How to Lube Rusted Parts

Video Transcript

Hi, my name is Nate McCullough, on behalf of Expert Village. In these clips we are going to talk about the proper way to inspect, remove, replace and maintenance your vehicles shock absorbers. In this clip we are going to talk about some of the surface prep you can do if your fasteners happen to be seized. On most vehicles, I'm going to say approximately ninety percent, the fasteners for your shock absorbers are exposed to the wheel well. Depending upon where you live in the country you are going to be exposed to lots of salt, snow and ice. As you can see everything under here is rusty. From the coil springs to my brake caliper, and of coarse the fastener for my shock absorber. The one thing I'm going to recommend to the do it yourselfer to use is penetrating oil. When you do this repair you have time on your side. Shocks don't go bad all at once. So what your going to want to do, is a few days before you attempt to service your shock absorbers, is give them a good squirt. Just like so, That?s the lower fastener, and up here we have the upper fastener, we are going to give that a good squirt as well. Give it a few days to sit and let the penetrating oil do it's job. If that doesn't work, if you unable to remove the fasteners when they have been soaked in oil for a few days, the only other way to get them off is by heating the nuts up with a cutting torch. I'm not going to recommend that to you as a do it yourselfer . This shock absorber is a sealed unit and carries oil under high pressure, if you over heat this cylinder it will explode. As i said I'm not going to recommend that, if the penetrating oil does not work for you, do not attempt to heat them up yourself. Take it to your local mechanic and have them do the shock job for you.
