nobber Posted April 11, 2007 Share Posted April 11, 2007 when i put power down it has to pick up a lot of slack before delivering that power to the wheels. also when i power off it has to pick up the same slack before slowing down. this is very noticeable when changing gear at any speed and when I'm in heavy slow moving traffic its like Ive got kangaroo juice in there. its not something i can live with nor can i just dismiss it as 'one of those land rover things' , somethings not right down there. so , how do i check an axle for excessive play in the drive train? is there a process of elimination? axles and gears are way above my head so any input would be greatly appreciated as i need the old girl on the road by friday to get me to work and back.

nobber Posted April 11, 2007 Author Share Posted April 11, 2007 its in the front axle. Quote Link to comment Share on other sites More sharing options...
Yostumpy Posted April 11, 2007 Share Posted April 11, 2007 nobber you could try taking the rubber end caps off the drive members, jacking each corner up in turn and seeing how much slack you've got in the splines, changed all 4 drive members on mine, and 75% better, can live with 25%, it might not only be the fronts only but the whole system playing "catch up" Quote Link to comment Share on other sites More sharing options...
Ex Member Posted April 11, 2007 Share Posted April 11, 2007 Why do you believe it is the front axle?? It could be many places. It could be in the suspension. Quote Link to comment Share on other sites More sharing options...
nobber Posted April 11, 2007 Author Share Posted April 11, 2007 cheers for the reply guys. its defo the front axle as its a really loud 'clonk' when it picks up drive , also i had a friend drive it whilst i watched from out side and i saw the front wheels jolt as the clonk took up the power. all the bushings are new , the steering ball joints are all new , one bearing has been done reciently and its just bed in and need a final adjustment but the swivels have all been done and everything seems solid enough. ive just put two new uj's on the front prop as well. ive got about a quarter turn on the front prop but im told this is normal. its happening somewhere between the front wheels and the tranny box.

FridgeFreezer Posted April 11, 2007 Share Posted April 11, 2007 Drop the prop and see if the slack is in the transfer box or the axle (or the prop splines, or some in everything). There are loads of places slack can appear and the combination of a few of them can give a really big overall amount of slack. The front wheels jolting is not necessarily an indication that they're where the slack is, if the rear is slacker than the front then (in theory) the front may take up drive and jolt before any power actually gets to the rear.

FridgeFreezer Posted April 11, 2007 Share Posted April 11, 2007 Remember as well that play is amplified - a diff is 3.54:1 so a small bit of slack in the half-shaft splines will be 3.54x more by the time it comes to the pinion, that's without the slack in the diff, pinion, etc. on top.
