This is our trail runner project we’ve been having a little bit of fun with, but why is it on the table today? Well, from pretty much the moment i took it out of the box, it has had a problem. What is that problem? Let me show you and here’s. The problem is the shocks since day. One this shock right here has leaked, as you can tell from the shock here itself is covered in grime and dirt that’s been attracted to it by the oil i don’t know for sure. If this is a cap problem or a body problem, but given the fact that this is a metal body shock, i want to assume that it’s the cap. So therefore, from day one i’ve been running this truck with no shock oil in the rears, the rear. I mean look how bouncy it is not good for performance. So what we’re going to do is i’m going to take this shock off, get it cleaned up pop this stock cap off and fill this up with some oil and try the new cap out, and this is what we’re going to replace those leaking shock caps with These are the strc aluminum shock caps and gun metal, so hopefully this will fix our leaking shock problem so, like i said, these will look better and hopefully will perform better and give a little bit extra strength up top as cheap. As these kind of things are, i don’t know why manufacturers still include plastic shock, gaps and bodies, but anyway, let’s get these here’s the part number for them.
Stc 420. This one has a gm on the back for gunmetal and they come in other colors too. I know for sure they come in silver and black and probably other colors anyway. Strc is known for making good parts for the axial vehicles, so let’s see how these do on the element. So let’s go ahead and get the shock off. It’S really easy to do. It’S got one bolt up top right here and you have another one right here: the good thing about this bolt right here. You don’t have to take tire off to remove it. You can get to the bolt by going through the tire, so i get to slime. See right there, you can see the bolt through that hole in the tire in the rim, so you go through the rim to get that lower mount off so i’m going to do that and then we’ll go through changing the caps start by taking off the top Screw right here and now for the bottom bolt, so let’s go through the tire here there we go now. If that shock is out i’m going to take this shock and clean it up. First thing i’m going to do is take this shock apart by taking the spring and the retainers off of it. You don’t have to to remove these tops the caps, but i prefer to because i need to clean this shock off and it’s easier to clean it. Without the spring, in the way, so let’s go ahead and take that apart, real easy in case this is your first time just pull up on the spring here.
This little cap here will slide down and see. It has a little split in it so that it slides right off the shock cap or a shock shaft like so, and just bring the slides off the end. You can see that dirt and grime there. What i like to do now is take a paper towel and wipe that grime off before i thread this down off the shock by using a cheap paper towel just going to wipe down the shock body just to get the dirt and grime off. And then we just thread off the collar. Now the next step is i’m going to take some alcohol spray it on paper, towel wipe down the shock clean, all the dirt and grime off of it, because there’s a lot of grime down here on the end and that way there won’t be no dirt here To contaminate the new shock oil now i’m, going to clean both the spring retainers and then, of course, the spring. This is the shock that kept leaking on me. It kept leaking right here on the cap. I think it’s just a defective cap from ae, because i you take it off, you check it, make sure it’s clean the threads look. Okay, but you put it in snug it down and it’d still leak fluid around it. So, like i said, i think, it’s just a bad cap, we’ll replace it with one of the ones i showed you beginning of the video from strc.
Removing the cap. Don’T have to worry about spilling any oil, but just in case i have the bottom out of a soda bottle here to catch any old oil. So you can see she is bone dry so now to fill it up for full oil i’m using associated 40 weight oil, stopping not filling it up all the way. Yet i want to work the piston to make sure i get any air off underneath of it, but make sure you push the piston up. You do not uncover it all the oil, otherwise you’ll be sucking more hair right back down into it. Just do this. A few times, okay, now i’m going to add some more oil there. It is get it up towards just barely come over top. It makes like a little hump a little dome. You don’t want spilling out everywhere, but i want to make that little dome there. We go, and now we put on the new cap – i didn’t really mention this before, but always make sure your o ring is in good shape whenever you’re changing your caps or changing your oil. This one is in good shape, so let’s go ahead and get this screwed on let’s go nice and slow, so you don’t, displace a bunch of oil and once it’s tight let’s give it a little bit of turn. You want it. Snug, not tight the metal ones. It’S not such a big deal, but on the plastic ones will deform the caps uh, sometimes with the metal ones.
It can deform the o ring so go ahead and tighten it down, make sure she’s, nice and tight or snug. I guess you should say, and then we’re going to take a paper towel, wipe off the excess and then cycle the piston and check for leak i’m, not seeing any leaks yet that’s, a good sign just keep going all the way around there we go. My shock is completely full said once again not seeing no leaks, we’re working the piston in and out we’re turning it over. So it looks like this is going to solve our leaky cap problem. Now he’s got to put the right height adjuster on put the spring and then the bottom spring retainer, so let’s do that now. The purpose of this little collar right here that i’m putting on is to adjust your springs. Your ride height, a lot of people, thinks it’s to make the springs firmer, but moving it down, but that’s not really what it’s, for, though your springs will get a bit firmer. That’S not the point adjust the firmness of your shocks with the oil or the softener supplements case may be. This is to adjust your ride height. This determines how high or low on the shock body of the spring sits and also affect how much droop it has down. If you want to always at full extension nervous at rest or like i like mine to rest about the middle that we have up and down travel but anyway, so we’ll put it back on.
I was running these all the way at the top, so i’ll work. It all the way back up there and now the spring goes on and then finally the retainer goes on the bottom. There we go, this shock is finished now, just got to put it back on the truck. Installing them is just the reverse of taking them off there we go. The shock is now reinstalled with the new shock cap. Hopefully, there’ll be no more leaking i’m gon na go ahead and redo the other three shocks the same way remove them drain the old oil. If there’s old oil in it top them off change, the caps put them back on i’m gon na go ahead, and do that then i’ll be back to give you my final thoughts, and now we have the strc shock caps on all four corners. All four shocks are refilled with oil. The front ones here have 35 weight oil in them and the rears have 40 weight oil in it. It’S all team associated silicone oil, pure silicone wheel, and, as you can see, it’s a good looking shop cap. It matches the shock itself, the parts already on it, the collar and the body very good. If i had to make a complaint about this shock, cap it’d be that the gunmetal isn’t, quite as gray as a lot of gunmetal out there, but it still looks good on the truck and, like i said it, seals good.
None of these shocks are leaking i’ve. Cycled to many many times so now, we’ve taken care of that leak. Speaking of cycling, if you remember in the beginning of the video i pushed kind of violently on the back of the truck and it shaked and bounced and everything else, here’s the advantage of putting on your shocks notice, it’s, not really bouncing around. When i push on it, it’s real, slow and controlled that’s, why you need oil in your shocks, so there you have it. This is my review of the strc shock caps. They are a great addition to any rig, especially this one, because now the oil is staying inside the shop where it belongs so it’s not making a mess everywhere and performance stays consistent. So these are definitely well worth the money so what’s. Next, for this little truck, i think we’re gon na add a winch next, just because i think it needs a winch, it has a spot in the bumper for it, so let’s go ahead and add one so make sure you subscribe. So you don’t miss that video or any other updates. We do this truck and there will be plenty more coming forward. I guarantee you that i’d, like to add a set of weights in the wheels at some point i’d like to add an interior so like so we have a list of stuff.
