What size dock washer, and what size bolt? "2 1/2 inch" is not a size, it's a length.

Isn't the Jeep 4.7L a hemi engine? But I don't know if the 4.7L would fit in an MJ -- and having owned a WJ with the 4.7L, I hope I never ever own a second one. Stroker ...

Much cheaper than any V8 conversion would be a cam and a set of sightly larger injectors. http://comancheclub.com/topic/17726-drag-comanche/ https://www.allpar.com/trucks/jeep/comanche.html

Yes.

Then what's the coolant temperature sensor on the left side of the block for?

Sylvania Xtravision are not "high dollar" replacements. They are the same power as stock on high beam, but more power on low beam, and they have a better distribution. When I bought a used 2001 XJ the factory headlights were like two piss holes in the snow. I replaced them with a pair of Xtravisions and those give me all the light I need. Plus they are rated for something like twice the life of OEM, and abut four times the life of the Silverstars.

This is very interesting, considering that there was no shortbed Comanche in the 1986 model year. The shortbed first appeared in 1987. Fuzzy recollection is that the 1986 16-gallon tank is the same size as the larger longbed tank, with an internal restrictor to limit capacity.

The cross-over point is approximately 165 degrees. But that's approximate. You can probably get by with a 180 degree thermostst, but the engine was designed to run with a 195. I can't think of a single valid reason to NOT run what the factory has determined through extensive testing to be the best choice.

Unless he gets an axle that doesn't include calipers, and then tries to use his existing calipers.

Don't forget the hubs/brakes compatibility issue.

Large reservoir feeds the front.

The aux fan relays on my '88 XJ and my '88 MJ are on the inner driver's fender, right next to the airbox. Yeah, thanks...I don't have those. my AUX fan relay is in my PDC. So how do I verify the AUX fan is switching on when it is suppose to? My bad. I went away, and when I came back I forgot we had switched from discussing a '90 to a '92. Hornbrod is the man for HO stuff.

I don't think you understand. The XJ and the MJ are set up with two SETS of cross member mounting locations. Whichever one is used, there is one stud and one threaded hole for a bolt. There is another set of mounting holes, forward or rearward of what you are currently using. This is to account for differences between engines and transmissions.

Three inches off longitudinally, or laterally? Are you aware that the XJ and MJ have two sets of mounting holes/studs in the frame rails for the cross member? Perhaps you need to relocate to the other set of mounting holes/studs.

Which terminal in the relay socket did you test? Remember -- a relay is an electrically controlled switch. For the relay to be "ON" there has to be 12 volts to the input of the control side (terminal 85 or 86), and 12 volts to the input of the load side (terminal 30).

The discussion in this thread was about a '90 MJ -- that was a Renix design, with AMC/Renault electrics. Your '92 has a completely different wiring system, designed by Chrysler. On the '87-'90 Renix system, the aux fan is controlled by a temperature switch in the driver's side radiator tank, which sends a signal to a relay on the driver's side inner fender, which in turn controls the fan. There's a second feed from the A/C circuit that turns on the fan when the A/C is operating. On the HO models, the temperature sender is located in the thermostat housing rather than the radiator tank. The sender transmits a signal to the ECU, and the fan is controlled by the ECU. I don't know if the HO aux fan has a relay.

In internet lingo, It stands for "Cool Story Bro" :yes: That's the problem. Just about all home-brewed acronyms today have multiple meanings. When you want people to understand the question and provide meaningful answers, it's better to just use words, despite their being so last year. This is an Internet forum, not a text message. There isn't a 256 character limit to posts.

Good catch I went SOA so I ditched the stock spring plates But you didn't have to. You could have just flipped them from one side to the other and reused them. That would also have allowed you to keep the same shock absorbers.

"csb" meaning "Chevy Small Block"?

Probably not. Axle tube - 2.75" Perch offset - .5" x 2 Spring pack thickness - 1.25" Total - 5" I don't see how it can be any less than that.

But you'd need to take the front axle out to get access to the needle fitting. It's easier to just grease it well when you install it, then replace the zerk fitting with the supplied plug.

Also check the coolant level. When the level gets down (and it doesn't have to be very much down), coolant doesn't get to the heater core.

This is for a 1990 MJ, per your signature? Hornbrod is a post-90 owner, and that page looks like a page out of a Chrysler-era FSM, not an AMC manual. It's entirely possible that the wire colors changed from the AMC models to the Chrysler models, and the entire schematic of the headlight delay module may have changed, as well.

Sounds like there may be a new master cylinder in your future.
