my problem is after i got rained out on my epic search for my horn relay(never found)i went to pull back into my parking spot and noticed that my jeep will not roll forward in drive while idleing but it but it freely goes in reverse at idle no problem going in any gear yes the e brake was off my question is what would only hold it back in forward gears but let it roll fine in reverse my girlfriend has been drivin it around like this so hopefully we didnt damage anything

thanks

 

Facing up a hill and gravity?....

 

lol that would be awesome but no i was in my flat apartment parking lot

 

mine does that too. i just shift it like a manual. been like that since i bought it like 5 years ago. it's only my trail rig, besides, i kinda like it not shifting into 2nd on the trail. only thing is, it skips 2nd when i shift it on the road.

i first thought it was the tcu, so i swapped it and still nothing.
then others said it was my tps, swapped that, and guess what.... still nothing.

so, i don't know. gonna just live with it. i'm used to it now anyways.

 

but mine does it at 0 mph has nothing to do with shifting when i put it in drive and let off the brake it just sits there if i tap the gas it will jump forward then stop its self again but its not bad enough for my girl to notice drivin around but if you put in in reverse and let your foot off the brake it goes just fine like its supposed to with nothin holden it back like the brakes r on in forward but not in reverse i dont get it

 

im not too good with auto trannsmisions i am pretty good with manual though i can take one apart and put it back together like its my job.. but ill try to figure this out.. does it smoothly stop after you tap the gas or is it rough? does it roll if you put it all they way down into first or does it do the same thing.. if it does the same thing when you manually put it in first then try second if it goes when you put it in second its your tranny for sure.. try these things and tell me what you find out

 

torque converter maybe

 

i tried it in all gears does the same thing im just gonna take wheels off when it stops raining check the brakes eliminate all the stupid stuff first ill post back up soon as the weather gets better i wish i had a garage thanks for all your help

 

okay well if it was the brakes it should do the same thing in reverse but its worth a look .. pull of the rear wheels and if you cant get the drum off without alot of force id adjust the e brake cable and for the front rotors take the wheel off and see how hard it is to spin the rotor by hand .. you can also adjust those

 

umm, no. one set of shoes is self energizing...the auto adjsuters use this to take out the slack. if the adjusters are mucked up, park brake cable is binding, or somethings come loose in one of the drums, you can get resistance 1 way only. this is one of the things that was wrong with mine when I picked it up cheap: solution was new hardware ( including new star wheel adjuster) , new pads, and setting up the park brake for corrct play. hasnt done it since...if nothing else, check that the pads are pulling clear of the drums, too.

oh yah - I've also seen the bind up thing happen ( not on a jeep) when the p-brake cable has snapped inside the drum - loose end got lodged in the shoe, and was jamming the brake up in one direction only.

 

did you check the fluid level
worm it up
park on level ground check with it in park motor running

 

Bent tierod or toe in on front tires set too far in.

 

of course it was on level ground and fluids were alright i think ulendo is on the right trail because i just recently posted on another forum about a clunk comin from my rear wheels not while drivin but when i grab and shake them some one told me if rear wheel bearings were bad endplay would be so bad would cause rear brake issues is rainin bad right now but i think my rear brakes and wheel bearings r crud
would excesive endplay cause my rear shoes to pop out of place or am i back at square one??

 

well one prob on top of the next does anyone know where the horn relay is on an 89 xj ???

thanks

 

endplay wouldnt do it - everything mounts relative to the backing plate / bearing mount. but, the clunk wouldnt have to be endplay - loose shoe, or a loose adjuster could do it too...given the issues you're describing, I'd jack up the rear end, and start tearing down the brakes, starting with whichever side has the clunk..
