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?

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
