Guppy Posted September 2, 2009 Share Posted September 2, 2009 Hi guys - just a quickie: Front prop orientation: - Is the sliding joint meant to be at the axle end or the t/box end? Cheers! Guppy Quote Link to comment Share on other sites More sharing options...
Deface Posted September 2, 2009 Share Posted September 2, 2009 I have always been told to put the slider the t/box end, so it is away from the mud and dirt when offroading. ethan Quote Link to comment Share on other sites More sharing options...

defender dinky Posted September 2, 2009 Share Posted September 2, 2009 hi,just done this , and in haynes it said defender td sliding end to face axle on the front t/box on the back, but on the 200tdi sliding ends both to t/box according to haynes, although i don't no why nothing to do with mud and water, might be somthing to do with vibrations. cheer's defender dinky Quote Link to comment Share on other sites More sharing options...
Guppy Posted September 2, 2009 Author Share Posted September 2, 2009 Ah right. I missed that bit in the Haynes. I've just replaced my Front Prop after a swapping from a N/A to a 200tdi. I replaced it exactly how it was and am now getting vibrations. My sliding joint is currently at the axle end in what must be the N/A configuration. So for 200 tdi it's the other way around: Slider at the T/box. More grubby fingers this weekend then! Thanks guys! Quote Link to comment Share on other sites More sharing options...

The front prop sliding joint is towards the axle, as it was with the TD. Thinking on it, the Disco I robbed had the slider at the t/box end. Thought it was just a "Land Rover thing", perhaps there was a reason for it after all! Quote Link to comment Share on other sites More sharing options...

Searched my Haynes manual today and can't find where it says this for the 200tdi, I assume it is in the "prop. shaft" section? Also, looking at Rave (300tdi Def)it does state slide to the t/box, and also that the uj. yokes should be "out of phase" by (looks like) 45o, due to the short shaft and angles involved. Can anyone comment further? Quote Link to comment Share on other sites More sharing options...
defender dinky Posted September 3, 2009 Share Posted September 3, 2009 hi, in the discovery haynes manuel the 200tdi propshaft slide end t/box on the front same as the back, defender manuel slide end to the front alxe for defender,[i have both manuels]the yokes on the front prop should be about 35 degree difference, on the back they should be in line defender dinky Quote Link to comment Share on other sites More sharing options...

Guppy Posted September 6, 2009 Author Share Posted September 6, 2009 Looks like I've opened a right can of worms here! Are there any grown ups who can show us the way? :-) Quote Link to comment Share on other sites More sharing options...
errol209 Posted September 6, 2009 Share Posted September 6, 2009 Looks like I've opened a right can of worms here! Are there any grown ups who can show us the way? :-) A universal joint is only a constant velocity transmission device when both shafts are in line. At any degree of articulation (and worsening with the degree of "bend") a UJ will cause the output shaft to speed up and slow down fractionally from the input shaft's rate of rotation. This is why CVs (constant velocity joints) have replaced UJs for front wheel drive cars, as all series owners will testify. For a prop shaft with two UJs at high degrees of articulation, if the UJs are lined up appropriately, it can experience a point in its rotation where the "speed up" points for both UJs are co-incident, meaning double the problem. It therefore makes sense for the two "speed up" points to be set as far apart in the shaft's rotation, e.g. opposite each other, or failing that 90o apart. It makes no difference to this explanation which end you put the sliding joint. Quote Link to comment Share on other sites More sharing options...
western Posted September 6, 2009 Share Posted September 6, 2009 front & rear prop sliding joints should be at the transfer box end. Quote Link to comment Share on other sites More sharing options...
