How did your brakes feel before you replaced the front lines? They were getting spongy (old soft lines and a pin hole leak in the FL hard line) Did you bleed everything (including rear) until new fluid came out? Yup, the system was been flushed until clean. Did you bleed them in the order you listed them? (RR, RL, FR and FL) Yes How firm does the pedal get with the engine off? If it just feels as it normally does when running, it's not enough. It should be stiff enough you can barely push it down with the engine off. The pedal is firm when the engine is off but once it is running, the go to the floor pretty easily.

Were your brakes soft with the engine off, on or both?

I replaced the front hard and soft lines and flushed new fluid through the system. The brakes are strong until the engine is running. I did a search and read about bleeding the master cylinder. I made hard lines to loop from the outlets back into each compartment. Pumped the brakes until no air came out, connected the master back to the prop block and bled all 4 points again (RR, RL, FR and FL). I still have no brakes with the engine on. Did I miss a step or is there something else going on? (BTW, I checked for fluid leaks all around and fixed one on the bottom side of the prop block and bled again) Any ideas? :mad: **edit** We pulled the master cylinder while changing the lines because we could access some of the fittings. I reinstalled it just as it came off.

Glad to find another CC member on Hearth.com. The build is looking good. Where did you get a $25 tool box for the bed?

Was it seasoned or green wood? Man, that's a lot of wood. Did you use any helper springs or air bags?

Here's my truck hauling a 1/3 of a cord: It handled better than I thought it would. Need to add some airbags in the back but it did well with out.

I'm replacing the idler pulley when I get home and hopefully hitting the JY this weekend.

The front bolt was loose. The idle is much better now. I should have thought about that. My old Honda CB350 had bad leaks around the intake boots. :doh: I got wrapped up in the idea of a vacuum line issue. Thanks guys! :bowdown: A few test laps around the neighborhood and it's running well. Now I can get back to the wiring issues!

On another thread: http://www.comancheclub.com/forums/viewtopic.php?f=2&t=21523&p=222210#p222210, I thought I had found a vacuum leak at the brake booster. I plugged the vacuum line today (and replaced the check valve) but the engine is still idling high. I cleaned the IAC sensor and the throttle body, so I don't think those aren't the issue. Is there another vacuum line to check? :hmm:

I've got a grocery list for the Junk Yard now! Looks like I"ll pick up a '95 ZJ box while I'm getting the XJ steering box. Thanks for all the help! :D

You can turn the steering wheel side to side w/o getting movement from the wheels.

Thanks guys! Looks like I'll be swapping in the double diaphragm booster once ye olde tax check comes in. A new booster and rotors/pads should greatly improve my stopping ability! While I'm under there might as well track down the cause of the play in my steering wheel. Do you think a junkyard booster is a safe bet or should I go with a remanufactured one? This board is a life saver, you guys are packed full of great info. I've been on other auto/bike boards and found a lot of people that weren't very helpful or had the "if you have to ask, you shouldn't be doing it" attitude.

Bingo! Thanks for the tip! Looks like I'll be getting a new booster. Is there any (like off a ZJ) that would be an "upgrade"? After I found that plugged line, I decided to check all the vacuum lines once the weather gets a bit warmer. Little too frosty to be yanking on rubber hoses in my unheated garage.

My truck was idling pretty high (not sure of the rpm, no tach), so I searched the forum and found the info on cleaning the IAC. Cleaned up the sensor, cleaned the passage and gave the throttle body a good bath. It's still idling high. Bad IAC valve or maybe a vacuum leak? The RPMs increase when I press on the brake pedal. I found a plugged vacuum line going from the EGR to a metal disk shaped doohickey that is attached to the driver side below the top of the throttle body.

I'll put new problems in a new post, sorry about that! Used to doing updates like that on a motorcycle forum. Looks like I'll pick up some bulbs and sockets and see if that solves the remaining issues. Thanks for all help! At least it's on the road in time for the snow. :D

Thanks WildMan! I figured most of them were matching color to color but the heavy red and grn/blk were making me hesitant. I'm assuming that the red went into the old connector, that way if you had fog lights from the factory, they just plugged the fog light harness in and you have working fog lights. I have a soldering iron at home, never used it. I think it's time to learn. I'm not a complete noob to wiring, did some major repairs on my old CB450. But I'm more hesitant with the more complex wiring on cars.

I picked up my MJ on Saturday and noticed the marker lights and front signals didn't work. The headlights also seemed pretty dim. Today, I took off the front clip and found the issue. The wiring connector from the main harness to the front section is rotten. Most of the wires were broken off of the connector at the harness side. The connector isn't salvageable, so I snipped it off. I have enough slack on both sides to connect the wires but since they were broken off and corroded I can't match them up. Here's what I have: From the main harness side: -Heavy gauge (8ga?) red -Green/Black -White -Green -Brown -Gray/Black -Dark Blue Front wiring section: -White -Black -Dark Blue -Gray/Black -Green -Brown The heavy gauge red wire is what's throwing me for a loop. Anyone know the proper wiring connections? I looked through my electrical service manual and I don't see this connector shown. ***UPDATE*** The side marker lights are now working, the signals are sluggish and the indicators on the gauge cluster are constantly on. The parking light filament in the turn signals isn't working either.

Under a grand. ;)

The midwest... Der. :rotfl2: Rob L. Central Indiana, it's not your old MJ is it?

Just brought it home today :yes: : 1988 LB 4x4 I6 AT

Thanks everyone. @Dakal, I love that shirt. Still need to order one. Here's the pics: Known issues: - rust (rockers and cab corners) and minor body damage (frame is solid) - leaking oil around the distributor cap - warped rotor up front - front marker lights are out - idle is running a bit high (sounds high to me, no tach :( ) - lots of play in the steering wheel The guy cut some off the price since I drove two hours through the crazy snow drifts to come check it out.

I think I have a good idea but I'll gladly take the advice!

New guy here. Going to check out an 88 MJ (I6 LB AT 4X4) tomorrow, hopefully I'll be a happy new owner. I'm not new to Jeeps, I've had an XJ (87) a CJ7 (86) and YJ (??). It's been a few years since I've owned them though. Great site, glad I found it. There's a ton of great info on here! :D
