hey guys seam to be having a bit of trouble with my diff, and i am after advice..

what has been happening over the last 6 or so months is the diff seams to be getting very tight/clunky

when turning at a T intersection when i have just taken my foot of the clutch.

now it is starting to do this at higher speeds which it never used to do (40kph thru a roundabout)

can anyone tell me what is actually happening as it is just the stock diff, and it never used to do it.

if i need to look at replacing things, what should i be looking for, jut shimming, rebuilding, aftermarket?

i just want it to stop clunking :P

also my friend mentioned to me that i should stop driving it incase it locks up, will it actually lock up, and if it does

what will happen? in anycase i think it will need to see a mechanic, as its my daily driver.

any advice would go a long way, thanks.

And to answer the questions about the locking

I got a nismo 2 way diff which is always locked. Let's say you are on a bend accelerating gently and you back off the accelerator I feel the back end kick out. Worst thing in your case is that you don't know when it's going to lock. Pretty much just have to worry about understeer and the back end coming out when it locks

if it locks it wont just kick out he will need a lot of speed it will just be even clunkier..

agree with you though doesnt sound like a stock diff cos they just single spin most of the time haha.. get it looked at man best thing to do

Sounds like you may have a decent aftermarket diff and is LONG overdue for an oil change.

I know with my Kaaz diff, i need to change the oil every 10,000-15,000km. As the oil gets older, the diff gets clunkier and noisier.

I have driven a 33 with a welded diff, it's not that bad/dangerous; you just need to keep it in mind on wet roads and take it a little easier.

You guys might be on to something with the aftermarket diff. The car did have after market greddy suspension, i have it booked into the mech next monday to have the drivers side ball joint replaced, hopefully the diff just needs some new oil. Will the mechanic have to take the housing of to have a look, and will there be any special markings or stamps on afyermarket diffs? (so the stock diff would never "clunk" in a tight corner right?)

nothose pictures dont help you need to pull the rear housing of the diff to check what sort of centre you have and it def sounds like a 1.5way 2ways are usually really noisy make sure your mechanic dosnt try to rip you and replace the whole assembly as for driving with a 2 way take extra care in the wet when down changing gears sometimes its like pulling the handbrake on if your doing a lot of street driving maybe stick with a 1.5 way

      Meh. I "see" a typo above, that should have been "sell".

      The clutch pedal has a procedure for adjustment. This can only be done after you are 100% sure the system is absolutely free of air bubbles. You must bleed the clutch master cylinder first, then the "separation pipe" which is the clutch damper line, then the operating cylinder as detailed in the service manual. Also, you must fully depress the clutch pedal between shifts. Just because you can't feel it grabbing does not mean the input shaft is truly decoupled from the crank. At high RPM clutch plates are vibrating and moving around, you need to give it the best possible chance of success. On the BCNR33 Nissan revises these adjustment procedures slightly but not by much: I would be careful with trying to play games with these adjustments. As for the Nismo operating cylinder they say a lot of things. In practice the twin plate clutch needs less movement on the clutch fork to disengage because the whole stackup of the flywheel + friction plates + pressure plate is much taller. Personally if you find that the clutch still disengages too high at the top of the travel I would try the Nismo operating cylinder. Make sure to follow the air bleed procedures.

      Thank you for the links. I’m going to go with the 6pin plug you used. next step is rust treating re painting dash support bar and steering column then the 6pin cradle plug when it arrives in the mail.

      I don't how much the car makes a difference or whether it is just a question of gearbox and clutch. On mine it's fine. Pull type Nismo coppermix twin (standard, not competition) on the 5 speed in my Stagea. OEM slave cylinder. Bite point is a few cm off the very bottom of the pedal. Clutch pedal all the way down to put in gear, and when heading off at the lights, there's a tiny bit of nothing and then it starts biting. And fully engaged before the pedal is all the way released. There's a bit of play at the top where the pedal does nothing anymore. Are you in Australia @ck_chino? If you are set on using a Nismo slave cylinder I have one new-in-box at home. Ordered it together with the clutch but didn't get it fitted. We can work something out if you want it

      I am using a pull nismo coppermix twin in an r34 getrag box, had both the standard slave and  then the nismo one. Adjusted pedal to get bite point how I wanted , it is on the higher side, but would fully disengage past half way down.  I also read that the nismo slave won't work but I had no issues with the stroke, might become one later as clutch wears but 2+ years of happy motoring so far.  Take the above as one input only, specially as my setup is a bit unique in that I am using an S15 clutch master , cefiro clutch pedal, custom braided clutch line. Lots of variables at play.
