CJ has narrow leaf springs, round headlights and had a very long lifespan. 4cyl, 6cyl and V8's were offered from the factory. Models ranged from very short wheelbase to the CJ8 which had 110inch wheelbase.
YJ has wide leaf springs, square headlights and was the direct decendant of the CJ. Many of the CJ7 parts are interchangable with the earlier YJ's. YJ's are a more comfortable ride than the CJ
TJ has coil springs, round headlights and is the decendant of the YJ. Very few parts are interchangable between the YJ and TJ (engine pieces and some parts of the axles). The TJ is a very cushy ride compared to the YJ and it has things like airbags and CD-players that YJ's never had.
