  1. I just did some searching on Rockauto. Of the front bearing hubs that listed specs, they all listed a wheel pilot diameter of 71.4mm (or 2.81"). This was looking at a 2003 4cyl. This was for both with or without antilock brakes. Where did you get the 67mm wheel pilot info?
  2. I can get a pic of mine later. You aren't going to get a steering wheel off a junkyard vehicle without a puller. At least I've never had it happen. If a steering wheel has been off and on multiple times, it might get loose enough to come off by hand. I had a Chevy like that. Not an issue, splines were still good and the nut held it on. If the nut has been on and off multiple times, a little loctite might be a good idea. Most FSMs will say replace the nut every time, like a pinion nut.
  3. I mentioned earlier that the replacement for the 900s and 800s is the 7ton (MTVR). On 1 August 2009, we were on the return leg of a Combat Logistics Patrol traveling from Nowzad to Camp Leatherneck, Afghanistan. A 7ton hauling an EET (engineer equipment trailer) was struck by an IED, but it was the trailer that set it off. This initiated an enemy mortar attack on the convoy. After the mortar team was located and suppressed, we started the recovery of the down vehicle, normally a tedious process. In this case the truck was still good to go, so we pushed ahead about 10 km to distance oursel
  4. Just realized I wrote the second set of dates wrong, should have been Jan-Jul 94, so it would have been close.
  5. One Saturday in the Fall of 1990, me and four other guys were snatched up for a Saturday working party. I was sulking about working on a Saturday until I found out we were driving five M813s from Camp Lejeune up to Morehead City, NC to be loaded on ship headed for Desert Shield/Storm. It was just the five of us driving five trucks, no a-drivers, following the SSgt in a M1009 (K5 Blazer). And when we saw the trucks, the cab canvases were removed and stored. It was an awesome Saturday.
  6. You are welcome. I've got tons of memories driving these trucks. If you look closely at the top of the tailgate, you will see two handles sticking up. These are used a grab handles when lowering and raising the tailgate, but also as a place to put your foot when climbing into the back. And driving on the left side of the road! My time in Oki was mostly spent Dispatching haha. Or driving a HMMWV, as I was with 3/3 on UDP out of Hawaii (Jul92-Jan93, Jan-Jul 94), so all we had in the Motor Pool (Camp Hansen) were HMMWVs. And you are 100% correct, these trucks will roll over a
  7. The whole hood tilts forward on these to service the engine. You can see the "T handle" hanging down from the top of the grill. You grab that with one hand, put a foot on the bumper and get it started opening, then grab the other handle on top of the hood to get it all the way open. The T handle is supposed to be stored horizontally, along the top edge of the grill on a small bracket with a lock pin. You can barely make out the lock pin hanging from the T handle on its safety wire.
  8. These really aren't that hard to drive. What was sometimes scary was sitting in the pass street as an Instructor. A friend of mine was instructing, and as the student was making a left turn at a 4 way intersection, in traffic, in the rain, laid the truck over on the pass side in the intersection. This was just before lunch. The instructor was picked up by our boss, driven back to Base, where he checked out another truck and was back on the road training after lunch. Haha, ya think? Luckily, we rarely needed low range. Six wheel drive, 1st gear, high range was usually enough. Dee
  9. Specifically, that's an M923 standard cargo variant 5 ton truck. More than likely US Army originally as it is equipped with CTIS (central tire inflation system) which the Marine Corps trucks never got. I was licensed on that truck in 1989. Most of us preferred the M813 (from the M809 series) which was a similar truck but equipped with a manual transmission. The US Army stopped widespread use of the 5 ton around 1999 and went to a different family of vehicles. The Marine Corps continued using them until around 2001-2002 when the new 7ton trucks were introduced (MK23). The M923s
  10. My MJ D44 came with 3.07 gears, wish it would have had the 3.55. I've already stripped the axle in preparation for 3.73s/& a Trutrac. I have the original set of 3.07 gears if you are interested.
  11. Jeep Comanches used two (possibly three) different knobs throughout their production: First pic was possibly used in early 1986, but usually seen on 84-85 XJs. 2nd pic used 86-90 3rd pic 91-92 some GM/Chevy hazard knobs will work, but are different. Early to mid 70s trucks used a simple screw and knob similar to the 87-92 Jeep type, but later trucks used a two piece assembly with a spring loaded collar, last pic. Trucks were always black, but various colored ones can be found in Cadillacs of the same era.
  12. Last week, plus a throwback to this past Spring.
  13. So the rear box is missing from the ambulance?
  14. Technically that's not the PCV valve, it is the fresh air intake for the crankcase ventilation system. That hose is hooked to the air cleaner where it draws clean filtered air into the engine. The Positive Crankcase Ventilation valve is the part stuck in the rear opening of the valve cover. It has a small metered orifice that is connected to a manifold vacuum source on the intake manifold. Engine vacuum draws crankcase gases out of the engine, and in turn fresh air is drawn in through the front hose. Excessive blowby could mean the metered orifice is plugged with c
  15. That's a great idea on the registry! And, I agree about the interiors. Unless you have a Country or other upscale trim, the interiors on the late model XJs are just blah.
