EDITED 5/16/2009
I wrote previously that I would publish an update on this topic, so here it is!
To refresh anyone's memory: Spicer Stuff
All items listed here have a GM "long number" and can be ordered by any GM dealer. All numbers starting with "45---" are ACDelco.
If there is anything I missed, or if you are looking for info on another vehicle, just let me know. I can also provide equivalent P/N's for Moog springs from the ACD listings.
Some Moog and other source equivalent kits are packaged differently than the ACDelco parts, with multiple parts in a P/N package--especially bushings--where ACDelco is NORMALLY packaged as a single item, except where indicated.
NOTE: Prices should be checked locally or at GM Parts Direct online. You can also submit a pricing request here: RMS Auto Parts to find out what these parts may actually cost at present. Remember that GM parts are subject to frequent and inexplicable price adjustments--usually higher, rarely lower.
The bottom line is that you can purchase quality parts from GM, rather than have to wonder whether that idler arm you just bought at CarQuest, Auto Zone, Pep Boys, or the local parts store is REALLY the same one that comes in the blue & yellow box with the racing organization logo on it.
Finally, realize that these are NOT Moog parts. They were Dana/Spicer aftermarket (now Raybestos, part of the Affinia Group, a spin-off from Dana several years ago), NOT to be confused with OE parts used in production.
These ball joints and other articulating parts are "low friction" design. They have other features which I consider superior in most respects to other frequently used major brands. In most cases, since they are the most familiar to this group, I have provided the Moog number for the EQUIVALENT to what is in the ACDelco package.
Here's the "complete" list (does NOT cover every part or application) :
FRONT & REAR SUSPENSION & STEERING PARTS
NOTE: listing is a mix of GM and ACDelco parts--some production parts not supplied by ACDelco are also listed. The NAPA parts listed are the same as the GM/ACDelco parts where all PN's are listed. All are manufactured by Raybestos as noted above.
FRONT SUSPENSION
