Found out the front diff is leaking a lot of oil from the seam where the two halves of the diff bolt together.
I have a 4" rancho lift kit on my 2003 H2. Anyone know how hard is it to remove and reseal the front diff ?
thanks

 

Quick and easy. Buy a seal from an autoparts store and some gear oil. Drain the diff after removing your front skid protection. Remove top nut, remove bottom nut and let the fluid drain. Remove all bolts from the diff and take off the cover. Use good something like brake clean and a rag to thoroughly clean the old gasket off of the cover and the diff itself. attach the seal back to the diff with a THIN layer of RTV, apply to outside of gasket and put the cover back on. Snug everything down, I like to use a star pattern like you are doing a wheel. Reinsert bottom plug, add approx 2 quarts of gear oil of the proper weight. Just enough fluid that some start to come out of the top hole. Tighten up top nut, reattach skid protection.

 

The dif uses 75W-90 synthetic like Castrol Syntax or Royal Purple

 

thanks guys.
I noticed some of the bolts on the diff were loose. some of the bolts were so loose I could turn them with my fingers. I tightened the bolts to 37ftlb of torque and not a drop of oil yet .I still need to take it for a longer drive and check again.

 

dont forget to fill up diff back to proper level
