12 bolt confusion
After breaking a drive shaft/u joint/yoke last week at the track I decided to open up the rear end and make decisions on what to upgrade. Inside I found a part number ydggm12p-3-30 on the carrier which is a Yukon gear and axle 500 dollar posi unit
![]() The confusing part is that part number is for a car 12 bolt not a truck 12 bolt? So do I need a car ring and pinion or a truck ring and pinion? I know I need truck axles because of the larger bearing size but will the work with the car posi?? Honestly much like transmission I don't know anything about rear ends so any help would be great! Thanks Carter |
