Another front diff question

Hey all. I just bought my 04 Ranger 4x4 and am going to change ALL the fluids out in a few weeks. I have read many threads about how the front diff cover requires the removal of the cross member and other suspension components. I wanted to just use the suction technique but I noticed a very small drip at the base of the cover. I don't want to keep filling it and if I take it in water I would prefer a fully sealed diff. It is not leaking from the pinion seal and is for sure at the cover base.

Is there ANY way to squeeze your hands in there to loosen the bolts? If not, what if I could remove enough of the cover to drain the fluid and use a needle point extension to apply more sealant upon cover reconnection?

Has anyone successfully removed the front cover and replaced it and the fluid without too much trouble?

In order to get a good seal both surfaces must be clean (not oily). I don't know how that can be accomplished without dropping the entire assembly.

x2. The front diff really isn't known for leaking. Wash it off really good and wipe away everything and let your truck sit overnight. if its wet again in the morning, then its probably leaking.

And no, there is ZERO room to get that cover off and it wouldn't be wise to jut crack a bit of it open and squirt some RTV in there.

Thanks all. Like I mentioned, I just bought the truck so this was just poking my head around after driving it a few miles. I will brake clean the section and inspect it over night to see if it continues. I will need a new oil plug gasket/washer as the tech must have crushed the rubber o-ring on the one that is there. Other than that, no fluids leaking at all and I am happy with the truck.

I have had a 2006 tC for the past 5 years so it is good to get back to a real piece of machinery. The tC is my gas mileage car at 34the mpg, but I do all highway and have squeezed 25 out of the truck. New fuel filter and some TLC to all other areas should help too.

Damn just looked directly at the pinion seal and yup...that is the point of origin. It is VERY small, but will get more attention early next year when 4x4 engagement is more frequent.
