I'm sad to say my 4Runner left me stranded for the first time. A week prior I had just finished up a 3500 mile road trip out to the PNW towing a pop-camper and had zero issues the entire trip. But this past weekend, I took a short trip out to the mountains and while driving into town I heard a noise as I pressed the clutch pedal and the pedal dropped to the floor. I coasted as much as I could in neutral, then jammed it into 1st to get into a parking spot.
My first thought was the Clutch Master Cylinder. But the fluid level was good, there were no leaks, and the Slave Cylinder still moved when my girlfriend pumped the pedal.
Next thought was the Clutch Release Fork had broken since it was able to wiggle around a lot. I had my insurance tow the vehicle home and tonight took a better look with a flashlight.
The Clutch Release Fork looks fine. The fork pivot bolt also looks fine. But where the fork pivot bolt screws into the bellhousing... that's what I heard break.
I haven't pulled the whole transmission yet but I'm pretty sure the bellhousing (not the main Transmission Case) has the threads for the fork pivot bolt. So it looks like I'll need to track down a R150F transmission that I can take bellhousing off of. I guess the good news is that I don't need a whole new transmission. Anyone in the Front Range area of Colorado know of any leads?
