Yes, the guide pins need to checked for wear and then re-lubed with silicone brake lube and reinstalled.
It is reasonably high precision. If the guide pin bores are not machined perpendicular to the bolt boss faces where the saddle bolts up to the knuckle, then the pads don't sit square to the rotor face and the guide pins bind and lock up when the brakes are applied. There should also not be enough slop in the pins or holes that the caliper can rattle.
I removed the pins and greased them but they are still loose. I have attached a video file.It is reasonably high precision.

We take a lot of shit for granted that has a lot more to it than meets the eye.
Can you give me a part number or do I need to order from your website? I can't find any guide pins that match what I am using.
Thank you so much for the fast reply. I have one question, in the picture the two guide pins are different. I have attached a picture of my guide pin which is the same of the top and bottom.
The two that are different are OEM and a better design since the rubber bushing helps stop the rattling.
The guide pin kit just arrived today, I installed them and the new pins are still loose when installed, especially the bottom pin. It appears the bottom hole is more worn than the top. Do I need to order the part that the pins fit into? I apologize but I do not know the name of the this part. Thanks in advance.
Caliper saddle or caliper bracket. https://www.autozone.com/brakes-and...VIRvnCh3VpQfJEAYYAiABEgJ_v_D_BwE&gclsrc=aw.ds
Thank you mrblane, the caliper bracket fixed the problem.
