my 93 zj has the new tranny in it now. i couldnt do it because i was in the hospitol for a long time, luckily my bro and my buddy changed it for me. runs good but now when you start it there is no check engine light, but after it runs for like 10 minutes or so it comes on.. had nyone ever had that happen???? maybe have an idea whats doin it like that?? thanks
-
umm... take it to autozone and have them run a diagnostic on it. if the check engine light is off when its not running but turns on when the engine is running it should still throw a code. my jetta does it and my bosses jeep was doing. he had 4 codes but no check engine light. so yea take it to autozone they do it for free
-
yeah im sure i will. hows your zj?? i love mine i got the new tranny in it, the 5.2 tranny isnt easy i guess. and i got new new bfg mud terrain km2 33"s on it and i have a winch and the winch bumper i have to put on, the rock sliders need to be put on, new t'case novac shifter and both new differencial covers, lots of money but its all fun, i like our jeeps cause theres not a hole lot with the lift and other
-
my zj is awesome just put it up to 5.5 still on 31's cuz 33's are expensive... other than the sliders coming in i cant complain its dandy lol

My guess would be a vacuum leak in the Evap system. My wifes Liberty and my XJ both have had the evap leak code. In both cases I replaced each piece of rubber in the system from front to back and both times it fixed the problem. If this is the case, just make sure you get rubber that is safe foe gas fumes. I needed 3 differnt sizes and it was only about $5 and a half hours worth of work.
-
Get auto zone to check the codes it is a problem going into closed loop an evap code would come as soon as the engine was running
-
yeah i drove her toady for a bit and i didnt get a check engine, maybe i was gettin it cuz i didnt run for a while cuz i had the bad tranny maybe it over it now, bit did get the damn death wobble. i cannot go on the highway and it suck and if i drivin i hav to dodge bumps
-
we should get together this week and i can check it out if youd like
-
yeah maybe next week if you have time or anything. how do you think the chances of figurin it out will be??? how far from me do you live?? i live in canterbury. i got a few trails out back to that i made for the 4wheeler and the jeep. nothin to serious but fun
-
i live in waterford, we can work something out man... as for the jeep part... that was ironically the part i needed but i might snag the doors im doing a cool little half door thing, same thing as andy..
-
im sure we can figure somethin out. it would be cool if your zj will make it up here though so i can check it out and maybe we can use them a little bit. theres all kinds of places around here besides my woods, theres a couple good places with good hills and usually some good mud
-
If you can get your heep, er, i mean Jeep (lol) to my place, i've got an OBD II diagnostic tool. It reads all paramiters real time, can look at stored codes, etc, etc. I can even load the software on a laptop and watch/record a drive to find those intermitant faults. I'm working from home all week (well, off on Fri), so PM me if interested
-
thanks man but the jeep did that a few times and now it doesnt come on anymore. probably cause the tranny got changed and didnt run for a while so that might have messed with it. i drove it a lot since we got the snow and no check engine. that good for me i guess. i love my zj i just pissed about the death wobble. but im thinkin maybe the passenger side ball joint. ive been hearin a lot of clunkin over there while drivin
-
Ball joints don't clunk probably a unit bearing if it sat for awhile
-
you talkin about the wheel bearing or what? i dont know a unit
-
you talkin about the wheel bearing or what? i dont know a unit
yes same thing they call it a unit bearing b/c they are no are build-able.
Modified
Sry meant to say not re build-able.
-
yeah its one piece on mine its the hub and bearing you have to buy it in one piece cause the bearing is in the hub or whatever but i guess i could try it
-
but why would that clunk when you hit a slight tiny bump on the road??? and you really dont think the balljoint would clunk. im just hope whatever is makin that noise is why i get the d/w
-
you talkin about the wheel bearing or what? i dont know a unit
Jeeps don't have a sevicable wheel bearing, it is a one piece "unit bearing". Tnhe unit bearing consits of the part between the axle shaft and the wheel studs.
-
yeah. i was lookin in my chilton book and saw that but do you think if thats bad would it clunk on a tiny bump or basicaly no bump and would it cause the death wobble??? thats y i was thinkin the ball joint

Put a jack under the axel on one side. Jack up the axel till the front wheel comes off the ground enough so you can fit a 3 or 4ft pipe or bar under the tire then lift up on it several times while someone is looking at the ball joints. This will show the play in the ball joints. Then do the same for the other side. There should be very little play in them & I mean VERY little play.
Then to check your track bar you will not need a jack for this. Just have someone rock the steering wheel side to side just enough till the wheels are moving slightly & look at both ends of the track bar. There should bo NO play at the axel side. There is just a bushing at that end. Then the other end of the track bar that attaches to the frame is like a tie rod style & might have a little play but VERY little. At this time you can also check all the other tie rods on the drag link & link from pitman arm to drag link. Also you can see the play in your steering box. Your steering stabilizer is also very important so make shure that is tight & not leaking.
All these parts if warn can & will cause D/W. Then after replacing all the warn parts then a good alignment is needed.
And if Ball joints are warn extreamly bad then you will hear a clunk noise from that side. My friends 98 Dodge Ram 1500 had both upper & lower ball joints extreamly warn & when I went for a ride in it one day herd the clunk noise. Checked them & it was both on the LF. The Dodge Ram is like a big Jeep. Almost same style suspention just bigger.
