It will be easier if driven up on ramps to give you more clearance.
You may have difficulty removing the pinion nut. Other than that it's a straight forward deal.

But mine has a piece of plywood bolted in the bed and when it is removed you can stand inside the bed with both feet on the driveway and work on everything. I have pulled the chunk from the rear that way. It will stay that way because I'm way to old to crawl around under there until something breaks under the front half. | | | | | Joined: Feb 2011 Posts: 1,362 'Bolter | | 'Bolter Joined: Feb 2011 Posts: 1,362 | If you want to do it correctly its a big deal. Need a new crush sleave and proper preload.
Kicking self for selling off my Taskforce trucks.
Still looking for an LCF or conventional big bolt in decent shape.

I do not have it jacked up. I can easily work under this one on my driveway.  | | | | | Joined: Feb 2006 Posts: 1,867 Shop Shark | | Shop Shark Joined: Feb 2006 Posts: 1,867 | If you want to do it correctly its a big deal.

And setting pinion bearing preload. Gear contact pattern, and back lash, and carrier bearing preload. Its probably best to take it to some professional differential outfit and let them eat it if it is setup improperly. Done wrong they don't last long and sound horrible, and really chew things up nicely.
