tuskar Posted December 6, 2014 Share Posted December 6, 2014 Hi guys Have an old 2001 legacy estate 2LNA, I feel an excessive amount of backlash when going from over run to drive in all gears .Replaced engine and gearbox mounts and no better. Seems to be a lot of fore and aft play in gearbox when vehicle is moved back and forward. Car has 120k miles Any ideas please Quote Link to comment Share on other sites More sharing options...
stants Posted December 7, 2014 Share Posted December 7, 2014 Hi ,you could change the pitch stop, they wear out after time and induce a bit of drivetrain for and aft movement Quote Link to comment Share on other sites More sharing options...
Mr B Posted December 7, 2014 Share Posted December 7, 2014 Sounds to me me like internal wear in box You want check this by turning prop by hand back & forth & you will feel & here where the excessive play.lash is. Is possible changing oil to quality heavier oil such as 75-120 may help, some custom mix of 2 viscosity oils can also work to some extent to hide the problem & sometimes can do so for very long time. If play/lash very severe then rebuld is likely needed. 120K is low for these sort of issues though but bad gear oil & driver who harsh with clutch & heavy towing can soon cause a lot of lash in a transmission.

tuskar Posted December 7, 2014 Author Share Posted December 7, 2014 Thanks for replies. First after further checks most of the play seems to be in front of gearbox , maybe front diff ? and can hear the knocking when pushed fore and aft while in gear. Will try heavier oil as suggested. Also have a spare gearbox with 70k only but that is a big job swapping and hoping its compatible too. When driving on a flat motorway feels more like I have a 4l v8 under bonnet as engine accelerator seems to control car too sensitive like.???

Mr B Posted December 7, 2014 Share Posted December 7, 2014 Worth looking at pitch stop then like stanton suggested. Also look at driveshaft joints & check play and feel from shafts through the diff. Quote Link to comment Share on other sites More sharing options...
tuskar Posted December 7, 2014 Author Share Posted December 7, 2014 Certainly will check pitch stop Thanks Stanton . There is a little play in front shafts coming out of diff. up/down not rotational and not unlike my other subaru impreza I took legacy car for a 120 mile trip today and it has LITTLE or NO backlash !!! It is intermittent . Can anyone make sense of this please Quote Link to comment Share on other sites More sharing options...
