Hey Folks,
I took on the task of replacing my rear spring perch ball's part # A-4024but found nothing on the web as to how to go about it for a 31 Tudor. I couldn't find anything on Youtube Video's nor could I find anything in print and pictures for the tapered Perch balls for the 30-31 A's. I know the 28-29's were to be cut and drilled then weld the balls in. I have seen info on that, but as I said, nothing for the 30-31's, so I decided to make a quick tutorial on how I did it. It took about 40 minutes to do both sides. Hope this helps others in the future, IT'S PRETTY DARN EASY!
Tools used,
4.5" - Wire wheel
4.5" - 24 grit Grinding Disc
4.5" - 120 grit Flapper Wheel
3 - Jack stands (rear end removed from vehicle)
¼" – Drift Punch
Porta-Power
30 oz. or so Ball Peen Hammer
Torch (heat)
Scotch-Brite or Sandpaper
1). Place the rear end on 3 jack Stands.

2). Use a wire wheel to clean off any dirt/grease around the perch and ball that may be present.

3). With the 4.5" - 24 grit grinder wheel, grind off the peened over end on the backside of the ball and knock out the ball. Then clean up with 120 grit flapper wheel.
4). Place the Porta-Power on the perch and the top Differential Banjo Bolt, and once both ends touch, add ½ pump of the handle to snug up enough to counter the force of the hammer but not stress the perch much.

5). With the 1/4" drift punch, 3-4 hits should pop out the old tapered ball.
6). Clean up the inside of the hole and the new balls with Scotch-Brite or sandpaper.

7). Tap the new balls into place.
8). Now place the Porta-Power on the flat face of the perch balls and again on the top center banjo bolt. Again only tight enough to withstand the hammer.

9). Apply heat to the back of the ball until cherry red and peen over the end.

Clean up with the wire wheel and give it a squirt with your favorite Chassis paint and then go have an Ice Cold Beer and admire your work, you're DONE!
