vibrations and shudders

<< < (2/3) > >>

clbarclay:
Another for front prop.

Lifting messes up the angles of the UJs on the front prop, the more you lift the worse it gets and then castor correction radius arms or bushes rotate the front axle making it even worse.

As standard the UJs weren't exactly balanced, but they were close enough for vibrations not to be noticed. The more you lift and/or castor correct, the more noticeable the vibrations become.

digger:
now gone down to a 2inch lift and still shudder when slowing down at normal speed fine

Budgie:
Remove the front propshaft, engauge difflock in High range and then take it for a spin and see what it's like.
If the shudder has gone then you know what's causing it, if it's still there then you can start looking at other things like swivel bearings, CV bearings in the back of the swivel housing etc.  ;)

Range Rover Blues:
Front prop.  It's worse when you slow down because the transmision is coasting so all the backlash allows the rattling/droning.  Under load the backlash closes up.
