Differential removal

Post by Dutch »

So I have been rebuilding my front axel, completely tore the knuckles apart new seals and goodies to go back in. My question is how heavy and hard is it to remove the differential and carrier assembly? Once I remove the bolt that hold it in will the ring and pinion and shins and stuff fall out? I'm a one man show and not sure the best way to try to remove it by myself. The axel is still in the truck

The pumpkin is around 120# so you don't want to pull in unless you have a jack ready! If you have the axles out it's no big deal to pull the 3rd member, just be careful.

Andy is right; use a tranny or floor jack for support if you have one.

Dutch,

Yep as others have said easy, just darn heavy laying under a truck. I've found with a normal Jack or even my trans adapter the differential is still hard to keep from rolling off or aligned. I've had mine out way too many times, and finally built a dedicated jig to use on my floor jack.

its a drop out unit which means no parts fall out when you take the diff out. the whole assembly comes out. always use NOS diff gasket if yours is not re usable. the modern replacements are NOT the correct thickness. Thickness is important because it keeps the side gears perfectly aligned to accept the axle shafts. All the suppliers usually have the NOS gasket kits.
