If you have LS does that mean its in the front too ?[/QUOTE]
Check Dana 44 ID tag for ratio and if STD or LS Limited Slip or what Dana describes as "Trac Lok"
Steve has a list of Dana 44 Bills of Material (Dana Part Numbers):
610335-2 Trac Lok 3.54 88.5 - 92 1/2-ton
Front Axle Tag TSB 92-05-14 for 85-92 Bronco, F Series, Ranger & 91-92 Explorer
The 1991 and
prior model front drive axles had identification information in the following three (3) places:
1. It was on a metal tag attached to a carrier cover mounting bolt.
2. It was stamped into the left side axle arm (tube) front face inboard of the U-Joint.
3. It was on a paper tape tag wrapped around the axle arm (tube).
The 1992 model year axles use a glue-on label that replaces all three of the prior identification markings. The new label is on the rear face of the right hand arm (tube).
ACTION: Since this glue-on label is the only identification, be sure that the information on the label is recorded in a retrievable place before any service actions are taken which will damage/destroy or remove the label.
Also check Door Jamb Label (Certification Label, also referred to as the Patent Plate, Data Plate & the Warranty Plate)
3rd digit: Any character (usually 2 or B) indicates a limited slip front axle (4WD)

He has a H9 rear 8.8 (as Built) and there is no other identifier for front so w assume it is Dana 44 Std
