What rear end does a 1999 jeep wrangler come with is it Dana 35 or 44?

The 1999 Jeep Wrangler came standard with a Dana 35 rear end. However, some models were equipped with a Dana 44 rear end as an optional upgrade. To determine which rear end your Wrangler has, you can look for a tag on the differential cover that will specify the model number. Additionally, the Dana 44 rear end is typically wider and has larger axle tubes than the Dana 35 rear end.
