Replacing the input shaft bearing in a Honda Civic and Civic Del Sol Transmissions

Identifying:

Transmission makes grinding noises at lower rpms in gear and chattering noises at idle in neutral with the clutch out (engaged).  Chattering/grinding noises in neutral and in gear go away as soon as the clutch is pressed in (disengaged).  High rpm whining may be present also in gear with the clutch out.  The transmission will need to be removed, opened, and the input shaft bearing replaced.

If the noise occurs when the clutch is disengaged (in) but not engaged (out), then the problem is most likely your throwout bearing.   Throwout bearing replacement requires the transmission to be removed, but the transmission itself will not need repair.

Tools needed
10, 12, 14, 17, 19, 32 mm sockets
Impact gun (may be needed to remove axle nut)
Breaker bar (removing axle nut)
Ball joint separator
Pry bar (removing axles, transmission)
Hammer
Screwdrivers
Needle nose pliers
Punch or awl (removing shift linkage pin)
Helms Manual (92-95 Civic shop service), a definite must!
Haynes Manual (preferred, but not required)
Transmission jack (you can try doing it by hand, but I wouldn’t recommend it)
Jack, jack stands
3 Jaw Bearing puller (cheap at harbor freight.  Not required, but preferred)

Parts needed
Clutch kit, or at the very least, a clutch alignment tool
Bearing grease
Silicone gasket maker
2 new axle nuts
Input shaft bearing
Input shaft oil seal

The helms manual is an absolute must, available here.  If you don’t want to pay the crazy price, download it online, its available in lots of places.  The haynes manual is also helpful, as our online sources reference at the end of this article.

A few tips before you begin:

  • Organize bolts/small parts in ziploc bags and label them!  Do NOT skip this part!
  • Buy a clutch kit, your taking off the transmission already, you don’t want to take it off again to replace a clutch.
  • Take the flywheel off and get it turned if you put in a new clutch.
  • Do yourself a favor, get 4 jack stands and jack the car as high as possible on all four corners, it will be worth it.
  • If you have an intermediate driveshaft, you do not need to remove it from the rest of the driveshaft.  Just remove the entire axle.
  • When you are attempting to spread the snap ring to separate the transmission housings, pry apart the housings carefully.  This will make it much easier to separate the housings.
  • Make sure you align the interlock guide bolt with the groove under the shift arm when you reassemble, its easy to forget this part.
