Default Differential clunking....

The LSD in my diff works great... but when i do low speed turns, for example pulling into a parking spot with the clutch pushed in,
a clunking noise comes from the rear end, im pretty sure its the differential because i have no idea what else it could be.

has anyone had this problem before?

its not a click, its a clunk lol

Thanks for your help,
Nathan

I have a similar sound when i engage the clutch pedal. It sounds like a deep clunk, I took it to Honda when i first got the car and they said the clutch master cylinder was leaking, so replaced that but the sound did not go away.

I believe I've also read on the forums of other people with similar problem/sound, their solution was re-torquing the axle nut. It seems you can do this by simply removing the center cap, un-staking and removing the axle nut, oiling (not greasing, not sure why) the threads and contact surface of nut, then re-torquing to 220ft/lbs.... use a 36mm axle nut socket.

I also need to do this myself, hopefully it work.

On the axle nut retorque, the shop manual says to put motor oil on the mating face of the nut, not on the threads.

Ive already done the whole re-torque the axle nut fix, I had that "clicking" noise, but this is a clunk while the clutch pedal is pushed in and while the car is making a sharp turn. If I am cruising down the road and push the clutch in, it doesnt make a noise, but when i do low speed turns it makes it.

Nothing is loose. You have a sticky LSD unit. When making low speed parking lot type turns with the clutch pedal in and coasting, you will get a consistent thunk-thunk-thunk.

It happens, and it wont hurt anything.

More proof that dealers are 100% incompetent.

I changed the diff fluid today and found metal shavings on the drain bolt plug... should i go ahead and get a new diff or should i just keep using this one?
