How to remove broken front axle disconnect housing from the oil pan

Hey there. After doing multiple searches and coming up empty I decided to post how I removed the broken half of the front axle disconnect from the oil pan on my 2002 TB. I was very concerned about cracking the oil pan and having to replace it. What I ended up doing was drilling two 17/64" holes(no longer than 1" deep) on either side of the housing and then tapped it with a 5/16 18 pitch tap. Then I threaded two 5/16 bolts about 3" long into the housing and used my harmonic balancer puller to pull on the axle shaft and remove the broken piece out of the oil pan. My first attempt was with a steering wheel puller but it stripped the threads on the puller. This thing was really stuck! I also tried using a slide hammer with the bolts but had zero success. I also sprayed around the broken piece with WD40. I'm not real sure this helped but I thought it couldn't hurt. I really hope this helps someone else out. Cheers. McLuvin
