Car Forum / Driving, Maintenance, Tuning / 4x4 Cars / April 2006Jeep Cherokee distributor issue
Winter's finally hit us here in Minnesota. When I go to start my '98 Jeep Cherokee (4.0 liter, 100K miles) there's a high pitched wining sound that goes away in 2-3 minutes. I first assumed it was a belt, but then placed my hand on the distributor cap. I felt vibrations there, which went away when the sound went away. Does this sound like the distributor is starting to go? Tonight I took the distributor cap off the Jeep. The cap and rotor looked ok. Then I realized that I didn't take note of the order of the spark plugs! Just kidding -- of course I did. Here's the problem. In order to take out the whole distributor the retaining bolt needs to come out. I found a good reference here (http://members.cox.net/wilsond/distributor/) but he doesn't explain where this bolt is. I've done a fair amount of auto work in the past, and did this on a '79 straight-6 Dodge about a decade ago. (I'm a little rusty, but not a total amateur.) Anyway, I believe I see the retainer bolt but -- aren't engineers brilliant? -- the bolt sits mostly under the distributor itself, with no way to really get a wrench in there, and my sockets are all too tall. Anyone have a suggestion on how to get at the friggin' bolt holding in the distributor? I'm willing to buy a new tool, since doing this job will probably save me $100. Just can't figure out what will do the trick. Thanks. -Paul Bramscher This can be done with a "claw foot" wrench that's basically a very short open end wrench that you put a long extension on and then your ratchet. They come in a set and are sometimes very handy. They also make a distributor wrench made just for that. Also before pulling the distributor make absolutly sure you know where the rotor is pointing and don't turn the engine till the new one is in. You'll also notice that the bolt fits between two fingers on the distributor and keeps it from turning. JoBo > Winter's finally hit us here in Minnesota.

Now that I recall, I did this on an old Dodge Diplomat when replacing the head gasket. I had the top half of the engine pretty cleared away and didn't have any problems getting at the distributor. I priced the job out at a mechanic this morning, doing it myself will save $150. The guy here (http://members.cox.net/wilsond/distributor/) wants you to mark the direction of the rotor twice. One before you pull it (straight out), and again after it's done rotating as it comes out. This way, you rotate it to position before you put it in, it spins, then should be at the original mark when you re-attach the retaining bolt. It's been 10+ years since I did this. That sound about right? Two marks make it a little easier? > This can be done with a "claw foot" wrench that's basically a very short > open end wrench that you put a long extension on and then your ratchet.

You can forgo the second on if you want but will require trial and error to get the right tooth. Sean 78 cj 304 t400 quadracrap..er trac. > Thanks for the help (both replies).

You can pick up a distributor wrench at your local auto parts store. This is a box end wrench that has a bend so it will go under the dist. base and reach the bolt. They are pretty cheap. Around 15 dollars. > Winter's finally hit us here in Minnesota.

The dist. shaft bushings get dry and the dist. makes a high pitched squeal or wine. You can test it by spraying penetrating oil down the shaft into the bushing. This is a temp fix to confirm the problem. Or remove dist. remove the plug on the side of the dist.. Push grease in the hole, and silicone seal the hole closed. Try this before replacing the dist. > Winter's finally hit us here in Minnesota.

I am 54 years old and cannot remember having had another distributor go bad. I can't even remember a friend who had a distributor go bad. That Dodge product was the worst vehicle we ever had. Poor mileage, ate manual transmissions, leaky in the rain, hard to get parts for (and expensive), poor handling on the highway, too many blind spots. The worst was that although the heater could melt the boots right off your feet you sit in a one layer thick, un insulated tin can and you can see your breath most days all winter long. Barely had enough power to defrost it's own windshield. Can't remember how I changed it but the job was done in the driveway since the 35 mile tow job is too expensive to suit me. - Regards Gordie Engineers should be forced to work on some of the crap we produce! You probably found the right bolt - forward and toward the block from the distributor. I think I was able to get mine out with a wobble extension and a short set of 1/4 inch sockets I have, but it may have been one of those "get a short wrench on it and grunt" deals. I've have the bushings go in a couple of distributors over the years, but not often. Usually, the GM ones just keep getting sloppier over time. Anyway, once you get hold of the bolt, it attaches a hold down shoe. Remove the bolt and shoe, then the distributor pulls straight out. Thinking back, the hard part was getting that @#$% bolt back in. I put in in the hole in the clamp shoe then used that to get it positioned. PITA, for sure. At least you don't have to mess with it to adjust timing, but watch replacing the distributor - it's common to get it in one tooth off on the drive gear and the computer can't adjust the timing that way. > >Winter's finally hit us here in Minnesota.
