Steering Shake.

[Ben-e-boy]

Yep done the castor correction when the car was lifted, still wobbled, its not a Band-Aid fix its the only fix nothings else works read this post in its entirety Mrs h had done this she practically had a front end rebuilt inc. new standard springs its a design fault from Nissan go on YouTube and do a search your trying to tell me all these cars need their castor corrected and with over 2000 hits to this post there is some reason why they are reading it, how many of these people have the wobbles 100 200 even, with castor issues I don't think so

Re read my post.... I said THE FIRST THING THAT SHOULD BE CHECKED IS CASTOR.

I have read this thread. I asked what the castor was set at... no reply, so it to me it hasnt been checked and documented

Again in my other post I said that there very small working tolerance.

How do you know it was correct in the first place? No use throwing castor correction in if you dont know what it was. How can it be corrected of you dont know what to correct? Do you think that the radius arm mounts both chassis and axle are 100% correct to exacting tolerances every time on the 100's of thousands of patrols ever built on a large scale production line? No way... patrols aren't that well built.

The fact is, that the wobbles are a direct byproduct of castor angle/king pinin inclination, a reduction in castor angle reduces the tyres contact patch with the ground, therefor reducing the stability of the steering system.

Thats why I stand by my "bandaid fix" comment as removing shims does not change the incination of the king pin.

While we are here. I too have the wobbles, I bought them home last week end from my trip to landcruiser park. It happens under breaking. Easy fix.
I have elongated the front bolt hole on the radius arm axle mount, every time I break, the front diff rotates forward, reducing my castor angle, thus reducing the size of tyre's contact patch with the ground and stability in my steering....Bam......wobbles. When i get some lathe time I'll turn some washers from a chunk of 4140 I have, set the castor close to 3 degrees and drive out without the wobbles. Its not the first time I have had the wobbles and it wont be the last

I'm not interested in watching a video on youtube on bandaid fixes. I would rather learn about suspension and steering engineering so I have an understanding as to why. But each to their own I guess
