first things first, did you get a good look at the clutch disc while you had the cover off? you should be able to see the clutch liner between the flywheel and pressure plate.
by any chance, did you shift the t-case into 4wd or 4wd low before attempting your curb climb? would it be possible that the t-case was'nt fully engaged in 4 low? could have been in neutral, would'nt be the first time this has happened.
if the clutch was worn out, it would be slipping in the higher gears first. it would also smell pretty badly.
last but not least, i'm not a big fan of centerforce clutches except for high performance applications. they're designed to be used/applied under heavy load at high torque and hp loads.
ask yourself this question: how long did the oem clutch last?
do you think the centerforce clutch will last that long?
another reason i don't like the centerforce units is that the clutch liner is a much harder material. so as the clutch wears, the flywheel gets worn down as well. that results in you having to replace the flywheel when the clutch needs to be replaced.
i like oem toyota and LUK clutches. i actually prefer LUK. the kit they supply includes the disc, pressure plate, throw-out bearing and pilot bearing. all the components are new, not remanufactured. they're also reasonably priced. LUK is the oem supplier for gm and dodge amongst others. my 07 dodge diesel has a LUK clutch in it......
i have installed and sold literally hundreds of clutches having worked in the transmission industry for 12 years, so my opinion is based on experience, not hear-say. i have yet to see a centerforce clutch last as long as an oem or LUK clutch.
i'll get off my soap-box now..........
