I've not been able to find a part number for that roller in the door jam that the spring pushes against. I even called the dealer and gave the Vin number but the part number I got was for something else. Does anyone have a list of part numbers? This is for a 2002 blazer, BTW.

 

A quick google search for S10 Door Hinge Detent Roller returned the following tutorial:

Car Door Won't Stay Open - How To Replace Hinge Detent Mechanism

The above link references GM part numbers 14030534 & 20058035. Dorman 38433 looks nearly identical, but only lists the fullsize trucks in their applications chart. and says it's applicable.

 

​​​​​​Cool. Thanks!

 

The irritating part is that the originals have to be ground down on the head or sheared off with a chisel to remove them since they're sort of "stamped" in. The knew replacement ones are easy to install though; drop in and pop on a C-clip.

Do yourself a favor and grab one of the detent spring removal tools, save yourself a TON of headaches...

 

Mr. Green, I hope you will take the time to write up the removal and replacement of this roller. I am sure many here will appreciate it. Thanks, Jim
