Spider Gear questions

Im going to look at a 79 bronco tmrw, and the guy says the 2 front spider gears are broke.

Im real green on axle tech, i do more long travel 2wd stuff.

So how hard are these to fix?
How expensive?

The axle must be a Dana 44 or Dana 60 if its on the front of a 79 Bronco.

Any info greatly appreciated.

Thanks!

you can get a new set of spiders for 100 or less, and they are very simple to replace. just need to pull out the axle shafts, pull the carrier, pop out the cross pin and install the new ones

is it dumb to run one up front, and none in the rear?

you can get a new lockright (lunchbox locker.. replaces just spider gears) for about 250 bucks, you really wouldnt be able to tell its there untill you put it in 4wd- it would steer fine in 2wd- they dont lock up till power is applied to that axle

Do you really need to pull the carrier? Can't you just rotate the carrier and push the pin out the front and the replace the gears? I'm just asking, I have never worked on a Ford axle.

Depends on the gear ratio mostly, the lower gears are thicker and will have to pull them to get the pin out. But if it is stock and most likely 3:54 no you do not have to pull the carrier.
