Rear Camber Arms, Tyre Wear

hi guys... ok bear with me while i run this through..

ive had an overly annoying 'squeek' coming from somewhere in the rear for the past 3-4 months, its comes and goes, but sound at times my car sounds like a rickety old trailer at times.... its embarrasing the amount of looks it get...

i took the car to a large suspension related business (not mentioning the name) 2 weeks ago to finally fix the problem, and they said its to do with the adjustable rear camber arms that are fitted to the car, something about them not being fitted correctly by the previous owner... they fixed the problem, for a week....

i just jumped under the car to have another look myself and it appears all they did was smear the arm in some sort of lubricating grease to stop the squeek.. looks super sh!thouse...

im about to get new tyres, as the insides are very worn.. but i want to get the squeek and the obvious camber problem (see tyre pic) fixed before i get new tyres as i want them to last...

my 2 questions are:

Should (when the car is on the jack) the wheel move around at the carmber arm joint (pictured)? it has a couple of mm lateral movement when i push/pull the wheel, and is this related to the god awful noise?

jsut want to get it sorted, as i said, so i get rid of the noise and dont wear out my new tyres too fast.

i want to take the car somewhere with a good rep in melbourne to fix the prob once and for all, who can u recommend?

cheers

james

The wear pattern is more reminiscent of a toe-out problem than a camber problem.

The squeak is totally unrelated to the tyre wear. I agree, they did a pretty crappy job on the bush - it really needs to be disassembled and re-greased. It looks like a rose-jointed setup - could have worn a bit to produce the slackness you describe.

GT-R rims are about a +20 offset, IIRC, so the rim is sitting out 20 mm further than a comparable GTSt rim. That will load the bearings abnormally and may also contribute to the tyre wear. And may be putting extra pressure on the camber joint.

There should be virtually nothing to very very small amount of play in that camber adjustment. You might want to check its not the rose joint(spherical bearing), if the previous owner put them on and bought them second hand or has used the car extensively for drifting/circuit racing even with new ones they are probably worn and need replacing and that could be the noise and cause of the excessive tyre wear.

SK is right about rear camber arms. I got them because I didn't mind the downsides :)

Silicone grease is your friend - remove their muck (looks like it was done by someone who doesn't know where the lube is meant to go) and spray the rose joint. If it's worn as blind elk said that won't help, then remove them :blink: Otherwise I'd keep them till they stop working..

      Squeaking clutch/throw out bearing

      By jayden_l33 · Posted

      I am getting the same issue. Did you resolve it? I just got it after installing my new super coppermix and literally the same issue, new fork, new 18mm carrier, release bearing that came with the kit and replicated the exact same sound.

      If you like - I have the STL files so I can email em. There's a couple of gotchas (i.e the holes are not threaded so you might need/will need) to utilize some M3 melt-in threads for some of the points. However if you want to be super accurate, and are willing to remove your calipers and your SHOCKS it's a really good tool. You also might need to scale the part that measures the tyre width a bit wider. It defaults to a 7.5in tyre and I mean who is running that. Luckily with the magic of CAD this is very easy to rescale.

      jeebus. glad you weren't under it while performing the stunt. Also thanks for the link to the wheel measurer, exactly what I needed

      Who has a Infiniti Q60, Q50 (V37)?

      In the older stuff there were very significant differences 2wd to 4wd, for example Stagea had strut front end for 2wd and double wishbone for 4wd so it was not minor to swap. From poking around the 2wd v37, it *looks* like it might be more possible; some of the parts specifically have "2wd" stamped on them which suggests the platforms are more similar. You'd still want to start with a 4wd half cut to swap stuff from though. I'd suggest if you don't have a tune on the ECU you don't really need one on the trans either. Throttle mapping is in the ECU side (and you can always use a Roar Pedal if you want the throttle to actually respond to your foot), and really if you are happy with the stock power you probably accept the stock trans behaviour too....its all made to be "sporty" not racey.

      So, updates. I have not washed the car since it came back from Tassie. I've driven it around a bit but not got around to actually sorting it out. I DID raise it because I cracked the rear bar leaving a hotel which was very distressing. Interestingly, the car drives more compliant now that it's raised a fair bit (5mm front, 15mm rear). Also noticed that my FR height was 10mm lower than FL. So that's now sorted out, too. I also bought this and had it printed: https://www.etsy.com/au/listing/1576422240/wheel-and-tire-fitment-tool-universal?ref=shop_home_feat_1&dd=1&logging_key=08f604d9fa4cc383550ba985e6ac85cd5cac7fbb%3A1576422240 Now, if I was smart I would have taken my brake calipers off to actually use this correctly but it was evident enough to me that in the region where the caliper was... there was nothing to hit suspension/guard/arm wise. So I'm going with "it'll be fine" after using the tool to hopefully very precisely measure the wheel clearance. Also while doing this, I had the very VERY bad idea of jacking one of the wheels/suspension arms up while the rest of the car was on jack stands. I did this to see how the arm would travel. This all was well and good until the car slid off the stands and went through a fence. So don't do that. Incredibly nobody was hurt and there was only minor damage to the rear bumper as the car didn't have far to slide, and had 3-4 wheels on it. The only damage turned out to be the fence itself which was easy to fix, and a little bit of damage to the fibreglass rear bumper trim. I had already planned to try a touch up paint kit to fix the time I drove into my garage door to see if it'd help in the interim before I get it fixed properly. I used the Dr Colorchip kit after looking online and seeing everyone talking about it. Yes it's made for chips and not huge broken missing pieces and I'll be 500% recommending it for stone chips after using it for stupid things like me. This took about ... 10 minutes and looking at the half assed photo the 30 second job I did on the bumper corner was almost perfect just by using the tiny little brush and painting it in. The sealact stuff to remove over-painting is really useful, so if/when I do it again I'll likely slather the touch up paint well over it and then clean it up with the cleaning solution. The wheels should arrive in a couple of weeks. I am still kinda confident after doing a stupid amount of measuring (and borrowing a set of 18x10.5+15) that they will not fit because I overlooked something, somehow and flew too close to the sun. ALSO R34 GTR guard liners do not fit on a GTT. I bought the undertray brake duct guides and had the wonderful problem of them not fitting my intake, my oil cooler and the liners themselves were even worse. Attempting to fit them won't work in general - You would have to cut them up as another poster mentioned as the bodywork is different on the GTT. At least I can try to resell them. So instead of cutting those up, I cut up my old already-cut-up GTT liners and extended them by using some PP plastic and drilling some 8mm holes for some nissan clips for the 'extra' bit. Because I was happy to cut them I was able to mount them pretty damn forward so I now have some semblance of guard liners, and the brake vents seal the bumper from the bottom. It sort-of-looks like this, to give some idea - If you look at the GTR and then the GTT this is when I realised that I needed to seriously measure as the inside of the rim area is entirely, entirely, entirely different and could not take any internet measurements for granted.
