ajh Posted February 16, 2013 Share Posted February 16, 2013 Has anyone run into fairly severe vibration with a newly fitted front propshaft? This one is from a 'major vendor' but not LR original. There isn't any obvious free-play but it vibrates worse than the one I was using temporarily off another vehicle which was clearly extended too far on the spline and you could both see and feel it flexing at the slip-joint. Presumably a vendor is liable if a shaft is shipped unbalanced? Returning it would be prohibitively expensive in this case; do I have the right to a 'local repair' in this case? (it did originate in the UK) Quote Link to comment Share on other sites More sharing options...
Diablo Posted February 17, 2013 Share Posted February 17, 2013 Is it britpart? Quote Link to comment Share on other sites More sharing options...
Maverik Posted February 17, 2013 Share Posted February 17, 2013 How do, Have you got a standard rig? i.e. no lift etc. you say you had a vibration before, are you sure its not been caused by a duff diff pinion bearing or transfer output shaft bearing problem?

ajh Posted February 17, 2013 Author Share Posted February 17, 2013 Removed the shaft; vibration vanished. No play in either pinion or TC bearings both have less than 40K KM on them. It is not a Britpart. I can take the shaft to a local rebuilder on Monday to get it checked for balance; but they can only test to 3K RPM. The vehicle has about 2" of lift; corrected front arms, and the flanges are not perfectly parallel but they're fairly close. The last shaft did not vibrate like this.

Tanuki Posted February 17, 2013 Share Posted February 17, 2013 Check that the yokes on the centre part of the shaft are phased properly; if they're not you need to pull the two halves of the shaft apart where they spline into each-other and rotate the two halves the necessary amount to get the phasing right. [Must admit, I consider the yokes-and-spider universal-joint with its non-uniform transmission-of-angular-momentum as it rotates, to be something which should have been done away with decades ago: proper sealed constant-velocity joints do the job so much more smoothly and put less of a load on the transmission components too] Quote Link to comment Share on other sites More sharing options...
ajh Posted February 18, 2013 Author Share Posted February 18, 2013 Well, they did come from one of the large LR vendors; but does anyone know how much phasing there should be? Presumably with a lift if you shift it over one spline in the right direction some of the vibration should vanish? Quote Link to comment Share on other sites More sharing options...
western Posted February 18, 2013 Share Posted February 18, 2013 this should help. 1 Quote Link to comment Share on other sites More sharing options...
ajh Posted February 18, 2013 Author Share Posted February 18, 2013 Yes, I've seen that. I was wondering if anyone worked out the relationship of phase and lift-delta from stock. Quote Link to comment Share on other sites More sharing options...
western Posted February 18, 2013 Share Posted February 18, 2013 my 110 is slightly raised but just less than 2 inches IIRC, both props are the standard item, haven't had any abnormal out of balance/vibration or UJ issues Quote Link to comment Share on other sites More sharing options...
ajh Posted February 18, 2013 Author Share Posted February 18, 2013 Thanks; yes that's more or less what I thought. I guess I'll need to take it to the shop for balancing to see how off it is and if it could be that. The phase does look to be right. Of course I just discovered that one front shock has leaked out about 1/5th of its oil which explains the odd handling I was getting... (finally) so many possible things to check when things don't feel right. Quote Link to comment Share on other sites More sharing options...
