BIOTEX reponded: Not at all. Just means the slave cylinder is leaking and not the master cylinder. On a side note: You should have seen the strange look my Aunt gave me the other day when I mentiond needing to "bleed the slave after changing the master". I kid you not she was puzzled and bothered enough to pull me aside to explain myself.

Losing as in leaking out or not sealing?

89 MJ 4.0 5 speed 75K miles 3 or 4 days ago the clutch pedal did not come all the way up. Previously the pedal would come all the way up and would not engage until it was most of the way up. Now it engages closer to the floor. It performs just as well as it did before. It has not gotten worse. It was not a gradual change. What happened?

Any best guess which years have liners?

What are your thoughts about foam liner or not. I would think the foam has disintegrated after 30 years but would provide some proofing if there. Curious that the progression was away from foam. Your pulling only the wires needed from the donor harness and not disturbing the others makes a lot of sense. The install will be for an 89 4.0. 5 speed. The controls will be by cables to the dash and not electric? If the dash controls have to come out of a junker I wonder how well 30 year old cables and controls will work.

So the box is actually two parts? Junk yard would probably want the same money for both parts as just one. Do you know if a diff wiring harness is needed and if so will that have to come from a junker also?

Vineyard, Kalispel's winters are tough. The pics you posted on June 9 suggest the MJ was kept out of the weather and out of the sun.Body and chrome look flawless. Red interiors fade the worst. Curiously, your seat covers and dash are not. Both original? You should post pics with your profile.

I think you are very, very right! If you are willing, have a look at the following link. Both my MJ's are 4.0 5 speeds. An 87 and an 89. Part of the middle of the thread is for 2.5s which is not relevant for me. Member 835 appears to have had knowledge and experience but it he both joined and last visited CC in 2011. Notice the pics posted by Comanchmodder on June 20, 2014. He last visited CC in 2015. Has anyone out there actually done this? If so, please comment on the need for changing the wiring harness, which I assume is not available new? Does anyone know if the dashboard controls are available new?

The parts manual suggest the information I have gleaned from past threads is wrong. Unkown is what is needed about wiring harness. Is that an OEM parts manual that is online?

I do not know if the dashboard controls are available new or not. If anyone knows, please share the knowledge. All the ac hardware is easily available.

I think there is an old thread on CC showing the MJ evaporator not fitting in the replacement XJ box

There is some protrusion on the MJ evaporator that will not fit in the XJ box. In some thread here, there is some discussion about using an XJ box and using an XJ evaporator. I don't know if that works out or not. I would prefer to find a MJ box if that is doable.

My understanding is that if the MJ never had ac, the box is only large enough to hold the heater core. If the MJ did have ac in the beginning, the box was larger and big enough to hold the heater core and the evaporator core. I had a total replacement done this summer on an 87 MJ that did have ac in the beginning. The mechanic on advice of the supplier installed an oversized MJ evaporator and a new heater core in the existing MJ box without a problem. I want to have ac installed on an 89 MJ that never had ac. That box is not available new. I have not found one used and neither has the mechanic. Although there are fewer MJs left in the junk yards that have not been stripped, I wouldn't think that box would be a highly sought out item anyway.

I can not locate a box that holds the ac evaporator and the heater core. Not a new topic. Does anyone know where one can be found? The XJ box is different. It will have to come out of a junker but they don't seem to be available from here to Jesus.

Eagle and Keya, those were some powerful face ups to the monster. Good job.

Many thanks

You attached it directly to the metal of the roof? Won't the heat of summer sun fry any sticky adhesive? Any pics?

Very small print, Minu: Once because I screwed up putting it in, once to sound deaden the roof, and again to pull wiring for an overhead console... just in case. How did you deaden the roof? Any pics?

Keya, that took grit and determination for sure. Glad you dealt with it early on. Now make sure the Alabama bad boy doesn't fall off that particular wagon. A thread of personal accountability going on here.

saveevryip1998. I thank you for the kind offer but with shipping and thus and such, I would likely spend what I might pay an upholsterer to do it all. I probably will do that but have fielded suggestions for what might work the best. Great moniker. Many thanks.

I have been living a sheltered life. Connections beyond the Milkyway and a cache of MJ tail lights. Wow Any suggestions?

Could it be used to wipe rust from chrome rims without having to set up an immersion bath? Some tube vid showed using aluminum foil to clean rust from chrome rims. Have not tried that but I have doubts about how well that would work. Your XJ looks to have oversized tires. You lifted it? How much?

That is pretty amazing vid. $80,000 would not be beyond what a body shop could afford. Looks like a pretty clean process and removes paint too. That was pretty ballzy for him to place his hand in front of the lazer. Wonder if it rearranges his DNA. Technology will bring the price down. Thanks for the input. Time for a GoFundMe page? DirtyComanche. Thanks for the green thoughts. Rust is as natural as you can get. Iron is used in agricultural processes and iron is in your vitamin pills. Obviously much smaller quantities. Breathing the dust from sanding poses a bigger risk which you protect against. The container states that one cup should be used for a load of laundry. Less is used by the guy who restored the parts in the pics that are shown. Laundry detergent used to be a big polluter to rivers and streams because the phosphates used in the past would not break down. Recall seeing foam and bubbles along a river's edge? That was often the results of phosphates from laundry detergents finding their way into the rivers. I see you are from Canada. Gotta question for you: Some of the Jeeps I see online from northern US states are major rust buckets. Do you drive your Jeeps in winter? Fire departments wipe down the underside of fire trucks after every run. Are you doing anything like that once a month or so? PC06. I see ice on the ground around your tank. I assume the chemical process is not impeded by low ambient temperatures. Have you used it on a chrome finish that has some rust coming through? A chrome rim for example. JeepDriver. Are you doing your own chrome plating? If not, what are you plating the items with? By reversing the process, are you connecting the current so that your desired object is the anode? Are you suspending the plate material in the bath?

In the 60s my Dad raised tobacco. I worked in it some in my early and mid teens. Nasty stuff. Worms about the size of your ring finger would eat holes in the leaves. The plants were sprayed with insecticide. One day around age 14, I read what was printed on the bag of the dry contents that would be mixed with water. More than 50 years later I rember what was printed: Arsenic Lead. When the bag is empty, burn the bag and bury the residue.
