[Tigers] Axle removal process.

Sat Apr 18 20:46:07 MDT 2015

Cullen,
  Glad to here you got it apart.  Didn't know you were after the 
differential primarily. I also made a case spreader as per the picture. The 
threading spreader is a coil spring compressor held on point with a tube of 
electrical conduit.  Also, my axle puller. Eventually I added more weight 
(and wished I had 4 points of contact).  Is that really me? Fifteen years 
later I've turned into a gray haired old man!

*** update***

SUCCESS!  Thank you Tom Witt for the detailed description and Duke Samouce 
for graphics and offers to help. I would up approaching it like Tom 
described and it worked exactly as he said.

I sold the rear end (not the one in my car, this one came out of an old 
parts car) and I just wanted to keep the gears and diff. So I really am not 
concerned at this moment of putting it back together. Well, I cobbled 
together a nasty slide hammer out of pieces of structural steel pipe and 
welded it to an old steel wheel. 3 hard slides along a 3 foot pipe and those 
axles popped right out.  Built a quick case spreader out of angle iron and 
all thread and the diff came right out.

Thanks everyone!!
