front prop

hi fellow landy lovers,got home tonight and decided to take front prop of so i could see if it rattled on the way to work tomorrow as iv been having issues at 50mph,went to take it for a quick spin to see if it made a difference and couldnt get of the bloody drive lol am i right in thinking its left and back on the little gear stick i do plan on putting the prop back on tomorrow after im back from work(and yes 1 of the uj's had a bit of play in it so im hoping its that) but i need to get to work and didnt get time to change uj's and get it back on,thanks in advance

you do need to engage difflock by pushing lever left

thanks mate for the reply i did think that but didnt want to mess up,just popped around the block and no rattle so i was right about the uj's, i have managed to change them just ran out of time to fix the prop back,one more thing how fast can i drive in diff lock is 50-60mpm ok for a day or so

so iv managed to get the prop back on over the weekend and changed the 2 uj's but i still have a shaking,it not as bad as it was but its still there,could the prop need replacing or am i missing something?
