I have a 1996 dodge ram van B2500. It is a rear wheel drive van. I noticed the front shock absorber under the driver side was leaking. I intend to replace it with a new one. The shock absorber is between the upper and lower control arm and is inside the coil spring. I consult the service manual. It just says 1)remove nut and bushing from the shock absorber upper stud. 2)Raise vehicle, remove the lower attaching bolts and remove shock absorber. When I try doing those steps, I find that I cannot even do step number one because the nut and the shock upper stud were so rusted that they stick together. When I use a socket and wrench to turn the nut, both the nut, the bushing, as well as the upper stud turn together. I spring some W40 but it does not seem to help that much. I was not even able to complete step number one as described in the manual.
My question then is what can I do now to loosen the nut so that I can remove the old shock absorber.
