Clutch knocking ?

I have a 2002 Tacoma 5 spd 4x4. I have noticed when i crank the truck up for the first time in a few hours or especially in the mornings when I let out on the clutch it feels like somethin is grabbing and its hard to get the truck to move. Also when I push the clutch back in something will make a loud knocking noise. anybody know what the problem is. ? by the way its not my ebrake.

 

how many miles?

 

156,000

 

have you checked to see if your clutch slave or master cylinder is loosing fluid... ??? sounds like its doing that since you said its doing it after it sits awhile

 

if your not loosing fluid, it maybe your pilot bearing..

 

Pilot bearing would make noise all the time when it starts to go. It supports the input shaft of the transmission and is pressed into the flywheel. You might have been thinking throwout bearing.
I would suspect a clutch fork or a throwout bearing problem. A close inspection while someone operates the clutch might reveal the problem.
