How complicated is it to change the Tie Rod endings? Can a person with normal set of tools do it? the dealership wants to charge $130 for the labor alone, they don't look too complicated so i figured i'd ask before investing in the dealership.
Also, how hard is it to replace the Idler Arm? I also need that replaced, and I am quoted about $200 for that from the dealership.

Well they are not the easiest thing to change but they will require some effort on your side and there is a good chance that after you put the new stuff on the alignment will be out of shot so you will have to do that again... But it will most certainly take a few hours of your time. i had an issue where the ball joint wouldnt come out and I had to pound on it but o i was able to get them out. The problem is the parts none of the local stores have em so you will have to go to the dealer and you know how they charge... parts alone should be something like 150$... if you get lucky.

haha, you're right.
I am ordering the parts off Ebay, for both sides it's costing about $140 US, which is hell a lot cheaper than dealership that wants to charge $600 for the parts alone.
quick question, since you have done the replacement, were the tie-rods for year 2000+ revised at all or redesigned? reason why I ask is that I know a person that is selling the tie-rods that will fit 97-2001 (German made). And the part looks similar to the one from GM. However, looking at the pictures of tie-rods of 97-99 from GM's dealer, the part looks very different from 2000+.
I have a 2000 Catera.

Another place to check:
www.cadillac-parts-dealer.com/parts.htm

Inner Tie rods are listed to fit 97-01 but outer tie rods listed for 00-01...

what sub-category would tie rods fall under? i cannot locate the part under brake/wheel-hub.
