hi there got myself a 2005 d22 navara in feb had a new engine put in 20k miles ago as apparently that year had a fualt on the engines that liked to send the pistons throught the bonnet or some such thing. as soon as i got it i took it green laning to see how it did and was very impressed i also whack the enduro bikes on the back when i go racing and laning . only problem im having at the moment is very bad vibrations at between 40 -60 mph that go away once i get over 60 ive got new tyre and rebalanced and done the tracking but its still there. after searching the forum it seems it may be the front props ?? but still cant find a walkthrough talk through how to take them out of check them to see if it is them .
