squeeky-grinding

[long84les]

i just turned on and started driving. and out of no where hear a squeeky-grinding noise. i look under the car is its louder seems to be coming from somewhere near the engine. like maybe the transmission or transaxle. when i push the clutch in the noise stops and starts again when i let off.. but when i pick up some speed it goes away all together. does anyone have an idea of what it may be?

Maybe TOB?

Yep could quite possibly be the TOB.

Before I even read your post, I thougth TOB from those first two words "squeaky, grinding...."

Yep... Its seriously either the TOB or the Clutch might be going bad... I thought mine was a TOB,,,, but it was where the TOB pushes the teeth of the clutch. Half of them were bent in and the other half were fine... So it was screwing with the TOB. But to get the sound to go away, I had to be at like 7500rpm

 

[long84les]

what is a TOB and where do i get one at, how do i fix it? how hard is it to fix it myself?

A TOB (Throw-out Bearing) is a bearing that rides off of the input shaft of the transmission, and when you push your clutch pedal, your clutch release fork pushes the TOB into the pressure plate's fingers to take away the pressure the pressure plate provides to the clutch disc to grip the flywheel. Basically the whole assembly just releases the pressure from the clutch disc so that you can stop, start, or shift. I think new OEM TOB's run around 35 at autozone. You would have to take the tranny out of the car, put the new TOB on, and re-install the tranny. if it were me though, i would replace the clutch while im in there. Hope this helps.

Thank you! Yeah... I'd just buy a clutch kit... if the car is still drivable... go for a nice stage up upgrade to your current clutch, it will come with a TOB.

so the TOB are the problem. how hard are they to replace? where in the trans are they.. and you said a new clutch kit will come with them? does anyone sell a transmission rebuild kit with new "whatever" is in there?

The TOB is not a part of the transmission, rather a part of the clutch system. It will be located between the clutch and the clutch fork, which is between the transmission and the motor. (Inside the bellhousing) When you pull the transmission, the TOB will be the round thing on the input shaft and fork.

A new clutch kit should come with a new TOB. The awesome clutches from SouthBend Clutch do come with OEM TOB's. Changing the TOB is nearly the same amount of work as changing the clutch, so if it is very old, or of an unknown age, now would be the opportune time to replace it.

Things to remember while replacing the clutch & TOB.

1. Evaluate the condition of the Rear main seal. (crank seal)
2. CV boots
3. Make sure you loc-tite the bolts attaching to the flywheel through the flexplate.
4. Make sure to unplug the VSS prior to dropping the transaxle
5. Remember the bellhousing bolt locations because they are not all the same length.
6. When re-installing the tranny always remember to have a beer in one hand and friend to help because lining up the input shaft in the clutch is so frustrating.

thanx alot for the info is there any other tip or tirck to taking a transmission and clutch off? what are the usual problems that i will come acrosstaking off the trans and clutch. i know with mitsubishi theres always a hidden issue.

its basically a straight forward process. first go around the tranny, and loosen the bolts to the tranny to engine junction, just break them loose. then put the car on jackstands, with rocks or bricks behind the rear wheels to prevent the car from moving. then drain the tranny fluid, if it hasnt been changed in 30,000 miles, or if unknown, i would put the old oil back in. now you can get to the fun part, now you can take off the cross member ( the steel beam running through the bottom of the engine bay) there is also and engine mount on this that needs to come off. then i would go ahead and unmount some of the suspension, both sides too. just unbolt the a arms on both sides, then get underneath and carefully pry the driveaxle out of the tranny on both sides, then you should be able to swing the suspension to move the axles all the way out of the tranny. then take the shift cables off, disconnect the slave cylinder, and lines, and unplug the sensors. then use a jack and a block of wood and place it on the oil pan of the engine, just so the engine doesnt fall when you take off the other two mounts, they are located at the end of the tranny(driver's side) and back toward the firewall. after they are out, lower the jack from the engine, but just a little, you only have one mount holding the engine, it still needs some support. now the tranny should be facing more of a downward angle. take the bolts out all of the way, and you should be able to just slide it right out of the car.

now to the clutch and TOB. the clutch will be modular style. which is where it still uses the automatic driveplate to bolt onto, and the clutch assembly will be all together, flywheel, clutch disc, and pressure plate. also, you will find your TOB in the tranny, on the input shaft, it will pretty much just slide right off and out of the tranny.

in reassembly, you should put some axle grease on the input shaft and TOB, and also in the splines of the driveaxles for easier engagment. all else is pretty much reverse of removal. hope this helps ya out.

and actually i do have a tip for ya, when wrestling the tranny back onto the car, the TOB tends to fall off of the release fork. ive found a way to get around this by pulling the release fork back all of the way, then using paper tape, tape the release fork in position on the outside of the tranny, now there is no way for it to get loose. then just take off the tape when its installed.
