gearbox problems II

follow up of http://www.ozhonda.com/forum/showthread.php?t=65564

...my ek civic is having some noises in the gears while in motion (but silent while gear is being changed and clutch is in), a kinda grinding noise sounds like bearings (i am thinking perhaps thrust bearings?) alot of mechanics have told me too try changing gearbox oil first.

audio files:

me revving in first gear (its more obvious on my shit phone audio recording in first, u can still kinda hear it later but i want u guys too hear the grinding/bearing noise).... the noise is made right after i said "two thousand revs" (9 seconds in)

recorded my engine idle with bonet open, anyone hear it there kinda as well?? like a grinding (it halts when clutch is pressed in past friction point)

now i have taken my car too a few mechanics, booked my car with honda in 2 weeks for a quote .. but i can honestly say i trust you guys alot more than they do. of course a mechanic has the advantage of being there too see the car but if anyone can still give me a few things to look out for or inspect then its much much appreciated!

if its no noise when the gearbox is disengaged (clutch in ) then it sounds like the input shaft bearing for starters.

always do the simplest things first to rectify a problem. So try the gearbox oil change first and if that fails then it'll more than likely be an input shaft bearing like ben said. Gearbox out job yo :p hope you can live with the noise!

If the clutch engaged and the noise gone and the clutch disengaged noise come back again and when you revving up the noise going louder, it's the input shaft bearing problem. if the other way round it's the clutch bearing problem.

How i know that? because i just got my input shaft bearing changed today and all the noise gone....

[steve88]

input shaft bearing easy too change?

obviously not:

:D swapping my gbox with benson seems feasible

just crank up the music :p I've got a bearing noise as well most likely thrust or input shaft bearing and it's nothing a bit of music can't cure hehe.
There is absolutely no harm in not changing the bearings imo it's just a little deformed so it makes the noises every revolution it does, well that's what I think

Problem is , the ISB will only get worse and likely fail eventually. It will last for awhile ( my last ISB lasted about 15,000 of driving whining before it i dropped teh box and replaced it) Its something you have to change soon :)

IMO - save up for a new clutch and maybe flywheel too - drob the gearbox and replace the ISB , and whatever other bearings might be on the way out at the same time , to save labour and time.

[steve88]

im swapping my gbox probably. but i wanna keep my old one so i can tear it apart and recondition it myself (im still a noob on cars :p)

i hope it lasts, i dont have the money JUST yet lol.

err.... did you hear what was said above?
The input shaft bearing or thrust bearing is a clutch related problem. Not a gearbox problem. CHanging a new cluch is like $500 -600(labour is about $250 to $300). A new box could be very expensive, + labour to put it in. smae price as getting the

[shadou]

yeah but to replace the ISB you would need to remove the gearbox and open it up to be able to replace it. But yeah if your clutch is on it's way out say in the next 20k-40k save up for a new clutch set and replace the ISB while the gearbox is out anyway. Throw in a new thrust while your at it and if you get a dodgy mechanic tell him to replace the spigott as well

The ISB is located INSIDE the gearbox dude :) So that is a gearbox problem.
The THRUST bearing / release bearing is located on the pressure plate face and outside the gearbox.

Point is , its about $250-300 labour to replace 1 , then you might as well put another few $$$ or so on replacing the ISB and other bearings while the gearbox is dropped :)

[steve88]

ah so you guys recommend try and push the life of my ISB so i can wear down my clutch as much as possible?

i am pretty sure its the ISB and not my thrust bearing

2 mechanics both drove my car and said the clutch is just fine, i can honestly say that too it never slips. considering i got 170k's clocked up, if i had the original clutch ... wouldn't of it replaced by now, ie. me not needing a new one?

[shadou]

wow you must baby your clutch, should be like near its end if it's still the original one.

[steve88]

i dont know if it is. honestly this car hasnt got much of a record going, just up until 2003 it was serviced by honda. i suppose last few owners must of been bigger tight asses.

no way too really feasibly check if its been replaced eh?

[yesiamaturk]

i have the exact same problem in my car but, i can only really her it in 1st and second the most and as im downshifting its even louder

[steve88]

depends too.. i can only really hear it 1st/2nd, i have too really really listen to hear it on 3rd
