swapping out a 9" yoke and pinion support in the car?

Can I swap the yoke and pinion support out of my 9" while the center piece is still in the car? Would it be easier to just take it out, and what extra parts besides the pinion support, pinion support bearing, solid crush sleeve, yoke and nut do I need? Thanks.

Yes, you can do it in the car - but the third member life expectancy might suffer!!

It's too easy to remove then to try to suffer rolling around under the car in that smelly gear oil you ARE going to spill:
- Jack it up and remove the wheels
- 4 driveshaft nuts (or bolts) to drop it
- 10 nuts around the circumference of the 'punkin'
- Dump the old gear lube
- 4 axle retainer nuts per side, then pull the axles out about 6 " though I would replace the housing seals and possibly the axle bearings.

You will also need a selection of pinion support shims (I got mine from Currie, but there are many other suppliers.

You might also need a new double dimensioned U-joint if the new yoke is a different size - this is a good time for a new U-joints anyhow. You might also have to shorten/lengthen the driveshaft, depending on the length of the new yoke
