Help with steering!!!

Hi,

I have just done wheel balance on my car on all 4 tyres.

This has been done twice now at two different TyrePower shops.

Resolution after $120 spent: The steering still shakes as soon as I hit 100km/h.

I thought it was my tyres, I don’t know. I don’t remember hitting anything at all.

So I don’t think it would be my mags. Possibly one of the tyres is defective, Front.

Thinking if it is backs, the whole car would shake. So it must be fronts. Either front rubber is defective or the mags are buckled. The guys at TyrePower reckons that’s not the case. I don’t know what else could be the problem. Can you guys offer some sort of assistance even if it is a wheel specialist place.

Thanks heaps.

Al

I was told by a mechanic that the suspension wouldn't affect just a steering, but the whole car. So I am inclined to say wheels. It's only the steering that shakes at early100. Even thought it was my discs. But that would only affect breaking. So the steering would pull to the dirrection of the front disc that is not grinded as much.

That's what I was told. I m getting the all machined and new brakes done aswell.

Some sort of Bendix. Any advice on Bendix while we are on the subject.

Bendix Advance front and rear plus all for machined disc's for $340.

I think that sounds ok. What do you think?

ah yes true but mines only a theory and i need new suspension anywho i find i have a vibration between 85ish - 115ish no probs on strip or track vibration on acceleration deceleration and at steady pace mechanic sed the bushes that are cracked cop the full weight of the front of the vehicle and so may cause it but that theres no danger of s%$t hitting fan sort of thing

How's the wheel alignment?

How's the wheel alignment?

Alignment is fine ,

In that case it would only make the car push left or the opposite on the straight...

Depending on speed. I don't think the alignment would have anything to do with vibrations on steering at particular sped.

If I am wrong please guys explain how that is possible. As the vibrations are on 100 sharp and constant after that. Alignment would affect it on lover speed...

Yes?

If the alignment is out it can only show itself at certain speed ranges, As i have experienced in my Magna. I have a similar problem that at 70 - 90 kms i could feel a shudder but soon as i got over say 95kms it was smooth again. Saying that soon as i got under 70kms it was fine too it was only that range of 70 - 90kms.

So i got a wheel alignment done and it was fixed, i defiantly dont know much about cars or evan physics to explain it. Our problems sounded familiar so i though i would share, i hope i have helped.

when I first got my "line", it would shudder when I reached around 115-120km/hr. The wheels were balanced, yet still that shudder. Didn't do much about it after that as I didn't often go that speed anyway.

When I discovered that the insides of the front tyres were wearing bad (excessive negative camber) I got the alignment checked and camber kit had to be installed as camber was way too much on the negative side. Negative camber will not necessarily give shudder as race cars use huge amounts of -tive camber, depending on track layout. Anyway the shudder is no longer there so I suspect something else in the alignment was out.

Pulling left or right doesn't necessarily have to be a symptom for the alignment to be out.

A failure in a tyre wall could be a possibility for shuddering or other tyre problems.

If you are able, try to swap your front wheels and tyres with one of your mates and take it for a spin. That way you will be able to discount the tyre factor.

If that checks out ok, then you might look at suspension bushes or even shockies.

Hope that helps

when my car got here from japan it had a bad vibration and the compliance workshop got all 4 wheels balanced and aligned however the problem still persisted. He dropped the tailshaft and he 3 uni-joints were worn and not moving freely he sent it off to some place in osborne park and they machined the joints and replaced them and all was fine again.

I had this problem a while ago...

Had 235 rears and 215 fronts, and i always had a vibration at about 110-120ish, went thru like 2 different sets of tyres and it was still there...

... then I got 255 rears, and 235 fronts..... were told the rims were slightly buckled while my tyre guy was doing the balancing, but put them on the car and it was perfect!

It might be your choice of rubber - but if you got two completely different brands both times it wouldn't be that?

Guys I was told by all the tyre places and the mechanics that the suspension would not affect the steering, entire car would be affected. Not just an isolated steering problem. Most likely its the tyres. I have Goodyear, Venturas. $150each, brand new. Found out they have bumps in the circle fronface. When the wheel is rotating you can see the bumps on it. Even with the alignment done to 0.5g an all sides. I think I have crap tyres. It's gona be a Bad year with my GoodYEars. Hope I find something other than that solution.

And guys my steering is critical, it shakes 1 to 2 cm on both sides. at 100-120...not drivable.

Hope someone can recomend a good place.

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
