Gear Box Noises On Skylines

Hi guys,

i just fitted a new H/D clutch and changed my gearbox oil (Redline). However, i noticed that my gearbox sounds pretty loud. It's the grinding sound that i know you normally hear but i feel that mine is exceptionally loud!

The clutch sounds loud as well when i release the clutch to neutral, only when i 'clutch in' then the sound goes away.

Is anyone going through the same situation as i am or it's pretty much normal or i can do something to decrease the noise besides increasing the volume of my stereo?

was it just a heavy clutch or a twin plate. if it is a twin plate, then they always make noise. if it was just a heavy single then the noise is most likely a noisey input bearing. i have the sound noise and thats what i got it diagnosed as.

What type of noise is it.. rumbling?.. whining??..

Sounds like it's probably on the input shaft bearing if it's when clutch is out in neutral..

Mines currently got a similar issue, however 20x worse.. sounds like i've got straight cut gears..

Yes links it's the whining noise. Sometimes u can hear it when u release the throttle. How bad is yours?

Is there any way at all to fix it?

No mate you'll be allright, I have the same problem and most of the people I know it is a bit annoying but you get use to it i suppose.

It can go for years apparently until it finally dies on you, and if you are smart you would have saved some money and get an RB25 second hand gearbox put in. apparently they are tougher than RB20's.

Sorry for the late reply..

Mine is really loud on acceleration/deceleration.. so whenever you put load on it really..

You could look at recoing the gearbox.. no point replacing an input shaft bearing and that's it as they need to remove the front bell housing off..

$400 labour to pull it down..

$300 labour to reco gearbox

+ parts..

2nd hand R33 gearbox - try $1400 in unknown state.. so see how annoying it is..

Than again.. with these things you never know what it could be.. maybe goto a gearbox specialist and get a recommendation..

With the clutch in.. e.g. foot on pedal.. and free revving it - can you hear it??..

Also - in 1st/2nd.. rolling down a hill with the clutch in.. can you hear it??..

I don't drive an r 32, i've got a 34 :) but i don't think a 33 gear box can fit into a 34?

Well.. I would.. but my one got replaced about 300kms ago..

I've got a rattling/squeaking thrust bearing as well.. but it appears to be going away as it maybe grooves in or something.. not sure what the hell is up..

does the rattling go away when you depress the clutch pedal??

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel

      What should I do next to hold the head on

      By MBS206 · Posted

      When you pulled it off, there is no signs of blown head gasket? Is it possible you have some other issues going on? Possible cracked blocked? Or do you think it's straight up lifting the head? Did you check what the head was torqued to before pulling it down (To see if possibly they're stretching, or starting to break threads out etc)?

      Chris' Toyota Mark ii JZX110

      By Rezz · Posted

      Seems like a decent result for a modded JZX110. They are bulky in comparison to the 100 and 90 models (which I'd prefer myself) but they are getting very few and far between here in JP these days. Thanks for the detailed review and the import process into the UK. I also have a car which I'm hoping to export from Japan at some stage so it's good to know if someone from the UK was interested in it. By the way the corrosion underneath is par for the course for cars which were located in/near the mountains or along the Japan sea coastline. They get huge amounts of snow every winter and the sodium chloride is used on the roads. Many cars have some kind of rubber like treatment underneath but they tend to limit it to the wheel arches underbody and fuel tank. Suspension arms and sub-frames will have similar corrosion to your JZX110 which is a common sight. See it all the time and car dealers here generally don't even mention it unless asked.

      If the sound goes away when you clutch in, the 1.5/2 way diffs are just shit, and you are a normal person. The diff is likely "fine" but driving at anything under 30kmh is a violent horrible experience. It would be exaggerated with solid diff bushings and subframe bushings if you have those.
