Drive train bucking

[Jackstand]

I recently installed a rear locker in 2004 3.7 manual transmission Liberty,
At slow turning speeds I am getting a drive train buck only in gear most, I know my throw out bearings is bad and possibly pilot bearing as well, I believe the clutch has a sprung hub I’m wondering if it could be the clutch hub with bad springs, has anyone ever had any issues with this?

What locker did you use ?
If a lunch box style then that could be part of it, they don't always play nice like a real locker does
Is when you are on the gas or just coasting like

it’s a Spartan lunchbox, locker is disengaging correctly, it did that before the locker once in a while under the right conditions but now it’s just that much worse, it also does the bucking or more of a clacking sound when it goes from having a load on it to pushing in the clutch under extreme conditions

Here is the 2005 factory service manual. (no 04 avail) Hope this may help you re the pilot & throw out bearing etc.

Thanks definitely lots of useful information, have a feeling I will be doing a clutch, master/***** cylinder very soon, increasingly harder to get into gear without pumping clutch especially when cold.

really? ***** just checking. Also could it be worn u-joints? I know i’m going to have to change mine too (8x,000 miles on the factories - i assume).

U-joints are good, radius arm bushings are good and it has an iron rock off-road upper y link which is also good
