the engine was fine, was removed from my dads range rover that died of rust. props have minimal play, but nothing prop wise was touched, i just pulled the engine out. even on tick over its vibrating everything, slight revs and it smoothes out a tad. i have had the floors out loads of times, and it never made this kind of noise when the old engine was in. i will try pumping more greese into the uj's and see what happens then. i do know the front diff seal and bearing is on its way out, tho again fine when old engine was in. Also today i changed the front transfer box bearing and seal.
