WRONG! concrete blocks can fail suddenly and totally. Wood blocks do not fail in the same sudden way. A concrete block failure can kill you, not so with wood blocks. Sorry forgot to use the sarcastic font. Yep wood is fine I use wood blocks to hold up equipment that weigh 35 tons.

Get that guy some concrete blocks STAT!!!!!

if they're stripped i'm lookin for more of a rounded tooth right? i'm hopin that's all it is, but yet again, i got a rusty one in my room just incase that one's trash and it goes all the way down, Redwolf If the teeth are stripped you will have a few good teeth on each end to look at for comparison. The teeth should look the same all the way across. It may be gummed up but this is a common problem to strip out. I think jeep had a recall or service information on this back in the day.

I would guess so. I think the connection on the tcase is the same.

Advance Auto parts PN.03269 $21.99 I put one in my 88 a few months back and it fit fine. This is the one piece no cruse control that goes from the speedo all the way to the trans or t-case. Its weird they only list it for certain year Cherokees not under any Comanches.

It could be the control arm bushings. Always tighten the control arms with weight on the tires.

don't wory about the questions we all are here for the same reasons. To do a spring over you must weld the new perches on. If you can remove the axle and do the prep work your self ( gringing off the old perches, and locating the new ones) you could probably get a shop to weld it together fairly cheap. A muffler shop can probably do it.

What do your new brackets look like?

They look the same. I use photobucket but can't remember my password it has been a long time.

I am having trouble loading a picture of my control arms but I'm sure someone will chime in and confirm what you have.

I think those are the factory mounts not a drop bracket. I will go out and look at my truck in a few.

What are we looking at?

Do you mean the control arm drop brackets? If so you should be fine with the adjustable control arms. I believe the control arm drop brackets are only if you use the stock arms with the lift.

I think 90 4.0 still used a closed cooling system . On the closed system the tank is under pressure.

If tank is cracked it can't hold any pressure and the water will boil. Pressurizing the water raises the boiling point. I would fix the tank first and then see what happens it may be thst the taink just failed. It happens.

What you have just described doesn't say anything about a "ratio." Up is up, down is down. What "ratio"? Do you understand that shocks have internal valves to control the fluid flow and velocity? That's what allows the shocks to do their job -- they restrict the flow of the hydraulic fluid, which restricts the movement of the suspension. Valving can be set to 50/50, which offers equal resistance to compression and extension, or it can be set to other ratios such as 60/40 or even (as in the drag race shocks) 90/10. Take a 90/10 shock and mount it upside down, and now you have a 10/90 shock. Instead of allowing a lot of extension but little compression, it will now resist uplift, but if the front gets extended it will offer almost no resistance to compression. And that still doesn't address the fact that some valves may be designed to operate in one orientation only, and won't operate properly when installed upside-down. I understand the valving and understand that not all shocks can be mounted in both directions but some can. And I am not talking about the op shocks. I just posted a link that explains different shocks that I thought may help. My question about the ratio changing my not have been clear. In my mind if I look at a 90/10 drag shock lots of extension verry little compression. If this shock is of a style that can be mounted in both directions the ratio will not change because its always extending when the car launches no matter the orientation. Now if you put the shocks on the back of the car that would cause a problem. Or I could be nuts sorry I took it off topic.

Some how the quote got ran together sorry don't know how I did thsat. Lol

Since the shocks operate with gas, not fluid like the Oleos on an F/A18 Super Hornet I can't imagine why orientation would matter but I'm all ears. The shocks operate with gas, not fluid? What kind of shocks do you have? I don't think you understand what the term "gas shocks" means. Generally, all it means is that, instead of the non-fluid part of the interior of the shock being at atmospheric pressure, there is a chamber that is filled with a LOW pressure charge of inert gas, usually nitrogen. The gas doesn't do anything as far as absorbing shock. All it does is reduce the tendency of the hydraulic fluid to foam when it gets hot and works hard by raising the ambient pressure to which the fluid is exposed. It's like taking a new bottle of cola and shaking it. As long as you don't open the cap, whatever pressure is in the bottle doesn't allow the carbonation gas to foam out. Open the cap, and you get LOTS of foam. We don't want foam in our shock absorbers. The fluid in a shock absorber absorbs shocks by being forced through orifices and valves inside the shock. Not all shocks are designed and valved to resist movement equally in both directions. An extreme example is the 90/10 shocks used in the front of drag race cars. They allow lots of uplift, to help transfer weight to the rear wheels off the line, and they resist compression to help KEEP that weight on the rear wheels. Consider what would happen if they were mounted upside down. Also consider that the valves in the shocks are designed to function when the shock is installed in the orientation the designer expects it to be installed. If you invert the shock, the valving may or may not (probably not) function as designed. Here is a link to monroe that explains a lot. http://www.monroe.com/en-US/support/Technical-Training/Shock-Absorbers/ And when talking about mounting a shock upside down and changing the compression or damping I am confused. Here is my thinking... Install shock raise axle shock compresses. Remove and reinstall shock upside down raise axle and shock compresses. It seems to me the ratio would not change or am I not getting it?

Doesnt look like too bad a deal. http://charlotte.craigslist.org/pts/3997646488.html

Auto zone has the resistor for 33.99 part number 20118. I have used this one with no problems. They also show one for 21.99 part number MT1814 I'm not sure what the difference is. Much better than $74.00

You said you just changed the oil. Is the filter leaking?

I don't think your ever going to get maximum MPG as long as you have vacuum leaks. I am sure someone can help with diagrams. Is it the 89 4.0?

Do you still have vacuum leaks?
