No need to say it, but I'm new here. Just picked up my first Comanche last week and I love it. The guy I bought it from had 4 of them sitting in his yard. 2 for parts, and 2 to drive. He painted this one himself and I love the color man. It definitely has some issues, but the body and interior are in great shape. I've never driven a 4-speed before.. I can't say I love it but honestly it's not bad. The rear end has some clunking on decel, and according to the seller it's the pinion bearing. It drove fine on the way home after I bought it, but I know I need to fix the rear end asap. 2 days ago it randomly started running rough and misfiring at idle. I did a lot of research on here and I'm so thankful for this community, otherwise I would have wasted a lot more time and money on it than I needed to. I found 2 cracked vacuum lines (one that runs from the throttle-body to the vacuum reservoir, one that runs to the firewall) and after replacing those and doing a basic tune-up it runs fantastic. I still have a lot left to do though as I've found several other issues. Things I've done to it since I bought it Oil Change Plugs, Wires, Cap & Rotor Coolant Temp Sensor (for temp gauge) Serpentine Belt Vacuum Lines Things I need to work on next Rear End - Planning to open her up and see what I need to fix. The Dana 35 appears to be pretty easy to work on from what I've seen. This is going to be the first thing I fix. I have tools to help me get the crush sleeve set and I don't think it will be a problem outside of working the old bearing races out. Universal Joint - After inspecting my rear end I actually found out that the vibrations and knocking were coming from a loose universal joint. Clutch Master and Slave - I was happy to find a few drips of clutch fluid on my floor-mats and noticed that it has been dripping on my fuse box. The master cylinder will have to be replaced. I also noticed what looks like fluid under the transmission. I fear that the internal slave on my AX4 might be leaking too.. This is going to be my least favorite job I think. Rear Main Seal - I doubt this thing has been replaced since 1987. I found a video that shows how to do it without removing the crank, so I am probably going to try that first. I might as well to it at the same time as the slave cylinder, so it's going to be a nice weekend job. Water Pump & Thermostat - There doesnt appear to be anything wrong with these, but I think its safer for me to replace them now before I end up having an issue. It's a reverse rotation water pump from what I've gathered. Valve Cover and Oil Pan Gaskets - I'm going to have to replace the oil pan gasket when I change the rear main, so may as well change the valve cover gaskets too. Front parking lights - these don't work right now. I think a bulb is missing from one side. Not sure about the other. AX4 Output Shaft Seal - Discovered this was leaking while replacing the U-Joint. Horn - The horn button on my wheel does not engage the horn. This could be several things, so Ill have to troubleshoot. After I get these all done I should have a pretty solid truck. I'm really excited. I get a good bit of attention driving her around town. Actually had 2 guys tail me on the way home one day which was fun... I don't know for sure but judging from what I saw I was worried they were going to try to jack the truck Anyways.. Happy to be here! I'll update things as I go. See you guys around! P.S. Vacuum Lines are definitely the first thing people should check if the engine is running rough... Most of you seem to know that already, but I didn't at first.

Hello. I have an 87 SporTruck 4x2 with the gas 2.5L inline 4 and the AX-5 transmission. My clutch fluid was leaking out of the transmission so I pulled the transmission out and replaced the internal clutch slave cylinder. Then I started driving it again and the clutch engagement point was very low, but if I pumped it up, it would move up, so I replaced the clutch master cylinder too. I’ve got everything really nice and tightened down. I bled it once, and then later a second time. Now my clutch engagement point is moving around wildly and I am very concerned. The fluid level in the little plastic reservoir is exactly the same every time I check it, right at the MAX line. Sometimes it is a long and gradual engagement, and sometimes it is a very short and abrupt engagement. Sometimes it is right near the bottom and sometimes it is closer to the top. I looked around and nothing appears to be leaking, but it’s been wet out and it’s hard to tell. The fluid level hasn’t gone down so I guess it’s not that.

What is the part number for an internal throwout bearing (internal slave) for an 89 AX-15? thanks
