rear end problems? maybe?

Hey about a month ago i took my zj out to trails all weekend after that i took it agian in sugar sand and its like my rear end froze up it started shakin real bad vibrating and loud clunking noise, then after a few trys with exseleration it went back to normal and made it out (in 2 wheel) so i decided to take the diff cover off n check my gears everything was awsome oil was clean no shavings or metal n e where and gears were perfect aswell as pin

Well, I don't know about your " sugar sand", but I run a Bobcat at work, yeah it's a 4x4. At times, when I run into deep loose sand, it vibrates, usually indicating the tires are loosing traction. If you find nothing else wrong, you might want to look at your tires.

that's just hopping from the tires spinning.

any chance you have an LSD an the clutches are acting up or maybe the additive mixture isn't right?

i am familiar with sugar sand (hatteras) and it is very normal to have the vehicle feel like its "hopping" like your on a pogo stick when your going up a slight inclinie or even on flat terrain while in thin sand

or possibly tranny given you replaced the lines?did you eliminate the little check valve(its not bad if you did but someone will give specific name)

see its not really hoping though it feels more like tires arent spining like somthings stoping them from spining which is causein the vibration.. and wow call me stupid but i never thought to eliminate the check valve would you Recommend it? i also no used same gear oil as before n right w .. and had tranny rebuilt 6 months ago all new parts

i believe that check valve is a common failure when it sticks and causes the tranny to overheat. the only difference iv'e seen without it is that it takes a few seconds to engage when cold, especially when going straight to reverse after starting

any chance your chain is loose in the Tcase and hopping gears?

ok good deal on the valve im gonna eliminate that then and see if it helps.. it could be the chain but im not in 4wd when it does it .. it kinda softens the blow and takes presure off the rear end when i throw it in 4 high while its doin this..... but maybe thats juss another good idea for me to look at thank you

uhuh, so you have the 242 then? check your linkage to make sure your bushings are good and making it all the way into 2wd, you may just be popping in and out between gears. 242 has a lot of positions to make it through in not that far off a throw.
