What's up with the CJ-10?
The 10s were produced from 1984-1986, and most of the pickups were exported for fleet duty. The others are CJ-10As, or Air Force TUGs. Both were built on the J-series truck frame, and the CJ-10As had a transfer case with a lockout plate to hold it in 4-Lo for the torque required to drag airplanes around the tarmac.
Was there a CJ-9?
Nope.
What's a Mahindra?
The Mahindra "Jeep" is from the Indian manufacturer (started by two brothers) of the same name, and from 1947-1954 they used Willys CKDs or built these vehicles with Willys parts, eventually using their own component designs. Supposedly they built what was essentially a CJ-3B, but called it a CJ-4 and a 101-inch-wheelbase version dubbed CJ-4A.
Did Saab-Scania in Sweden make FCs?
Scania did receive CKDs in the early 1960s (it didn't merge with Saab until 1969). They assembled some but built others into custom configurations.
So was there really a CJ-4?
At least one Willys CJ-4 existed domestically and, like the CJ-1, it was a transitional model. It looked to have a CJ-3A tub and CJ-5 hood and unique fenders, all done to make room for the taller 134 F-head. Military versions were the CJ-4MA and CJ-4MP.
What was the 1990s' Jeep JJ?
The JJ project started with Chrysler in 1990-1991 and was to be an entry-level Jeep. It would be stripped of a two-speed transfer case (sound like any upcoming Jeep?), and it used a Chrysler transaxle mounted longitudinally to drive the front and rear axles instead of the right and left front half-shafts. The JJ never saw production because of unfavorable investment requirements--in other words, when Renault didn't want to do a joint venture with Chrysler, it was kaput.
Rare Jeeps are valuable, right?
Not always. We know someone who had an extremely rare model in near-mint condition, and he had the thing priced to steal (everywhere from local ads to eBay), but it sat for more than a year without a single phone call from collectors--or anyone.
Tech Editor Hazel is an idiot because he chopped up a one-off Jeep, correct?
His two-wheel-drive DJ has since been said to have been a prototype worth about $10,000-$15,000. But since he hacked it up, it's worth...well, it doesn't matter since it was the only one in existence anyway.
How did the Jeep get its name?
The long-standing stories are either GP (general purpose) or the 1930's cartoon character, "Eugene the Jeep."
Was a big-name off-road magazine's project vehicle responsible for inspiring Jeep to build the Wrangler Rubicon?
Many Jeep employees actually wheel Jeeps for fun (which results in R&D)! Someone who worked on the '70s CJs and who had paired a Dana 20 2:1 transfer case with 2.73 and 2.87 axle ratios was also the first person at Jeep to experiment with a 4:1 transfer case, selectable lockers (ARBs), and 4.10 axle ratios in his personal Jeep.

The AMC 20 has a larger ring gear than a Dana 44, but it's still a less desirable axle. Look, it's all dirty inside.
Jeep Parts and Tech:
Did some CJs come from the factory with an AMC 360?
Sorry, only the 304. Some dealers may have swapped in a 360 or 401, such as Randall AMC/Jeep in Mesa, Arizona. Was a barrel found in Australia containing Willys-Overland Jeep side steps?
Yes, although they were only the bottom part without the supports. Plus, they were later-production parts with a different diamond pattern on them.
Does the external oil filter on flatfenders need to be removed because it starves the front bearings?
The bolts that locate the rocker-arm pivot tube on the F-head are tapered. Rebuilds or servicing often resulted in straight bolts being used instead, so the rocker arm would move out of alignment, which would cut off the oil supply to the rockers; the first rod bearing to spin was always the number one because it was starved. Leave the oil filter alone.
