Alright ive been battling this whirling noise for sometime....Basically what happens is after 1st gear when i switch to second a whirling starts to apprear...if i let off the gas quick the whirrling become almost squrlish noise and sometimes pops the car out of gear. I was first told crossmember wasnt tight..which it wasnt so i fixed that....i re drilled the rear side to a 1/2 inch due to it stripping. So the noise is still there....then someone told me Wheel bearing...but the noise goes away when i push the clutch in. Then they say TOB, bought one from Greg V along with the clips and even changed to a 6 puck unsprung disk thinking a spring in the act street disk was loose. Well after this weekend i installed the new componets and it still makes the noise. I am lost and need a resolution quick...wifey has lost patience on this car.

SO recap:
Crossmember good
TOB and CLips Changed
New clutch disk
Wheel bearings ( assuming fine since noise goes away when i push the clutch in.

Could the tranny be own the way out...i can be driving and it will pop out of gear. It never started doing this untill the crossmember droped in the rear and i had to drive it 25 miles home like that....after that day it started if i recall..

Thanks for the help

Sounds like input shaft bearings

Is that inside the tranny?? Cheaper to buy another tranny??? I need this fixed asap....

Any others??

Any others??yes that is inside the tranny. I think that is the main giant shaft inside the tranny, you can't miss it.

Bearings, probably not too expensive. Might be hard to do those though, seals are easy, bearings are not.

i found a link with a input bearing noise and it doesnt sound like that...its only happening after like 30 mph ...

that is fucking weird. your last comment screams wheel bearings.

you need a tranny expert.

could be the forks or something complex like that.

Yeah thats what i thought but someone was telling me if i sway back and forth on the road i should hear it more. I also had someone that has heard the wheel bearing before and they stated its clearly coming from the drive train...Im gonna video record the sound tonight...its awfull....

I had to replace the tranny in my Max due to input shaft bearings and diffy bearings and it would make some pretty loud noises in gear, rolling, free reving, everything basicly. The easiest way to check input shaft bearings is to free rev the car (in neutral). You would hear a whirring from the input shaft. (this works best when parked near a wall). I cant imagine it being anything else because when you are rolling the wheel bearings, diffy bearings, and the gear youre in will still be moving regardless of the clutch being pressed in.

When im in the car sitting in nuetral theres some chatter...when i rev up though no noise. When i push in the clutch and hold it in the noise goes away i let go it make a loud screch noise and stills whirls. I just changed the tob and clips and clutch disk. The xmember is all the tightend with washers. Its like under heavy load it whirls when i first start out it makes no noise...ive been trying to record it but i cant seem to make a sound clip so im gonna make a vid clip.

yeah what your describing definetly seems like the bearings in the tranny being loud, almost all my nissan manual trannys were freaking loud like that, its annoying but i just got used to it, even with a good gear oil in it, neatral at idle would make a light chattering/clunkity sound push the clutch in and it goes away, this is cause by only two things, either the tob or the tranny, we have loud trannies like that though, hell the b14 tranny i got from a friend with 40k miles on it was just as loud as my b13 tranny that had 250k original miles on it. lol. so thats probably your problem, good luck

yeah but it pops the car out of gear sometimes...so i cant really drive on it safely....

I have a noise that I thought was tob and I'm getting ready to do some surgery. Mine will do it at idle and go away if I push the clutch in. If I have it in neutral and let the clutch up real slow it goes away, or just does a light little whistle sound.

yeah that noise is definetely the bearings inside the tranny. again ours are well known for having loud trannys, i know all the ones i had were loud.

Hey guys, when you push down the clutch pedal the connection between the engine and transmission is no more, ie. the trans input shaft and all the bearings and other shafts in the trans stop moving. Push in the clutch and the throwout bearing STARTs moving. If it starts making noise when you push the clutch, it mostly has to be the throwout bearing. If it makes noise when the clutch pedal is out it mostly has to be the trans or something on down the line. If the clutch is dragging and not releasing correctly the trans can still be part of the problem with the clutch down. If the clutch is adjusted tight enough that the throwout bearing is always contacting the pressure plate, the problem can be the throwout bearing. On vehicles with pilot bearings the trans can still turn and cause noise with the clutch down, due to the pilot bearing failing and dragging the input shaft with the engine.
Seems like maybe some of you are confused about that so I thought I'd lay that out to help you understand.

Benito, your's sounds like trans problem.

Dreamer, your's most definitely sounds like a trans problem. Does it still pop out of gear since tightening the crossmember bolts? If so, it sounds like it'll have to come out anyway unless the shift linkage isn't allowing it to go all the way into gear and/or pulling it back out of gear.

Shift linkage is good. It goes in nice and smoothly no grinding of the gears...You know i never changed the pilot bearing when i did the clutch kit...but i dindt think it was that big of a deal..

The whirling noise is there the whole time...when i change gears when it engagess it makes a loud squirling screech noise and stays that way unless i press the clutch in and let it re-engage.

I haven't installed the new trans in mine yet so I don't know, but the input shaft on my LSD on the floor looks like it doesn't take a pilot bearing. ???

You have checked the fluid level, right?

This is what i was afraid of. The funny thing is it has only done this since I swapped the Ve in. So what do I replace? It works just fine, but sounds like hell. I'm getting ready to do this up after I buy a second vehicle. Sorry for the thread jack U12bb.

I'd make sure the TOB arm isn't making the bearing ride on the clutch first. If it isn't that then I'd have a bud help and use a 2-3 foot long stick against the trans while someone pushes in the clutch and releases. Hold the stick against your ear and place it on several spots from the side of the engine(make sure you stay away from moving parts) working back to the rear of the trans. You should hear when the noise is louder and get an idea from that too. If you don't hear much from the trans with the clutch out it probably isn't the trans. I'm not a trans expert so if it's def. coming from the trans then I take it to a trans shop.
