It's hard to tell especially the way you described it! plus you say only in first! and this sounds weird!

One thing you should do first is disconnect the clutch from the box and see if the cable by itself is hard to move!( Maybe it's had it!)

How far between normal pedal hieght and the floor till the clutch grabs?
New clutch should be close to the floor and old will be closer to normal pedal hieght!

Greeting's All,
I have a bit of a prob with my clutch. when in first gear and taking off the clutch seems to stick a little and then just drops and then takes off. Its hard to explain but its seems worse when it hasent been drivin for a while.

I know where the ajuster is on the firewall, so if I screw the nuts towards the front of the ute would this help to make the clutch not so agro when taking off or is the clutch on its way out ??

Any idea's.
