perfect. thank you. this truck has been a pain in the **** finding part for but i like the truck

no problem sir
glad i could help
just an FYI: when your replacing the seal on the center of the rod you will want to heat the seal up in boiling water to soften it so it won't break when stretching it over the center packing fixture. Then after installing it let it cool and shrink back up before inserting the rod into the tube, use grease on it so it will not get cut.
One thing i did not mention previously is to pay attention to the spherical bearings where the links connecting to the spindle axles and rod ends and make sure they are not worn out. If so they will need to be replaced also. If you have to replace any of them they are easy to remove, there is a small snap ring holding them in, one on the top and bottom. Most of the ones i had to replace i had to clean up the dirt out of the groove where that snap ring is just to see it.
The part number for that spherical bearing is 9144409600.
Part number for the snap ring is 9144401500.

is that a CAT part number or aftermarket? who sells them?

according to the serial number this is a GC20K
steer cylinder located in the steer axle?
seal kit for that cylinder is part number 9304400028
