R34 Gtt Weird Noise At Low Revs

[SoulScene]

Hey guys,

Lately I've noticed a strange noise/rattle coming from the front of the car at low revs, between 1-2k revs.

I noticed it awhile back on and off, but I just got the clutch replaced and I notice it alot more but it still doesn't do it all the time.

Example, slowing down for speed humps, 2nd gear just sitting around 10-20kms put the foot down to speed up again and the weird rattle noise appears but hit 2-3k revs and gone car sounds normal. Also does it taking off at lights sometimes aswell, does it through all gears if I let the revs drop to much without changing down gears.

Anyone know what it could be?

Cheers

It could be the thrust bearing, in which case it is common. Some Late model cars run plastic carriers for the bearings which quieten the noise, but they can melt when the bearing starts to get hot. Does the noise go away when you put your food on the clutch?

Could be best to get a mech or mate to have a listen, perhaps a local SAU member will put his hand up if you don't know someone?

Likely to be gearbox rattle.

Loaded in any gear at low revs puts excess strain on input/main shaft bearings.

Sorry Scotty, just missed your post.

Mine was very evident before I replaced my clutch.

New throwout bearing with clutch, new gearbox fluid (Nulon smooth shift). Noise quietened down, but still there.

Did you notice a change in the noise with the clutch change?

*edit* More noise with clutch change....

I only noticed it a handful of times before the clutch was replaced, not very often at all either. I got the clutch replaces along with a lightweight flywheel and new trans fluid on Monday and I've noticed it alot since, but it's the same noise as before it was replaced.
