Check the fluid and make sure that you arent completely empty, if you get a chance just drop the cover and change and reseal the diff. pulling a trailer like that i would definately check it immediately

Like I always say, as long as its leaking theres fluid in it. Is the leak high up on the diff cover, is it the pinion seal? Check the level and add if you have to.

thats true if there is no leaking its prolly cuz thers no fluid. in this case a leak would at least let you know that there is fluid there

Thanks I ended up adding fluid every 100 miles or so due to not wanting to break the truck. The first time I added fluid it took almost a quart then did not need much at all the other stops. I am going to work on it tomorrow and just clean reseal and add all new fluid got my trusty tube of black silicone gasket and 75-140 gear oil.

Can anyone point me someplace to figure out what rear diff I have? There is only one tag, which does not seem correct. The tag has the gearing 4.10 then v2034 ua on top line & bottom line reads 606781-5 ls. I have done several searches and called the local Ford dealership shop who was unable to give any info saying "that tag makes no sence" but this is the same shop that has given me wrong parts.

Any info would really help thanks
