Land Rover Repair: Steering system, steering damper, steering boxes

Question
Hi! I have a leak in the steering box and vibration of steering column. Vibration depends on the road condition not the speed. Do you think both problem are related?
I have steering box seal kit. Does it have to be replaced by an expert?
Do you think vibration is caused by ball joint or steering damper or panhard rod damaged?
Thanks a lot for your information!

Answer
The leak in the steering box is probably unrelated to your vibration.

The seal kit should be installed by someone with the necessary skills.  But in my experience installing seal kits on Rover boxes seldom works out.  That's why we just install rebuilt steering boxes.
