Scraping Noise When I Turn Right

[Aydin]

Gday everyone

I have an r33 gtst skyline that i cant figure out what the hell is going on with. So here we go.

A while back now i took the car out and noticed that when i turn left it makes this incredible scraping noise. Its not there when i am going straight or if i am turning right just when i turn left, soft if i turn slowly and loud as buggery if i turn hard.

We initially thought it was a bearing problem so went out and changed them. $1200 later guess what it wasnt them, because on the exact test drive of the car after i changed the bearings the same noise was there (how did you think i felt).

What seemed to work however was, when i tightened the big centre axle bolt, found in the middle of the rear discs the sound seemed to have stopped, or so i thought. when i turned a little harder wack the sound came back. Now ive spoken to a few people and everyone is telling me something different. these are some of the options

-Hicas problem

-i have tein adjustable coilovers all over so many are saying it is that.

-driveshaft assembly.

I dont have a clue and as you all could imagine after spending 1200 bucks on genuine bearings i dont really want to make another mistake. so if anyone has ever had this problem and has a solution please let me know.

thanks guys.

Ouch.. 1200$ Sorry to hear of your loss..

you sure its not just tyre scrub..what size wheels you running

Check for scrub marks on the back plastic inner guard lining and if it is, dont worry about it..All the cool cars do it

Nah it's def not tyre rub. It's definitely metal on metal.

I don't know who has a better reputation in your area, but if you invest $30 or whatever for a 50pt suspension check thru Jax/Pedders, they'll narrow it down for you (via a drive + physical check on a hoist).

Then you can decide what needs to be done now, and what is superfluous.

Drive shaft? Guesstimate says that whilst driving around a corner on full lock, you get this clicking > grating noise.

Coilovers? Guesstimate says to change back to standard OEM suspension and see immediately if the noise goes away.

just out of curiosity what profile are your front tyres?

[Moodles2]

The rim could be rubbing on the caster arm, take off the wheel and check behind the rim.. and while you are there check for evident rubbing on the suspension .. you could probably ignore this if you are running stock GTS-T rims.

its not the head sheild on the rotor or a rock in it?? mine made a scraping noise once and it was a tiny rock wedged in the heat sheild was only there when i turned strangly enough?

It does sound something like that.

scraping on sway bar? sometimes they move to one side a bit.

yep get it to pedders and up on the hoist. Put the steering on full lock and see what rubs or is close (ie might rub if the car's wieght is on it). Also remove wheels, calipers and discs and see if there are any rocks etc caught as they will cause this noise (I guess you had to do this to replace the wheel bearings though)

fortunately for everyone except you....nissan put excellent quality bearings in the skyline hubs and they almost never fail. even stock bearings on race cars.

my guess is the coilovers pillowball mount that doesnt allow the spring to rotate when turning and producing a clunk clunk sound on slow turns.

put stock suspension back on the front...if the sound goes away...then it's the coilovers that wasnt installed properly.

[chilzzi]

this is happening to me now....coming from the passenger rear.....immediately after installing coilovers all round

only happens when i turn right, so the force is going to the passenger rear. also when going in a straight line, only happens under load from 80km and up..

cant figure it out, there's nothing visually obvious when taking the wheel off.

Happened to me a couple of months ago, only when turning to the right under some load. Couldn't figure out if it was coming from left front or left rear. Was going to book it into a suspension joint but something came up that needed car to do a quick trip. About 100kms short of destination this happened. See attached pic(s).

Got a phone call from my son who was doing the trip to say (briefly) that he knew what the noise was & could I arrange a tow truck 'cos his cell phone was going flat.

Seems my after market upper outer suspension bush bolt/nut combo had slowly worked loose & finally let go under rather hairy circumstances. Fortunately son was not injured, managed to pull the beast up & get off the road before demolition by other road users could occur.

The fix for me has been to fit Cusco upper front camber arms, to replace the damaged item.

Moral : Hearing unexpected noises when rolling/cornering/whatever from outside of vehicle? Get on a hoist asap & go over yer nuts & bolts. Meticulously.

Question I have is; does anyone know where to buy M10 fine thread grade C, 9~10 cone/crown/auto/automotive/Grover/partial torque/uni-torque/elliptical offset/stove type locking nuts in small quantities. I need two, for a sway-bar drop link which needed replacing. (also damaged during incident). I can buy some from China in 300kg lots but really don't need that many lol.

I will post this question again when I figure out the appropriate forum.

Cheers, GW
