My truck has had a squeaky clutch for longer than I’d care to admit.    Here is a video I took of the noise:

I bet that sounds familiar to a lot of you manual transmission Toyota owners!  The culprit was the point of contact between the clutch fork and the bell housing’s pivot stud.

Here’s what I did to lubricate:

1. Remove slave cylinder.  Just take out the two 10mm bolts and let the cylinder tangle, it will be fine as long as you’re not bending its fluid lines.
2. Remove the boot from the fork arm
3. Move the arm away from the stud and lubricate that point.

I used white lithium spray via its tube but I imagine many different products would work fine here.  Just got back from a drive and it was so nice having a quiet (and seemingly silkier) shifting experience!
