gear set questions

So after hearing some nasty clunks coming from the rear, I pulled to cover to take a look. I have never worked on gear before so this is all new to me. Once the cover was off I knew i had problems once I saw the metal pieces. Most of the teeth were pretty rounded off or broken. The ring and pinion looked fine and seemed to show no wear. Now what is the exact name of the small inner gears. Differential gear set? Spider gears? And how hard would it be to replace? I'm low on funds so I am trying to be on the cheaper side. Would I be better of with a junkyard part (350$) or just rebuild mine. Or should I take it to a shop and have them do it ( what is an average price) Thanks for any help

Can't give alot here but, yes they are spider gears. If your up to the task, as long as your R&P is good, replacing the spiders isnt that difficult.

the top and bottom gears are the spider gears, the left and right gears that go over the splined axle shaft are your side gears.

a junkyard or salvage jeep supply will be the best bet for replacements.

very often, all 4 gears are called the spider gears, but i don't THINK that's technically correct. or maybe that's just the terminology around here... kinda like soa vs. pop i guess? i dunno...

not all dana 35 spider gears are the same either. the non c clip and the c clip gears are different... not sure where else the breaks were but i'm thinking it was 87-90, 91-93, 93-96 the 93's overlapping somewhere maybe? i forget.

be sure to keep track of the thrust washers when you remove the spider's and side gears.....
