hey guys..

over the weekend i changed by break fluid. i bleed all 4 breaks and the clutch. the front calipers were removed so i could push back the fluid in the pistons to get it all out. everything was re installed no worries.

went to drive to work this morning the steering wheel seemed to have quite a bad shutter in it.

you would only have to be going 40-50km's whilst turning and you could feel the shutter.

it wont shutter going in a straight line, though said i hit 110 and it just started shuttering like crazy all the way back down to 80..??

it will only shutter going around corners where you have to move the steering wheel a bit. bumps seem to encourage the vibrations to.

its almost like it feels like both wheels are fighting one another. if i turn to the right lets say and it starts to shutter it feels like the wheel wants to turn its self left like im fighting it and the more you fight the more shutter you get. its weird. there is quite a bit of force behind it to..

kind of feels like abs shutter when im cornering but im not under breaks or anything.. could the abs do this..?

iv had a mechanic go over the car this morning and he can see anything loose or slack anywhere. he said the front end is quite tight actually. he said it could be wheel balance or alignment so iv taken the car to get that done, thought i dont see how this will help. the mechanic was pulling and pushing on things but couldnt find anything wrong.

one thing i did do was jack the front of the car from the front cross member under the motor. i know the steering actuator is mounted up there so i might of bent something.. i showed and asked the mechanic and he seems to thing that wouldn't of done anything..?

its usually pretty smooth to drive and has never had shutter to it whats so ever. could it be anything to do with the abs.. or could have i stuffed the steering actuator..? it moves quite free still as do the rotors in the caliper. nothing else on the car was touched and no wheels were rotated..

dose anyone have any suggestions..? its a r34 gt manual.. rwd n/a

iv just been reading about this HICAS thing.. i still dont fully understand how it works or how to lock it out. would by r34 have HICAS and could it be this causing my problem..?

im not trying to push the car when the wheel starts shuttering, it will do it even at 60km

ok so i got the car back from getting the wheel balance and alignment done. the boys in the shop said they cant find anything wrong or know why the steering is shuttering.

drove it home and its still shuttering. change of road surface will cause it to start shuttering. going left and right on the steering wheel fast but small amount of movement will also cause the shutter to start up. accelerating while its shuttering dosent change much, if anything it gets worse. once it starts it will get worse for a bit then dies off its self. it happens quite frequent and usually lasts for a few seconds. there was one time it started up as i was cornering and i kept accelerating a bit causing the shutter to stay for about 20 seconds.

i got home and started playing with the steering. i reversed up the road at idle full locking the steering wheel left and right quite fast. sometimes it would get a point where the steering goes really hard all of a sudden.then some times it would relax again and get easy through the turn but other times it caused the hole steering to go stiff (as if the pump wasnt running (motor of)) and would stay like this untill you stopped moving the wheel for a second then it would be ok again.. i found that quite weird.

when going slow i can hear a squeak rattle sound when going over a bump. now when i hear the noise the shutter happens. when driving and the shutter happens you can sort of hear something beating the same as the shutter somewhere in the car.

going over a small but pointy speed hump the other day in it i noticed one of the shockers had a loud dry squeak noise come from it..

could the shuttering be something to do with the power steering actuator or system where valves or something arnt functioning like they should.? or getting cavitation in the system somewhere from a leak or something.

im just very concerned because the car never usto do this and the problem is in the steering. i have to drive the car 150km a day to get to work and i know what its like to have a front wheel collapse underneath the car (taking the break line with it and breaking it) after just come round a corner at 70km lol. thanks pedders for the dodgy repairs.. cant even get "the right bolt" right....

dose anyone have any ideas..?

Im no expert but if you didn't have issues before taking the front wheels/calipers off to bleed the brakes i'd start there. I'd check that the pads are seated properly and check for gouges/rough spots on the rotors. Work back from where you started and see what you find.

Good luck

thanks nauto34. iv already done that, was the first thing i did at 7.30 in the morning when i got back home haha. i also had both mechanics look over the breaks and they couldnt see anything wrong.

iv bought a bottle of nulon power steering fluid with stop leak formula to wack in the power steering system. maybe the valves and seals other things in the system need some freeing up. was going to fill the system with this stuff for a few weeks then put normal fluid back in it.

for all i know its never been changed..?

is there a way to bleed the system.? if so how

how do you dump all of the existing fluid from the system.?

Leaked brake fluid on pads? Now it empregnated

In them, or fluid or grease on rotors now hot spotted , backside prob

Shocks creaking are most likely dead or too low/bent

Power steering

Use lucas power steering oil or trans fluid ,not nulon junk !! The lucas will be drastic difference in smoothness and idle vibrations, find it at supercheap but beware the bottle is in usa sizes so trans size for 19 bucks if you flush it

Small size if its really bad shape plus trans oil

Redline trans can be used as well but its expensive ( smells like hell too lol) mine flushed with outboard cooler used 2 liters roughly ( about 80 bucks worth !!)

when you do power steering it has to be done front jacked up and on stands , free drop the wheels so they can be moved free by hand

Flush, fill, move wheels lock to lock a few times by hand no engine running!!

once your happy and fluid full again

start the engine , you might hear a loud squeal if the pump was low but only last a split second, turn locks to lock a few more times you will see the wheels freaking out and short shutter violently until all air is out , you will also notice any loose parts rattling on the suspension when that happens

If the pump isnt leaking that should sort it

Unless brake related

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
