Shudder In Steering Wheel

[RB25PWR]

I get a small shudder in the steering wheel when I'm going about 110km/hr. The first thing that comes to mind is wheel alignment, but it's had two wheel alignments + balancing done on all four wheels in the past couple of months. (It has had two because the second was an accident buy the mechanic, he thought I asked for it when I did not).

Apart from it being a wheel alignment issue, what could cause this?

Does it shudder when at 110Km/Hr at constant speed, but doesn't occur if accelerating/decelerating through that speed?

If so, check for weakness in the middle of tailshaft perhaps. I'm not sure if the GTS-T has a 2 pce tailshaft like the GT-R though.

Other than that, check engine mounts, front suspension bushes, rack (with leak)...

It's fine at 100km/hr. But when at 110 it shudders... not sure if it stops after 110 as that's the speed limit. I'll try and figure it out though... if I had to guess I'd say the shudder gets worse as I increase past 110

shakes are never a wheel alignment issue, its balancing if anything. If you alignment is out it will not steer straight.

maybe one of your weights has come off/loose ?

I’ve got the same issue on my other R33. Happens around 100-110km/h. I’ve got new tyres, had the wheels balanced and aligned over 5 times so far. Over the many visits back to my local tyre shop they found the wheel nuts were not correct discovering they were not tapered enough so the wheel was able to wobble at high speeds. Changed all of them which made a small difference. Next thing I found was the tie rod ends were stuffed causing play. Replaced them and the shuddering reduced however didn’t fix the issue completely. Found the tension rod bushes had started to perish, however after replacement only a slight improvement was felt. I’m still trying to find the issue. I’m going to swap my front wheels from my other R33 to see if it’s the wheel itself. Perhaps check the parts that I have mentioned for any wear or damage.

tried hubrings to help locate the rim to the hub?

alignment and wheel balance. doesn't take much to knock out a wheel alignment.

check caster bushes. tie-rod ends for replacing and steering bushes. then the rest of the front suspension.

slight buckled rim is quite often the cause of high speed shuddering

Its wheel balance it will cost you about 30 to get both wheels balanced

This^

Good possibility particularly if you have aftermarket wheels as they rarely ever come in exactly the same bore size as the standard Nissan hub size. Suspension place told me that these hub rings/spacers have solved many a wobble problem. Trick is to get a set of vernier calipers and measure your hub size and wheel bore...I'll be doing this soon as I also have a wobble and have had my wheels balanced already.

I had this recently too, turned out to be the wire belts delaminating on one tyre sending it out of round. Had plenty of tread left, was just a fault with the tyre....

wheel bearings?

[RB25PWR]

It's only a really slight shudder @ 110km, I pushed it past 110km recently and the shudder goes away.

[realor]

I had this problem as well, got some hub rings and it went away but now it's back

[Peter89]

find a suspension tuning centre, im sure they ll be able to locate the problem/s.

[666DAN]

my car does the same, in my case it's a warped left rotor

[danMcd]

get your tie rod ends looked at.

for me it was tyres. same deal as you. shaking at around 110kph. faster or slower was fine. when it was time for new front tyres, changed them and the prob disappeared.
