Meritor King Pin Installation Instructions
Some shops do have the spindles sent out to machine shops to have the bushings installed. I can't speak for those shops. Are you missing something? Did you ask each shop in detail what work is actually being done for that price, or what parts are being installed? Maybe FTLNR is totally ripping you off, maybe TA is installing complete junk. Simply asking, 'how much' isn't sufficient.
Meritor King Pins Cross Reference
Go back to FRTLNR and tell them you where quoted half that price and ask they why they are double. Go ask a third shop.
