Virdi Posted August 29, 2014 Share Posted August 29, 2014 Hi, This is the front diff (which I have just rebuilt with new bearings and grease etc...) But I am getting slight back and forth movement ...is this normal? Thanks Quote Link to comment Share on other sites More sharing options...
53HRA Posted August 29, 2014 Share Posted August 29, 2014 There is always a tiny bit of play between the shaft and cup(s). Worst case you can fit a small o-ring into the holder to stop it rattling - Providing it's all built up correctly and runs smooth it's nothing to worry about Quote Link to comment Share on other sites More sharing options...
Carlton Posted August 29, 2014 Share Posted August 29, 2014 There need to be a very slight play there as you are feeling the mesh between the output shaft bevel gear and the diff ring gear. Bit like you need a very slight play between spur and pinion. Quote Link to comment Share on other sites More sharing options...
Tamiyacowboy Posted August 29, 2014 Share Posted August 29, 2014 yeah the lateral shift is ok , its there to help bed the internal diff mesh under torque and load. the output shafts leading to dogbones and wheels are a key area, these move in and out to but sometimes we add a shim to stop to much lateral movement on the output shafts. the input shaft ( the area your had a worry over ) if this starts to sway left and right, the bearing has blown out or the bearing carrier ( where bearing seats) has become worn. just go easy the first couple batterys, to help lay those meshes back and get everything settled in the gearbox-transfercase Quote Link to comment Share on other sites More sharing options...
