Hi all, so I have a well loved 79 pickup, 2wd shortbed base.
I had what we believed to be the throwout bearing go several months ago, it went from perfectly fine to terrible sound basically overnight. Found another trans, swapped with new t/o bearings and has ran great for months, no issues. But on the way home from church last night I heard what sounds like the same dreaded sound come back suddenly, though it seems hard to believe it could fail that quickly though I'm sure it can. Otherwise maybe input bearing?
Here is a video of sound.
It is present when truck is in neutral and disappears when clutch is engaged, seems to not be present in 1st/4th or at least not much compared to the sound of 2nd/4th.
To my understanding I can see how it can be the throwout bearing again, but I'm curious if you all think there is other culprits since its such a fresh swap? Funny it went from totally fine to terrible in a day.
Other information, may or not be relevant, has a strong vibration from only 50-60mph we can't seem to solve at home, (tires are new, just aligned too, driveshaft not bent as far as we can tell and Ujoints pretty new) and I've noticed the clutch is starting to get crunchy and less pleasant, holds pressure but does not feel good, I do think either the master/slave is going slowly, and I hear there is a adjustable fork on the slave end that can cause issues?
Appreciate any insight. I love this truck and the sound causes grief, as you all know well.
