98 DSE on 208,000 miles with original engine. Just did a big service with the help of my mechanic acquaintance, changed engine oil, diff oil, auto box oil and filter, put in a used viscous coupling, new 1000ccc diesel spec battery, replaced injector leak-off pipes, new beru glow plugs, new inlet manifold gaskets, replaced 3 gaskets in fuel injection pump, re-calibrated the FIP, dropped the fuel tank and replaced in tank fuel pump. Now works great.
You didn't grease your prop UJs - hah, call that a service!!!!
