Hi guys....

The steering wheel doesnt seem straight when im driving straight ahead on a dead flat, straight road.

I recently had new tyres fitted thinking that that couldve been the problem. Had balance and alignment. Problem is still there on some roads. Falken specialist said it's cos the car is lowered and it tracks the camber of the road.

Fair enough but why is it when after ive been driving for a few minutes and i build up speed on a main road that i can almost see the steering wheel turning in my hands (always the same direction - down to the left) but the car still steers a steady straight course?

It's so disconcerting as you're building speed to have to readjust your driving style every few mins to compensate for the changes in steering wheel movement.

I was reading in HPI that there's a thing on GTRs called a steering wheel position sensor which can be zeroed.... could this be the prob on my GTSt?

What where the wheel alignment specs when you had it checked?

I will bet it has less caster on the left hand front than the right, common problem. Either that or they didn't check the rear wheel alignment. Either way the specs will tell the story.

Dunno about the specs but i made sure they did a rear wheel alignment aswell..... so more than likely castor...

Im getting a servie tomorrow so ill make sure it gets checked

Tell me something though, it's highly unlikely that the camber of the road would cause such major steering wheel alignment issues eh???

Just like a dyno is for an engine, I never leave the workshop without a printout of the wheel alignment. If you have a lack of caster on the left, then the road camber just makes it worse, it's like 1 + 1 = 3. If there is a left front camber problem as well (even a slight one) then 1 + 1 + 1 = 5. And some roads have way more camber than others...........

Hope that helps :)

HSVKLR - is what u are experiencing like this - say u start off driving slowly, steering wheel is straight. then as u build up ur speed, you find that you have to turn the steering wheel to one side, but the car is still going straight?

two things -

1) HICAS may be leaking on R32 (happened once to me, locked it and problem went away)

2) problem came back later on, more severe. turned out that one of the steering rack rubber bushes thingy was worn out and allowing unwanted movement - not sure what they're called, it was this rubber ring like thing that are on both sides of the steering rack. ordered replacements from Nissan, got it the next day and problem gone.

hope that may help

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
