Ok my son nailed a curb and broke his rotor caliper and rear end is damaged. We have a 2002 jeep grand Cherokee Larado with a dana 35 3.73 gear. We found a fully intact 2000 jeep grand cherokee rear end dana 44 with 3.73 gears. Ive read they are fully interhchangable on some sites ad other say you just have to have the 44 drive shaft and they interchange and another said the Yoke and shaft will have to be a custom weld and another says they are different bolt patterns in mounting. Can anyone give me some guidance on this.
