Installing Differential Guards From Terrafirma On Discovery Series II
Outfitting a Discovery Series II for Off-Road, Part Five
Watch Doug, our Land Rover Master Technician, in Part Five of our video how-to series, as he installs front (
TF838) and rear ( TF839) differential guards on our project D2. Doug will discuss the importance of adding protection to your front and rear differentials if you intend on using your D2 for off-road. When off-roading, these guards will add an extra layer of protection to your vehicle's underside. Questions about this video? Call us at 1-800-533-2210 or contact us via live chat. Outfitting a Land Rover Discovery Series II for Off-RoadHello. I'm Eric, a sales rep here at Atlantic British. Today we're going to talk about building up a Discovery 2 into an off road vehicle. They've gotten really affordable now. You can pick up a D2 for $3,500 to $5,000, put 3, 4, 5 thousand dollars into it and have a very good off road vehicle. This one we picked up a couple years ago. We've been driving it around, using it as a test mule. So now we're going to build it up into an off road truck. With Doug's help, we're going to put suspension, front and rear bumpers and then slowly build it up into a lifestyle truck. We'll have videos that will show Doug doing each process, and we'll post those as time goes on. This truck's in good shape. It's very straight for the year and we've had it for a few years as I've said. So stayed tuned and we'll have more information as time goes on.Part Five: Installing Front & Rear Differential Guards (TF838 &TF839)Hi I'm Doug, your tech support representative here at Atlantic British. And as we continue on with Project D2, we're on to the next step. And what we have next in line is going to be the pair of differential guards, the front and rear diffs. Something that a lot of the guys overlook, but should you ever put a rock though your differential case and you want to be able to make it home, these would be advised to go that route. These will protect the differentials. They are cast metal so they can be dented. They can be punctured so to speak if you catch a good rock. So these are actually a good add on to add to your vehicle. We're trying to turn this into a really high level off-road vehicle, these will definitely assist in doing that. So what we have here is the front guard which is Terrafirma. This is the TF838. This comes with the bracket, 1 extra mounting bracket and your hardware. We have the rear kit, the TF839. Again with your guard, your attachment bracket and the hardware you need to attach that. The instructions are fairly simple. They do come with the kits. But we're going to show you basically how to install them right on our Project D2. Alright. Just to show you a test fit. You put the front guard over, we're going to slide that over in place. Now some vehicles may have a guard that loops around this back drag link, right at the back of the diff. And some don't. Now in this case this one does not. But there are 2 pre-drilled tap holes at the very end of the differential for that bracket. And we're going to use those 2 holes for the attachment in the back on the bottom. Now if it does not have that bracket, there's a good chance that those holes, and we're going to come around and we're going to show you those in just a second, id they're filled with mud or dirt or whatnot, you want to tap those out so that we have a nice clean thread when we go to put it in. The other thing you're going to want to do, and it even mentions it in the instructions, if you test slide this. Essentially you're going to be looking at how this bracket attaches to the back of this cover, and then these 2 holes will automatically line up with 2 top bolts in the back side of the diff. You're going to take those bolts out and then this gets bolted back in its place. So if you're not sure which 2 to take off, you can just test fit the bracket towards the back, it's going to line up with the 2. Those are the 2 you're going to remove and it's even listed in the instructions. Now just quickly too, I'm going to mention, they actually give you a list of tools required, before you go to install it. So it would be a good idea to dig these tools out and have these ready for you before you install. You have a 9/16th deep socket or spanner wrench, you can use either. 15 millimeter socket. And you can do that in either half inch or 3/8th inch drive. A 13 millimeter wrench. A ratchet for your socket. Again, 3/8th or half inch. And then a 6 to 12 inch extension. Those tools will easily install this cover. It's just a matter of a few bolts. Now on some of these vehicles you're going to have a U shaped bracket that wraps around this drag link and they're going to be bolted through to these 2 holes right here. You can see that this vehicle did not come equipped with it, and sure enough, the holes have gotten dirt and mud packed up inside there. You don't want to run the bolts for the new bracket up in there, so you're just simply going to take a chaser, and you can get a socket that fits the backside. That makes it a little bit easier. And you're just basically going to run it up in there and you're going to want to clean that mud out of there. Doesn't even hurt to spray a little bit of penetrating lube in there, and as that drips out it's going to take a lot of the dirt and garbage that's built up in there out. You may have to run it a couple times in there until you don't really feel much grit as you run through there. I can actually see it fall out of the hole as I run this in. And it goes in fairly easy because we're just dealing with a little bit of dirt. Alright. Going to shoot a little penetrating oil in there and the essentially all we need to do with this is we're going to take the 2 top bolts out. We're going to line up the bracket. We're going to see that we are basically dealing with there's a bolt that if you're facing the back of the differential you have a bolt at say 11:30 and another bolt at 1 o'clock. You're going to take those 2 out. Insert your bracket. Put your main bracket on. Run the 2 bolts. You're basically done. Alright, so, before we tighten everything up and this it what I wanted to explain, put the shields on, don't go tightening everything first thing. I put to 2 bolts on, lock them on. You want to basically get all the bolts started. You have the 2 bolts here in the back. The threads have been cleaned out. They're started. You have the bolt and the flat washer. And then up top, where the small accessory bracket bolts on, we've got the 2 bolts in the diff back in place. Couple threads started there. And then we've got the 2 nuts and bolts that hold the accessory bracket onto the guard itself. Now with everything being loose, we've got everything started. Now we can just tighten it all up and you're going to be in and then we're going to do the rear as well. Alright, so we're going to do the rear, and essentially what I'm going to do is hang it in place because the application is the same as the front. You've got 2 bolts down here at the very bottom of the differential case. These 2 bolts actually hold an anti-vibration weight on here. Some vehicles may have it, some may not. But if you have it, you run the 2 bolts out we're going to be starting with clean thread so it shouldn't be a problem there. And again the shield wraps around. You have a small add-on bracket on top and you're going to run those are going to line up with 2 top bolts on the differential, you're going to run the 2 nuts and bolts from the bracket to the add-on bracket. And essentially tighten everything down exactly like we did with the front. So I'll set everything in place, and we'll give you a look at it before we tighten everything up. So here we are with the back plate in place. As I said it's the same application as the front. You just have these 2 nuts and bolts that hold the 2 brackets together. You have the front of the small bracket being held by 2 bolts in the front of the pumpkin. And then on the bottom what we've done is omit that heavy weight that's back there and installed the bottom of this plate in place of that weight. As I said because that bolts already in there, you didn't have to go through the tap and die and all that. We blew penetrating oil and it ran right in. So you have a good solid protection there. Plus they give you access holes. So if you need to do a drain, which your drain plug is right here, and your fill plug here, you can still do maintenance without having to take the cover back off, which is a definite plus. So when you're ready to upgrade, put diff guards on your D2, and as again, follow along with us as we go along with Project D2, just call any of our knowledgeable salesmen at 1-800-533-2210. And thanks for watching.
