I am not educated at all about trans. My 5sp shifts great but I am getting this rattling, metalic, chinging? sound mostly noticable in the low rmps like 2700 and below, but that might be because I cant hear it over my exhaust and or intake any higher than 2700-3000rpm. I looked under the hood at the tranny and the thing I am pointing to in the picture was slightly rattling and when I touched it the sound stopped. what is this thing? why is it making noise? hard fix? It has gotten a little bit louder over time but it is not very loud. I feel dumb asking but I really know nothing about tranny's. Thanks for any help.
When I say I touched and the sound stopped it was because my finger stopped the part from rattling and making the noise.

That is the fork rod for the throw out bearing which disengages your clutch. I would say the throw out bearing is failing although many cars go many thousands of miles with failing throw out bearings. When you press on it with your finger you are tightening up the play in the worn bearing and therefore quieting it down.

 

How much play does it have (clutch out, engine off)?

If you have the tools, I suggest pulling the slave cylinder out of the way, then seeing how much it moves then. It's possible that it's rattling against the pivot ball, or against the TOB, or it could indeed be the TOB itself.

Does it have much up/down play, or just forward and back? Check for in/out, as well.

 

Good post Pmohr! I agree, it may have slipped off the pivot ball under the housing. There's a spring that is supposed to hold it (slips over the ball) in place and it'd be odd for that to come loose, but it's possible I guess. Otherwise, the car shifts ok you say ... how's the clutch feel? Any difference in release points at all?

 

it has some up/down play not allot but you can move it up and down a few centimeters. it does not move foward and back unless i really push on it and it moves to the left and I think that is soposed to happen. But anyway I dont know what the slave cylinder is I guess I will look it up. The clutch feels the same as it always has, although it does squeek and moan.

 

the slave is the rod that pushes that fork .... 2 (14mm) bolts holding it down to the trans case. it's ok to move a bit and it doesn't seem to be off the peg, so IMO, it's fine and you are just tweeking.

 

Ok thanks, and maby I am tweeking but the sound it is making is not normal and it has gotten slightly louder over time. So its natural for me to be worried about the part going bad. Like the TOB that people have suggested.

 

any xtreme torque steer??

cause sounds like diff carrier bearing
all tho with half shaft design might not torque steer that bad still sounds like diff bearings lol

 

Well when the car is stopped so is the diff, plus the fact that it goes away when he touches the release fork...TOB.

 

Throwout bearing would not make noise when the clutch was out though??
only while engaging and engaged

i thought this noise was during movement??

if its a stand still noise when clutch s OUT it would be the input shaft bearing
this failed n my 3rd gen

 

^^^^ How do you figure it's the IPS at all ... from what he has said? Why are you "guessing" at everything when there are people posted on here that have torn down several transaxles before and none of us have thought that by what he is saying? Where do you get the IPS bearings being the cause? ??? ? True, Nissan manual trans have a reputation for bad bearings (both diff and IPS) but you are just guessing and it's obvious. Not to mention that bad diff bearings tend to cause leaks ... which is noticable and common.

Sounds like the fork is a bit loose or it's maybe the TOB .... can you post the noise? Put it on YouTube or something so we can hear it.

Oh .... and 95maxdvt - welcome to the .Org mate!

 

My trans. has been rebuilt. well it has all new bearings. And the sound stoped so I don't know what happened, but with my luck it will start agian in a day or two. I will try to post the noise if it comes back but yea it must be the fork was loose or the tob is slowly going bad. It was a long time ago when the tranny was rebuilt and I know that there was 6 or 7 bearings replaced.

 

your right i didnt read closely enough anything you can stop the sound of by applying pressure def isnt in internal bearing
by TOB arent you refering to throw out bearing?
maybe im confused and never had any experience with fork

usually ips causes axle seal leaks correct?
never seen a leak due to diff??

Thnx 4 the welcome lol n next time ill try n read a lil more carefully

 

The input shaft is nowhere near the axles (unless you consider being part of the trans is "near" enough)

and from above...most throw out bearings are noisy when there is no pressure on them (explained in my first post)
