Posted August 10, 2016 Just rebuilt tail housing on the transmission. Now I can hear other things going on. This is a 98 OBW 250k. Are there races in the front end of the rear differential that gets noisy? I do have some rust there. Here is a clip I recorded with back wheels up in the air a little and I was spinning the wheels. Sounds like it is coming from where the drive shaft connects to the differential. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted August 10, 2016 Share Posted August 10, 2016 What was wrong with tail housing? grab the front snout or driveshaft and shake it or pry on it with something and see if it has play? It's definitely internal and not external rust it rubbing? Not driveshaft? Quote Link to comment Share on other sites More sharing options...
msmithmmx Posted August 10, 2016 Author Share Posted August 10, 2016 I had the 16 flashes, bad torque bind, bad gas mileage, slamming into park, hard shifting. All fixed. Now that things are quite in the center I can hear that from the rear. No play on the drive shaft. Maybe rust. Are there bearings back there that wear?

Fairtax4me Posted August 10, 2016 Share Posted August 10, 2016 Something is dragging on the driveshaft. Heat shield or maybe a rock. Quote Link to comment Share on other sites More sharing options...
msmithmmx Posted August 11, 2016 Author Share Posted August 11, 2016 (edited) Nothing from the heat shield. Maybe a rock. I am going to disconnect the drive shaft and spin it. I have a gut feeling the roller bearing 806325020 is worn. Maybe even the entire flag is rusted out. Part for that is 38358AA000.

Fairtax4me Posted August 11, 2016 Share Posted August 11, 2016 If a bearing was worn you would probably have some play in it somewhere. Sounds to me like something is dragging on the tube. There's a support cover just in front of the diff and could have a rock or something stuck in there rubbing on the tube. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted August 11, 2016 Share Posted August 11, 2016 good video, i wasn't ablet to listen to it til today. sounds like it's external more than internal - like something right there at that rusted flange is rubbing. run it and wear that rust off!!?!? LOL did the car sit for an extended period of time? if a bearing was making that much noise turning by hand i'd expect some other symptoms - hard to turn, grinding, play...
