ok 1st thanks for reading this
98 sport
i think i need to replace my rear seems to be real clunky sometimes
when i stop and start
i checked all the u joints they r good
i was figuring if i have to replace it why not upgrade if i can
this jeep is completely stock and wont be doing any rock climbing
fishing and hunting mostly
ive been reading some of the threads here
and would like some experienced advice

and can anyone tell me what t/c i have by the tag in the pic

The rear end is a 8.25. Its a good enough axle and I doubt your "clunking" is coming from it. If you want to "upgrade" you can get a "lunchbox" locker for ~250-300 bucks. That way you would have Posi to help you get back to your hunting stuff.
I would check the transfer case, maybe a stretched chain.

The 231 is a good TC and should give you no problems. They are known to stretch chains though.

any ideas on the rear

U-joints can make a clunk- and are cheap...

check your ubolts are tight

Check your trans mount. That could be the culprit.

Ujoints, Trans mount, Ubolts and the slip yoke will all cause the clunking. Take of the rear DS, check to see how good the ujoints and replace if needed, then pack greese into the slip yoke the goes into the t-case before replacing the DS.

All cherokees develop this clunk, some call it the "Chrysler clunk", I help mine out by packing the slip yoke. A diff fluid change never hurts

ok guys
thanks for all ur input
been checkin things out
i checked all the u joints back in feb when i bought it
had to replace only the front axle joints
the trans mounts r ok too
as i have been paying more attention to the clunk im realizing it

so does anyone know more about the t/c chain
can i do it myself or is it complicated

My cherokee dosn't clunk either when it is cold. It feels like the trans shifts to drive and reverse more glently when cold and takes up the driveline slack before fully engaging.
