So I start what I think will be a simple maintenance project and 'bam', right away something goes awry. I've got a rear axle seal leaking on my '71, so as I'm taking it apart, I remove the differential pinion shaft 'lockpin' and all that comes out is about 1 inch of the threaded part of the bolt - the rest remaining in the hole. I finally get the broken part out and a friend tells me "good luck finding a new one"! Are these items really hard to find?

Re: Differential Lockpin Availability
That should be available at any auto parts store. That system is still used on GM semi floating axles. Take the old lockpin with you to the store.

Re: Differential Lockpin Availability
They are in the help section at the autoparts store. I got one a few years back. Oh and congrats on getting the broken pin out. Those are a real pita to get out when they brake. I still havent got the one out of an axle I bought the pin for.

Re: Differential Lockpin Availability
That lock pin (GM calls it a screw) is still available at GM dealerships.

I've never thought of myself as being an impatient person when it comes to saving a buck, but after listening to my closest buddies prompting I went ahead and bit the bullet and ordered a set of new axles from Moser. They arrived this morning and they look real nice. Then I got on-line and read that Timken repair post.

Re: Differential Lockpin Availability
I had the same issue with the lock pin. When I got my truck it had a bad outer axle bearing, and had screwed up the housing along with the axle bearing surface. So I found a donor truck, bought it, and yanked the rear end out of it. This truck had been severely overloaded, as so many of these things have. It had completely crushed the crush sleeve, and driven the pinion back into the carrier, scarring it very badly. Upon removing the lock screw, I came up with about one inch of it. Since it was all trashed anyway, I took a 5lb sledge and a 1/2" extension (held with channel locks) to it. Took me a LOT of wailing and cussing before I finally sheared the remaining portion of the screw of, and the pin came out. Luckily, the axles and housing were still in good shape. So after mixing and matching parts from both rears, and a new bearing and seal kit, I had one good rear end and one good axle left over.
Glad to see yours went much better. But then again; if it's someone else's, it always does, LOL. Jay

From another post::: This broken bolt is so common. I've had three of them in the last 6mths at our shop. We use a specialty tool that gets this done in about 10 min. Got ours from either a Snap-on truck or Matco, can't remember, but did a search on google and found them online at www.fabbriassociates.com, www.etoolcart.com, www.skywaytools.com and even ebay. If time is money this kit is worth a months pay because we don't worry about damaging the carriers anymore! Hope this helps someone::: |

Re: Differential Lockpin Availability
Anyone have the gm part number for that bolt? The one in my 81' broke as well, however I lucked out and the rest of the bolt was not seized in so it ran out easy.
