How can you solve an uncontrollable wheel judder on a Spanish built Nissan Patrol every time you hit an undulation in the road?

Answer 1

one way is take it to an alignment shop and get the worn/damaged parts replaced and realigned. Is it front wheels or rear? One side or both? Do it at any speed or certain speeds? does it pull to one side when NOT "juddering"?

I have the same problem but can describe it in more detail. 1. The problem normally appears at 60 km/h but gets worse at 80 km/h or more. 2. The patrol handles perfectly off-road and only suffers from this problem on the tarmac. 3. The problem is more likely to occur when the vehicle is going downhill. 4. The vehicle does not pull to one side when driving or under breaking. 5. During the vibration the vehicle keeps a straight course but will not stop juddering until the vehicle comes to rest. 6. The problem gets worse if the vehicle is cornering. 7. Juddering is normally provoked by passing over a dilatation joint crossing the road. 8. The juddering moves the front part of the vehicle from side to side and violently judders the steering wheel. It feels like you have a front wheel blow-out.

If anyone can tell me what is wrong I'm sure it would help everyone else as well. This seems to be a pretty common problem.

had the same problem - very frightening on a mountain road in Norway! make sure front wheels are balanced, but mine was solved by changing the steering damper. good luck!

now if this is the same as i experienced on my range rover, then the answer could be the same..ie front swival pre load insuffient.cure on rangie, remove a shim or two..steering damper also known to cause this..

Good day I am in agreement with the above replace the steering damper and it would not do any harm to have the wheels balanced. A wobble around 80 kph is definitely wheel balacing and once the wobble gets started having a worn damper does nothing to stop the wobble Ernest
