Differential Cross-Shaft Pin

[alrobjr]

I am trying to remove my axles to install a brake backing plate and I can't get the crosspin out far enough to remove the C-clips from the axle . The retainer bolt was broke and I got the threaded part and the other part was in the crosspin . Does the retainer bolt go into the carrier because cross-shaft has been turning with the spider gears . I got enough of the shaft out to remove part of the retainer bolt and hit it with a hammer but it won't bulge anymore .

Sounds like you have a piece of bolt sticking out of the pin yet, or possibly mushroomed the end of the pin. Try driving the pin the opposite way than you have been. You will likely have to replace the pin anyway so beat away with a large drift punch.

This is a very common problem. What should have been done first was trying to extricate the pinion shaft bolt with a magnet, needle nose pliers, or the specific kit that is available just for this.http://www.etoolcart.com/fabbri-differential-pinion-shaft-lock-bolt-extractor-kit.aspx At this point you may be able to use a large punch or another pinion shaft as a punch to push the stuck shaft through and out. However that assumes the broken bolt is short enough and will allow the shaft to exit without damaging the carrier. However it is very likely that forcing the pinion shaft out will damage or break the carrier so be prepared for that.

I used that extractor kit, works great! Removed the broken piece easily. That tool was a godsend.

I had the same problem with my cutless rear. The pin in mine was wore and that was not letting it move. I had to take the carrier out and cut the pin out with a torch. I wish you the best of luck

This happened to me when I installed my locker. I was able to take a small scribe and slowly turn the remainder of the bolt out. It seems like they always break in the last thread or so and they arent torqued down so they spin out pretty easily.

Very common for the shaft bolt to break. I've had to take many of them apart & the easiest way to get the remaining part of the bolt out is with a very fine tipped straight pick. When these bolts break, there is ALMOST always a very, very small part of the bolt thread left on the section that is broke and still in the diff. Out of the 50 or so of the broken ones that I have taken apart, you can usually stick a pick in the bolt hole and just back out the remaining section. Only twice have I gently and patiently had to cut the end of pin out and push it out the other side.

once my retainer bolt broke, the pin walked out and smacked my pinion ruining the carrier and pinion in my 8.5 so I sold the housing. In hind sight, shoulda kept it.
