Crank Position Sensor. It mount on to the top of the trans bell housing. It scans the flywheel for the position of the engine crank. It tells the engine lots of important info, like when to send a spark to the plugs. I ve had to replace two through the years. Looks like http://www.ebay.com/itm/SMP-STANDARD-PC87T-Crankshaft-Position-Sensor-Distributor-Pick-Up-Assy-/271236282803?pt=Motors_Car_Truck_Parts_Accessories&fits=Year%3A1987%7CMake%3AJeep%7CModel%3ACherokee&hash=item3f26f139b3&vxp=mtr#ht_1136wt_930

Does it crank but not fire up? Try the CPS. My $0.02

Sunday for me.

I did not know they came with a v6. I remember the v6 was an '86 option only . Was the engine changed?

An article in our local rag, Frederick News Post, about the magic of duck tape. http://www.fredericknewspost.com/your_life/life_news_collection/human_interest/article_e682b43e-a00a-53ca-8688-260553ffd2bd.html

Those things double as coffins.

Harmonic balancer??? Replaced and fixed the squeek.

My Jeep VIN decoder sheet says the first 7 (74GT) is a "Comanche X (Std Payload)"

From what I have read, the shorty was intro'd in '87. See http://www.comanchemj.1hwy.com/photo6.html about 1/2 way down page

I thought the '86 were only the long beds. The short beds were not introduced until '87. The OP says he has an '86.

U-joimts? I had DW on a 91 XJ. Got 'em replaced; problem gone. My $.02

There should be a law against that!

Like the old joke: How do you get to Carnaige Hall? Practice, practice, practice.

In '89, Jeep switched from the BA10 to the AX15, so you have an early model year MJ. The AX15 was used in just about all Jeeps with the 4.0 engines. I am not sure when they stopped using it. If you are looking to up grade, look for a '96 or later model TJ or XJ. That was when Jeep switched to external slave cylinder. If you find one, be sure to get EVERYTHING! including the bell housing, and the internal parts, and the cross member under the trans. The cross member is diff from the BA10. Also, you will need the transfer case (assuming 4WD), since the spline count is diff from the BA to AX. Simply put, "everything bell housing to the trans case."

I am no authority, but I have been told by an "authority" to use Penzoil SyncroMesh for my BA10. (That authority was the transmission shop that serviced my trans.)

I have it on my calander. Hopefully my truck will be ready by then. It is still in the body shop. They are taking way too long. Then everything needs to go back in.

Grizzzz, the panels aren't cheap and the shipping just about equaled the cost of the panel. He is near Toledo OH. So if you are close to that, you could pick up.

I purchased a bed side panel from Z&M Jeep. Call for Zack after 6 edt. http://stores.zmjeeps.com/StoreFront.bok

Sounds like you just need to replace a bulb.

Where is Fair Hill, MD?

The two single socket connector are for illumination. They hold small lights and twist in to the respective dash switches. I believe the other two are for fog lamps (C176) and for Power Comfort Switch (C261). The Pwr Comf were not available on the MJ. So, it just hangs loose with the respective illimination plug. EDIT: The wire colors are from the 88 electrical manual The illuminators have an orange w/blk and black wires. C176 Fog lights have light green, light green w/ blk and black. C261 Pwr/Comf have black/yellow, tan, and black.

PepBoys has a free loaner program. You have to put a deposit down that equals the cost of the item. You have 5 to 7 days to return it. You then get a full refund. I believe other auto shop have similar loaner programs.

Get a lock plate spring compressor while you're at it. That was included in the free loaner toll set.
