slimjim Posted January 5, 2012 Share Posted January 5, 2012 Been out in the car today for the first time in a few weeks. Pulled out of the road and was tootling a long, pulled round a right hand-er (quite tight) and the steering wheel juddered loads. Found a closed car park, drove around a bit and it did the same on a left turn. But only at half lock (no more) and at a semi decent speed (30ish?) Anyone know what this could be? Straight line drives fine, normal lefts and rights (even large roundabouts) absolutely fine. But tight turns and small roundabouts, judders pretty bad Could it be the Power steering fluid/pump?

ZMANALEX Posted January 5, 2012 Share Posted January 5, 2012 PAS issue more than likely. Check the fluid level for starters. Alex. Quote Link to comment Share on other sites More sharing options...

Cheer Al.... can't understand why it does it on half and not on full. Will look at the PAS fluid ASAP. Quote Link to comment Share on other sites More sharing options...
Lincolnbaggie Posted January 5, 2012 Share Posted January 5, 2012 Had the same problem on mine - turns out it was the power steering pump had gone. Most likely cause, however, is air in the system, so try bleeding it properly to start with (it can take a while to get all the air out). There is a thread about it somewhere - have a search.

Lincolnbaggie Posted January 5, 2012 Share Posted January 5, 2012 Correct bleeding technique is listed below: 1. Stop the engine, and then turn the steering wheel fully to right and left several times. NOTE: While air bleeding the Hydraulic System, frequently check the reservoir tank, add additional fluid up to the MAX level, if necessary. 2. Run engine at idle speed, hold steering wheel at each “lock†position for about three seconds. 3. Repeat the 2nd procedure several times at about three seconds intervals. CAUTION: Do not hold steering wheel in the locked position more than 10 seconds. (It is the possibility that oil pump may be damaged.) 4. Check generation of air bubbles and cloud in the fluid. 5. If the air bubbles and the cloud don't fade, stop the engine, leave air bleeding behind until the air bubbles and the cloud fade. Perform the 2nd and the 3rd procedures again. 6. Stop the engine, check fluid level. Quote Link to comment Share on other sites More sharing options...
Wasso Posted January 5, 2012 Share Posted January 5, 2012 I had the same vibration quite some time ago. Found the PAS fluid was near on low and filled it to max. Vibration then went away Quote Link to comment Share on other sites More sharing options...
slimjim Posted January 6, 2012 Author Share Posted January 6, 2012 Just checked it now it is cold... it is on "Min Cold" So I guess I should top it up to between Min cold and Max cold. Alex, which bottle should I use? I have a load of Nissan Grey bottles from you. Which one should I use? Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted January 6, 2012 Share Posted January 6, 2012 Take it up to max cold, if cold, with KE908-99931 Check the numbers on the bottles very carefully as they are all very similar. Alex.
