steering shakes

Post by **dwaynes** » Sat Feb 26, 2005 1:42 pm

alright guys heres my problem at around 80k's i get a bad steering shake i have done the usally with bushes and such. The interesting thing was though that i changed front tyres to rear the problem nearly went away as in only a slight shake and i mean very slight but after two weeks of road driving it is back to what it was.

any ideas?

Forgot to add it is a 89 gq patrol.

wheel balance?

its probably still there, but you can't feel it through the steering anymore

will let you know if it fixes it

well i panhards have been done a balance has now been down and it is just about right but still noticable at 80k's

so not sure where to go from here

i have found the best way to do wheel balancing is on car...like from a truck place..u get much truer results.

should sort out ur wheel shakes too.. they are either from panhard bushes or wheel balance..and u done bushes.

as above i just dont think a wheel balance machine at ur tyre shop is accurate enough

If not panhard bushes always come down to tyres for me. I normally get a Bob Jane Silver or Bronze balance,

Unfortunately one heavy off rd trip and they shake and need doing a gain. Sometimes just rotating front to rear is ok until next trip.

thanks guys

I had the bronze balance

Would anyone know where i could borrow a set of rims and tyres for a gq Just so i can rule out the tyres themselves. I currently have 32" BFG M/T.

If anyone could help.

Dwyanes, sorry can't help sorry, but mine has had three different sets of tyres on it in the last 8 months and all with all three, the shakes were very different but always there, have now got second hand 35" procomp muddies and they're the best yet as far as the shakes go! I had all the bushes done in the front end about six months ago and that fixed it for a while, but it has developed a shake again after I went wheelin a couple of weeks ago, so I may have knocked a weight off. It's not too bad so I'm not worried about it, they all (GQ's) seem to do it to some degree.

Mate I had the same prob's with my GU TI and eventually gave up in vain after trying the usual things.

Recently I gave it a 2" spring lift without doing the caster correction bush thing......problem solved

It now has no wobbles or viabrations and feels a hell of a lot lighter on the steering in general.

I don't know if this is any help to you

hi,
I'm new on this forum. (begian visitor)
I'm having the same problem on mine.
I've noticed that the shake is sometimes worse then normale.
How do you check the panhard bush`s?
could a stronger Steering Stabiliser help?

GR,

mine developed a shake after I got it back from the panel beater week before last.......went and give it a hiding on some rocksteps on sunday and when coming home they had all gone again

me thinks you should all drive a bit harder and they will go away :finger:

GR,

Patrolgr welcome

Checking the bushes i was slack and took it on to be done as this was a new car to me and wanted them changed.

The steering dampener i think will only hide the problem and not fixit

just an update guys i have now confirmed with the current tyres that have been balanced that when cold no vibration after about 10-15 minutes of driving vibration starts to come back so in my uneducated think that i might have a sidewall issue with one of my tyres.

my next step is to rotate my spare in to see if i can find a single offending tyre.

To check bushes hold hand around mount and get someone to push vehicle side to side..

You will feel play, same for steering joints.
Stronger steering damper prob wont help but if yours is crook a good one will.

thanks a lot for the information. I will check these as soon as possible.
maybe I should relpace my tires, the are old. I've got them from a friend who wasn't using them for a long time.
Is it nessesary to use a stronger stearing damper with tires 33" x 12.5"?

Gr,

Ha - the Nissan Wobble. Reckon everyone gets it a bit, some worse than others. Since this is a Tech section I'll post a Tech answer. If you have a lift in the car, depending on the size of the lift you may be prone to a head shake after small bumps in the road. Main reason for this is the angle of the drag link and the panhard rod. What happens is that as the car dips with the bump impact, the diff moves sideways in an arc, which, can then set off a steering head shake. This head shake is exaggerated with larger tyres, and worse if they are not 100% balanced.. Really, the only way to fix this is the return the steering geometry to a more standard position. Wizard has a sleeve that you put in your drag link that then allows your track rod to be bolted up under the pitman arm in stead of on top of it like standard. Requires you to drill out the pitman arm hole though and put a step in the hole. End result (I think from memory) is a 73mm drop in the height of your drag link and a significant increase in the ability to control head shake. Only prob then is you've now created bump steer - so you'll need to either raise the panhard rod mount on the diff, or lower the panhard rod mount on the chassis by a similar distance. I have a mate that has done this and runs 37" bias ply tyres on the road.......as a daily driver and has no issues. Also most people with the drop radius arm brackets swear by them as a head shake stopper, haven't got a set my self, but I do have the skank racing arms in the front and it goes alright and no head shake...I can give you more info on this i you want..I've tried shitloads of combos, up to an 8" lift
