Technical Advice and Questions / 93 Xj Stalls

« on: December 10, 2009, 12:23:02 pm »

It just stopped running two nights ago on my way home from work. It was running fine for the most part. Every once in a while while driving the RPMs would drop down to nothing and then kick back in. The tranny would also unlock and lock back up. It seemed to get more frequent and now it wont run more then a few feet without stalling. While looking for loose plugs or bad wires I found my wires to my O2 sensor were pulled tight up against the exhaust manifold and melted through. I seperated the wires and checked them out. The casing was melted off but the wires were still there. It still wanted to stall out after I seperated the wires to make sure they didn't short. I've read as much as I could on NAXJA about stalling Xj's and came up with bad CPS, bad MAP sensor, bad ECU, bad grounds in the battery, bad battery, bad alt., bad fuel pump relay, bad fuel pump, bad wires going to the fuel pump. And a few more. I checked my battery connections and they were good. I bought a new CPS, and a new MAP sensor, I'm waiting on a nicer day to install the two sensors.

Does anybody have any suggestions on what to check?  I'm lost with this. And the worst thing is I have no place to work on it besides out on the street. So I'm at the mercy of mother nature.

Technical Advice and Questions / ? about silver Yj at Mt Zion O.R.

« on: May 10, 2009, 11:56:54 pm »

I was at Mount Zion off road Last night and saw a silver Yj with a coil conversion on the front. Does anyone know this jeep and the kit he/she used. I was tired and waiting to meet Rusty Xj there and saw it in the dark. It looked like a bolt on kit and I wanted to see how it worked. If it wasn't bolt on it had extra stuff bolted on the axle. I'll have to go back when it's light out and I'm awake cause now this is bothering me. I don't know why but I just want to know what was going on with the front axle.

Technical Advice and Questions / AHHHHHH!!!!!

« on: April 19, 2009, 11:47:10 pm »

I love it when I have a few hours to myself and think "Hey I could do this quick with the Jeep" then get proved wrong. The kids were away so I thought I'd put a T-case drop on and my new shocks. I knew the rear shocks were the ones to be worried about but I never have time so I figured why not. I parked in the TSC parking lot and pulled a bolt from my cross member to get a longer one and went to the passengers side rear shock to pull one of them to get a new one. I figured I'd start on that side cause if the bolt is going to snap then it would be the one with the exhaust right by it. I got both bolts out with no problem so I thought Hey might as well pull the other side too and just swap the shocks in the parking lot. The first bolt on the drivers side snapped off right away! I didn't touch the second one. I was pretty mad but expected it. I went in and bought a punch and a hammer along with my new hardware and came back out to try to punch the nut out. I couldn't get it out after 10 minutes and a sore finger, it's tight in there, so I gave up. I figured I might as well throw the one shock on and I'll come back to the other later. When I went to take the bottom nut off the stud it snapped off on the passengers side! I had taken that nut off last year when I put on my lift with no problem I don't understand how one year makes a difference. It's not like its a nut that hasn't been touched since 93. So now I have no passenger side shock and the driver's side is missing one top bolt.
I moved on to the T-case drop. It was a pain in the arse to get the stud out and when I went to get my 15mm wrench it was MIA. Back into TSC and picked up a pack of ratcheting wrenches. After fighting with them I got them out. I started with the Passengers side first and them the drivers side. I don't understand why but the drivers side the crossmember pulled forward and out so I had to get 3 ratchet straps to muscle it back to where I could get the bolts in. That was a PITA. Got the new bolts threaded in and grabbed my new 15mm wrench I just bought and it was too small. Alright bigger head thats cool. I grabbed the pack I just bought and it goes from 15 to 19. WTF happened to 16, 17, and 18? I guess they didn't think it was important enough to include it in their set and I was too stupid to look first. I already used it so I personally can't return it. Got a 17mm socket and finished the TC drop. Got out from under the Jeep and lit up a cigarette and noticed that all the cars are gone. It was almost 5pm and the kids were going to be home soon so I had to take off with two messed up shocks. It isn't noticeable but does worry me. The TC drop made a nice difference. I didn't think I needed it at 3" but I'm hopping to go up to 4.5" when I find more time so I figured I'd put that on first.

Sorry for the ramble. I just cant believe I spent that long on nothing. If you've read this far here's my questions. Where can I buy the studs for the shocks. I've seen them before, the ones that have a threaded section on both sides. One goes into the shock mount and gets bolted in and the other side is the stud.
How can I press the broken stud out? And does anyone have an air hammer they could knock the upper bolt(s) out with? I'd rather try to fish a nut in there then cut up my floors.

Technical Advice and Questions / Junkyard Shocks for an Xj?

« on: March 24, 2009, 04:48:48 pm »

Has anyone used shocks from a different vehicle on their Xj with a 4.5" lift? I'm getting coils soon and need shocks. I'm broke and the JY charges $7 a shock.

Technical Advice and Questions / Dana 30 ?'s Please help

« on: March 21, 2009, 02:12:07 am »

I'm thinking of swapping my D30 in my 93 sport for my brothers D30 from a 97 grand laredo. My jeep is making a weird vibe during a slow turn and sometimes feels like its binding some. I figure swapping the axles would be an upgrade for the U-joints and maybe his wont be in as bad of shape.
Questions
-Are the unit bearings and the breaks the same. If I could unbolt my caliper and put it on the new axle I wouldn't have to bleed the brakes and could save myself some time.
-Am I missing anything. I have been told the Zj axle will fit in the Xj. I'm assuming I'll just have to unbolt the control arms, Drive shaft, shocks, and calipers. Swap axles and bolt everything back up.
-Would it be easier to swap just the shafts? Do you have to change the axle seal when you change the shafts? If I have to pull the carrier do you have to mark the R&P so the same teeth match back up? I haven't heard if you do, and if you do how? Are the unit bearings the same? I don't have a 36mm socket right now and it would be quicker to swap bearing with the shafts anyways.
-I was leaning towards swapping axles because I didn't know if the ball joints could be bad, how do you check for certain? I had the wheels jacked up and was tugging and twisting on them and they felt solid and I watched the knuckles as I jacked them up and the wheel didn't drop at all and I couldn't lift up on it on the jack stands.
Thanks for any help. I did search but didn't find enough info to make me comfortable enough to just start tearing into my DD. If there is info on this that I missed please point me towards it. I've read Go jeep's and MadXj's write up on changing axle shafts and seals, and doing ball joints. I have yet to do anything like that, and don't have much cash to get new hubs and ball joints so I'm trying to use what I got.
