Rear Differential Pinion Seal on 5.7L


Summarizing info. on what information I gathered is the nut is 32 mm and the rear pinion seal stock part number is MOPAR 52070339AC for roughly $30 CAD.

W/8.25" Ring Gear.

Or the SKF 17350 for $11, the TIMKEN 710480 for $13, and the NATIONAL 710480 for $16. Minus taxes and shipping.

And some folks use gray RT silicone or black...but these seals already come with a rubber ring that should seal as it's getting pressed in?

Torque the front and rear pinion flanges to 80 ft lbs.

Video not for a Commander but good tip on trying to move the flange up and down to see if there's movement and a bearing needing replacing?

Kind Regards,
