Default Shuttering Clutch

Hey guys. So the 4Runner has a pretty bad shutter in the clutch when starting from a stop. I suspect something in the hydraulics. I bled the clutch and all the nasty fluid and replaced with fresh. When I did this, it seemed to be fixed at first, but after a day or so of driving the shutter was back. I'm not loosing fluid, so maybe air is getting in the system? Bad slave cylinder? I would like to get it fixed before I head to Moab on Thursday. Thanks guys!

Also there is an audible whining noise until you depress the clutch full, and then it goes away.

Thats probably the throwout bearing squealing.

the shudder may mean oil contamination. does it have a oil leak oil coming from the bellhousing?

Nope no oil that I can see. I'm just confused cause the truck drive great after I bled the clutch. And the pedal felt different and better. Now the pedal feels like it did before. Stiff and not very smooth.

I had a significant shutter on my 40 before I replaced everything. My pilot bearing was shot (No bearings left, just inner, and outer races) The torsion pads/springs were shot, and the throw out bearing was bad. The combination of all of the above prevented the pressure plate, and flywheel from getting even contact and caused the shutter.

How many miles on your clutch plate?

No clue on the mileage. Bought the truck last spring. I had a transmission put in it though and had the clutch looked at. I didn't have enough $$ to do both things at the time, but everything checked out.

I agree with new TO bearing. Get a new clutch master/slave or rebuild kits for same.

I swapped in a different slave cylinder this after noon. Seemed a whole lot better but there was still some shuttering.

Can you adjust the clutch fork? Is it in spec?
