universal joint??
 

Why does my 05 silverado LS take universal joints that are for the SS model? I checked with three different parts stores and the ones in the book for the LS were too small so I brought in the old ones and they matched up with the SS. Anybody know why this is??

What are the specs on your truck? 2wd/4wd? Maybe the truck was ordered with a different gear ratio typically reserved for the SS? If you have the window sticker, that would be very helpful.

Maybe someone else will have some input?

Hi yes I do have the window sticker it is an 05 silverado LS 1500 4wd ext cab
