How many grease fittings are there for the 2012 Chevy 2500HD D/A CC SWB ??? Seems each time I have the truck serviced I am supplied a different answer.
Look up Fabtech Chevy 2500 HD Tie 71002 3 X as large in diameter as Chevy and grease zerks. Original Chevy tie rods on 2500s have been known to break. I bought mine and it took about 2 hr to get them on and then I took it to Firestone and had a livetime alignment done for $150. Stopped some road walking also.
