Gtr R34 Suspension Knocking Noise

[Fair Dinkum]

Hi I have got a GTR R34 and I have got a knocking sound front/rear suspension, noise sounds just like the shock mounts are loose but I have checked them and they are fine, I have also checked the suspension arm bushes and doesn't seem to be any play there, only get the noise when the road is a little rough, it is not there on the smooth road.

Does anyone have any ideas, I seem to think the ball joints on the outer bearing carrier for the axles have got play in them???? I am going to replace them anyway the front has got a large one on top and a smaller one bottom and the rear has got one on the bottom where can i get these...

Hopefully sort it out giving me the sh....ts. Just had the car of the road for 9 months gettingnew engine,PPG gearbox,brakes now want to sort this.

Cheers Dave.

It must be damn hot working up there in Cairns David!

Can you take your car to get an 'efficient but cheap' 24 or 50 point check with either Pedders or Jax?

Then you can act on the report yourself.

My 1st cousin, also a David is a head mechanic at Cairns Toyota. I believe he's a good diagnostician if required. He knows me as Terry, not Tez

Hope this helps.

let me know how you go with this, i have some interesting noises that ALWAYS disappear whenver i drive near my suspension place, so damn annoying!

mine are 99% from the rear only though. They have also checked once to make sure everything is tight.

Does your happen whilst turning or just going straight over bumpy roads?

how low is your car? have u got coil-overs?

You may be hitting bump stops. I had the same problem in my front suspension and all i had to do was wind the coils up abit.

could just be your springs. I had the same problem in my rally car (mazdaspeed suspension) was only slightly annoying on the road.

Thanks for the reply's from everyone, no its not the coil overs they are Ohlins Flag R the best you can get brand new when I did the engine, only happens when Im going over a potholed road or a rough road, more noticeable at low speed because of less road noise in the car.

Will have to take it in but dont want some dickhead working on it......

How stiff have you got the damper settings?

Hello Bakes,

I have got them set at mid setting, is not coming from the shocks but the rear noise is associated with wheel travel, Im pretty sure it is the ball joint the rear bottom arm is mounted on.

OK, good luck with getting it all sorted. Try and take it to a specialist place that work on GTR's etc. Id avoid the mainstrem places

Think I have found the problem there is excessive play in the Hicas rod ends, the ball joints closest to the rack. I will have to source new ones..
