I need to change my rear pinion seal on 2007 Durango with a 5.7. I was told you can find the gear size by counting the bolts on the rear axle pan diff cover, if so how many bolts equals what size gear?? I need to know so I can get the right seal. thanks for the help

 

Or, you could go here, click on 'equipment listing', enter your vin, and it will tell you what your truck has in/under it.
