Front Driveshaft

Print

Jeep vehicles may come equipped with one of two different type front driveshafts. Type one has a conventional universal joint at the axle, but a double offset joint at the transfer case. Type two has a conventional universal joint at the axle and a double cardan joint at the transfer case.

Front driveshafts on 1984 vehicles use the type one universal joint only. Front driveshafts on 1985-98 vehicles use either type one or type two.
