Hey everyone, any ideas on how I'm supposed to grease this thing? Lots of rattling when idling in neutral or lower rpms under a load. Can't find a grease fitting anywhere. Any help would be appreciated. Thank you

Noisy throwout bearing, no grease fitting?

It is supposed to have a remote gease line. There should be a rubber grommet it the inspection cover. Combination of brass fittings to attach the line. 1/8" pipe port on the bearing will be on the top or side of the of the bearing.
Doable without tearing apart , but not fun.
Biggest question, is the fitting broke off?Rideandrepair, magoo68, 650cat425 and 2 others Thank this. -
Not sure about the inspection cover, my truck came with it missing. However, I did miraculously come across a video on Youtube on replacing the clutch brake and it had the same style fork as mine and the line was dangling from the top right portion. Here's a photo on where it should be, I'm going out in a few minutes to see if the fitting is there or missing. Thanks!

Its gonna be above that on the top side. Gonna need an inspection camera or a mirror to see it. The remote line usually mounts on a bracket LF framerail.
If you can get a fitting in it you might be able to just put a whip hose on it.Rideandrepair, Matt1924 and Dave_in_AZ Thank this. -
Sometimes there’s still an additional grease fitting installed on the very top of the throwout bearing even though you have a remote line, you have to reach way up there and feel around for it.
Right above and inward of your circle is usually where the 1/8” pipe threads in, sometimes there’s a 2” nipple to extend it out past that cast nub (where your circle is) with a 90° elbow to exit the inspection cover, other times the hose will exit out the driver side of the housingRideandrepair and Matt1924 Thank this. -
Grease fittings are in the bellhousing, passenger side about 4 o'clock.

Thank you all for the responses. The fitting ended up being in the top, and I did have to use an inspection mirror with flashlight to find it up there. Was able to fish my grease fitting up to it and line it a bit. On the side of the bell housing is just a rubber grommet.
Anyhow, greasing it up didn't seem to make much of a difference, it may be worn and need replacing. With 570k on it now, been thinking of replacing the clutch while in there anyway so I think I'll wait another month or two and get all that knocked out in one go.Rideandrepair and Goodysnap Thank this. -
I'd add a remote line to the new one to make life easier.
