Drivline Noise

[SHY33]

Hey guys just want a few ideas here, Other nite went driving with a mate anyhow after a while of driving about the car started to get a "werr" noise from the driveline @ about 65 kays and about only under acceleration tho, be it boosting or easy throttle. I a bit worried about this noise now so here my thoughts on it..

1. Diff problem, lsd has gone in it or maybe bearing has picked up some shit and has damage!?

2. Gearbox - As the "werr" happens in 3rd and 4th pretty much it could be mainshaft bearing??? 1/2nd gear is no dramas normal feel no probs but in 3rd and 4th it does and when lightly touching the gear stick you can feel a small vibration to go with the noise..

There is no noise present on free wheel - Netural with clutch both engaged and disengaged and no noise when coasting or down hill only under accel..

What do you guys think? Im gonan drop both oils later today and see if there is any unusual colours. And what oils should i refill with?? apart from redline cause no1 uphear has them!

Car is R33 gtst 95 manual

Cheers all

my r32 does this as well, only when the throttle is cracked a bit. its normal for a rear wheel drive to make a little mechanical noise. WRXs were prime candidates for this. (even though AWD). It will make a noise all the time if somethings wrong. could just be a knackered thrust bearing from clutch dumps?

Seeing it only does it in 3rd n 4th id say it would have to be a gearbox realted noise. Most likely a shaft bearing spun up. It would do it always under acceleration if it was the diff i woulda thought.. I once had 5th gear make that kind of noise sounded like a rally car haha. Best to get a driveline specialist to look at it... Hope that helps ..
