Isn't NS a 75w90 without sulfurous high-pressure hypoid additive, is it?

Yes, I asked mechanic to look for it, and he said there aren't any that are loose.

Small update. Axle nuts are fine. Noise in neutral afer warmup is there with clutch in and out. No change at all if I depress the clutch. You mean the transmission? It's fine. I will change it tomorrow though and see if the noise changes. Any other ideas?

Well, the noise is not speed, but rpm related. 45-50mhp in 4th and I have lots of it, shift to 5th and it's gone. But I'll have a look at axle nut though. Thanks. You think it might be clutch? I do have the noise in neutral (after 10 minute warm up) with clutch out, will try the other option tomorrow and report back. Thanks

Hi. New here, and need help. Recently got a manual 96 Brighton wagon. I does some sort of scratching/screeching/rattling metallic noise (can't decide which one is closer) at rpms > 2500-3000 in any gear except 5th. May be in 5th as well, but road noise blocks it. No noise until 5-10 minutes of driving, maybe except during start up (1-2 seconds of same noise). Noise does not follow rpms exactly, it is sort of erratic and just becomes louder with rpms. Noise is loudest when I accelerate hard and if I let go of gas, it quiets considerably, but is still there, until rpms drop. My mechanic (who took a ride with me) says its not the engine and not the exaust heat shields. I could probably record the sound and post it here Do I have a crack in exaust somewhere? Any other possibilies? Thanks a lot.

Dan Your link is for manual mirror No auctions for electric, but you can buy it right away for 110. Kinda high. I'd rather search local junkyards.

Like it was said here before, cars with fuel injectors and newer ones with carburator (like less than 20 year old), cut the fuel off when the gas pedal is released completely, and engine RPMs are higher than some threshold. So when you coast down a steep slope in gear and with your foot off the gas, the engine is rotated by your wheels, not by burning fuel. If you put it in neutral, it needs fuel to run. As another argument for coasting in gear, imagine that during way down your engine stalls for some reason (which is more likely in neutral than in gear), and you will end up without power brakes and steering. Scary, huh?
