SHeadrick Started the lift process. Got all the old out and got the new arms in. Waiting on a new bolt for the track bar. Should have the rear done next weekend.

KiloWatts Got the Rancho RS5000s on. Turns out my excessive lean and body roll was due to my worn out Bilstein 4600s. I only got 3 years out of those things before they started bouncing out of control. Kind of surprising since they have such a good reputation around here. These new Ranchos, I don't think they're bad at all so far. We'll see how long they last.

Helps if you have the car parked on a surface that is nose up too.

Also when the motor is dead cold, start it up and squeeze the upper hose it shouldn’t pressurize very quickly. If it does you could have a head gasket leak or a cracked head introducing combustion gasses into the cooling system (pressurizing the system). This will both overheat it and introduce air bubbles.
Should have bought one of the spill free funnels awhile ago, it's quite handy.

Pretty sure I got a at least a little bit of air out of the system and it wasn't just cavitation, but I'm still running much hotter than I was a week ago for whatever reason.

Don't think I have a head gasket leak, as it took a solid amount of time for the upper radiator hose to pressurize.

I should get the new radiator tomorrow, so I'll get that thrown in along with the new hoses from Napa I bought and hopefully that'll put things back to normal; if not, I'm not sure where to go. It's still stumping me that this happened right after the battery cable change over; I can't imagine how that would have affected the cooling system, but it is quite a coincidence.

I guess if none of this works, I'll pull everything out again, leaving the pump on and try to flush the system with the garden hose.

Looks cool for a fussy 6 attempt, and thanks for the hints.

Wife and I are still trying to find the perfect fabric to redo ours. We want something camoish and bigfooty.

This is getting a hard look, but doesn't come in the width needed.

This is another good one.

Headliner

Old headliner was falling in my face; So off to Joann Fabrics.

Found some brown decorative fabric at $20yd bought 3yd strip and a 1yd remnant, along with spray glue with Pro waterproof qualities. Cost me around $100 all said and done.

Pulled the fiberglass / foam / something down. Screws and plastic pop rivets along with sliding down the B pillar covers.

Scraped clean the old foam and really thin tan headliner fabric with a steel brush.

One thing I leaned for next time. Leave more overhang at the edges and center the new stuff. Trim and glue the overlap it will look a lot neater for the extra effort. I would also add to the shopping list a can of liquid contact cement just for the edges. First time mistake, I'll do better next time.
Work in the shade so the glue doesn't dry at warp speed. Also have a friend to help streatch the new fabric to avoid creases. My second mistake, bring friend and Beer.

Plan a day or at least a long morning its time consuming in detail but not hard.

Anyway its done, next project. ECU failure to charging system.

KiloWatts Finally installed my front bump stops by squeezing them through the springs. I don't know why I waited so long, that was probably the easiest freaking thing I've ever done to my Jeep.

You can wiggle test the PCM or press on it while the engine is running to confirm solder issues. If you're good with a soldering iron you can reflow the joints and the header, which is usually where the problem lies. I preferred to do it this way instead of playing remanufactured roulette. There's a bunch of info in this thread, item #2:

BeardyHat I think I've got a good idea of what might be happening with my sudden over heating. I checked out my cooling system this morning and was able to squeeze some air out of the system, so I've got air getting in somewhere. Which is also consistent with the temp spikes I was seeing and the boiling coolant in my reserve tank.

I'm thinking it's probably either the cheap Amazon hoses I put on (which don't quite fit perfectly. There's a small gap on the upper radiator hose) or maybe I put a hole in my radiator out on the trail; but I'm leaning towards hoses.

Did fix the brake light problems with new switch at steering column.



Replaced the HVAC control unit, climate control resistor with wiring harness and the blower motor. Don't know if that will fix the rest of the a/c problems but should if I don't have any leaks? Previous owner had by-passed the climate control resistor and HVAC control unit and wired a toggle switch into the dash to get the blower motor to push air. Replacing the bad parts have gotten rid of the rats nest of rigged wiring under the passenger dash, at least for now. I may have to search for another wrecked '98 ZJ, as it doesnt have a lot of parts left on it.



I hope that after the ECU is replaced, that that gets me a engine that stays running so i can start the 4" Rough Country lift with all new tie-rod ends on the front. I have had this Jeep for nearly three weeks and its been either setting at the house being worked on or at the mechanics. I knew it had issues when i bought it, mainly electrical and A/C, so I expected to put some money into her up front. I just hate running down electrical issues, as it feels sometime like you just chase false leads mostly. Once ECU is replaced their won't be many engine ghosts left, at least that's my wish. It has an after market stereo just setting in the hole where the factory one was. I have not looked to see if the radio harness is intact or butchered, may just pull a radio out of another wrecked ZJ to fill the hole if I can't secure the aftermarket one in the dash, but that is not a priority on this build.

Thank you for sharing your thoughts Timo [emoji106]

This is what I'm hoping to do with my RWD.

BeardyHat Something is afoot with my cooling system. Took the Jeep back out when it had cooled down to 84* outside, which it should have no trouble with, but within five minutes of driving, my temps shot up to 240*.

I've already ordered a new radiator, so we'll see what happens when I change that, but I'm wondering what the hell may have happened. I took the Jeep wheeling last weekend and all was fine, it sat for a week, I changed the battery cables and now it's overheating. Could something have been knocked loose in the radiator/cooling system and laid dormant until now or could I have messed up a sensor/fuse or something to have caused this?

The ZJs cooling system is all mechanical, right? So odds are, it's probably not a sensor issue?
