Default 3.80 swap progress (first drive! Weeee)

SO far so good.

I got the 3rd member out without effort, damage, or injury

Dave was right it was just like he said...but rather than try to catch that greasy hunk of iron i just set two small lawn tractor tiers under a piece of wet plywood and levered the 3rd member out and let it fall the 3 inches onto the shock adsorbed plywood.

the whole deal took about 30 minutes of actual work

Found a near by company that would do the gear swap for about 250.00 so that sounded reasonable to me.

These are the gears I got http://store.summitracing.com/partdetail.asp?autofilter=1∂=SUM%2D740802&N= 700+115&autoview=sku

I hope they fit...I guess ill know by next week

Anything else I should do or know while its apart?

Why in the heck did you go with the 3.80's for![8D] Just kidding. You are saving yourself several hundred dollars by doing the R&R yourself. Better do like Scott said and just replace the seals while you are in there. You may have changed them the last time you were in there. If so they should still be good. Keep us posted. We want video's of nasty burnouts.

I'd replace seals and bearings while you've got everything apart. Granted, it's not like a c-clip axle where you have to pop the cover off to remove an axle, but I still wouldn't really want to pull everything apart again for a shot bearing. You'll have to get a shop to press the bearings on and off, but if you plan on using that axle for a while, I think it's worth the peace of mind.

I usuallys say, if it aint broke dont fix it.Rear axle bearings generally dont go bad unless it had a leak and the gear oil ran out. I have pulled 9 inchers that had well over 200k miles on them and they were still good.

The real point here is to inspect everything. If anything is questionable or in poor shape, replace it.

If i do anything its just going to be seals.

yeah, you must just be out banging gears or something, huh? You were meaning to get back with us but you can't because you are out having fun.
