Hi Jon , My td5 is at 269,000 km original clutch , must say It's about ready for replacement , like you I can do It myself . My truck pulls my caravan , has lugged car trailers loaded , done lots of high country driving in low , and is still going . So for me It's a DMF . It my well be I could just change the clutch and pressure plate . I've heard when the DMF let go It can be messy . In saying that I have the complete kit , including DMF and a new spigot bush , It's on my list of things to do !!.. Jim
