Upper ball joints have some play but there wasn't the time to sort these this time around so I'll have the cross my fingers that the work done has sorted this out.......

R32/33/34's don't have upper ball joints. :P

Well they have something on the end of the upper arm. Nissan part # 40160 AR510. Needs to be pressed in and out. Seen it with me own eyes! Must be called something else. Care to enlighten? See diagram in post #2, it's called a third link?

Rubber bushes, inner and outer, on the upper control arm. If they are worn, best to replace then with adjustable (for camber) polurethane bushes, Whiteline, Nolathane, SuperPro etc.

Already got the inner adjustable bushes. The outer one going on what I saw and the diagram don't look like bushes. They look like some sort of ball joint........to me any way.

Let me guess you are running castor rods with a rod ends rather than bushes and the outer upper suspension link bush is lasting next to no time at all?

Dunno really. Those items are 20 years old on my car so yes, could be the castor rods with bearing ends, and yes could be 20 yrs of wear and tear

Just a quick update, I've really only driven at legal hwy speeds but now there is absolutely no feedback anywhere whilst on the brakes. I guess this means that the rotor skimming has done its job, and was likely the cause of the feedback. The question now is what caused the rotors to need skimming. I personally don't think they were warped (just didn't feel like it), so I'm going with the brake supplier theory that the rotors had deposits on them....... As to why that happened, I guess it could be the WBs.....

I think I need some harder driving to see how it all goes once the brakes / front suspension get a harder workout.

hey mate what was the outcome of this? i'm trying to work out a similar problem with my 33 gtr.

im currently doing front shafts and uprights fingers crossed that'll solve my problem but in the process just realised one of my hubs isn't the best

there isn't a dime of play in the hubs its just the bearing on passanger side is bone dry and doesn't turn over too easily/smooth so i may need to look at these also..

not too sure what i'll do with the hubs atm as i need the car for PI on sunday.. (replacing bearings isn't fun :D )

Just saw this post now. Sorry for late reply. It's been a while since I was dealing with all of this but after pretty much making sure all the front brake and suspension components were new I no longer have a problem........Replacing the bearings was a bastard of a job. I didn't do it personally, but I sure paid....

How much does it cost you to get someone to press the new bearings in?

      A 1.5 way is a 2 way. It is just a 2 way with a less aggressive ramp on overrun.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      The ABS and/or TCS being missing/broken will not cause the engine to misbehave. It just casues CEL to come on and annoy you. The CEL is useless if it is always on, so you have to do the things you have to do to get rid of it, so it can be useful. Being a Stag ECU, then yes, it will not expect TCS to be present. But it will expect ABS to be present and working. You will need to either make the ABS CU talk to the ECU (don't ask me what that will take on an NA R34), and make sure the hardware is working....or, you just need to blank it out in Nistune. Do not persist with the stock ECU. You will just have problems. Gte it Nistuned. Start from there. DO YOU HAVE A BOOST SENSOR? The ECU's boost sensor that it. It is connected to the loom at the rear of the coil cover. Usually rides on the firewall on an R34, but is usually bolted down to a bracket along with all the other crap at the back of the coil cover when a Neo is dropped into another car. If you do not have it, the ECU will shit the bed. So, do you have one?

      So sadly the fuel pump etc was not it. The pump and filter is new and it is still cutting around 4000 rpm. A read something about ABS/TCS (engine is from stagea and ECU too so no TCS) and i dont know for 100% that my car has ABS. It has ABS "cube" in engine bay but i dont think it works(or at least from my braking experience). Can be something like that?  I will be driving the car next week to Nistune tuner to properly see what is wrong...

      the Tomei LSD fluid with lsd kit. frustrated that it was shaking the car to crap and affecting everything else negatively, I pulled the diff last night, and removed the lsd carrier, could not find anything wrong, however it seem to be 100 locked up acceleration, and deacceleration, wondering if they sent me a 2 way not a 1.5??  either way I installed the stock open carrier back in place. test drove everything smooth as butter again. no shake, shutter, random, what felt like clutch slip and grab or drive shaft play, etc. something differently wrong in side the lsd. I might bother taking it apart (if possible) to figure out what's going on inside this carrier, as bought too long ago to return.  only draw back is its back to a one wheel wonder.
