Lock Diff

[PREISS]

I have a R34 with a locked diff.

It's fine when im by myself (sometimes.) locks up nice.

However when I go around a round about. Or even a tightish corner it feels like the whole diff is about to fall out, very strange feeling. Almost like its floating.

If I have more than just me in the car its very annoying and feels unsafe almost.

Howmuch is this prob going to cost to fix ? Im guessing the labour is also going to be alittle pricey ?

is it a mini spool or is it a dodgy weld job?

a mini spool can be taken out if its welded just get another second hand diff center.

locked, 2way diff's etc are pretty scetchy on the streets and pretty scary in the wet. id never have one on a road car thats for sure.

Its not a cheap welded job.

It feels great when its working properly. the car can flick anywhere u want it. Not that I do this, but have tried.

I just feel it could be getting alittle worse with time

what are some estimate costs ?

what's it actually doing? is it giving a few clunk/shoves around tight, slow corners? And what exact type of diff is it?

-edit; Kye's on the money.

Most of the R34 GTT come from the factory with LSD in the later years are you sure its really locked ?. mine does the same thing , sounds wonky and most of these cars dont work well with more then two people in them.to much weight over rear end

check your diff oil, it might need changing ? and make sure you use the right kinda oil in it, or the LSD will fail.

mine makes a heap of racket but checked out ok.

whats the exact diff? 2 way, 1.5 way? or is it a "tight" shimmed LSD thats been shimmed so tight its like a locker?

[PREISS]

yeah its clunking. especially around slow corners.

weird floating feeling sometimes.

kye is on the money yes. Just want to know some prices and estimates.

wonder how long the labour would take.? never touched a diff before.

I have a friend with a workshop I can use any weekend just not sure of how big the job is.

Its locked. it chirps most times.

something is suss tho.

If its performance & behaviour is changing and doesnt feel normal, it wont hurt to get the centre checked out, replace oil etc. i've never had any work done to the diff on my 33 so i'm not sure on what repair bill amounts will be.

I have a 2-way which chirps tight corners, but very tight and very slow turning = clunk clunk clunk. bit more gas = chirps. I'm actually not 100% sure on the health of my diff, so i'm interested on this topic. I've never touched the 33's diff myself; some people say that those characteristics i mentioned are normal, some say they are odd. It performs the exact same as when i bought the car, so i'm not so worried

unless you know what your doing I wouldnt mess with a diff,insides the slightest error and it will fail when you punch it. the measuring is critical and it takes special tools to set them up. to measure runout and tooth patterns.

the gear set will walk out of the case, had a mate rebuild his chevy truck diff with locker, I blew it up one night in the rain.. shot the gear right out of the case and I was barely moving.and that was with skinny tires and less power then a skyline has.

my diff sounds like crap too. but mines under warranty still...lol

I am going to get mine shimmed soon...

been told its $200 odd bucks to get it done

and at the same time they change the diff oil and stuff

hardest thing about shiming a diff is getting it off the car.

there is a good diy on here for it

just going to pay wheelworx to do it mate

$225 just called and everything sorted out for that price

doesnt seem too bad to me

[PREISS]

nice price.

Ill start researching it alittle. have a look at it.

see how it goes and let you know

had a shimmed diff in my gtst - it was quite driveable and locked up nice at slow sharp corners and yet wasn't too clunky. FYI mechanical diffs are clunky and general a little uncomfortable driving on the street. Pulling in and out of car parks etc really binds them up causing them to lock, and then the suspension torsions up and you get the clunking. Kind of the car version of hip dysplasia......

[Mr500]

mate, the problem wont be with your center. that floating feeling will be your rear sub frame moving around on crap rubber mounts that are becoming more and more flogged out with the massive load a locker puts on them. all the rubber bushes in the rear will be suffering.
