I'm sorry if this is posted somewhere, if it is, I couldn't find it. I also can't find a "steering knuckle bearing spacer" part # 25794670 to purchase. It's discontinued by Chevy/gm and I haven't been able to find an aftermarket alternative. (Had the car front end torn apart to replace all bushings/bearings, etc, and must have accidentally tossed one of the spacers. Gettin old!) Any ideas of where I could find one? Thanks for the help!

 

Was there one installed? That was a discontinued "fix" for splash guard. Not required, not really a spacer.
Probably not there to start with the other one was likely found somewhere.

 

I’m sure others have already not reinstalled that piece, me for instance, it is real thin didn’t make a difference.

 

Pick one up used?

 

IIRC, they were only on 2008, 2006-2007 had a full shield. The full shield caused over heating rotors and the smaller one didn't do anything.
They disappeared on my 2008 and not on my 2011.

 

My 2007 LS had these and my 2011 2LT has the full splash shield.
used at a pick a part is a good source.

 

Thanks for all the responses! I thought it was a "spacer" that was needed to locate the rotor in correct alignment with the caliper???? I'll try to mount it without the spacer and see how they line up.
