Wierd "clunk" In The Diff?

[QRI05E]

Hey fellas, lately i have noticed i get a slight intermittent 'clunk' in the rear end of my car when taking my foot off the throttle when the revs are constant... I have NEVER dumped the clutch or done burnouts... i do occasionally take off bit hard off the lights for a run but that’s bout all... Could something be loose? What should I look out for? Is my Diff/tailshaft on the way?

Another question... what is the difference between 1 way, 1.5 way and 2 way LSD diffs?

Regards,

Sarkis

hey dude.

(ur not rashal sarkis that used to go the st pauls are ya?)

anyways.. i got the same issue. im guessing my diff is stuffed, cos i tried to be cool my the guys on the movies and did alot of drifting.

does anyone know how much it costs to fix this problem? (ie how much for a new diff??)

[QRI05E]

Nup sorry dude... wrong Sarkis

I don't think my diff is stuffed, its just feels more like a loose tailshaft...

[adrianlee]

well i hope thats what mine is too. do you know how much this costs to fix? anyone?

take it to a suspension/diff place and see what it is

[4DoorWhore]

check U-joints - get under the car and turn the drive shaft back and forth by hand check for play. there should be no side to side (i mean like left to right or up and down) there should be a little turn-play but not much...

check diff mounts and subframe mounts - those are the rubber mounts that are inbetween the car and the sub-frame/diff.

if its happening during deccel or accel its prolly the diff mount..

and last but not least check YOUR LUGNUTS! seriously the come loose sometimes, happened to me i felt stupid haha...

good luck...

Anyone correct me if I'm wrong but:

1-Way: Only locks up under acceleration

2-Way: Locks up equally on acceleration and decceleration.

1.5 way: Locks up harder under accel than decell.

yeah pretty much thats it zappn. its all in this months hot fours. they got an article on diffs.

About ur clunk noise.... i had it in my 200sx sometimes turned out 2 of the bolts on the rear subframe where about half a turn loose. tightened them up and it stopped. mechanic or suspension shop is the place to go. cheers paul

mine turned out to be both rear wheel nuts loose after a service!

Had me worried!

[Endless604]

does it only start to happen after your car is up to temp? are you sure it's not exhaust backfire from when you lift off throttle?

this may seem super obvious

but sometimes people don't realise

I have the same problem in my r33 so if someone finds out exactly what it is then let us know! seems to be a common problem!
