My 2004 blazer 175000 mi needs new control arm bushings. I am having difficulty sourcing OEM GM control arms. Are dorman control arms going to also last 150k+ mi or are they not so good (10k to 50k mi lifetime) ?

Or is there another brand I should use?

 

I would replace the bushings in existing control arms with poly bushings and call it good. Are the cross shafts actually damaged?

 

I'm not a mechanic but nothing is visually obviously wrong with the shafts to my untrained eye. Who makes quality poly bushings?

It does seem that the OE control arm bushing parts are available:

The dealer mechanic I was speaking to I think had said that they used to replace the bushing only but sometimes it would get stuck or something so they only do the full control arm replacement now (??)

I'm kind of afraid of getting my vehicle serviced at a non-dealer after some bad experiences.
