BigSlick Posted October 29, 2012 Share Posted October 29, 2012 Hi, Ive noticed a slight judder when moving forward slowly on full lock either right or left. Doesnt happen in reverse. I thought it was the wheels skipping on surfance as my car park is a little stoney but I just noticed it coming home from work out of the car park. Its very slight but its annoying... Car is just OOW from 19th September and the car came with 3 month warranty from the dealer in Essex. So anyone have any ideas or should I just pop it into Nissan and ring the dealer I bought it from? Reason im asking incase its something simple/small ive missed or can fix myself. As I said its quite new (just OOW from Nissan) and just gone over 13k miles (12,300 roughly at time of purchase) Thanks Bri Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted October 29, 2012 Share Posted October 29, 2012 Check your PAS fluid. Alex Quote Link to comment Share on other sites More sharing options...

steve-r Posted October 30, 2012 Share Posted October 30, 2012 It funny you should mention this, as I found mine does the same, I have checked the fluid and its on about Hot Min. ( I can only assume maybe the fluid isn't up to temp if it does actually get to a operating temp ) Quote Link to comment Share on other sites More sharing options...
Ebized Posted October 30, 2012 Share Posted October 30, 2012 Its normal on the 370's in colder wweather - particularly if you are using the Brigestones that have relatively hard sidewalls. Unless it is still doing it when the tyres have warmed up, then it needs checking. When turning the car on full lock from cold will make it feel as thow the tyres are slipping sideways across the surface (like a judder). To do with the geometry at the front of the 370's that is different from the 350's. When I first got my 370 (after two 350's) I was a bit taken aback but you soon forget about and if you change to softer sidewall tyres (as I have done) it all but elimates it. . 1 Quote Link to comment Share on other sites More sharing options...

Brilliant news Colin thanks for info. That takes the worry away now Oh yes, and im running Bridgestones Quote Link to comment Share on other sites More sharing options...
ScottyZ Posted October 30, 2012 Share Posted October 30, 2012 I have the same issues - it's the colder weather. Quote Link to comment Share on other sites More sharing options...
BigSlick Posted October 30, 2012 Author Share Posted October 30, 2012 Ahh great... Puts my mind at ease. Thanks for the info. I check the PAS fluid and its above Min Cold (it was cold) so thats fine. Thanks for the info guys. Bri Quote Link to comment Share on other sites More sharing options...
Hutch Posted December 12, 2012 Share Posted December 12, 2012 (edited) I bought my 370z GT Auto last Saturday and noticed it judders in when I go forward or if it’s in reverse in the morning when I leave for work and again when I leave work. Make sense if it does it in the cold weather and I’m running Bridgestone's. I have 2 years left on the warranty, should I take it back to the dealer?

Ekona Posted December 12, 2012 Share Posted December 12, 2012 It's due to the Ackermann principle, see Colin's explanation above. :smile: Not a problem, it's just how cars are designed these days. Quote Link to comment Share on other sites More sharing options...
glrnet Posted December 12, 2012 Share Posted December 12, 2012 Dan, is there an Ekonaman principle? :smile: Awaits flaming :wink: Quote Link to comment Share on other sites More sharing options...

N9JAH Posted June 4, 2013 Share Posted June 4, 2013 What tyre options should I consider to try an all but elimate this? I was saving for some Mich SS but I know Mich rubber is hard wearing. Quote Link to comment Share on other sites More sharing options...

LordSQra Posted Friday at 11:16 Share Posted Friday at 11:16 Sorry to revive an old thread, but I’m experiencing a similar issue with my 370Z Nismo. My tires are skipping badly, and I hear a metallic clunk when the car judders. The clunk seems to come from the front and it’s especially noticeable and embarrassing when leaving a car park. I’ve read about the Ackermann effect and cold tires, and people say it’s normal and unavoidable, but it feels worse lately. My PAS fluid is fine, and I’m currently running Pirelli P Zero tires, which have hard sidewalls. I don’t recall noticing this issue with my previous tires (Michelin PS4S or Dunlops) in the past five years of owning the car, so I’m considering switching to softer tires to see if that helps. I also notice some noise on full lock when driving up or down the spiral ramp of a multi-story car park, even with warm tires. My tire pressure is set to 35 PSI front and back. Could alignment help reduce the skipping? Lastly, after driving a rental car for a week, I noticed my steering felt stiff when I got back to the 370Z, but it seemed fine after a few days. Maybe it’s just the nature of the car. If I ever decide to sell the car, this could put off potential buyers, and I don’t think they would accept “it’s normal for this car and it's just physics ” as an argument—I know I wouldn’t. Looks like I’ll have to sell it in the warm summer, lol. I’ll try to record a video and add it here later. I’ll probably take the car to a garage to have it investigated, but I was wondering if anyone here has managed to fix this. As I mentioned, I didn’t have this issue before, so it doesn’t seem normal to me. Any thoughts or suggestions would be greatly appreciated! Thanks Quote Link to comment Share on other sites More sharing options...
Keith D Posted Friday at 12:22 Share Posted Friday at 12:22 (edited) PAS problems are often the fluid condition or drive belt. I'd check both. Is the geometry & ride height stock? Edited Friday at 17:12 by Keith D Quote Link to comment Share on other sites More sharing options...

Thanks, I’ll get the belt checked, and yes, it’s all stock. I’ve just got to work now, and after driving for 20 minutes, I was turning on full lock, and it seems fine—it’s only an issue when the tyres are cold. As I said, it wasn’t a problem before, so it can’t be physics 🙂 . I’ll try softer tyres and hopefully, that’ll sort it. 1 Quote Link to comment Share on other sites More sharing options...
Keith D Posted Saturday at 09:06 Share Posted Saturday at 09:06 (edited) Dr Google suggests the original fit was Yokohama Advan, which is a softer sidewall tyre. Edited Saturday at 09:13 by Keith D 1 Quote Link to comment Share on other sites More sharing options...
LordSQra Posted Saturday at 10:43 Share Posted Saturday at 10:43 My car originally came with Dunlops, but I later switched to Michelin Pilot Sport 4S (PS4S). Currently, I have Pirelli P Zeros on both the front and rear, but the front tires need replacing. I’m considering going back to Dunlops or Michelins, or maybe trying the Goodyear Eagle F1 Asymmetric since I read they are softer. Yokohama Advan tires also seem to have good reviews and are reportedly softer as well. Thanks ! 1 Quote Link to comment Share on other sites More sharing options...
