It is not recommended to drive a 1990 Jeep Wrangler with no rear driveshaft, as this can cause damage to the vehicle's driveline and suspension components. The rear driveshaft is responsible for transferring power from the transmission to the rear wheels, and without it, the vehicle will not be able to move forward. Additionally, driving without a rear driveshaft can put strain on the transmission, axles, and suspension components, potentially causing them to break or fail.
If you must drive your 1990 Jeep Wrangler without a rear driveshaft, it is important to do so only for a short distance and at low speeds. Avoid putting any unnecessary strain on the vehicle, and be prepared for the possibility that the driveline or suspension components could be damaged. It is highly recommended that you have the rear driveshaft repaired or replaced as soon as possible.
