Ok this is one thing that didn't seem to bother me when I bought the car, but slowly its starting to really annoy me. I have a 90 hatch dx and when the car is parked and in neutral as soon as I let off the clutch it starts making this grinding noise. Sometimes it will be louder than other times and as soon as I put the clutch back in it stops. Also when I'm driving, the first and second gear are extremely loud and then when I reach third it stops and is normal sounding. When I'm ridin it sounds like something needs to be greased. I just don't know what should be oiled/greased or changed or whatever. My best guess is that I need to change maybe the transmission fluid? I'm not real sure, but please help with any suggestions. Thanks

 

throw out bearing....and scents your in there mite as well change the clutch..

 

Do the throwout bearings come with most aftermarket clutches. Also what IYO would be a good clutch to choose?

 

The noise goes away when you push in the clutch, correct? And it makes the noise when you're in gear or in neutral, with the clutch pedal out?

Sounds like input shaft bearing(s) to me. Common problem on high-mileage D-series trannies. Search for the procedure to replacing it; there is a write-up around here somewhere. You will have to drop the trans and open the case.

Make sure you address it ASAP. If the ISB fails, it can permanently damage the transmission case, rendering it unusable.

 

Sorry missread and almost said somethin stupid. I'll look it up. Is it an expensive procedure?

 

https://honda-tech.com/zerothread?id=596873 There's the how-to write-up.

If you can DIY and don't break anything, all it will cost you is the ISB (~$25 IIRC) and some tranny fluid. Helms manual strongly recommended if you don't already have one.

 

Alright I read that and honestly I don't have the tools or experience nessecary for that. I want to change my 4spd out for a 5spd anyway. Would it be cheaper if I got a shop to replace the clutch and bearings or put in a 5spd. Lemme know if you have any questions needing to be answered for you to answer that one. Also if I got a 5spd would it be likely that I would have to change the clutch and bearing in it also?

 

well, the clutch attaches to the engine. to get to it, you have to take the tranny out. so, the perfect time for replacing the clutch is when you're replacing the tranny. since you have a '90, get a clutch for a 90-91 and an 89-91 tranny will work for you.

 

sounds like the way to go. Anyone have a guess on how much the labor for all that would cost? Oh yeah and with the input shaft bearing/throwout bearing possibly being bad, is this a very serious problem? Any precautions I can take untill I have money?

 

Definately an internal bearing. It really sucks when people spread misinfo saying it's the throw out bearing.

Don't rule out your end bearings on the mainshaft also...I have rebuilt a few honda transmissions where the ISB was fine and these were the problem. The best way to diagnose is to open the case and spin each bearing independently. The bad one(s) will scream at you.

 

Thanks everyone for the info. I still have questions though. How much would labor be to replace the clutch and tranny? Also is this internal bearing being bad a very serious problem? Can I do anything to help it untill I have money?

I had this problem on my 91 crx si, I changed the throghout bearing 2 times and the noises were still there. Turned out it was the ISB. I just picked up a new tranny and slapped it on. All quite now!

Nothing you can really do besides replace the worn bearings. The noises you hear is from the races pitting. Once pitting occurs, wear will increase until failure. How long will this take? Could happen any minute, could last you two more years.

 

Clutch job should be around $400-450, but it will vary depending on where you go.
