ettev Posted May 15, 2011 Share Posted May 15, 2011 On my sons EA81 wagon the transmission just began clunking. It's not a grinding, but an actual clunking when driving in normal 2WD. It's especially prominent just after shifting gears or corning, but it really does it all the time in 2WD. If we pop it into 4WD the clunking goes away and all appears well. Whats going on? 4WD not fully disengaging? This car is lifted 4" and nothing was really done to modify the 4WD lever or linkage. Quote Link to comment Share on other sites More sharing options...
desertsubaru Posted May 16, 2011 Share Posted May 16, 2011 Sounds like one of your front axle nuts are loose. Quote Link to comment Share on other sites More sharing options...
ettev Posted May 16, 2011 Author Share Posted May 16, 2011 Nope, but ironically the inner CV boot was ripped on this side. I thought thats what the noise was and replace the whole CV shaft. All nuts torqued to spec and still the noise remains. Quote Link to comment Share on other sites More sharing options...
987687 Posted May 16, 2011 Share Posted May 16, 2011 Probably the driveshaft. When it's in 2wd the driveshaft is freewheeling, when you pop it in 4wd it's being driven. So it's putting different force on the joints. It will stop the clunking. When mine went, that was the exact symptoms I had. Quote Link to comment Share on other sites More sharing options...
ettev Posted May 16, 2011 Author Share Posted May 16, 2011 987687........did you just change the u-joints or the whole drive shaft? Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted May 16, 2011 Share Posted May 16, 2011 I concur - sounds like bad u-joints in the driveline. They will often go silent when in 4WD but will clunk around quite a bit when in 2WD. Just change the u-joint. They are about $25. GD Quote Link to comment Share on other sites More sharing options...
987687 Posted May 16, 2011 Share Posted May 16, 2011 I changed the driveshaft because I traded one with bratman for a computer. Or something... but I was ready to replace them. You have a single piece, so you only need two joints. Quote Link to comment Share on other sites More sharing options...
ettev Posted May 16, 2011 Author Share Posted May 16, 2011 Thanks all. I'll grab 2 new u-joints and pop them in. Quote Link to comment Share on other sites More sharing options...
987687 Posted May 16, 2011 Share Posted May 16, 2011 Thanks all. I'll grab 2 new u-joints and pop them in. Read up on it... they don't exactly just pop in. Quote Link to comment Share on other sites More sharing options...
ettev Posted May 16, 2011 Author Share Posted May 16, 2011 Read up on it... they don't exactly just pop in. Can't be that bad, they just press out of the yokes like all the older car u-joints, right? Quote Link to comment Share on other sites More sharing options...
NoahDL88 Posted May 16, 2011 Share Posted May 16, 2011 Nope, the old Subies use staked caps not snap ring caps. Quote Link to comment Share on other sites More sharing options...
ettev Posted May 16, 2011 Author Share Posted May 16, 2011 So how do they differ than the snap ring retainers? Quote Link to comment Share on other sites More sharing options...
