Front Differential Mount Bushings

[Ron Kaylor]

On my 1999 Chevy Silverado 2500 I am in the process of removing the old rusted through frame and installing a refurbished frame.  I noticed the replacement frame is missing a bushing (right side frame) where the right side of the front differential mount bracket ( GM part number 23229694) attaches.  GM told me this bushing is not listed, but was a part of the frame.  Does anyone know a form/fit/function bushing that may work?

That's the same thing I got from the gm dealer here when I added 4wd to my truck.  Don't know a cross-match, but they seemed slightly tapered.

 

I got the two bushings from my parts truck, by using a drill with about a 1/4" bit, and drilling right in the edge between the bushing & the frame, then once through to the other side, letting the drill bit walk around the bushing.  This released the bushing from the frame, with no significant damage.  Then hammered it into the frame a bit with a tube on the rubber (from the inside of the frame, as the hole on the  outside of the frame is smaller).

 

So far, it's been in my truck for 3 years or so, and working fine.

 

So, I would suggest getting it from a junkyard, with a drill and a hammer (to get it out after drilling).

Excellent advice!  I did as you suggested and the bushing was removed with little to no damage and installed it in the refurbished frame. 

 

Thanks again!

Still looking for a replacement part if any one know one that will work.

Like I wrote, your best bet is to get them from a junkyard...  They are slightly tapered, and GM never offered them as a separate part.
