You have to be able to pull the old bearing and replace it with the input shaft in place (it takes a special puller and installer). Not being able to do that (like me), the transmission needs to be almost totally disassembled to remove the shaft/bearing from the case. There are clearance issues with the countershaft and mainshaft that cause this. If you go that way you still need a bearing splitter and press to get the bearing off and press the new one on. Because you have taken the front cover off the transmission, you will have to do some shimming between the case and outer bearing race.
It is the same thing as a pilot bearing. Goes into the rear of the crankshaft to support the input shaft of the transmission.
The bearing lets the belt pully free wheel on the compressor input shaft that the clutch is attached to.
The spigot bearing AKA clutch pilot bearing, is the bushing that is pressed into the back end of the crankshaft and supports the input shaft of the transmission.
It will be due to the input shaft bearing in gearbox.
Your input shaft bearing is going bad, it will get worse if not replaced
on the blower most bearings are flange mount, and will have a Allen set screw locking the shaft to the bearing,
you don't, you have to replace the whole drive shaft.
Input shaft bearing is probably bad, especially if it is noisy in every gear but 4th
The throw out bearing will only make noise when you press the clutch pedal. If the clutch is new, the throw out bearing is a required replacement in a clutch job. Sounds like a bad pilot bearing. Not enough info in the question. I had the same problm and it was input shaft bering, AND the counter shaft bering. Replace them and sloved the problm.
you will have to have the axle pulled at a shop.the bearing slides along the axle shaft and seats in the axle housing.
Only difference is a bearing in the end of the cranksaft to support the input shaft of the manual transmission.
The slave cylinder is on the input shaft of the transmission at the throw out bearing. The transmission will have to be removed to change it.
