Hey guys,

Can't really tell if its always done it and I've just had the stereo on but when I trail of the throttle a little at around 90-100 in 5th I can hear a whine from the tailshaft/diff area.

Can't be sure what it is. Full throttle it goes away, just rolling with no throttle it goes away? Strange, is it possible the gear box is low on oil or something?

They should put dip sticks in gearboxes :D

any help appreciated, cheers!

Yeah that's typical of RB20 gearbox's. Suggest draining the oil and checking for any out-of-the-ordinary metal and if all is OK, filler up with Redline Shockproof Oil and forget about it.

With these box's the noisy parts are the revers idler gear and moreso the input shaft bearing. If you use the Redline Oil and treat em with some respect they can last a VERY long time ( with the noise ).

Hi, thought I would add to this, and perhaps shift perspective.

I have an r32 GTST auto, and have the same issue. I think its not actually to do with the gearbox but rather the diff. It would suprise me if both the manual and auto had the same issue, I think they are made by different manufaturers anyway. Mine is a Jatco 4 speed.

Other reason is, my father in law is a mechanic and he said it was diff noise, so I trust him.

I'm not too worried at the moment as its not too noisy, but, if it gets much worse I might do something about it.

Yes, tell a lie, I believe Rowdy's and mine are the diff. He got his "serviced", which seemed like an expensive fluid change on hindsight, and which did exactly SFA on the noise front.

I rarely hear mine over my exhaust anyway so it doesn't bother me. :rofl:

Change your diff oil , it only takes 2 litres or less. You will want to use Castrol EPX 80-90. Otherwise I would suggest for all of you that you get some Redline Shockproof. It is pretty much the best you can get but is fudgen expensive so I suggest getting in contact with a rep if you can and see if you can buy it through him/her.

Thanks fellas, is diff/gearbox oil changes part of the 100K service? Mine has the timing belt sticker, all new ancillaries belts and a new o2 sensor. Is it safe to assume the gearbox and diff were done too?

How much are we talking for a gearbox and diff oil change. I can't really say I feel like changing them myself.

    • Yes, I know🙄 but the sequential is not in my budget... don't want to reduce power neither, so looks like I'm stuck in the rabbit hole🤣
    • You’ll be very upset when you bust that too not to mention the gearing totally sucks. Don’t do it.
    • Is the panel filter one that is oiled? Have you ever cleaned or touched the AFM?
    • So.... the K&N air box thingo was too big, ended up gifting it to a mate, well, by gifting it he actually supplied food and beer at the pub,  which was nice, as it will not sit on a shelf in the garage for the next 10 years I did trim up some of the existing stuff to neaten it all up and gave it some wrinkle paint, unfortunately it currently has a used and abused mish mash of different types of hose clamps, 4 big fat T bolt type (shit), and a few normal clamps of vairing sizes and brands, but..... only until the 6 constant tension black worm clamps that I ordered from EFI solutions turn up next week Currently the current hose clamps are triggering me hard, LOL Is this the final version, probably not, I really want just 2 silicone pieces, a straight bit of silicone from the filter to the MAF is easy and will happen as soon as I head into Just Jap tomorrow, the problematic part is a 30° silicone bend from the MAF to the TB that I can connect the engine breather from the head, I found that there are bulk head fittings for boat bilge pumps that should work, but until I can get a 30° silicone bend the alloy pipe, and the 11ty thousand hose clamps, are there for the foreseeable future 4 hose clamps are golden, 6 are grudgingly acceptable, the 8 currently holding it all together is just taking the piss    I've also ordered 60 more retaining wall blocks for the front yard, I mis-gonculated the height that was required to get above the base of the Photinia's (red robin's) that are the hedge behind the front fence, currently it is 2 blocks high, and about 1/2 a block short, so going 3 blocks high will be above the base of the red robin's, and allow some room for mulch
