Just wondering what's the average life for the u-joints on a Disco 1? I'm at 120k and assuming they've never been replaced (which is probably true given the lack of maintenance on it) I know they won't last forever and just thought maybe it would be good preventative maintenance.

i'm at 190k and am pretty sure they are original, will be replacing when it's not below 0 degrees outside

 

If they are greased twice a year and if you are not doing lots of water crossing, they can last a long time. That being said, they can fail in a heart beat also.
With your mileage, I would replace all of them quickly.

 

Guess you're right... better to do it now than on the side of the road. Since maintenance was never a priority for the PO and since I found water inside the CDL tower then I'll get it done.
Stupid question but how many do I need? I didn't check that out when I was last under it and it's only 5 out there!! Should I replace the flex coupling while I'm at it?
