screwbaru2 Posted January 12, 2008 Share Posted January 12, 2008 I replaced the driveshaft on my wifes 99 impreza 2.2L coupe auto trans no abs. The driveshaft could not be removed from the knukle. Normally I just back off the nut flush with the face of the cv shaft and tap it till it starts to move. Not this one!!!! After much PB and time I took the knukle off the car set it up so I could hit it with a 16 lbs sledge! I was not able to remove the shaft from the kunkle. Had to go to a bone yard and buy a knukle. This has never happened to me before. I've done hundreds of driveshafts and have was always been able to get these out. What gives has anyone else out there had this expereince? Any ideas on getting it out? The bearings I'm sure are shot ( I hit this thing HARD many times) but the knukle looks useable. Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted January 12, 2008 Share Posted January 12, 2008 It's rusted into the hub. Water may have gotten in there somehow and corroded it. It's surprising how little rust it takes to make it nearly impossible to separate them. Coat the new axle splines with grease or antisieze to make it easier to get out if it needs to come out again.

nipper Posted January 12, 2008 Share Posted January 12, 2008 Heat up the yoke. A toruch will get the metal on one side to expand more then the other, breaking the grip that the rust has on it. nipper Quote Link to comment Share on other sites More sharing options...
screwbaru2 Posted January 12, 2008 Author Share Posted January 12, 2008 nipper, I was considering heat at the time but was afraid that the bearings would have been damaged. Like I said at this point the bearings are junk any way so it doesn't matter but you think heat would have been ok to use. I was surprised at the time because this had never happened to me before. Just lucky:rolleyes: I guess. Thanks nipper Quote Link to comment Share on other sites More sharing options...

Thanks porc, It's hard to see how water can get in there but I'm sure it can. I use anti-seize on everything that doesn't require something eles. Works better than grease. Even use it where the wheel contacts the flange on the hub. After I work on it doesn't rust together.Ever. Quote Link to comment Share on other sites More sharing options...
Skip Posted January 12, 2008 Share Posted January 12, 2008 "Even use it where the wheel contacts the flange on the hub." plus 1 K on that one!! The Subaru hub-centrics (incl. alloys) really get stuck on!! Note this is on the rust coast. Quote Link to comment Share on other sites More sharing options...
