Question: I am looking to buy a 77 CJ-7 and not sure if it is the wide or narrow trak. What is the dimensions of both, I assume you measure from hub to hub. It also comes full time 4 wheel drive with a vacum type locker assembly??? How strong of a 4 wheel drive will this provide (standard off roading with 32″ tires, all 4 tires turning when articulated)
Answer: The 77 model and all models prior to 1982 had the narrow trak axle so it’s not likely the Jeep has wide traks. A Quadratrac model was never offered in a Jeep equipped with factory wide-trak axles since the rear differential is off-set to deal with the Quadratrac. The swap options in this model Jeep are almost zero if the Quadratrac is going to be retianed. The full-time system that came in the late 70’s CJ-7’s is actually a pretty strong system and should hold up to your kind of use just fine. We have seen many of these CJ’s running trails for years.
