Major front shaft play!!!

Had a clunking from when I brought it (typical) an got under today to investigate, seems theres a good 1/2 turn (1/4 each way) in the front shaft.

I am very mechanically minded an would like to know how an what to repair/replace. Preferably with pictures/links/guides but any help appreciated.

UJs first then its down to backlash in the diff and tranny box, a fair bit of free play is not unusual, what is the 300 in disco or def?

as said have a look at busters how to on the UJ replacement and take it from there.

Its a 300tdi with 157k. The ujs feel fine apparently? (took it to a local driveshaft specialist)

Unsure but looking at new diffs (worst case scenario) how do I find out what spline diff/shaft do I have?

Can you check on another Landy how much play is there? They all have a certain amount of movement when twisting the prop.

I would have thought that if its got too much then both ends are gone, IE the diff and the transfer box.

You should have a 24 spline diff by the way.

My neighbour has a 300tdi so I cn check for a comparasion.

Really hoping its just the diff, thats more than I can realistically do anyway. How will I know if its the transfer box aswell?

How can you be sure its a 24 spline diff?

backlash in diffs can be adjusted by tightening spider nut inside diff

Do you have to strip the diff to get to this spider nut? You you have a link or guide to this?

i just changed the hardy spicers in the ujs and it seems to be alright now.
