prop advice needed.

[denviks]

well where do i start. i had a vibration in my disco 200 on the motorway. you can sort of feel it from about 45 ish all the way up. at 70 mph its quite bad. you can feel it through the floor ect but not the steering.  i initialy thought wheel balance so had them done. nope no affect. the vibration is still there. i changed the front uj on the front prop as i found this was very worn with moevement in it. it did make a difference but not a great deal. pux has given me another front prop to try so i will fit that tomorrow morning and give it a go. could it be uj's on the rear prop? the vibration seems to be worse when going up or down hill ....im sort of abit lost now as to what it could be........anyone any ideas?

You could remove the front prop, engauge the centre difflock and take it for a drive. If the vibration has gone then it could be the front prop. If it's still there then put the front prop back on & remove the rear and try again.

can you do that at 45 mph/?.... the vibs really come in proper at 50+

[Budgie]

No reason why not. I saw a chap on the Belgium National last year who blew a rear diff, removed the diff, propshaft and halfshafts then drove back to the UK like this!

I presumed he greased the bearings though

if you drove back with no halfshafts in rear for a long distance, you would run the risk of throughing wheelbearing greese out and water grit etc in. for a test run id say yeah fine, but from belgium home, no way! id rather cut teh end of me half shafts so i could get it home better with bearings covered still  :D

put as you only need to remove props to check what you want, will be no problem with centre diff in.

have fun finding your fault  :D

cheers guys. its doing my head in now. it seems to vibrate under heavey load. if on the flat with a balanced throttle its not as bad but boot it orr hit a hill and it gets worse. the front seal on the flange on transfere box is leaking and there is a tiny amount of play there but no more than a mates one. gonna have another go at it tomorrow. just dont want to blow a diff up aswell

Actually some of the disco's I believe have removable plates like the series, so could remove shaft and replace the covers

I think that was the case with this one.

thanks everyone.....  :D  :D  :D  this morning i took the front prop off. after examining it i couldnt see anything wrong. i changed the front uj on it about 2 weeks ago and the rear one felt good.  :?  but still the vibration. pux gave me another front prop to try. after biting the bullet i fitted it this morning and took it up the motorway  :D  :D  :D  all smooth again. well as smooth as a 200 tdi disco can be  :lol:  :lol:

so i would just like to say thanks to everyone who gave me advice on this......and thanks to pux for the prop    :D  :D  your a gent
