What Will Happen When It Locks

[omy-33]

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

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.

Are you sure it's just the stock diff? A stock diff will never lock on a corner and doesn't get tighter with age. It gets looser.

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?)

[omy-33]

i took some snaps this arvo i dont know if it will help.

since we on the topic of diffs.

Anyone got advice with driving with a 2 way diff on the street? thinking of getting one in the future and i like to do alot of research before hand!

and i'm trying to get into drift hence the 2 way

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

[omy-33]

well, new oil is in the diff now.

its still locking on tight corners, more so when my clutch is still a little engauged.

any ideas of what it could be? im serious when i say this never used to happen with it.
