2.72, 3.55, 3.73, 4.10,4.56, 4.88, 5.13, 5.38, 5.89 Gear ratios available in Jeeps
8.8 Ford Axle out of the Explorer used as a reasonably priced swap for the D35. Only weaknesses are rosette welds and weak carrier.
297X The U-Joint size for a D-44 or a D-30 made after 1994. The 297 has been superseded by a better U-Joint called the 760
AMC20 Rear axle used in CJ's from 76-86
AX-5, AX-15, NV3550 5 speed tranny's used since 1991
BB Big block
BBD A cranky carb made by Carter
Caster Angle The angle of the top ball joint to the bottom. If you are looking straight down at the ball joints, the top one being more towards the front of the Jeep is negative caster..and it's bad.
CJ Civlian Jeep - Different models from 1946-1986
Dana 27 Jeep front axle, pre-cursor to the Dana 30
Dana 30(D-30) Front axle used in all Jeeps since..uh... a long time ago..before 1975 for sure. The new Rubicon is the first Jeep ever with a Dana 44 in the front.
Dana 35 or D-35 Rear axle used in YJ's and most TJ's - Weak axle tubes, thin ring gear, small carrier.
Dana 44(D-44) A family of axles characterized by the size of their ring gear. This axle was used in many applications in many vehicles, but Jeep used them in the rear late 60's/early 70's, the latter half of the '86 CJ-7's, and its optional in TJ's with a 4.0. the Rubicon has Dana 44's front and rear.
Dana 60(D-60) Never used in stock Jeeps, it's a 1 ton axle swapped in for brute strength.
Dana 300 (D-300) Transfer case used in CJ's from 80-86. Its a gear driven case. It is desireable for its strength and 2.62/1 low range
Death Wobble Horrible ocillation of the tires that will cause the Jeep to violently shake back and forth. Has many causes.
HEI High Energy Ignition. General Motors self contained ignition system that can be modified slightly to work on a Jeep 258.
IFS Independent Front Suspension
LOL Laugh Out Loud
MC Motorcraft usually used in conjunction with the Motorcraft 2100 carb
Mouse motor See SBC
MPI Multiport injection
Narrow track Jeeps up until the late '70s with narrower axles
NP___ NP is "New Process", a transfer case manufacturer. The 1987 YJ had some oddball NPXXX in it, but all other Jeeps since 1988 have the NP231 with a 2.72/1 low range. It's chain driven, but not a bad case. The exception is the Rubicon. It hs it's own special case (NP242)
Nutter A computer bypass developed by Mr. Nutter
Peugot(puke-go) Horrible 5 speed used in the late 80s.
Rat motor See BB
SAS Solid axle swap for those IFS rigs
SBC Small block Chevy V-8
SOA Spring over axle conversion - Take the leaf springs from a CJ or YJ to the top of the axels yielding 5.5" of lift.
SRS Shackle reverse...normally on front suspension. The shackel and spring eye positions are swapped.
SYE Slip yoke eliminator. The transfer case (NP 231) used from 88-present requires one with a lifted Jeep
T-18 The best 4 speed ever in a Jeep. They were from about 76-80 in CJ's and have a granny low unsynchronized 1st gear
TJ From 1997-Present - There was not 96 Jeep (Short Wheel Base)
TR upgrade Inexpensive (relatively) ignition upgrade designed by Team Rush
Waggie Wagoneer or Grand Wagoneer. Early SUV (I think you know what that means!) built from the early 70's until the early 90's. The narrow tracked ones are great donors for Dana 44 front axles for CJ's and YJ's. Also good sources of 360 and 401 cubic inch engines for swaps. Basically a good donor vehicle for all thing Jeep. In fact I even found that their front shock towers are the same as post '82 CJ's.
Widetrack Jeeps late 70s and later (can't remember exact year) with wider axles for stablity
YJ From 1987-1995 - Square headlight Jeeps
