## Questions & Answers

**Q: Will this unit work in a 95 ford bronco with 8.8 with abs tone ring.**
A: Yes, I installed it in my 92 f150 without issue, the tone ring is a press fit.

**Q: Does this fit a 2005 f150 8.8?**
A: Yes it will fit the Ford 8.8" in a 2005 F150

**Q: What kind of oil i use with this**
A: You would want to use the weight that is recommended by your vehicle's manufacturer which would be listed in your manual's specifications. But I would guess that 75W-90 is the standard weight gear oil for most applications. I use 75W-140 as I use my Tru-Trac for road racing and need more durability. I would suggest synthetic oil as it is more durable and requires fewer changes.

**Q: Will these fit a 2006 ford ranger fx4 4wd?**
A: This model is made to fit a Ford 8.8 inch axle. If you have that under your ranger, it will fit. Best bet is to go to the Eaton website and find the part number to fit your application, or look at your axle tag, door tag, or VIN number and see what axle you have.
