sixtwoeight Posted February 14, 2012 Share Posted February 14, 2012 Hi everyone, My 1997 disco just failed its MOT on the dust covers for track rod end ball joint. The tester showed me and yes they were split and perished on both sides. He called it the drag link - but it was on the longer track rod bar behind the axle (i thought the drag link was in front of the axle). can someone verify which is which please. Secondly, today I ordered 2 track rod ends, one LH thread and one RH thread, but am now wondering if: Are the trackrod ends the same for the drag link and the track rod bar? (i.e the two in front and the two behind the axle) They do look the same as far as i can see. Or are there different TREs for drag link and TREs for track rod bar? I just want to make sure I've got everything I need before I start doing them as its my daily driver. Thanks for any comments. Quote Link to comment Share on other sites More sharing options...
Les Henson Posted February 15, 2012 Share Posted February 15, 2012 You have 2 left hand thread and 2 right hand thread TRE's on your Disco (one of each on each rod). Got one here at the minute that's failed on all of them All TRE's are otherwise the same. Les. Quote Link to comment Share on other sites More sharing options...
BogMonster Posted February 15, 2012 Share Posted February 15, 2012 The Discovery 1 uses the same ends for the drag link and track rod but while I'd need to check a parts book to be 100% sure, IIRC there should be three of one and one of the other: - Drag link (for steering box drop arm to axle) has two RH thread ends RTC5869 - Track rod (between the two front wheels) has one LH thread RTC5870 and one RH thread RTC5869 This is so that when you loosen the locknuts and adjust the track rod you adjust the tracking. On a Defender, the steering box drop arm uses a different joint, used to be STC3295 but I forget what it was superceded to. HTH Quote Link to comment Share on other sites More sharing options...

teabag Posted February 17, 2012 Share Posted February 17, 2012 Wrong & wrong again: For a 97 disco, drag link near side end is LH thread, drop arm end is RH thread, and track rod both ends are RH thread the mid track rod adjustment no. 3 has a LH thread.

Niamh Posted February 18, 2012 Share Posted February 18, 2012 Wrong & wrong again: track rod both ends are RH thread the mid track rod adjustment no. 3 has a LH thread. Unless one has fitted a heavy duty track rod In which case its 1 LH & 1 RH. Niamh Quote Link to comment Share on other sites More sharing options...
